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.
