GENERAL
YORK Model DCG units are single package air conditioners
with gas heat designed for outdoor installation on a roof top or
a slab.
The units are completely assembled on rigid, permanently
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 aluminized steel tubular heat
exchangers and spark ignition with intermittent pilot.
This appliance is not to be used for temporary heating of
buildings or structures under construction.
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. Refer to Form 50.15-NM for additional information.
