CAUTION: Combustion air must not be taken from
inside structure because inside air is frequently contami-
nated by halogens, which include fluorides, chlorides,
bromides, and iodides. These elements are found in
aerosols, detergents, bleaches, cleaning solvents, salts, air
fresheners, adhesives, paint, and other household prod-
ucts. Locate combustion-air inlet as far as possible from
swimming pool and swimming pool pump house.
Excessive exposure to contaminated combustion air will
result in safety and performance related problems.

TABLE 5—COMBUSTION-AIR AND VENT PIPE TERMI-
Above grade level or above
anticipated snow depth
From plumbing vent stack
From any mechanical fresh air intake
For furnaces with an input capacity of
100,000 Btuh or less—from any non-
mechanical air supply (windows or doors
which can be opened) or combustion-air
For furnaces with an input capacity greater
than 100,000 Btuh or less—from any non-
mechanical air supply (windows or doors
which can be opened) or combustion-air
From service regulator vent, electric and
gas meters and relief equipment
Above grade when adjacent to public
* Horizontal distance.
† 18 in. above roof surface in Canada.
‡ 36 in. to electric meter in Canada only.
NOTES:
1. If installing 2 adjacent 350MAV Furnaces, refer to Multiventing and Vent
Terminations section for proper vent configurations.
2. When locating combustion-air and vent terminations, consideration must be
given to prevailing winds, location, and other conditions which may cause
recirculation of the appliance's own flue products or the flue products of
adjacent vents. Recirculation can cause poor combustion, inlet condensate
problems, and accelerated corrosion of heat exchangers.
3. Vent termination can not terminate less than 2 ft horizontal and 7 ft above
public walkway or where condensate vapor or droplets may be a hazard.
