Install this furnace only in a location and position as specified in
LOCATION and INSTALLATION sections of these instructions.
Always provide adequate combustion and ventilation air as speci-
fied in section Combustion Air and Vent Pipe Systems of these
instructions to furnace.
Combustion products must be discharged outdoors. Connect this
furnace to an approved vent system only, as specified in the
Combustion Air and Vent Piping sections of these instructions.
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
of these instructions.
Always install furnace to operate within the furnace’s intended rise
range with a duct system which has an external static pressure
within the allowable range, as specified in the SET TEMPERA-
TURE RISE section of these instructions and furnace rating plate.
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.
A gas-fired furnace for installation in a residential garage must be
installed as specified in the Hazardous Locations section of these
instructions.
The furnace may be used for construction heat provided that the
furnace installation and operation complies with:
•
The furnace is permanently installed with all electrical wiring,
piping, air filters, venting and ducting installed according to
these installation instructions. A return air duct is provided,
sealed to the furnace casing, and terminated outside the space
containing the furnace. This prevents a negative pressure
condition as created by the circulating air blower, causing a
flame rollout and/or drawing combustion products into the
structure.
•
The furnace is controlled by a thermostat. It may not be
″
hot
wired
″
to provide heat continuously to the structure without
thermostatic control.
•
Clean outside air is provided for combustion. This is to
minimize the corrosive effects of adhesives, sealers and other
construction materials. It also prevents the entrainment of
drywall dust into combustion air, which can cause fouling and
plugging of furnace components.
•
The temperature of the return air to the furnace is maintained
between 55°F (13°C) and 80°F (27°C), with no evening setback
or shutdown. The use of the furnace while the structure is under
construction is deemed to be intermittent operation per our
installation instructions.
•
The air temperature rise is within the rated rise range on the
furnace rating plate, and the firing rate has been set to the
nameplate value.
•
The filters used to clean the circulating air during the construc-
tion process must be either changed or thoroughly cleaned prior
to occupancy.
•
The furnace, ductwork and filters are cleaned as necessary to
remove drywall dust and construction debris from all HVAC
system components after construction is completed.
This furnace is shipped with the following materials to assist in
proper furnace installation. These materials are shipped in the main
blower compartment.
