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 mechani-
cal 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 sup-
ply piping system at test pressures equal to or less
than 1/2 PSIG.
