GENERAL

YORK Model DR units are either single package cool-
ing units equipped with optional factory installed elec-
tric heaters, or single package gas-fired central heating
furnaces with cooling unit. Both are designed for out-
door installation on a rooftop or 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 electric power, gas connec-
tion, 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 supplemental electric heaters have nickel-chrome
elements and utilize single point power connection.
The gas-fired heaters have aluminized-steel or optional
stainless steel, tubular heat exchangers with spark
ignition with proven pilot. All gas heaters are shipped
from the factory equipped for natural gas use, but can
be field converted to L.P./Propane with Kit Model #
1NP0418.
