SAFETY CONSIDERATIONS
Due to system pressure, moving parts and electrical
components, installation and servicing of air conditioning
equipment can be hazardous. Only qualified, trained, service
personnel should install, repair, maintain or service this
equipment.
Observe all precautions in the literature, on labels and tags
accompanying the equipment whenever working on air
conditioning equipment. Be sure to follow all other safety
precautions that apply.
Wear safety glasses and work gloves, and follow all safety
codes. Use a quenching cloth and have a fire extinguisher

GENERAL
YORK Model DCG units are single package gas-fired central
heating furnaces with cooling unit designed for outdoor
installation on a rooftop 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 electric
power, gas connection, duct connections, installation of
combustion air inlet hood, flue gas outlet hoods and fixed
outdoor air intake damper (units without economizer or
motorized damper option only) at the point of installation.
The gas-fired heaters have aluminized-steel tubular heat
exchangers and spark ignition with proven pilot.
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.
