Installer’s Guide
The following safety practices and precautions must be
followed during the installation, servicing, and opera-
tion of this furnace.
1. Use only with the type of gas approved for this fur-
nace. Refer to the furnace rating plate.
2. Install this furnace only in a location and position as
specified in “Location and Clearances” (page 4), of
these instructions.
3. Provide adequate combustion and ventilation air to
the furnace space as specified in “Air for Combus-
tion and Ventilation” (pages 8-9), of these instruc-
tions.
4. Combustion products must be discharged outdoors.
Connect this furnace to an approved vent system
only, as specified in the “Venting” section (pages 13-
15), of these instructions.
5. Never test for gas leaks with an open flame. Use a
commercially available soap solution made specifi-
cally for the detection of leaks to check all connec-
tions, as specified in “Gas Piping” (page 618), of
these instructions.
6. Always install the 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 on the unit
rating plate. Airflow with temperature rise for cfm
versus static is shown in the Service Facts accom-
panying this furnace.
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 a duct(s) sealed to the fur-
nace casing and terminating outside the space con-
taining the furnace.
8. A gas-fired furnace for installation in a residential
garage must be installed as specified in “Location
and Clearances” section (page 4), of these instruc-
tions.
9. The furnace may be used for temporary heating of
buildings or structures under construction only
when the following conditions have been met:
a. The furnace venting system must be complete
and installed per manufacturer’s instructions.
b. The furnace is controlled only by a room thermo-
stat (no field jumpers).
c. The furnace return air duct must be complete and
sealed to the furnace and clean air filters are in
place.
d. The furnace input rate and temperature rise
must be verified to be within nameplate mark-
ing.
e. 100% of the furnace combustion air requirement
must come from outside the structure.
SAFETY SECTION
CARBON MONOXIDE POISONING HAZARD
Failure to follow the steps outlined below for each
appliance connected to the venting system being
placed into operation could result in carbon monoxide
poisoning or death.
The following steps shall be followed for each appliance
connected to the venting system being placed into
operation, while all other appliances connected to the
venting system are not in operation:
1. Seal any unused openings in the venting system.
2. Inspect the venting system for proper size and horizontal
pitch, as required in the National Fuel Gas Code,
ANSI Z223.1/NFPA 54 or the CAN/CGA B149
Installation Codes and these instructions. Determine
that there is no blockage or restriction, leakage,
corrosion and other deficiencies which could cause an
unsafe condition.
3. As far as practical, close all building doors and windows
and all doors between the space in which the
appliance(s) connected to the venting system are
located and other deficiencies which could cause an
unsafe condition.
4. Close fireplace dampers.
5. Turn on clothes dryers and any appliance not connected
to the venting system. Turn on any exhaust fans, such
as range hoods and bathroom exhausts, so they are
operating at maximum speed. Do not operate a summer
exhaust fan.
6.
Follow the lighting instructions. Place the appliance be-
ing inspected into operation. Adjust the thermostat so
appliance is operating continuously.
7. If improper venting is observed during any of the above
tests, the venting system must be corrected in
accordance with the National Fuel Gas Code,
ANSI Z221.1/NFPA 54 and/or CAN/CGA B149
Installation Codes.
8.
After it has been determined that each appliance
connected to the venting system properly vents where
tested as outlined above, return doors, windows, exhaust
fans, fireplace dampers and any other gas -fired burning
appliance to their previous conditions of use.
WARNING
!
f. The furnace return air temperature range is be-
tween 55 and 80 degrees Fahrenheit.
g. Clean the furnace, duct work, and components
upon substantial completion of the construction
process, and verify furnace operating conditions
including ignition, input rate, temperature rise
and venting, according to the manufacturer’s in-
structions.
10. This product must be gas piped by a Licensed
Plumber or Gas Fitter in the Commonwealth of
Massachusetts.
