Our take on the 80,000 BTU Two-Stage Upflow/Horizontal ECM Multi Speed Gas Furnace 80% AFUE 115/60/1 CFM: 2000

A two-stage gas furnace with 80,000 BTU input and 64,000 BTU output, rated 80% AFUE. The two-stage burner runs at low fire most of the time for steadier heat and less on-off cycling than a single-stage furnace, and the multi-speed ECM blower moves up to 2000 CFM while using less power than a standard PSC motor. It is set up for upflow or horizontal installation, uses non-communicating controls, and fits residential, multi-family and light commercial jobs. It is a builder-grade 80% unit, so it vents through a metal flue rather than PVC and costs more to run than a 90%+ condensing furnace.

Questions and answers

Is a two-stage furnace worth it over single-stage?
Yes for comfort. Low fire runs longer and quieter with fewer temperature swings, and high fire only kicks in on cold days. The trade-off is a higher equipment cost than a basic single-stage model.
Does 80% AFUE mean it vents through a chimney?
Yes. At 80% AFUE it is a non-condensing furnace, so it vents through a metal flue. A 90%+ condensing furnace vents through PVC but produces acidic condensate that needs a drain.
Can it be converted to propane?
Yes, with the LPM-06 propane conversion kit, which is not included. Have a licensed technician do the conversion and set the gas pressure.
What controls does it work with?
It uses non-communicating controls, so it works with standard 24V thermostats, including two-stage models. It will not support proprietary communicating thermostat features.
What is in the box?
The furnace unit only. The propane kit, thermostat, venting, coil and condensate parts are separate.
Can it be installed horizontally?
Yes. The cabinet is configured for upflow or horizontal installation. Ductwork and venting must be redone for the orientation you choose.
Where is the 80,000 BTU Two-Stage Upflow/Horizontal ECM Multi Speed Gas Furnace 80% AFUE 115/60/1 CFM: 2000 cheapest?
