Power Attic Ventilator

MODEL: RF-69NR, RF-68HRPSC

IMPORTANT:

For every 300 CFM of fan performance, a

minimum of one square foot of inlet space in attic or crawl
space is necessary for proper operation. Inlet areas should
be located as far from fan location as possible, such as in
the eave or side walls.

MOUNTING THE FAN

IMPORTANT:

If the fan will be mounted on a flat roof, make

a curb on which to mount the fan; the fan must be above
the level of the roof’s water line.
1. Determine location of fan (center of attic near roof peak).

At desired location, drill a hole through the roof (centered
between the rafters).

2. Using the drilled hole as a center, make a 14

circle on the roof. To make a circle, a compass can be
made of a scrap piece of wood with two nails placed 7

apart.

3. Make cutout in roof along the circle that has been made.

If the roof is shingled, cut shingles along the circle using
the tin snips, knife etc.

4. Place fan over opening in roof. Nail mounting flange to

roof. Caulk around mounting flange to help prevent water
seepage. If the roof is shingled, slide mounting flange
under the surrounding shingles.

MOUNTING THE THERMOSTAT'S OUTLET BOX

IMPORTANT: Do not mount outlet box near heat source.

1. Mount the outlet box to a nearby rafter so that the outlet

box is higher than the fan motor.
