Ruud AP13370-2 Blower Assembly Installation, Horizontal Vent Terminal Location

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

Soffit Vents

The location of the vent terminal depends on the following minimum clearances and considerations (see illustration):

	4'	4'
	(1,20m)	(1,20m)
Inside		4'
Corner
Electric		(1,20m)
Meter	18”		Fresh
	(45 cm)		Air
18” (45 cm)		4' (1,20m)	Intake
Window or Vent		3' above if within 10'
	4'	12" (30.5cm) (Above grade/snow level)
	(1,20m)

NOTICE: Canadian vent termination/location must follow CSA B149 requirements and may vary from above.

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.

Rising moisture will collect under eaves

Additional Considerations

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.

If soffit vent is too close, block off and install new vent at

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

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.

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.
