GENERAL

YORK Model DM units are either single package air conditions 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.

These 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. See Gas Heat Application Data Table.
