FAN INSTALLATION

STEP 1.

When selecting the fan mounting location, the following criteria should be considered: a) type of application; b) proximity

to fresh air intakes; c) sound created by fan operation.

a) For dryer boosting applications, fan must be mounted a minimum of 12 linear feet from the dryer outlet. If the

fan is mounted closer than the recommended 12 feet, it will develop enough pressure to pull wet lint through the

duct system causing buildup on the impeller and clogging of the vents in the discharge cover. Important Notice:

To prevent the possibility of fire hazards when using a booster fan in conjunction with a gas fired dryer, booster

fan flow must not exceed the dryer fan capacity. Typical residential dryer fans produce 160 cfm.

For range venting applications, sufficient access for periodic cleaning of exhausted grease from the wall and fan

discharge cover should be provided. NOTE: In order to minimize operational noise, only the RVF4 should

be used for a direct through-the-wall system. The larger units (RVF4XL - RVF8XL) should only be used in

conjunction with ducted systems.

b) With any exhaust system, fan should be located a minimum of 6 feet horizontally and 8 feet vertically from any

fresh air intakes for HVAC systems, heat recovery systems, etc. to prevent re-entrainment of exhausted air

streams. Windows that are frequently opened during moderate seasons may also be considered fresh air intakes.

c) Although system noise at the point of exhaust will be virtually silent, windows and other structural openings

may be sources for noise entry during fan operation. Proximity to windows and openings should be considered.

Select the location on the exterior wall where the fan is to be mounted. Make a hole through the wall that is l/2"

larger than the diameter of the fan duct connection collar. A short piece of rigid duct (not included) approximately

2" longer than the wall thickness is recommended for use as an extension through the wall.

STEP 2.

Remove the four screws securing the white fan discharge cover and remove the cover. Place the fan against the

wall, as centered as possible on the wall opening, then mark the location of the four backplate mounting holes and

the electrical knockout. Drill a hole for the electrical service that is ¹ ₂" larger than the size of conduit to be used. A

1" diameter electrical service opening is provided on the fan backplate (see dimensional drawing on Page 2).

When mounting the fan on a masonry wall, drill ⁷ ₃₂" holes for the four anchors and mounting screws (provided).

Tap the anchors flush into the holes. When mounting the fan on a wood surface, wood screws should be used.

Note: If the fan is to be mounted on a wall surface which is Lapped Siding, a mounting frame made from 1 x 1

board may be necessary fora flush fit (see Illustration #2).

STEP 3.

Before mounting the fan, bring the electrical supply through the wall. Attach the extension collar to the fan duct

connection collar. The connection should be as air tight as possible to prevent leakage from the wall cavity. Apply

a generous amount of polyurethane caulk to the exterior side of the fan housing backplate. This will ensure an

airtight, waterproof connection between the fan and the wall surface. If a mounting frame is used in conjunction

with lapped siding, be certain to apply a generous amount of caulk between the frame and the wall as well as the

fan backplate and the frame. Mount the fan to the wall.

Note: Se certain to make an airtight seal around all interior wall penetrations before attaching duct work.

FINAL INSTALLATION NOTE:

If the fan is being mounted in a location other than under an eve or protected by an eve, it is highly recommended

that a standard flashing be installed and sealed against the wall and upper edge of the fan discharge cover to

prevent rain water running down the wall surface from entering the fan housing (see Illustration #1).

DUCTING HINTS

a) Whenever the duct passes through an unconditioned space, it is recommended that insulated ducting be

used. This will prevent the possibility of condensation from building up both within the duct and on the

exterior duct wall, particularly when the fan is used as bathroom exhaust where high levels of moisture in the

air stream is common.

b) Insulated flexible duct, as used for take-offs in residential heating and air conditioning systems is recommended.

Since the fans are capable of overcoming higher resistance created by long duct runs and flexible duct work,

the system will not see an appreciable loss of performance. However, when using flexible duct, it should be

stretched as straight and tight as possible to minimize losses.

c) When connecting ductwork to the fan, grilles, or transitional devices, make as airtight a connection as possible

to prevent leakage of moisture, odors or other contaminants which are being exhausted.
