d. Follow the lighting instructions. Place the appliance being
inspected in operation. Adjust thermostat so appliance
shall operate continuously;
e. Test for draft hood equipped appliance spillage at the
draft hood relief opening after 5 minutes of main burner
operation. Use the flame of a match or candle;
f. After it has been determined that each appliance
connected to the venting system properly vents when
tested as outlined above, return doors, windows,
exhaust fans, fireplace dampers and any other gas
burning appliance to their previous conditions of use;
g. If improper venting is observed during any of the above
tests, the common venting system must be corrected.
Corrections must be in accordance with the latest edition of the
National Fuel Gas Code NFPA 54/ANSI Z223.1 and/ or CAN/ CSA
B149 Installation Codes.
If resizing is required on any portion of the venting system, use
the appropriate table in the latest edition of the National Fuel
Gas Code ANSI Z223.1 and/ or CAN/ CSA B149 Installation Codes.
THERM OSTAT LOCATION
In an area having good air circulation, locate the thermostat
about five feet high on a vibration-free inside wall. Do not install
the thermostat where it may be influenced by any of the follow-
ing:
• Drafts, or dead spots behind doors, in corners, or under
cabinets.
• Hot or cold air from registers.
• Radiant heat from the sun.
• Light fixtures or other appliances.
• Radiant heat from a fireplace.
• Concealed hot or cold water pipes, or chimneys.
• Unconditioned areas behind the thermostat, such as an
outside wall.
Consult the instructions packaged with the thermostat for mount-
ing instructions and further precautions.

WARNING
Improved construction and additional insulation in buildings have
reduced heat loss by reducing air infiltration and escape around
doors and windows. These changes have helped in reducing heat-
ing/ cooling costs but have created a problem supplying combus-
tion and ventilation air for gas fired and other fuel burning appli-
ances. Appliances that pull air out of the house (clothes dryers,
exhaust fans, fireplaces, etc.) increase the problem by starving
appliances for air.
House depressurization can cause back drafting or improper com-
bustion of gas-fired appliances, thereby exposing building occu-
pants to gas combustion products that could include carbon mon-
oxide.
If this furnace is to be installed in the same space with other gas
appliances, such as a water heater, ensure there is an adequate
supply of combustion and ventilation air for all appliances. Refer
to the latest edition of the National Fuel Gas Code NFPA 54/ANSI
Z223.1 or CAN/ CSA B149 Installation Codes or applicable provi-
sions of the local building codes for determining the combustion
air requirements for the appliances.
This furnace must use indoor air for combust ion. It cannot be in-
stalled as a direct vent (i.e., sealed combust ion) furnace.
M ost homes will require outside air be supplied to the furnace
area by means of ventilation grilles or ducts connecting directly
to the outdoors or spaces open to the outdoors such as attics or
crawl spaces.

WARNING
Category I Venting is venting at a non-positive pressure. A fur-
nace vented as Category I is considered a fan-assisted appliance
and the vent system does not have to be “gas tight.” NOTE: Single
stage gas furnaces with induced draft blowers draw products of
combustion through a heat exchanger allowing, in some instances,
common venting with natural draft appliances (i.e. water heat-
ers). All installations must be vented in accordance with National
Fuel Gas Code NFPA 54/ANSI Z223.1 - latest edition. In Canada, the
furnaces must be vented in accordance with the National Stan-
dard of Canada, CAN/ CSA B149.1 and CAN/ CSA B149.2 - latest edi-
tions and amendments.
NOTE: M asonry vent kit (M VK-01 and MVK-02) is to only be used
on interior masonry chimneys or qualifying exterior masonry
chimney applications identified in the M VK kit installation
instructions. To ensure safe and reliable operation, use only the
kit listed for your model.
