Make sure that all piping is properly braced. If the
venting will pass through an enclosed area, make sure
to leave at least one (1) inch (2.5 cm) clearance
around the piping for air circulation.

Through-the-Roof Venting Installation
Cut or drill a hole through the roof and ceiling, slightly
larger than the diameter of the vent pipe selected. The
larger hole will allow for final alignment with the water
heater. Extend a section of pipe through the hole in the
roof to the outside and attach the terminal assembly to
the exterior end of the pipe. Connect and secure all
piping and elbows from the power venter to the roof.
When the installation is completed, the vent terminal
must be a minimum of eighteen (18) inches (45.7 cm)
from the exterior surface of the roof (
see Figure 8
).
Make sure that all piping is properly braced. If the vent-
ing will pass through an enclosed area, make sure to
leave at least one (1) inch (2.5 cm) clearance around
the piping for air circulation.

DANGER
WARNING
CAUTION
AVERTISSEMENT
ATTENTION
ALWAYS
read and obey all safety messages printed
on the primer, cleaner, and cement containers.
Primer, cleaner, and cements are extremely flamma-
ble.
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 dam-
age, personal injury, or death.

1) Adjust the vent pipe length to properly fit the rubber
transition fitting on the blower assembly outlet.
2) Cut pipe ends squarely, removing all burrs and dirt.
3) Dry fit the pipe/fitting to be connected to make sure
they fit properly.
4) Clean the pipe/fitting with the proper primer or cleaner.
5) Apply a thin coat of cement to the fitting, avoiding
puddling inside.
6) Apply a liberal coat of cement to the vent pipe, leav-
ing no voids.
7) QUICKLY assemble parts while cement is fluid! If
you wait too long, re-coat pipe/fitting.
8) Push the vent pipe completely into the PVC or CPVC
coupling, turning as it goes until it bottoms out.
9) Hold pipe and fitting together for thirty (30) seconds.
Then carefully clean off any excess material with a
cloth. Allow connections a sufficient time to cure
before disturbing.
10) Loosen the upper hose clamp on the rubber transi-
tion fitting and fully insert the pipe of the vent system.
Do not apply cement to the rubber transition fitting.
11) Tighten the upper hose clamp to ensure the vent
pipe is firmly secured and gas tight.
12) Make sure that the lower hose clamp is firmly seated,
secured and gas tight. Gently move the vent pipe
side to side and vertically to ensure that it is securely
in place and that there is no slippage.

Follow the pipe manufacturer’s installation instructions in
order to install the vent pipe. Make sure to affix the pipe
sections together by using the item (fitting or hose clamp)
specified by the pipe manufacturer.
