Roof burner: gas burner for roofing work. Device and principle of operation of gas burners Do-it-yourself gas roofing burner

The past decade was characterized by the emergence of revolutionary changes in the technology of arranging soft roofing. The classic roofing material has given way to modern built-up materials. The composition of the tool needed to perform roofing work has also changed. A bucket of bitumen and a brush ousted roof burner.

What is this equipment?

Gas-burner- an indispensable hand tool for performing work on the installation of soft roofing with modern welded materials. The flame torch, formed by the working burner, allows you to create local heating of the surface to perform the following operations on the roof:

drying wet areas of the underlying surface;
heating and melting of the lower bituminous layer of the deposited roll material.

In addition to performing work on the roof, a roofing gas burner is used:

for heating various products and materials to the required temperatures;
when soldering metals with light-alloy solders;
for burning old paintwork.

The device and principle of operation of the burner

The composition of the roofing gas burner includes the following elements:

The burner requires the following accessories to operate:

liquefied gas cylinder;
gas reducer - lowers the gas pressure from the cylinder to the working one (0.1 - 0.15 MPa), stabilizes the gas flow in the burner;
flexible hose - connects the burner to the outlet of the reducer.

The weight of the burner is small, no more than 1 - 1.5 kg. Many models have the ability to switch to standby mode, when, during short breaks in operation, the gas supply is reduced to a minimum, which allows the flame not to go out.

A convenient option that saves gas and eliminates the need to re-ignite the burner after breaks in operation. To ignite the burner, as a rule, an external source of flame is used: matches or a lighter.

Roof burner models

GGS-1- the simplest and most popular model. Flame length 600 mm. Versatility and low weight define a wide range of applications.
GG-2- the basic model of a gas burner. It has an excellent price-quality ratio. An excellent choice for do-it-yourself roofers.
GG-2U- the model is similar to GG-2, it differs in a shorter main tube. Convenient for working in hard-to-reach places.
GG-2S- the beginning of a professional series. The burner is adapted to work in strong winds.
GGK-1- has a weighted glass and a trigger gas supply mechanism.
GGS-4-1.0- has 4 cups, simultaneously covers the entire width of the roll with flame. Considerably accelerates work at large volumes of roofing works.

Application of gas burners

A gas burner is an almost indispensable tool for roofing work using welded materials. A well-chosen high-quality burner allows a team of two people to lay up to 60 rolls of welded material in one light day.

When performing work with an open flame, special attention should be paid to strict observance of all fire safety rules. So, if the area covered at a time exceeds 500 square meters, a prerequisite is the presence of fire hoses at the facility.

Access to the hoses from all four sides of the surface to be covered and the possibility of spilling water at any point of the covering to be laid should be provided.

Stages of work when laying material using a roofing burner

Works on the arrangement of the roof with rolled welded materials are carried out in several stages:

How to make a gas burner with your own hands?

Today, manufacturers offer a huge range of gas burners that can satisfy almost any user. But, there are times when a homemade tool takes its rightful place in the home workshop.

Making a gas burner with your own hands is quite feasible at home. If for one reason or another you cannot buy, make a burner, you can rent / rent.

What is required for this:

Gas jet with a nozzle passage diameter of 0.8 mm. The easiest way is to pick up from a used car carburetor. A set of additional jets are often equipped with home gas stoves.
Gas line - copper or brass tube 70 - 80 cm long. The diameter and wall thickness are selected so that it is possible to cut an internal thread from one end to secure the jet.
Wooden or plastic handle. A wide range of options. It should be nice and comfortable.
Glass - is the body of the burner and encloses the combustion zone. You can pick up a piece of thin-walled metal pipe with a length of 100 - 140 mm, an inner diameter of 25 - 40 mm. It can be made from sheet metal with a thickness of 0.8 - 1 mm. Connect the edges by welding or using rivets. Material for manufacturing - soft iron, copper, brass.
Control valve. Perhaps the most difficult question in the design. It should be easy to shut off the gas, be convenient to use. You can search among plumbing fittings, you can pick up from a home gas stove that has served its time.
Gas cylinder, reducer, flexible hose. You don't have to invent anything, just take it. These elements directly affect the issues of safe operation.

We assemble in the following sequence:

In the gas pipeline on one side we cut the internal thread and screw the jet.
We attach a glass to the same side of the tube from the outside. We use three spacers from improvised material.
Drilling a hole in the handle, insert the other end of the gas line into it and fix it with glue.
We connect the outlet of the control valve with the end of the line protruding from the back of the handle.
We connect the input of the control valve to the flexible hose, fix with a clamp.
We connect the second end of the flexible hose, reducer, gas cylinder.
We supply gas, we wait for now the gas will displace the air in the hose.
Ignite, regulate required flame length.

When making a burner with your own hands, you must remember that a gas burner is a tool of increased danger. Think carefully about each operation. It is necessary to exclude the possibility of gas leakage during the operation of a homemade burner.

Safety rules for working with gas burners for roofing

Performing work on the roof using a gas burner affects several sections of labor protection at once:

work at height;
work carried out with open fire;
handling of flammable substances.

To use strictly observing safety precautions is the basis for preserving human life and health.
Accordingly, the whole complex of security measures can be conditionally divided into three parts.
Measures to prevent a worker from falling from a height:

the presence of shoes that prevent the worker from slipping off the roof surface;
safety devices to prevent falls from a height;
the presence of fencing of the working area, walking bridges, etc.

Measures to protect workers from exposure to elevated temperatures:

the presence of special clothing, gloves;
the flame must not be directed towards people or elements of the gas installation;
you must not go outside the working area or climb the scaffolding with a lit burner in your hands.

Fire safety measures:

ensure the availability of primary fire extinguishing equipment in the working area;
work with an open flame can be carried out during daylight hours in the time interval from 8 to 18 hours;
no more than one liquefied gas cylinder can be in the working area at the same time;
it is necessary to exclude the heating of the gas cylinder;
prevent overheating and ignition of the deposited material.

Before starting work, it is necessary to inspect the gas equipment and make sure that it is working. Check the tightness of the connections of the cylinder, reducer, hose and burner.

conclusions

Practice shows that for the successful completion of any work, it is necessary to solve two main tasks:

carefully and comprehensively study the subject of the forthcoming work;
choose the right tool.

Knowledge gives 50% of success in the upcoming work, and a high-quality, wisely selected tool - 80%. Act, everything is in your hands!

When carrying out work on the installation and repair of the roof, there are situations when heating or drying of the material is necessary - for example, when laying a layer of waterproofing or erecting a soft roof, when you need to heat up the bitumen-based mastic. For these and many other purposes, a portable roofing gas burner is used.

With this device, you can perform several types of operations:

drying surfaces;

cutting or soldering metal elements;

firing the old layer of paint;

other work that requires heating to high temperatures.

The device and principle of operation of the burner

A roofing burner is a metal-based glass equipped with a nozzle and a plastic or wooden handle attached to the body.

The design of the gas burner cup is designed in such a way that the flame is protected from blowing out by the wind.

The flow of gas into the housing is carried out through a special gas pipeline. Mainly pressurized propane is used. The burner has a valve to regulate the amount of gas supplied. In addition, it is also possible to adjust the length of the flame.

In order to save gas consumption, roof burners have a special gearbox that controls the fuel consumption.

Absolutely all models of burners are equipped with an atmospheric air suction system.

To start the burner, use ordinary matches or a lighter.

Gas burners also provide a device for regulating operating modes. For example, most models have a standby mode, the purpose of which is to prevent wasted fuel during work breaks.

Since during operation roofing burners are heated to very high temperatures, only heavy-duty materials are used for their production.

The length of the handle for holding the burner should be no more than a meter. The device itself is very light: its weight ranges from 1-1.5 kilograms.

To prevent burns, the handles of the burners are equipped with a holder made of very durable wood species or heat-resistant plastic.

It should be noted that liquid fuel burners that run on fuel oil or diesel fuel can also be used for roofing.

Stages of work when laying material using a roofing burner

If roofing material is used as a waterproofing material, a gas burner is indispensable. It is also necessary to cover the roof with modern welded types of materials.

The whole process of working with the device can be divided into several stages.

First you need to prepare the base for further laying the material. To this end, it should be cleaned of debris. If necessary, it is also necessary to level the surface with a concrete screed.

After that, the rolled material is rolled out over the entire surface in such a way that adjacent sheets form an overlap with a width of 85 to 90 mm.

After completing the alignment and marking, the rolls must be rolled up again and strengthened at the base of the roof with a burner. By heating the lower part of the roll and the base of the roof with the help of a burner flame, the material is slowly rolled out, pressing it to the base.

To avoid the formation of wrinkles and air bubbles, it is necessary to run a hand roller over the attached canvas. At the final stage of work, a roofing gas burner is used to heat the seams of the overlapped material. After that, the seams should be rolled again with a hand roller.

When operating gas burners, you need to know a few important points:

the use of this device is possible at a temperature not lower than minus 15 degrees;

if work is carried out at a lower temperature, then you can use a liquid fuel burner;

when using a gas burner for laying roofing with high quality characteristics, from 500 to 600 m of roofing material can be laid per day;

since the work is carried out outdoors, the gas burner must provide a stable flame supply and reliably protect it from wind blowing.

Roof burner models

To carry out work on laying the roof, burners of different models are used.

GG-2 is the model name of the propane roof burner. The most suitable sample for self-taught masters performing repairs with their own hands. With high quality, it has a fairly moderate price.

GG-2U has similar characteristics. A distinctive feature of this model is a shortened version of the gas supply tube. It is ideal for work in hard-to-reach parts of the roof, as well as for gluing adjoining and joints.

GG-2S belongs to a series of professional equipment. This model runs on propane. Its main advantage is that the device can be operated even in strong winds. The device consists of two valves and two housings, and this makes it possible to regulate the operating modes with great accuracy.

GGS1-1.7– light weight, size and high performance make this model almost universal. It is used to dry the roof and fuse soft roofing materials on it. It is also successfully used in the implementation of waterproofing and some other types of work, which require a high-intensity flame to bring the surface temperature to 400 degrees.

The burner can be used for work on horizontally located sections of the roof, and on the junctions.

GGK-1– propane-air model. Its difference is a heavier and very durable glass.

This model is suitable for firing old paint, wood surfaces, for waterproofing work. Gas is supplied with a lever.

GGS1-1.0 it is used for small works of small volumes, arrangement of adjunctions. Suitable for operation on roofs with large angles of inclination. Also suitable for laying waterproofing.

GGS1-0.5 used for small repairs on the roof. Differs in economical fuel consumption.

Model GGS4-1.0 equipped with four sockets, which allow simultaneous heating of the roofing material over the entire width and non-stop rolling of the roll.

Due to the presence of special hooks on the edges of the device, heating and rolling of the roofing material can be carried out by one person. Using this model, you can significantly increase the productivity of the work carried out and reduce fuel consumption.

GV-3- a propane torch designed for heating metals, their welding, as well as hand soldering. Cup diameter - 50 mm.

GV-111R used for melting rolled bituminous materials, burning a layer of old paint.

GV-550, GV-900- very easy to use samples. They differ from each other in the maximum length of the flame. The second model makes it possible to work standing up, in full growth, since the length of its torch reaches 900 mm. The first model (GV-550) is more suitable for work at the roof junction points.

The GV model is suitable for heating non-ferrous and ferrous metals, melting rolled bituminous materials during waterproofing and roofing work, as well as a number of other works that require the use of a propane flame only.

GV 500 it is used for the implementation of welded work in the process of laying roofing materials. It can be used to melt bituminous materials. This model can heat the processed material up to 300 degrees.

GV-850- propane burner, equipped with a special valve, which makes it possible to regulate with high accuracy the amount of technical gas supplied from the cylinder. The model also has a lever with which the welder controls the length of the flame. This type of gas burner does not work on pure propane, but on a mixture, part of which is technical oxygen.

Safety rules for working with gas burners for roofing

When operating gas burners, safety rules must be strictly observed.

For roofing work, you need to change into special overalls and shoes with non-slip soles. You will also need some additional devices: navigation bridges, a belt, etc.

Before starting work, a thorough external inspection should be carried out to make sure that the gas burners, cylinders, connecting hoses are in full working order.

During the operation of the gas burner, only one gas bottle may be in the workplace. During operation, it is necessary to carefully monitor the tightness of the connection of cylinders and reducers with hoses.

During ignition of the burner, do not stand in front of the nozzle. The direction of the burner flame must be such that it does not touch nearby people, the gas bottle and the connecting hoses.

In the process of working with welded materials, it is necessary to ensure that they do not overheat and do not ignite. When heating the material with this device, it is necessary to ensure that only the lower part of the web is melted. The entire thickness of the material must not be allowed to soften.

The ignition of the burner must not be carried out from accidentally ignited objects. For this purpose, you can use only matches or a lighter.

When operating a propane burner model, the valve does not open a full turn, but half. After waiting a few seconds, the mixture can be ignited, and then proceed to adjust the length of the flame.

A worker with a lit burner in his hands does not have the right to go beyond the boundaries of the workplace or climb the scaffolding.

The gas burner is extinguished in two stages:

shut off the gas supply;

lower the lock lever.

In the event of a short interruption during operation, the burner must be extinguished. If a longer break is planned, then the gas supply should be stopped at the cylinder.

If the inlet channels of the mouthpieces are clogged, the device must not be operated, as kickbacks and pops may occur.

If, nevertheless, a backlash occurs or the burner overheats, it is necessary to stop work immediately and shut off the gas on the cylinder. The device itself should be cooled by immersing it in a container of water.

CONCLUSIONS

A gas burner is a device that is necessary for certain types of roofing work.

At its core, a gas burner is a metal glass with a nozzle and a handle.

There are many different models of roof burners. The choice is made in accordance with the type of work performed.

When using a burner, the amount of gas supplied, the length of the flame and the fuel consumption can be adjusted.

When working with a gas burner, you must strictly follow the instructions and follow the safety rules.

How the process of fusing roofing material with a gas burner can be seen in the video.

When performing roofing work and repairing the roof, waterproofing material is laid or bitumen-based mastics are melted. For drying and heating materials, a portable device such as a gas roofing burner is used.

In addition, burners are used in other works, including such operations as:

Heating to high temperatures of any products or workpieces;
Drying surfaces;
Soldering or cutting metals;
Burning old paint and other work that requires heating to high temperatures.

As a rule, a roofing burner is a metal cup equipped with a nozzle and supplemented with a wooden or plastic handle attached to the body. The burner cup is designed in such a way that it can protect the flame from being blown out by the wind.

The gas enters the housing through a gas supply hose, typically pressurized propane. The burner is equipped with a valve, with which it is easy to adjust the amount of gas supplied. In addition, it is possible to adjust the length of the flame.

To save propane consumption, roof gas burners are equipped with a special gearbox that controls fuel consumption. Almost all types of burners provide air suction from the atmosphere. Matches or a lighter are used to start the burner.

The burner is provided with a device that helps to regulate the operating modes. So, for example, many models have a standby mode so that during breaks in work they do not waste gas in vain.

During operation, the gas roofing burner heats up to high temperatures, so only high-strength materials are used for its production.

The length of the handle for which the master holds the burner is no more than one meter. At the same time, the burner itself is very light, its weight is 1-1.5 kilograms.

To protect against burns, a holder is made of high-strength wood or heat-resistant plastic on the handle of the burners.

In addition to the gas-air burners described, a liquid-fuel version of this equipment is also used in construction.

Such burners operate using fuel oil or diesel fuel, their device is somewhat different from that described above.

In an oil burner, fuel is fed into a high-pressure chamber where the liquid is atomized in the form of tiny particles. The fuel atomized in the air is ignited at the outlet and chamber with the formation of a stable flame.

It should be noted that a diesel burner has an advantage over a gas burner in that it can be operated at low temperatures.

Stages of work when laying material using a roofing burner

When using roofing felt as a waterproofing material, as well as when laying modern materials for built-up roofing, equipment such as a gas roofing burner is required.

All work can be divided into several stages:

Preparation of the base for laying the material. To do this, it is cleaned of debris, and, if necessary, leveled with a concrete screed.
Roll material is rolled out over the entire area of the roof so that adjacent sheets form an overlap of 85-90 mm wide. After leveling and marking, the rolls are rolled up again, strengthening them at the base of the roof with a burner.
By heating the base of the roof and the lower part of the roll with the flame of the burner, the material is slowly rolled out, pressing it to the base.
A hand roller is carried out along the reinforced canvas, trying to prevent the formation of air bubbles and folds.
At the last stage, a roofing gas burner is used to heat the seams of the overlapped material. After that, the seams are additionally rolled using a hand roller.

Advice! Carrying out work using gas burners is possible only if the air temperature outside is not lower than 15 degrees below zero. If it is necessary to carry out repairs at lower temperatures, an oil burner must be used.

Provided that a good quality gas burner is used in the work, it is possible to lay 500-600 meters of roofing material in a working day.

A high-quality burner must not only ensure the stability of the flame, but also be reliably protected from wind blowing, since the work takes place in the open.

Roof burner models

To perform roofing work, burners of various models are used. Among them:

GG-2 is a propane torch for roofing, which has an optimal ratio of quality and price. This model is suitable for home craftsmen who carry out roof repairs.
GG-2u - a model with similar characteristics, differs from the shortened gas supply tube described above, suitable for working in places with difficult access, gluing joints and junctions.
GG-2S - a model related to the professional series. This rooftop propane burner can work even under high wind load. The design of the burner consists of two housings and two valves, which allows you to more accurately control the operating modes.
GGK1 is a model that is distinguished by a heavier and more durable glass.
GRZH-1 is a burner that runs on liquid fuel.
GGS1-1.7 is a universal model, which is characterized by low weight and high performance.
GV-550 and GV-900 are convenient models that differ from each other in the maximum length of the torch. The GV-900 model forms a long torch (900 mm), so when using this model, you can work at full height. The GV-550 burner is designed to operate at roof junctions.

Safety rules for working with gas burners for roofing

Equipment such as a propane roof burner must be operated in compliance with a number of safety rules.

Roofing work can only be carried out in overalls and shoes with non-slip soles. In addition, it is necessary to use additional devices - a belt, navigation bridges, etc.
Before starting work, make sure by visual inspection that the roof burners, as well as gas cylinders and connecting hoses, are in good condition.
When using a burner, a single gas bottle must be available at the work site. During operation, make sure that the hose connections to the cylinder and the reducer are tight.
When igniting the burner, do not stand in front of the nozzle.
During operation, the flame of the burner must be directed so that it cannot touch people, the gas cylinder and the connecting hoses.
When working with welded materials, they must not be allowed to overheat and ignite.
When heating the material, it is necessary to achieve melting of only the lower part of the web, avoiding softening of the entire thickness of the material.
It is forbidden to ignite the burner from accidentally ignited objects, use matches or a lighter.
When igniting a propane burner, open the valve half a turn and, after a few seconds of purge, ignite the mixture. After that, you can begin to adjust the height of the flame.
If a lit roof burner is in the hands, the worker should not leave the workplace and climb the scaffolding.
The extinguishing of the burner is carried out in two stages. First, the gas supply is shut off, then the locking lever is lowered.
During a break in operation, the burner must be extinguished, and if the break is long, then the gas supply to the cylinder should be shut off.
If the inlet channels of the mouthpieces are clogged at the burner, work is prohibited, as there is a high risk of kickback and pops.
In the event of a kickback or overheating of the burner, work must be stopped immediately, the gas on the cylinder is shut off, and the burner itself is cooled in a container of water.

conclusions

Roofing equipment such as a gas or oil burner is a tool that allows you to significantly increase productivity in the installation of waterproofing and the construction of built-up roofing.

But, since this equipment is potentially dangerous, when working with it, you must strictly follow the instructions given by the manufacturer, and be sure to comply with all safety requirements when working with gas equipment.

Gas burners have long and firmly entered the life of construction: they cut and solder metal elements; burn the old layer of paint; dry surfaces. They are also used in other works, but most often gas burners are used for roofing. They heat the bitumen and process the seams of the covered roof surfaces. A propane burner is mainly used, that is, propane gas powered.

A gas burner for a roof is a propane tank and a torch with a hose. How gas enters through the hose and ignites is understandable. But what really needs to be noted is system supermobility and, in fact, reliability in use.

Gas cylinders can be of different capacities, but the hose and torch are the same. It is quite easy to control the flame because all the regulators are on the torch and therefore it is not necessary to be distracted by the setting during operation.

Several models of roof burners

Today there are quite a lot of models. What are they for and what models are they:

A roofing gas burner and a propane gas burner are outwardly indistinguishable, but two different classes are separated.

The difference between one type and another is in the use of cylinders: for propane there are standard ones used in everyday life and in welding work. They are quite easy to refuel - more precisely, you just need to change them at gas stations. Guided by certain principles of choice, one should note the difference in flame power and temperature(propane has more), and versatility - the ability to use when soldering and crimping pipes.

There is also a diesel roofing burner, which is a little safer than its relatives, but still, at the price of the fuel used, it did not take root, at least in private construction.

Step-by-step process of working with a roofing gas burner

The process of working with a roofing gas burner is a phased coating of the roof with insulation. One of the main elements of the coating is roofing material.

Rules to know

it is impossible to work with a gas burner if the air temperature below -15 degrees Celsius;
at temperatures below -15 degrees Celsius, a diesel burner is used;
using a gas burner for roofing, you can cover an area of up to 500 square meters;
at the device for a roof it is necessary reliable wind protection and a stable flame when fuel is supplied from a gas cylinder.

Propane or Gas Torch Safety Precautions

Although everyone knows how to use burners, safety measures are never superfluous, but they consist of the following rules:

Conclusion

Roofing propane or gas burners are designed for roofing work on some types of roofs.
What is a gas burner for roofing - this is a glass with an attached handle and inside of which there is a nozzle.
Devices are selected according to the type of work performed.
Roofing burners allow, if necessary, to adjust the length of the flame and the gas flow.
When working with the device, follow the rules and safety measures.

A gas burner for roofing is an indispensable tool when waterproofing a roof surface is required. Before use, it is recommended to familiarize yourself with the principle of application and some of the nuances that will prevent burns and the occurrence of unforeseen situations.

Gas burner device

For the arrangement of a soft roof, experts recommend using burners that have one nozzle. This ensures the most uniform heating of the material, in addition, it will be possible to save fuel. According to professionals in their field, devices with several nozzles heat up unevenly. When working, you may notice the burnout of the canvas in one place, while in another the material will not be warmed up enough. According to external characteristics, the burner is a glass equipped with a nozzle. The handle is attached to the latter. The glass is made in such a way that during operation the flame does not die out from the effects of wind. A rubberized material is used for the handle, which is sometimes replaced with hardwood. The standard length of such a device does not exceed 1 meter, while the weight, as a rule, is not more than 1.5 kilograms.

Some nuances of use

If you will be using a gas burner for roofing, then you must consider that the flame control is triggered. This applies to gas-air structures. In this case, you can quickly switch between modes. This is to the liking of all masters who quite often use the change of operating mode to economical. If you are interested in saving gas, then you can put the device into standby mode.

A reducer is used to reduce propane consumption. It is designed to stabilize the flow of fuel, which allows you to control the flow. If you want to save resources, then you should purchase equipment with a gearbox that provides a 30% reduction in gas consumption. Combustion air is usually sucked in from the atmosphere. If the burner is in good condition, and also reliably protected from the effects of wind, then with its help it is possible to lay 600 meters of roofing material within 8 hours.

Instructions for use

If you will be using a gas burner for roofing, then you must first carry out several steps. Initially, the base is prepared for laying the material, for this the surface is cleaned of dust and debris. If there is a need, then the concrete screed should be leveled. Next, the surface is treated with a primer. At the next stage, you can start working with rolled material, which is laid out with an overlap. The width of the latter can vary from 8.2 to 9 cm. Such a waterproofing installation is only a fitting. During these manipulations, the rolls should be aligned, and then rolled back. The material must be fixed at the base of the roof, during which a gas burner for roofing is used. Now the assistant should be connected to work. One of the craftsmen warms up the surface of the base with the help of equipment, as well as the lower surface of the waterproofing. While the second person is engaged in tightly pressing the insulation to the roof surface. In this case, the roll will have to be rolled out immediately. In order to avoid the formation of wrinkles and bubbles, the roll should be rolled with a hand roller. If delamination of the seams was found, then the gas burner for roofing, the photo of which is presented in the article, will eliminate these errors.

Safety instructions

The master must remember that the described equipment is very dangerous if used incorrectly. In the process of manipulation, you will have to work with open fire. Any such equipment requires compliance with certain safety regulations. Thus, in no case should you smoke in the workplace. Work should be carried out only after the cylinders, hoses, and gas burner have been checked for serviceability and suitability for operation. A gas burner for roofing must have sealed hoses. This also applies to the connecting elements between the cylinder and the burner. Do not start work if there is no special equipment available. This is especially true for safety shoes that have non-slip soles. It is unacceptable to place several gas cylinders on the roof surface at the same time during the described manipulations. A gas burner for roofing, the instructions for use of which are described in the article, is a fire hazardous equipment. That is why, before laying the insulation, a sufficient number of fire extinguishers should be prepared, the operability and serviceability of which should be checked in advance.

Operating rules

In addition to special shoes, the master must have overalls, as well as a belt and walking bridges. During the ignition of the equipment, it is forbidden to stand directly in front of the nozzle. The direction of the flame must be directed in such a way that it does not reach people on the roof. It is important to prevent fire from coming into contact with the connecting hoses and the gas cylinder. A gas burner for roofing, the drawing of which is presented in the article, should be used according to a technology that involves the exclusion of overheating and ignition of the materials being laid. When heating the insulation using the described equipment, it is necessary to ensure that only the lower surface of the web is melted. Softening of the entire thickness of the material is unacceptable. If you use a gas burner for roofing, you can waterproof the roof system with your own hands. However, it is unacceptable to set fire to equipment with the help of accidentally ignited objects. To do this, use only a lighter or matches.

In the process of using a propane model, the valve should not be opened a full turn, but only half. After the specialist waits a few seconds, ignition can be performed. After that, you can move on to adjusting the length of the flame. A worker in whose hands a lit burner is located must not leave the boundaries of the workplace, and also use scaffolding for movement.

Final works

The equipment must be extinguished in two stages: first, turn off the gas supply. The next step is to lower the lock lever. If you plan to interrupt the work process for a certain period of time, then the burner should not be left unattended. During this period, it should be extinguished. If you have planned a longer break, then the gas supply should be stopped on the cylinder.

Prevention of unforeseen situations

If clogging of the inlet channels of the mouthpieces has been found, the equipment must not be operated. Failure to follow this rule may result in clapping and kickbacks. If, nevertheless, this happened (a similar situation, by the way, can also occur when the burner overheats), then it is recommended to stop work immediately and also turn off the gas. The device must then be cooled by immersion in a tank of water.

Features of different burner models

After reading this article, you will understand what a gas burner for roofing looks like. However, it is also worth knowing that various modifications can be found on sale. For example, GG-2 is used by amateur craftsmen and is intended for work in small volumes. If you see a model of the GG-2 brand on sale, you will know that it differs from those described above only in a shortened gas pipeline. This equipment is simply indispensable for manipulations in hard-to-reach places. With it, you can glue the adjunctions and joints. If you are going to do the work professionally, then the latest model will be a must for you.

Conclusion

When choosing equipment for laying insulation, it is worth checking whether the device has a reducer for a gas burner for roofing. This part of the design allows the fuel to be used more economically. You should not save money by purchasing models without such an add-on, because it can justify a slightly more impressive cost after some time of using the described equipment. Whereas if there is a need to waterproof only one roof, then it is not at all advisable to purchase a burner. It would be preferable to rent equipment. It will be cheaper, and therefore more profitable. Many masters use this approach.
