Goodman 80,000 BTU 80% AFUE Upflow/Horizontal Gas Furnace Model GMH80803BN
The Goodman GMH80803BN 80,000 BTU 80% AFUE with a money saving multi-speed blower, two-stage gas valve, multi position upflow furnaces features the latest Dual $aver technology, a long lasting Silicon Nitride ignition system and a patented aluminized tubular heat exchanger. Moreover, the furnaces are trial tested in the industry for heating and heating/cooling system combinations.
These furnaces are specifically designed to be used along with a single stage room thermostat. The 80,000 BTU 80% Upflow furnaces include the provision to be operated in different heating modes ranging from the two stage burner low- stage to the higher stage depending on the adjustable time pre-set on the board. The time, is however, not controlled by the thermostat. The blower has two different speeds in heating mode, low and high, and it changes speed accordingly based on the stage in which it’s operating. In a conventional single stage operation, the furnace runs as a standard furnace with a single speed blower and one flame level. Dual $aver technology enables the furnace to be automatically switched to a higher stage in cases where one stage heating fails to heat up your house to a desired level.
Warranty Protection: The functional parts of the Goodman GMH80803BN 80,000 BTU 80% AFUE furnace system are covered by a Limited Parts Warranty for 10 Years. The heat exchanger is covered by a Lifetime Limited Warranty. If ever the exchanger fails within the first ten years of ownership, the company will replace the entire unit to the original registered user of the gas furnace system.
