DANGER
FLAMMABLES
Flammable Vapors
Water heater has a main
burner flame.
The main burner flame:
1. which can come on
at any time and
2. will ignite flammable
vapors.
Vapors:
1. cannot be seen,
2. are heavier than air,
3. go a long way on the
floor and
4. can be carried from
other rooms to the
main burner flame by
air currents.
Vapors from flammable
liquids will explode and
catch fire causing death or
severe burns.
Do not use or store flammable
products such as gasoline,
solvents or adhesives in the
same room or area near the
water heater.
Keep flammable products:
1. far away from heater,
2. in approved containers,
3. tightly closed and
4. out of children's reach.
Installation:
Do not install water heater
where flammable products will
be stored or used unless the
main burner flame is at least
18" above the floor. This will
reduce, but not eliminate, the
risk of vapors being ignited
by the main burner flame.
Read and follow water heater warnings and instructions. If
owners manual is missing, contact the retailer or manufacturer.
