4. Replace venter gasket (part # 1013540, if needed) to venter
assembly with adhesive in the same location as the old one.
5. Rotate venter assembly 90 ° right or left from original location
depending on venting configurations.
6. Tighten the four(4) screws that secure the venter assembly to
the collector box. Do not overtighten. Do tighten screws
enough to compress venter gasket.
7. Replace power leads to venter motor and reconnect hose to
pressure switch.
NOTE: Unused open vent hole must be covered. A Vent Cover is
supplied with Vent Pipe Shield Kit NAHA002VC. A
55/16"
(135mm) diameter Vent Cover can be fabricated with sheet metal
for all side vent installations.
4. Combustion & Ventilation Air
CARBON MONOXIDE POISONING HAZARD
Failure to provide adequate combustion and
ventilation air could result in personal injury or
death.
Use methods described here to provide
combustion and ventilation air.
Furnaces require ventilation openings to provide sufficient air for
proper combustion and ventilation of flue gases. All duct or open-
ings for supplying combustion and ventilation air must comply with
the gas codes, or in the absence of local codes, the applicable na-
tional codes.
Combustion and ventilation air must be supplied in accordance
with one of the following:
1. Section 9.3, Air for Combustion and Ventilation, of the Nation-
al Fuel Gas Code, National Fuel Gas Code (NFGC), NFPA
54/ANSI Z223.1-2006 in the U.S.,
2,
Sections 8.2, 8.3, 8.5, 8.6, 8.7, and 8.8 of National Standard
of Canada, Natural Gas and Propane Installation Code
(NSCNGPIC), CSA B149.1-05 in Canada,
3. Applicable provisions of the local building code.
When the installation is complete, check that all appliances have
adequate combustion air and are venting properly. See Venting
And Combustion Air Check in "Gas Vent Installation" Section in
this manual.
ContaminatedCombustionAir
Installations in certain areas or types of structures could cause ex-
cessive exposure to contaminated air having chemicals or halo-
gens that will result in safety and performance related problems
and may harm the furnace. These instances must use only out-
door air for combustion.
The following areas or types of structures may contain or have ex-
posure to the substances listed below. The installation must be
evaluated carefully as it may be necessary to provide outdoor air
for combustion.
• Commercial buildings.
• Buildings with indoor pools.
• Furnaces installed in laundry rooms.
• Furnaces installed in hobby or craft rooms.
• Furnaces installed near chemical storage areas.
• Permanent wave solutions for hair.
• Chlorinated waxes and cleaners.
• Chlorine based swimming pool chemicals.
• Water softening chemicals.
• De-icing salts or chemicals.
• Carbon tetrachloride.
• Halogen type refrigerants.
• Cleaning solvents (such as perchloroethylene).
• Printing inks, paint removers, varnishes, etc..
• Hydrochloric acid.
• Sulfuric Acid.
• Solvent cements and glues.
• Antistatic fabric softeners for clothes dryers.
• Masonry acid washing materials.
Outdoor CombustionAir Method
A space having less than 50 cubic feet per 1,000 BTUH (4.8 cubic
meters per kW) input rating for all gas appliances installed in the
space requires outdoor air for combustion and ventilation.
