INSTALLATION INSTRUCTIONS

Power Attic Ventilator

MODEL: RF-49NR, RF-59NRPSC, RF-85R

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

1

⁄2” diameter

circle on the roof. To make a circle, a compass can be

made of a scrap piece of wood with two nails placed 7

1

⁄4”

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.
