Installing the water heater.

The water heater must be installed with the factory supplied blower assembly in place.

Venting

The water heater must be vented to the 

outdoors as described in these instructions. 

DO NOT connect this water heater to 

an existing vent or chimney - it must 

be vented separately from all other 

appliances.
NOTICE: This unit can be vented using 

only the following recommended pipe 

material. Use only 2- or 3-inch diameter 

pipe. 
PVC (Schedule 40, ASTM D1785)
CPVC (Schedule 40, ASTM F441)
ABS (Schedule 40, ASTM D2661)
ABS  (Schedule 40 DWV, Cellular Core, 

ASTM F891)

The fittings, other than the TERMINATION, 

should be equivalent to the following:
PVC (Schedule 40 DWV, ASTM D2665)
CPVC (Schedule 40, ASTM F438)
ABS (Schedule 40 DWV, ASTM D2661)
The unit may be vented horizontally 

through a wall or vertically through the 

roof.
Vent pipe runs must be adequately 

supported along both vertical and 

horizontal lengths. 
Maximum unsupported length is 

recommended to be no more than 6 feet.
It is imperative that the first hanger 

be located on the horizontal length 

immediately adjacent to the first  

90-degree elbow from the vertical rise of 

vent pipe connected to the water heater.

The support method used should isolate 

the vent pipe from floor joists or other 

structural members to help prevent the 

transmission of noise and vibration.
Do not support, pin or otherwise secure 

the venting system in a way that restricts 

the normal thermal expansion and 

contraction of the chosen venting material.
If the water heater is being installed as a 

replacement for an existing power vented 

water heater, a thorough inspection of 

the existing venting system must be 

performed prior to any installation work. 

  Verify that the correct materials as 

detailed above have been used, and 

that the minimum or maximum vent 

length and terminal locations as 

detailed in this manual have been 

met.

  Carefully inspect the entire venting 

system for any signs of cracks or 

fractures, particularly at the joints 

between elbows or other fittings and 

the straight length of vent pipe.

  Check the system for signs of sagging 

or other stresses in the 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 the 

installation and putting the water 

heater into service.

DANGER: Failure to 

install the blower assembly 

and properly vent the water 

heater to the outdoors as 

outlined in the Venting 

section of this manual will 

result in unsafe operation of 

the water heater causing 

bodily injury, explosion, 

fire or death. 
To avoid the risk of fire, 

explosion, or asphyxiation 

from carbon monoxide, 

NEVER operate the water 

heater unless it is properly 

vented and has adequate air 

supply for proper operation 

as outlined in the Venting 

section of this manual.
The vent pipe must overlap 

a minimum of ½” on each 

connection.  It is important 

that the vent pipe engages 

fully into any pipe fitting 

and be kept in that position 

until the adhesive has fully 

cured.  DO NOT drill or 

punch holes in the plastic 

pipe or fittings.
NOTICE: This unit is 

equipped with a Flammable 

Vapor Sensor.  Do not 

apply power until enough 

time has passed to allow the 

vapors from the primer and 

cement to dissipate.

Blower Assembly Installation 

(if not factory installed)

Connect blower assembly with the electrical connector. Attach 

Blower Assembly to top pan using the six (6) screws provided 

(See diagram to the left). Install rubber coupling (supplied in 

the box with water heater) on blower housing and secure it.

NOTICE:  The Blower Assembly is model specific and only 

the blower assembly supplied should be used on this water 

heater.
