General

UP Model DUQ units are dual fuel heat pump units designed for
outdoor installation. Only gas piping, electric power and duct
connections are required at the point of installation.
The 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.
