Instructions / Assembly

• DO NOT terminate near soffit vents or crawl space or other area where condensate or vapor could create a nuisance

hazard or cause property damage.

• DO NOT locate the exhaust vent terminal where condensate or vapor could cause damage or could be detrimental to the

operation of regulators, relief valves, or other equipment.

• DO NOT locate the exhaust vent terminal over public area or walkways where condensate or vapor can cause nui sance or

hazard.

• DO NOT locate the vent terminal in proximity to plants/shrubs.

INSTALLATION

VENT INSTALLATION – Before proceeding, make certain

you understand the procedure and cautions covered in the

section “Joining Pipes and Fittings.”

POWER VENT INSTALLATION – Power venting is where

the indoor air is used and the exhaust is vented to the

outside. Venting may be run horizontally through an

outside wall or vertically through a roof through using

either 2" (5.1 cm), 3" (7.6 cm), 4" (10.2 cm) diameter

PVC, ABS or CPVC. This water heater is supplied with a

screened intake elbow and exhaust coupling referred to

as the air intake terminal and the exhaust vent terminal.

NOTE: Flexible PP vent kit is available for Power Vent

configurations, in 2" and 3" diameters. These kits should

be used for vertical venting only.

NOTICE:

Use of PVC cellular core (ASTM-F891), ABS Schedule

40, DWV cellular core (ASTM –F628), or Radel®

(polyphenylsulfone) in non-metallic venting systems is

prohibited.

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” per foot. The vent

system must be supported every 5 feet of vertical run and

every 3 feet of horizontal run of vent pipe length.

Failure to properly support the vent piping with hangers

and clamps may result in damage to the water heater or

venting system.
