materials
WARNING!!!
Use only
the materials listed in Figures
11-7 and 11-8 for vent pipe,
and fittings. DO NOT mix vent
systems of different types or
manufacturers, unless listed in
this manual. Failure to comply

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 cover
with thermal insulation 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
result in severe personal injury
or death!
WARNING!!!
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!!!
pipes must be glued, properly
supported, and the exhaust
must be pitched a minimum of
a 1/4 inch per foot back to the
appliance (to allow drainage of

11.6.1 - 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 appliance to vent or
air termination. Do not exceed the
lengths given in Section 11.3;
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
Improper
retard curing and dirt or grease will
prevent adhesion);
Connection of the the vent or air
piping to the appliance adapters
5.- Dry fit vent or air piping to ensure
proper fit up before assembling
pipes to the appliance adapters. The
pipe should go completely into the
adapter to ensure proper sealing
after sealant is applied.
