1. Make sure that the furnace area is clear and free of combustible
materials, gasoline and other flammable vapors and liquids.
2. For proper operation of this furnace, air for combustion and ventila-
tion is required. Make sure that these openings are not obstructed.
3. For lighting or shutting down this furnace, refer to the lighting
instructions provided adjacent to the burners and also located in
this manual.
4. A roll-out switch is provided in the burner compartment. This switch
is a manual reset. If the furnace fails to operate, contact a qualified
service agency.
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. Then call a qualified service technician.
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 to replace all gas
controls, control system parts, electrical parts that have been wet or
the furnace if deemed necessary.
7. Prior to each heating season inspect the flue gas vent and the
return and supply air duct and ensure that the equipment is well
supported and there are no signs of deterioration. The manufac-
turer recommends that main burner, ignition device and controls are
inspected by a qualified furnace technician before each heating
season.
This heating/cooling unit is designed for outdoor use and can be
installed anywhere from grade level to the roof. Electric air conditioning
in the summer electric heat pump heating, and gas heating in the winter
- all from a single unit.
8. Do not allow snow to accumulate near the furnace where it could
block the flue gas vent or the combustion air intake.
