Inspection
As soon as a unit is received, it should be inspected
for possible damage during transit. If damage is
evident, the extent of the damage should be noted
on the carrier's freight bill. A separate request for
inspection by the carrier's agent should be made in
writing.
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
