Safety in case of a burner with propane bottle
Propane is a pure and environmentally friendly fuel. The HOAF WeedAir® 50/75i
will almost completely burn it up into carbon dioxide and water. If the HOAF
WeedAir® 50/75i is operated correctly, use of the HOAF WeedAir® 50/75i is
completely safe. However, always take the following precautions:
• Propane becomes explosive when mixed with air. Therefore, HOAF WeedAir®
50/75i must be treated with great care. Should you observe any damage to
the gas supply, immediately switch off the HOAF WeedAir® 50/75i. Do not
start using the HOAF WeedAir® 50/75i until all damage has been repaired by
professionals.
• Propane is heavier than air and will therefore accumulate in lower situated
cavities or basements. Therefore, do not store HOAF WeedAir® 50/75i over
channel shafts, etc.
• Always store the HOAF WeedAir® 50/75i in a well-ventilated room and never
in a basement.
• Carefully observe the instructions of your gas supplier concerning storage,
transport and the filling of propane tanks.
• Only fill the propane tanks in the open air, using equipment provided by your
gas supplier. It is absolutely forbidden to smoke or have open fire nearby
during filling.
• Always keep the fire extinguisher at hand.
2.6 Safety devices
Hose rupture valve:
The HOAF WeedAir® 50/75i features a
hose rupture valve in order to prevent any
risk of gas leaks, e.g. if the gas hose is
damaged. If there are any leaks, this valve
will immediately block the gas supply to
the burner. The configuration depends on
the actual pressure controller.
