SECTION I: SAFETY
1.
The furnace area must be kept clear and free of combustible mate-
rials, gasoline and other flammable vapors and liquids.
2.
Insulating materials may be combustible. The furnace must be
kept free and clear of insulating materials. The furnace area must
be examined when installed in an insulated space or when insula-
tion is added to be sure that the insulation material has been kept
away from the furnace.
3.
Follow the instructions exactly as shown on the OPERATING
INSTRUCTION LABEL or the Start-up and Shutdown Instructions

furnace off.
4.
Should the gas supply fail to shut off or if overheating occurs, shut
off the gas valve to the furnace before shutting off the electrical
supply.
5.
Do not use this furnace if any part has been under water. A flood-
damaged furnace is extremely dangerous. Attempts to use the fur-
nace can result in fire or explosion. A qualified service agency
should be contacted to inspect the furnace and replace all gas
controls, control system parts, electrical parts that have been wet
or the furnace if deemed necessary.
