YORK Model DHG units are single package air conditioners
with gas heat designed for outdoor installation on a rooftop or
a slab. The units are completely assembled on rigid, perma-
nently attached base rails. All piping, refrigerant charge, and
electrical wiring is factory-installed and tested. The units
require only electric power, gas piping and duct connections
at the point of installation. The gas-fired heaters have alumi-
nized steel tubular heat exchangers and spark ignition with
intermittent pilot. This appliance is not to be used for tempo-
rary heating of buildings or structures under construction.

the damage should be noted on the carrier's freight bill. Asep-
arate request for inspection by the carrier's agent should be
made in writing. Refer to Form 50.15-NM for additional infor-
mation.
