5. 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 sup-
ply.
6. 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 con-
trols, control system parts, electrical parts that have been wet or the
furnace if deemed necessary.
7. NEVER . . . Store flammable materials of any kind near your fur-
nace. Gasoline, solvents, and other volatile liquids should be stored
only in approved containers outside your home. These materials
vaporize easily and are extremely dangerous.
8. NEVER . . . Store cleaning materials near your furnace. Materials
such as bleaches, detergents, powdered cleansers, etc., can cause
corrosion of the heat exchangers. 
9. NEVER . . . Use the area around your furnace as a storage area for
items which could block the normal flow of air. This flow of air is
required for ventilation of the various furnace components.
INSTRUCTIONS FOR EXAMINING THE

Examine the furnace as outlined below in steps “1 - 8” before each
heating season. Use Figures 1 - 4 for visual reference.
