Fig. 46 -- Pipe Vent and Combustion

Ventilated Combustion Air

The vent pipe for a Ventilated Combustion Air System must
terminate outdoors. See Fig. 44 for references to vent clearances

required by National code authorities. Allowable vent terminations
are shown in Fig. 40. The combustion air pipe terminates in a

well--ventilated attic or crawl space. Follow the clearances as

shown in Fig. 47.
The combustion air pipe cannot terminate in attics or crawl spaces

that use ventilation fans designed to operate in the heating season.
If ventilation fans are present in these areas, the combustion air

pipe must terminate outdoors as a Direct Vent System.

Non-Direct Vent / 1-Pipe System

The vent pipe for a Non Direct Vent (1--pipe) system must
terminate outdoors. See Fig. 44 for references to vent clearances

required by National Code authorities.

Allowable vent

terminations are shown in Fig. 40.
A combustion air inlet pipe to the outdoors is not required for a

Non--Direct (single--pipe) Vent System. A 12--in. long section of
pipe with a tight radius 2--in. (51 mm) 90 degree elbow is required

to be attached to the furnace. See Fig. 49. This short inlet air pipe
helps to ensure stable combustion, as well as allow for sound

attenuation. To aid sound attenuation, point the inlet air pipe away

from occupants. An extra elbow and/or five feet of pipe may be
used to accomplish the sound attenuation function.

Termination Requirements for the Provinces of Alberta and

Saskatchewan

The Provinces of Alberta and Saskatchewan require a minimum
unobstructed distance of 4 ft. (1.2 M) from the foundation to the

property line of the adjacent lot for vent termination of any

appliance with an input over 35,000 btuh. If there is less than 4 ft.
(1.2 M) of unobstructed distance to the property line of the

adjacent lot, no type of vent termination is permitted for appliances
with inputs greater than 35,000 btuh.
There are no additional restrictions on unobstructed distances

greater than 8 ft. (2.4 M). All single, two-pipe and concentric vents
may be used, providing all other Code and manufacturer’s

requirements in these instructions are adhered to. Refer to the
appropriate

Vent Termination

section above for locating the vent

termination
If the unobstructed distance from the foundation to the property
line of the adjacent lot is no less than 4 ft. (1.2 M) and no greater

than 8 ft. (2.4 M), it will be necessary to re-direct the flue gas
plume. In this situation, a concentric vent kit cannot be used. A

2-pipe termination (or single pipe termination when permitted) that
re-directs the flue gas away by use of an elbow or tee, certified to

ULC S636 from the adjacent property line must be used. See Fig.

49.
The concentric vent kit currently cannot be modified to attach an

elbow to the vent portion of the rain cap. A tee attached to the rain
cap could potentially direct the flue gas plume toward the intake air

stream and contaminate the incoming combustion air for the

furnace.
Refer to Fig. 49 for terminations approved for use in Alberta and

Saskatchewan.

Size the Vent and Combustion Air Pipes

General

Furnace combustion air and vent pipe connections are sized for
2-in. (50 mm ND) PVC/ABS DWV pipe. The combustion air and

vent pipe connections also accommodate 60 mm polypropylene
venting systems with outside diameters of approximately 60 mm

(2--3/8 inches). Any pipe diameter change should be made outside

furnace casing in vertical pipe. Any change in diameter to the pipe
must be made as close to the furnace as reasonably possible. See

Fig. 48.
The Maximum Vent Length for the vent and combustion air pipe

(when used) is determined from the Maximum Equivalent Vent
Length in Table 13 minus the number of fittings multiplied by the

deduction for each type of fitting used from Table 14.
