12.6 - PVC/CPVC
vent piping
materials
WARNING!!!
Use only
the materials listed in Figures
12-7 and 12-8 for vent pipe,
and fittings. 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 vent pipe
must be connected to the
heater following Section 12.6.1.
Use only the vent materials,
primer, and cement specified
in this manual to make the vent
connections. Failure to follow
this warning could result in fire,
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 fire, which can
cause severe personal injury or
death!
WARNING!!!
Improper
installation of PVC or CPVC
systems may result in excessive
levels of carbon monoxide or
a fire, which can cause severe
personal injury or death!
WARNING!!!
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
heater (to allow drainage of
condensate). Failure to follow
this warning could result in
excessive levels of carbon
monoxide or a fire, which can
result in severe personal 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.
For installation in Canada, vent pipe
system must be certified to ULC-S636
(see Figures 12-7).
NOTICE! Installation of a PVC/CPVC
vent system should adhere to the PVC/
CPVC vent manufacturer’s installation
instructions supplied with the vent
system.
12.6.1 - 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 heater to vent or
air termination. Do not exceed the
lengths given in Section 12.3.
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 fittings using
a clean dry rag (Moisture will retard
curing and dirt or grease will prevent
adhesion).
Connection of the the vent or air
piping to the heater adapters
5. Dry fit vent or air piping to ensure
proper fit up before assembling
pipes to the heater adapters. The
pipe should go completely into the
adapter to ensure proper sealing
after sealant is applied.
a. Handle adapters and pipes
carefully to prevent contamination
of surfaces.
12 - INSTALLATION - CATEGORY IV: Vent and combustion air
b. Apply a liberal even coat of
VITON-BASED RTV high
temperature silicone (or
equivalent) to the the pipe end
approximately 1/2” beyond the
socket depth.
c. While the VITON-BASED RTV
high temperature silicone is still
wet, insert the pipe into the heater
adapter. NOTICE! If voids are
present, sufficient VITON-BASED
RTV was not applied and joint
could be defective.
d. Tight the clamp to mechanically
secure the joint
Connection between pipes and /or
elbows and/or terminals of the the
vent or air piping
6. Dry fit vent or air piping to ensure
proper fit up before assembling any
joint. The pipe should go a third to
two-thirds into the fitting to ensure
proper sealing after cement is
applied.
7. Priming and Cementing:
a. Handle fittings and pipes carefully
to prevent contamination of
surfaces.
b. Apply a liberal even coat of primer
to the fitting 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
fitting socket.
e. While primer is still wet, apply an
even coat of approved cement to
the pipe equal to the depth of the
fitting socket.
f. While primer is still wet, apply an
even coat of approved cement to
the fitting socket.
g. Apply a second coat of cement to
the pipe.
h. While the cement is still wet,
insert the pipe into the fitting, if
possible twist the pipe a 1/4 turn
as you insert it.
NOTICE!
If voids
are present, sufficient 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.
