Flat roof installations
1. Locate the 11" diameter hole between rafters.
2. Build a sloping base or roof curb that will mount the remote blower at a
minimum pitch of 2 - 1/2". (See FIGURE 5 and 6)
3. Weatherproof the base as required with proper sealant.
4. Locate the base so that the remote blower’s vent aligns with the 11" diameter
hole and the blower sits evenly on the base with no gaps.
Note: Make sure that the discharge end of the remote blower faces away from the
direction of prevailing winds. (FIGURE 7)
5. Use dimensions from either FIGURE 2 or 3 to locate the 1-1/4"
diameter wiring hole.
