manufacturer. Follow the manufacturer’s instructions in
the use of primer and cement and never use primer or
cement beyond its expiration date.
All fire stop and roof flashing used with this system must
be UL listed material.
Acceptability under Canadian standard CAN/CSA B149
requires full compliance with all installation instructions.
The
authority
having
jurisdiction
(gas
inspection
authority, municipal building department, fire department,
etc.) should be consulted before installation to determine
the need to obtain a permit.
8.5
MATERIAL
USA:
Combustion air and vent pipe, fittings, primers, and
solvents must conform to American National Standards
Institute (ANSI) standards and American Society for
Testing and Materials (ASTM) standards.
CANADA:
Vent pipe installations in Canada must conform to
the requirements of CAN/CSA B149 code.
PVC and
CPVC vent systems must be composed of pipe, fittings,
cements, and primers listed to ULC S636. Combustion
air pipe can use ABS material meeting the ASTM
standard D2661 / CSA B181.1.
All vent piping and combustion air piping MUST conform
to local and national codes.
8.6
SIZE DE VENT AND
COMBUSTION AIR PIPES
Furnace combustion air and vent pipe connections are
sized for 2” pipe.
The maximum allowable vent length for the vent and
combustion air pipe (when used) is listed in table 10
and depends on the furnace input. The maximum length
must include straight pipe and any fitting and termination.
Equivalent length of various fitting is list in table 11.
A minimum linear length of 5 ft must be respected.
To properly measure the Equivalent Vent Length :
1. Measure the linear pipe distance from the furnace
to the termination for each pipe.
2. Count the number of elbows for each pipe.
3. For each pipe, multiply the number of elbows by the
equivalent length for the type of elbow used (see
table 11). Record the equivalent length of all the
elbows for each pipe.
4. Record the equivalent length of the termination
used (see table 11 ).
5. Add the equivalent length of the elbows and
termination to the linear distance measured for
each pipe.
6. If the calculated vent length is greater than the
maximum allowed vent length (for either vent pipe
or combustion air pipe), consider modifying the
termination location.

CONNECTING TO FURNACE
Never common vent with any other appliance. Do not
install in the same chase or chimney as a metal or high
temperature plastic pipe from another gas or fuel-burning
appliance unless the required minimum clearances to
combustibles are maintained between the approved PVC
pipe and the other pipes. Clean and deburr all pipe cuts.
In the included parts bag, an exhaust venting gasket is
supplied and needs to be installed on the exhaust of the
top panel.
For proper installation of venting/exhaust pipe:
1. Position the supplied venting gasket on the top
panel exhaust.
2. Slowly slide a 2" diameter pipe throught the venting
gasket. This step will be easier if pipe is chamfered
and using a soap solution.
3. Position this venting pipe length on the rubber vent
collector and tighten the collar.
4. Install the remaining vent pipes. It is recommended
that all pipes be cut, prepared, and preassembled
before permanently cementing any joint.
5. Working from furnace to outside, cut the pipe to the
required length(s).
