General - York ZF076 Installation Manual

General

YORK Model ZF units are either single package air conditioners
equipped with optional factory installed electric heaters, or
single package gas-fired central heating furnaces with cooling
unit. Both are designed for outdoor installation on a rooftop or
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 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. The units have 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 # 1NP0440. See Gas Heat
Application Data Table on page 13.
