WARNING
Keep the area around the furnace clear
and free from combustible materials,
gasoline, and other flammable vapors
and liquids.
Do not use this furnace if any part has
been under water. Immediately call a
trained and qualified professional to
inspect the furnace and to replace any
part of the control system and any gas
control which has been under water.

Any safety screen or guard removed for

Prevent dust from accumulating on the

the furnace.
Do not sit on the furnace.
Do not place containers of liquid on top of
