their instructions.
If you cannot reach your gas provider, call the fire

department.
Do not return to your home until authorized by your gas

supplier or the fire department.
Do not use or store flammable products, such as gasoline,
solvents, or adhesives in the same room or area as the
boiler.
The boiler has a main burner flame that can turn on at
●
any time and can ignite flammable vapors. Vapors from
flammable liquids can explode and catch fire, causing death
or severe burns.
Vapors cannot be seen and are heavier than air. They can
●
travel long distances along the ground and can be carried
from other rooms to the boiler's main burner flame by air
current.
Keep all flammable products far away from the boiler and
●
store them in approved containers. Keep the containers
closed tightly and out of the reach of children and pets.
