environments can cause a variety of problems
within the furnace and may significantly
reduce the life or the performance of the
furnace. Therefore operating the furnace during
construction is not permitted and will void the
warranty.
COMBUSTION AIR & VENTING
REQUIREMENTS
WARNING:
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 with each
individual appliance connected to the venting
system being placed in 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 Natural Gas and
Propane 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 spaces of the building.
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 being inspected into operation.
Adjust the thermostat so appliance is operating
continuously.
7. Test for spillage from draft hood equipped
appliances at the draft hood relief opening after 5
minutes of main burner operation. Use the flame
of a match or candle.
8. 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 Z223.1/NFPA 54 Natural Gas and Propane
Installation Codes.
9. 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-fired burning appliance to their
previous conditions of use.
IMPORTANT INFORMATION:
• Provisions must be made during the installation of
this furnace that provide an adequate supply of air
for combustion. Furnace installation using methods
other than those described in the following sections
must comply with the National Fuel Gas Code (NFGC)
and all applicable local codes.
• Instructions for determining the adequacy of
combustion air for an installation can be found in the
