8.7 - PVC/CPVC
vent piping
materials
WARNING!!! Use only the
materials listed in Tables 4 and 5
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 8.7.1. 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, closet, alcove
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 5 for approved
vent adapters.
For installation in Canada, vent pipe
system must be certifi ed to ULC-S636
(see Table 4).
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 5 for approved
vent adapters.
8.7.1 - 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 8.3.
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 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.
8.7.2 - PVC/CPVC air
intake/vent connections
Combustion Air Intake
connection (see Figure 29 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 29:
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!
2. insert the clamp “D” into convertor
“A” in the “C” side.
3. insert the adapter “E” into
connection “C” of the convertor
“A”;
