AVERTISSEMENT
ATTENTION
ALWAYS read and abide by all safety messages printed on
the primer, cleaner, and cement containers. Primer, cleaner,
and cements are extremely flammable.
DO NOT store these
products near heat, sparks, or flames. They are harmful or
fatal, if swallowed. Their vapours are also harmful. They may
irritate eyes and can be absorbed through the skin. Failure
to follow these instructions can result in property damage,
personal injury, or death.

Primers, cleaners, solvents, and cements are available for
PVC and CPVC pipe/fittings. When cementing the pipe/fit-
tings, make sure to use only materials approved for the type
of pipe/fittings to be installed and in all cases, follow the vent
pipe/fittings manufacturers joining instructions. Never use
all-purpose cements, commercial glues, and adhesives to join
PVC or CPVC pipe/fittings.
1) Cut pipe ends squarely, removing all burrs and dirt.
2) Dry fit the pipe/fitting to be connected to make sure they fit
properly.
3) Clean the pipe/fitting with the proper primer or cleaner.
4) Apply a thin coat of cement to the fitting, avoiding puddling
inside.
5) Apply a liberal coat of cement to the vent pipe, leaving no
voids.
6) QUICKLY assemble parts while cement is fluid! If you
wait too long, re-coat pipe/fitting.
7) Push the vent pipe completely into the coupling, turning as
it goes until it bottoms out.
8) Hold pipe and fitting together for thirty (30) seconds. Then
carefully clean off any excess material with a cloth. Allow con-
nections a sufficient time to cure before disturbing.
9) Remember that vent pipes must be adequately and
securely suppported.

Two (2) 90-degree PVC elbows are supplied with the water
heater and shall be installed at the end of the vent and
air intake piping to serve as the termination for through-
the-wall installation when the vent system is built with
PVC pipes. If CPVC is used to build the vent system, use
90-degree CPVC elbows that are approved to be used with
the vent system. A wire mesh screen must be installed in
the termination elbows.

elbow and insert it into the polypropylene elbow. Push the
screen until it locks in place inside the elbow.

DANGER
WARNING
CAUTION
AVERTISSEMENT
ATTENTION
In freezing weather, check for snow accumulation around
the water heater vent and air intake terminals where they
pass through the outside wall. The open ends of the termi-
nals must be installed at least twelve (12) inches (30 cm)
above the highest anticipated snowfall to prevent blockage
by snow.

WARNING
CAUTION
AVERTISSEMENT
ATTENTION
Check that all openings and gaps in the outside wall near
and around where the vent and air intake pipes pass
through the exterior wall are sealed to prevent infiltration
of combustion products into the building.
