INSTALLATION INSTRUCTIONS
Plan installation carefully. Roof cap will accept 3” or 4” round duct. Tape all joints with duct tape to prevent air and water leaks.
NOTE : DO NOT INSTALL THE ROOF CAP ON A FLAT ROOF.
-
Cut a 5” diameter hole through roof boards and shingles
-
Connect 4” metal duct connector to opening in bottom of roof cap:
-
Insert one edge of “V cut” under edge of “Notch.”
-
Rotate duct connector 360 degrees to completely engage.
-
Insert duct connector/roof cap assembly into hole in roof.
-
Trace outline of roof flange onto shingles.
-
Trim shingles as shown, so they will fit snugly around hood of roof cap when installed. Seal all around duct with roof cement.
-
Slide 4” hose clamp over end of flexible hose and attach hose to connector. Tighten clamp securely.
-
Insert hose and connector into hole in roof.
-
Carefully lift shingles and slide back flange of roof cap under shingles. Nail flange to roof under shingles at top and two sides. Nail directly to roof at bottom.
-
Use roof cement to seal shingles to top and sides of roof cap. Seal all nail heads with roof cement as well.
NOTE : Use as short a duct run as possible, for best fan performance. If the 8-foot length is more than needed, cut hose to desired length. -
Slide hose clamp over free end of hose and fasten hose to fan discharge collar.
NOTE : If discharge collar on fan is 3” diameter, use the neoprene strip to increase the diameter to 4”
To install the neoprene strip
- Center it on the top of the discharge collar.
- Remove the paper backing.
- Smoothly wrap it around the discharge collar so that the pressure-sensitive adhesive holds it in place.
