C. Wiring Requirements
1. Route a copper, with ground, 120 Vac supply
wire from the time delay fuse or circuit breaker
box to the roof opening. Use a listed/certied
non metallic - sheathed single strand cable. See
"A. Table - Unit Data" on page (4).
If vent fan was removed, the existing wire
may be used provided it is of proper type,
size, location, and correctly fused.
a. This supply wire must be located in the front
portion of the roof opening.
b. The power MUST be on an appropriately
sized separate time delay fuse or circuit
breaker. See "A. Table - Unit Data" on page
(4).
c. Make sure that at least 15″ of supply wire
extends into the roof opening. This ensures
an easy connection at the junction box.
d. Protect the wire where it passes into the
opening with approved method.
