DANGER
This product contains one or more chemical s known to the State
of California to cause cancer, birth defects, or reproductive harm.
Sacrificial anodes are used to extend tank life. Anode removal, except for
inspection and/or r eplacem ent, will nullif y the warrant y. In ar eas where water is
unusually active, an odor may occur at the hot water fauc et due to a reaction
between the sacrificial anodes and the impurities in the water. If this should
happen, alternative anodes may be purc hased from the supplier that installed
this water heater. This will minimize the odor while protecting the tank.
Additionally, the water hea ter should be flushed with appropr iate dissolvers to

Venting System Condensation
Condensate formation will occur in the venting of this condensing power vent
water heater. In order to effectively drain the condensate from the venting,
tubing has been installed on a factory supplied exhaust adapter with drain
outlet mounts on the blower. The tubing will drain any accumulated
condensate from the venting system.
1. In a horizontal application, it is important that condensate not be
allowed to buildup in the exhaust vent pipe. To prevent this from
happening, the pipe should be installed with a slight upward slope of ¼
inch (.6 cm) per foot (.3 m). The vent system must be supported every
5 feet (1.5 m) of vertical run and every 3 feet (.9 m) of horizontal run of
vent pipe length.
This water heater is a condensing power vented appliance and is designed to
vent its products of combustion through 2” (5.1 cm), 3” (7.6 cm) or 4” (10.2 cm)
diameter vent pipe to the outdoors. This water heater may be either vented
horizontally through the wall or vertically through the roof. Use a 2” (5.1 cm) to
3” (7.6 cm) reducer to connect to the vent outlet when using 3” (7.6 cm) vent
pipe or 2” (5.1 cm) to 4” (10.2 cm) reducer to connect to the vent outlet when
using 4” (10.2 cm) vent pi p e. Apply the proper cement at the joint locations.
Table 1 lists the maximum vent lengths for this water heater using 2” (5.1 cm)
vent pipe. If possible, locate the water heater so that the venting length and
number of elbows are kept to the minimum distance necessary to reach the
outside. If the installation requires venting lengths that exceed the lengths
listed for 2” (5.1 cm) vent pipe in Table 1, then use 3” (7.6 cm) vent pipe for the
vent connector or 4” (10.2 cm) as necessary.
Table 2 lists the venting distances allowed with 3” (7.6 cm) diameter vent pipe.
When venting with 3” (7.6 cm) vent pipe, use a 3” (7.6 cm) to 2” (5.1 cm)
reducer to exit through the building wall with 2” (5.1 cm) vent pipe. Use the 2”
(5.1 cm) vent terminal supplied with the water heater to terminate on the
outside of the building. If the length of 2” (5.1 cm) vent pipe needed to go
through the wall is greater than 14” (35.5 cm), use 3” (7.6 cm) to go through the
wall and reduce to 2” (5.1 cm) vent pipe immediately after exiting the outside
wall. Refer to the venting illustrations on the following pages. Make sure the
vent pipe terminal elbow fitting is at least 1” (2.5 cm) away from the edge of the
wall.
Table 3 lists the venting distances allowed with 4” (10.2 cm) diameter vent pipe.
When venting with 4” (10.2 cm) vent pipe, use a 4” (10.2 cm) to 2” (5.1 cm)
reducer to exit through the building wall with 2” (5.1 cm) vent pipe. Use the 2”
(5.1 cm) vent terminal supplied with the water heater to terminate on the
outside of the building. If the length of 2” (5.1 cm) vent pipe needed to go
through the wall is greater than 14” (35.5 cm), use 4” (10.2 cm) to go through
the wall and reduce to 2” (5.1 cm) vent pipe imm ediatel y after exit ing th e
outside wall. Refer to the venting illustrations on the following pages. Make
sure the vent pipe terminal elbow fitting is at least 1” (2.5 cm) away from the
edge of the wall.
