! WARNING:
Any attempt to operate furnace before
replacing transit-mode weather cap
with upper roof jack section may re-
sult in hazard of fire, explosion or as-
phyxiation.
Power supply circuit to the furnace must be

National Electrical code (ANSI-C1/NFPA-70),
or Canadian Electric Code Part 1 (CSA 22-1)
and all local codes having jurisdiction.
