A gas burner is a device that is designed to process the roof of a private or multi-storey building. With the help of a burner, roofing specialists melt roll materials, heating their surface, as well as dry and perform other types of work with bituminous materials.
What is a gas burner
The very design of a gas burner consists of parts such as a metal glass made of heat-resistant material; gas supply hose; a nozzle with which the flame is ignited even in strong winds. The gas burner is a fairly mobile design, equipped with convenient carrying handles. The weight of the device is approximately 1.5 kg.
The burner is usually filled with propane, the flow and length of the flame of which is regulated by means of a special valve. The burner is a fairly economical device, since a reducer is built into its design, with which you can adjust the fuel consumption. A special standby mode also allows you to save gas. The device is ignited with a lighter or matches, the optimal torch length for operation is 40-50 cm.
Burner use
Before proceeding with roofing work using a gas burner, it is necessary to clean the surface of roofing material or other material from dust and other types of contamination.
After carrying out the preparatory work, you can start marking the roofing material. To do this, lay out sheets of roofing material on the roof surface in such a way that the overlap between them is 10 cm.
After the marking work, the roofing material roll must be twisted again and the edges of the material must be fixed at the base of the roof using a gas burner. Gradually unwinding the roll of material, it should be carefully melted using the torch of the burner and pressed firmly against the roof surface.
When performing work, it is necessary to ensure that the roofing material lies down smoothly, without forming folds and bubbles. If the roofing material is laid on large areas, a special tool is used to level it - a hand roller.
A single charge of a gas burner is usually enough for 500-600 m of the length of the roofing material. At temperatures below +15, instead of a gas burner, it is customary to use a melting tool that runs on liquid fuel.
When carrying out roofing work with a gas burner, it is necessary to strictly observe safety precautions. It must be remembered that the burner is one of the most dangerous tools and the temperature of the fire at the outlet of its nozzle reaches 1200 ° C. It is strictly forbidden to leave the working area with the burner on.
