Installing the Water Heater:
Blower Assembly Installation
Connect blower assembly with Molex connector.
Attach Blower Assembly to top pan using the five
screws (see diagram to the left).
Install rubber coupling (supplied in the box with
water heater) on blower housing and secure it.
Horizontal Vent Terminal Location
The location of the vent terminal depends on the
following minimum clearances and considerations (see
illustration):
Twelve (12) inches (30.5cm) above grade level and
above normal snow levels.
Four (4) feet (1.2m)
2
below, or four (4) feet (1.2m)
horizontally from any door, operable window, soffit,
under eave vent or gravity air inlet to the building or
other appliances, or from gas or electric meters. Do
not locate vent above walkways, doors, windows, air
inlets, gas or electric meters or other equipment.
Three (3) feet (0.9m) above any forced air inlet lo-
cated within 10 feet (3,05m)³ of any fresh or make-
up air inlet such as for a dryer or furnace area is
considered to be a forced air inlet.
Eighteen (18) inches (45cm) from an inside corner
formed by two exterior walls, overhang, or
obstruction.
Additional Considerations
If soffit vent is too
close, block off and
install new vent at
another location

WARNING
: Moisture in the flue gas will condense as it
leaves the vent terminal. In cold weather this condensate can
freeze on the exterior wall, under the eaves and on surrounding
objects. Some discoloration to the exterior of the building is to
be expected. However, improper location or installation can
result in severe damage to the structure or exterior finish of the
building.
Do Not install vent terminal under any patio or deck.
To help prevent moisture from freezing on walls and
under eaves, do not locate vent terminal on the side of
a building with prevailing winter winds.
Do Not terminate vent pipe directly on brick or
masonry surfaces. It is recommended to use a rust-
resistant sheet metal backing plate 2 x 2 feet
(60cm x 60cm) behind vent. (See illustration.)
Do Not locate vent terminal too close to shrubbery, as
flue gasses may damage them.
Caulk all cracks, seams and joints within six (6) feet
(1,80m) of vent terminal.
All painted surfaces should be primed to lessen the
chance of physical damage. Painted surfaces will
require maintenance.
Insulate vent pipe exposed to cold conditions (attics,
crawl spaces, etc.) with inflammable material to help
prevent moisture from accumulating in vent pipe.
Do Not extend exposed vent pipe outside of building.
NOTICE: Canadian vent termination/location must
follow CSA B149 requirements and may vary from above.
