appliance not connected to the venting system. Turn on
any exhaust fans, such as range hoods and bathroom
exhausts, so they shall operate at maximum speed. Do
not operate a summer exhaust fan. Close fireplace
dampers;
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 Appendix G in the latest edition of the National
Fuel Gas Code ANSI Z223.1 and/or CAN/CSA B149 Installation Codes.

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 following:
•
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.

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 ap-
pliances 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 the other 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 pro-
visions of the local building codes for determining the combustion
air requirements for the appliances.
This furnace must use indoor air for combustion. It cannot be installed
as a direct vent (i.e., sealed combustion) furnace.
Most 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.

Category I Venting is venting at a non-positive pressure. A furnace
vented as Category I is considered a fan-assisted appliance and the
vent system does not have to be “gas tight.” NO

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 heaters). All instal-
lations 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 Standard of Canada,
