SPECIFIC INSTALLATION INSTRUCTIONS
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.
Flat Base Mounting
1. Base may be mounted directly on the 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 the 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
dimension 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.
( Continue installation by following items #3 through
#5 in previous instructions for Flat Base.)
