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. 50 .

Fig. 50 – Combustion Air and Vent Pipe Diameter Transition
Location and Elbow Configuration
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 .
NOTE: Maximum Equivalent Vent Length (MEVL) includes standard
and concentric vent termination and does NOT include elbows. Use
Table 13 – Maximum Equivalent Vent Length - Ft. (M)
NOTE:
1.40K Inducer Outlet Restrictor disk (P/N 337683-401; 1.25-in. (32 mm) Dia.) shipped in the loose parts bag or available through Replacement Components required under 10-ft. (3 M)
TEVL in all orientations. Required for installations from 0 - 2000 ft. (0 to 610 M) above sea level. Failure to use an outlet restrictor may result in flame disturbances or flame sense
lock-out.
2.60K Inducer Outlet Restrictor disk (P/N 337683-401; 1.25-in. (32 mm) Dia. available through Replacement Components) required for less than 5-ft. (1.5 M) TEVL in downflow and
horizontal orientations only. Required for installations from 0 - 2000 ft. (0 to 610 M) above sea level.
3. 120K Inducer Outlet Restrictor disk (P/N 337683-402 ; 1.50-in. (38 mm) Dia. available through Replacement Components ) required for less than 5-ft. (1.5 M) TEVL in downflow and
horizontal orientations only. Required for installations from 0 - 2000 ft. (0 to 610 M) above sea level.

NOTICE
!
OPTIONAL CONFIGURATION FOR COMBUSTION AIR INLET
PIPE
In applications where there is a risk of excessive moisture entering the
combustion air inlet pipe, a moisture trap may be added to the inlet pipe
to help prevent moisture from entering the furnace from the combustion
air inlet pipe. See Fig. 52 .
When sizing venting systems, the equivalent length of the optional
moisture trap (15 feet/5 M) must be taken into account.
