PVC terminal is removed and inserted into the new
fi tting.
This water heater is supplied with a 45 degree
termination elbow that is a special fi tting that must be
used with the appliance.
PVC Materials should use ASTM D-2564 Grade
Cement; CPVC Materials should use ASTM F-493
Grade Cement and ABS Materials should use ASTM
D-2235 Grade Cement.
If the water heater is being installed as a replacement
for an existing power vented heater in pre-existing
venting, a thorough inspection of existing venting
system must be performed prior to any installation work.
Verify that correct material as detailed above has been
used, and that the minimum or maximum vent lengths
and terminal location as detailed in this manual have
been met. Carefully inspect the entire venting system
for any signs of cracks or fractures, particularly at joints
between elbows and other fi ttings and straight runs of
vent pipe. Check system for signs of sagging or other
stresses in joints as a result of misalignment of any
components in the system. If any of these conditions
are found, they must be corrected in accordance
with the venting instructions in this manual before
completing installation and putting the water heater
into service.
NOTE:
(A.) For water heaters in locations with high
ambient temperatures (above 100°F (38°C)) it is
recommended that CPVC or ABS pipe and fi ttings be
used. (B.) A 22.5 degree elbow (2 in. vent pipe) or a 45
degree elbow (3 in. vent pipe) with an installed screen
VENT TERMINAL must be used in all cases.
4. There will be some installations where condensate will
be formed in the horizontal runs of the vent system.
This condensate will run into the condensate trap. The
water heater is shipped with a condensate tube that
attaches to the condensate trap. No other tee or fi tting
is required. Refer to the section titled “Condensate”.
INSTALLATION OF VENT SYSTEM
Before beginning installation of piping system thoroughly
read the “Vent Pipe Preparation” section of this manual.
If you are installing your system so that it vents through
roof, please refer to the section titled “Installation Of
Vertical Vent System”.
Ensure the vent length is long enough that the outside air
will not cause the water heater to freeze.
VENT TERMINAL INSTALLATION, SIDEWALL
Vent terminals supplied with heater must be used.
CAUTION
NOTE:
BEFORE BEGINNING INSTALLATION OF ANY
VENT PIPE READ THE VENT PIPE MANUFACTURER’S
INSTALLATION INSTRUCTIONS.
1. After the points of termination have been determined,
install the vent terminal by using the cover plate as
a template to mark the hole for the vent pipe to pass
through the wall. BEWARE OF CONCEALED WIRING
AND PIPING INSIDE THE WALL.
2. If the Vent Terminal is being installed on the outside
of a fi nished wall, it may be easier to mark both the
inside and outside wall. Align the holes by drilling
a hole through the center of the template from the
inside through to the outside. The template can now
be positioned on the outside wall using the drilled hole
as a centering point for the template.
3. A) MASONRY SIDEWALLS
Chisel an opening approximately 1/2 in. (1.3cm)
larger than the marked circle.
B) WOODEN SIDEWALLS
Drill a pilot hole approximately 1/4 in. (0.64cm)
outside of the marked circle. This pilot hole is used
as a starting point for a saws-all or sabre saw blade.
Cut around the marked circle staying approximately
1/4 in. (0.64cm) outside of the line. (This will allow
the vent to easily slide through the opening. The
resulting gap will be covered up by the Vent Terminal
cover plate.) Repeat this step on inside wall if
necessary.
4. Cut a length of vent pipe about 3.5 in. (9cm) longer
than the wall thickness at the opening.
5 Glue the vent terminal to the section of the pipe.
6. Slide the wall plate over pipe to stop against the vent
terminal.
7. Place a bead of caulking (not supplied) around the
gap between the pipe and the wall. Place some of the
caulking on the back of the plate to hold it against the
wall after installation.
8. If the vent pipe is installed up to the wall, with a coupling
on the end against the wall opening, the pipe with
the vent terminal can be prepared for gluing before
inserting through the wall. Slide the pipe through the
wall and insert into coupling on the other side of the
wall, making sure that the vent terminal ends up pointed
in the correct position (see Figure 22).
