1. Use only with type of gas approved for this furnace. Refer to the
furnace rating plate.
2. Install this furnace only in a location and position as specified in the
"Location" section of these instructions.
3. Provide adequate combustion and ventilation air to the furnace
space as specified in "Air for Combustion and Ventilation" section.
4. Combustion products must be discharged outdoors. Connect this
furnace to an approved vent system only, as specified in the
"Venting" section of these instructions.
5. Never test for gas leaks with an open flame. Use a commercially
available soap solution made specifically for the detection of leaks
to check all connections, as specified in the "Gas Piping" section.
6. Always install furnace to operate within the furnace's intended
temperature-rise range with a duct system which has an external
static pressure within the allowable range, as specified in the
"Start-Up, Adjustments, and Safety Check" section. See furnace
rating plate.
7. When a furnace is installed so that supply ducts carry air circulated
by the furnace to areas outside the space containing the furnace, the
return air shall also be handled by duct(s) sealed to the furnace
casing and terminating outside the space containing the furnace.
See "Air Ducts" section.
8. A gas-fired furnace for installation in a residential garage must be
installed as specified in the warning box in the "Location" section.
9. The furnace may be used for construction heat provided that the
furnace installation and operation complies with the first
CAUTION in the LOCATION section of these instructions.
