Installation Instructions
Flat Base Mounting
1. Base may be mounted directly on deck beneath roof shingles or
upper edge of base plate may be slid underneath shingles.
2. Securely screw or bolt base plate to roof through the four corner
mounting points.
3. Through the opening, attach ductwork to fan inlet orifice by using
Fantech FC clamps or duct tape.
4. Refer to wiring diagram in this guide to complete electrical connections.
5. Once secured and wired, generously apply tar or other sealant
around edges of base to prevent leakage. Be sure to replace any
lifted shingles.
Curb Mounting
1. Outside dimensions of flanged curb should be approximately 3/8"
smaller than the outside dimensions of base. Flanged curbs are
available from Fantech.
2. Center curb around roof opening and securely attach to roof. It is
advisable to put a bead of sealant around the inside edge of curb.
3. Before mounting base on curb, place a layer of sealant along the
top edge of the curb.
4. Place unit on curb and securely attach with bolts or screws.
5. Through the opening, attach ductwork to fan inlet orifice by using
Fantech FC clamps or duct tape.
6. Refer to wiring diagram in this guide to complete electrical connections.
7. Once secured and wired, generously apply tar or other sealant
around edges of base to prevent leakage. Be sure to replace any
lifted shingles.
Suitable sealing such as tar or similar material (not included) should be used to prevent leakage. To prepare for installation, determine the size
and type of ducting, if any, to be used. Make an opening in the roof just large enough to accommodate ducting and electrical supply.
