3. Combustion & Ventilation Air
For Single Pipe Installation
When the installation is complete, check that all appliances have
adequate combustion air and are venting properly. See Venting
And Combustion Air Check in "4. Gas Vent Installation"Section in
this manual.
CARBON MONOXIDE POISONING HAZARD.
Failure to provide adequate combustion and
ventilation air could result in death and/or personal
injury.
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 8.3, Air for Combustion and Ventilation, of the National
Fuel Gas Code, (NFGC), ANSI Z223.1-2002/NFPA 54-2002
in the U.S.,
2. Sections 7.2, 7.3, 7.5, 7.6, 7.7, and 7.8 of National Standard of
Canada, Natural Gas and Propane Installation Code
(NSCNGPIC), CSA B149.1-00 in Canada,
3. Applicable provisions of the local building code.
Outdoor Combustion Air Method
A space having less than 50 cubic feet per 1,000 BTUH input rating
for all gas appliances installed in the space requires outdoor air for
combustion and ventilation.
Air Openings andConnecting Ducts
1. Total input rating for all gas appliances in the space MUST be
considered when determining free area of openings.
2,
3.
4.
5.
Connect ducts or openings directly to the outdoors.
When screens are used to cover openings, the openings
MUST be no smaller than 1/4" mesh.
The minimum dimension of air ducts MUST NOT be less than
When sizing a grille, louver, or screen use the free area of
opening. If free area is NOT stamped or marked on grill or lou-
ver, assume a 20% free area for wood and 60% for metal.
Screens shall have a mesh size not smaller than 1/4".
Requirements
1. Provide the space with sufficient air for proper combustion and
ventilation of flue gases using horizontal or vertical ducts or
openings.
2. Figure 5 illustrates how to provide combustion and ventilation
air when two permanent openings, one inlet and one outlet, are
used.
This furnace can NOT be common vented or connected to any
type B, BW or Lvent or vent connector, nor to any portion of a facto-
ry- built or masonry chimney. Ifthis furnace is replacing a previous-
ly common-vented furnace, it may be necessary to resize the
existing vent and chimney to prevent oversizing problems for the a.
other remaining appliance(s). See "Venting and Combustion Air
Check"in this section, This furnace MUST be vented to the out-
side. b.
Outside Air (This is ONLY a guide. Subject to codes of country having jurisdiction.)
One opening MUST commence within 12" of the floor
and the second opening MUST commence within 12" of
the ceiling.
Size openings and ducts per Table 1.
