10.7 - PVC/CPVC
vent piping
materials
WARNING!!!
Use only
the materials listed in Tables
10-1 and 10-2 for vent pipe,
and fi ttings. DO NOT mix vent
systems of different types or
manufacturers, unless listed in
this manual. Failure to comply
could result in severe personal
injury, death, or substantial
property damage.
WARNING!!!
This appliance
requires a special venting
system. The fi eld provided vent
fi ttings must be connected to
the boiler following Section
10.7.1. Use only the vent
materials, primer, and cement
specifi ed in this manual to make
the vent connections. Failure to
follow this warning could result
in fi re, personal injury, or death.
WARNING!!!
Do not
insulate PVC/CPVC exhaust
pipe nor install into an
enclosure or any other
obstruction thereby preventing
the cooling of the exhaust pipe.
Failure to follow this warning
could result in excessive levels
of carbon monoxide or a fi re,
which can result in severe
personal injury or death!
WARNING!!!
Improper
installation of PVC or CPVC
systems may result in injury or
death.
NOTICE Installation must comply
with local requirements and with the
National Fuel Gas Code, ANSI Z223.1
for U.S. installations or CSA B149.1 for
Canadian installations.
NOTICE The installer must use a
specifi c vent starter adapter at the
fl ue collar connection, supplied by the
vent manufacturer to adapt to its vent
system. See Table 10-2 for approved
vent adapters.
For installation in Canada, vent pipe
system must be certifi ed to ULC-S636
(see Table 10-1).
NOTICE All vent pipes must be glued,
properly supported, and the exhaust
must be pitched a minimum of a 1/4
inch per foot back to the boiler (to allow
drainage of condensate).
NOTICE Installation of a PVC/CPVC
vent system should adhere to the PVC/
CPVC vent manufacturer’s installation
instructions supplied with the vent
system.
NOTICE The installer must use a
specifi c vent starter adapter at the
fl ue collar connection, supplied by the
vent manufacturer to adapt to its vent
system. See Table 10-2 for approved
vent adapters.
10.7.1 - Installing PVC/
CPVC vent and air piping
NOTICE Use only cleaners, primers,
and solvents that are approved
for the materials which are joined
together.
1. Work from the boiler to vent or air
termination. Do not exceed the
lengths given in Section 10-4.
2. Cut pipe to the required lengths and
deburr the inside and outside of the
pipe ends.
3. Bevel outside of each pipe end to
ensure even cement distribution
when joining.
4. Clean all pipe ends and fi ttings using
a clean dry rag (Moisture will retard
curing and dirt or grease will prevent
adhesion).
5. Dry fi t vent or air piping to ensure
proper fi t up before assembling any
joint. The pipe should go a third to
two-thirds into the fi tting to ensure
proper sealing after cement is
applied.
6. Priming and Cementing:
a. Handle fi ttings and pipes carefully
to prevent contamination of
surfaces.
b. Apply a liberal even coat of primer
10 - INSTALLATION - Vent and combustion air
to the fi tting socket.
c. Apply a liberal even coat of primer
to the pipe end to approximately
1/2” beyond the socket depth.
d. Apply a second primer coat to the
fi tting socket.
e. While primer is still wet, apply an
even coat of approved cement to
the pipe equal to the depth of the
fi tting socket.
f. While primer is still wet, apply an
even coat of approved cement to
the fi tting socket.
g. Apply a second coat of cement to
the pipe.
h. While the cement is still wet,
insert the pipe into the fi tting, if
possible twist the pipe a 1/4 turn
as you insert it. NOTE: If voids
are present, suffi cient cement
was not applied and joint could be
defective.
i. Wipe excess cement from the joint
removing ring or beads as it will
needlessly soften the pipe.
10.7.2 - PVC/CPVC air
intake/vent connections
Combustion Air Intake
connection (see Figure 10-8
Item “C”).
This connection is used
to provide combustion air directly to
the boiler from outdoors. Combustion
air piping must be supported per
guidelines listed in the National
Mechanical Code, Section 305, Table
305.4 or as local codes dictate.
To connect a PVC/CPVC pipe to the
air intake connection proceed as follow
while referring to Figure 10-8:
1. install boiler adapter “A” above
boiler. Rotate boiler adapter “A” so
as air intake and vent connections
are in the desired left or right side.
Check stamped arrow to understand
which is the vent and air intake
connection.
WARNING!!!
Check
stamped arrow on boiler adapter
for the correct side of air intake.
Failure to follow this warning
could result in excessive levels
of carbon monoxide or a fi re,
which can result in severe
personal injury or death!
