The gas/electric units naturally derate with altitude. Do not attempt to increase the firing rate by changing orifices or increasing the manifold pressure. This can cause poor combustion and equipment failure.

Page 13: Condensate Drain
HEAT PUMP OPERATION Heating Cycle The heat pump operates in the heating cycle by redirecting refrigerant flow through the refrigerant circuit external to the compressor. This is accomplished through the reversing valve. Hot discharge vapor from the compressor is directed to the indoor coil (evaporator on the cooling cycle) where the heat is removed, and the vapor condenses to liquid. -
Page 14: Heat Pump Mode Operation Sequence Of Operation
Outdoor Thermostat For optimal performance, a dual fuel thermostat with an outdoor temperature sensor should be used. TSTATGTS3275 (Emerson Dual Fuel thermostat) with TSTATTSORS (outdoor temperature sensor) is recommended. This will allow the installer to control when the unit switches from heat pump to gas heat based on a set point entered into the thermostat. -
