General

®
YORK Affinity Model DNZ units are cooling/heating air
conditioners designed for outdoor installation. Only gas piping,
electric power and duct connections are required at the point of
installation.
The single or two stage gas-fired heaters have spark to pilot
ignition. The tubular heat exchangers are aluminized steel.
The refrigerant system is fully charged with R-410A Refrigerant,
and is tested and factory sealed.
