Dimensions are those required in Standard ASTM D-3311.

Example:

An 80,000 BTUH furnace requires 32 feet of pipe and five 90º elbows.
Using 2" pipe and standard elbows, the total equivalent length will be:

This exceeds the 65 foot maximum equivalent length of 2" pipe allowed
for that model and is thus not acceptable.

By using sweep elbows, the total equivalent length will be:

This is less than the 65 foot maximum equivalent length of 2" pipe
allowed for that model and is thus acceptable. 

Alternatively, using 3" pipe and standard elbows, the total equivalent
length will be:

This is less than the 90 foot maximum equivalent length of 3" pipe
allowed for that model and is thus acceptable.

COMBUSTION AIR AND VENT PIPING ASSEMBLY

The final assembly procedure for the combustion air and vent piping is
as follows:

1.

Cut piping to the proper length beginning at the furnace.

2.

Deburr the piping inside and outside.

3.

Chamfer (bevel) the outer edges of the piping.

4.

Dry-fit the vent piping assembly from the furnace to the outside ter-
mination checking for proper fit support and slope.

5.

Dry-fit the combustion air piping assembly checking for proper fit,
support and slope on the following systems:

a. Sealed combustion air systems from the furnace to the outside

termination.

b. Ventilated combustion air systems from the furnace to the attic or

crawl space termination.

6.

Disassemble the combustion air and vent piping, apply cement
primer and the cement per the manufactures instructions. Primer
and cement must conform to ASTM D2564 for PVC, or ASTM
D2235 for ABS piping.

7.

All joints must provide a permanent airtight and watertight seal.

8.

Install the combustion air and vent piping such that it has a 1/4” per
foot (21 mm/m) grade so that condensate flows back toward the fur-
nace. Piping should be supported with pipe hangers to prevent sag-
ging.

9.

Seal around the openings where the combustion air and / or vent
piping pass through the roof or sidewalls.

IMPORTANT

Furnace vent pipe connections are sized for 2” (5.1 cm). pipe. Any
pipe size change must be made outside the furnace casing in a verti-
cal pipe section to allow proper drainage of condensate. An offset
using two 45º (degree) elbows will be required for plenum clearance
when the vent is increased to 3” (7.6 cm).

IMPORTANT

Accessory concentric vent / intake termination kits 1CT0302 and
1CT0303, and for Canadian applications 1CT0302-636 and
1CT0303-636 are available and approved for use with these fur-
naces. Horizontal sidewall vent terminations kits 1HT0901 &
1HT0902 are also approved for use with these furnaces.

 CAUTION

Solvent cements are flammable and must be used in well-ventilated
areas only. Keep them away from heat, sparks and open flames. Do
not breathe vapors and avoid contact with skin and eyes.

IMPORTANT

The vent must be installed with the minimum required clearances,
and must comply with local codes and requirements.
