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