IMPORTANT INSTALLATION AND START-UP
PROCEDURES
Failure to follow this procedure may result in a nuisance smoke or odor
complaint.
The manifold pressure, gas rate by meter clocking, temperature rise and
operation must be checked after installation. Minor smoke and odor
may be present temporarily after start-up from the manufacturing
process. Some occupants are more sensitive to this minor smoke and
odor. It is recommended that doors and windows be open during the
first heat cycle.

This 4-way multipoise Category IV condensing furnace is CSA
design-certified as a direct-vent (2-pipe) or non-direct vent (1-pipe)
furnace. The furnace is factory-shipped for use with natural gas. The
furnace can be converted in the field for use with propane gas when a
factory-supplied conversion kit is used. Refer to the furnace rating plate
for conversion kit information.
This furnace is not approved for installation in mobile homes,
recreational vehicles, or outdoors.
This furnace is designed for minimum continuous return-air temperature
of 60°F (15°C) db or intermittent operation down to 55°F (13°C) db such
as when used with a night setback thermostat. Return-air temperature
must not exceed 80°F (27°C) db. Failure to follow these return-air
temperature limits may affect reliability of heat exchangers, motors, and
controls. See Fig. 3.

The furnace should be sized to provide 100 percent of the design heating
load requirement plus any margin that occurs because of furnace model
size capacity increments. None of the furnace model sizes can be used if
the heating load is 20,000 BTU or lower. Use Air Conditioning
Contractors of America (Manual J and S); American Society of Heating,
Refrigerating, and Air-Conditioning Engineers; or other approved
engineering method to calculate heating load estimates and select the
furnace. Excessive oversizing of the furnace may cause the furnace

and/or property damage.
When the furnace is installed in a residential garage, the burners and
burner ignition devices must be located at least 18 in. (457 mm) above
the floor. The furnace must be located or protected to avoid damage by
vehicles. When the furnace is installed in a public garage, airplane
hangar, or other building having a hazardous atmosphere, the furnace
must be installed in accordance with the current edition of NFPA
