Inspection

As soon as you receive a unit, you must inspect
it for possible damage during transit. If damage
is evident, note the extent of the damage on the

CAUTION
This product must be installed in strict compliance
with the enclosed installation instructions and any
applicable local, state and national codes including,
but not limited to, building, electrical, and mechanical
codes.
The furnace and its individual shut-off valve must
be disconnected from the gas supply piping system
during any pressure testing at pressures in excess of
1/2 psig. Pressures greater than 1/2 psig will cause
gas valve damage resulting in a hazardous condition.
If it is subjected to a pressure greater than 1/2 psig,
the gas valve must be replaced.
The furnace must be isolated from the gas supply
piping system by closing its individual manual shut-
off valve during any pressure testing of the gas supply
piping system at test pressures equal to or less than
1/2 psig.
