Our take on the 80,000 BTU Low NOx Two-Stage Up/Horz ECM Var Spd Comm Compatible Gas Furnace 80% 115/60/1 CFM: 2000

This is an 80% AFUE gas furnace with a two-stage gas valve and a variable-speed ECM blower rated for up to 2,000 CFM. It installs upflow or horizontal left/right and is built as a low-NOx unit, so it suits regions with stricter emissions rules. The two-stage valve and variable-speed motor give gentler, quieter heat output than a single-stage furnace, though at 80% AFUE it burns more fuel than 90%+ condensing models. It is communicating-compatible with Comfortbridge controls, which adds zoning and diagnostics options.

Questions and answers

What does two-stage mean here?
The gas valve has a low and a high stage. It runs on low most of the time for steadier, quieter heat and switches to high on cold days.
Is this furnace efficient?
It is rated 80% AFUE. That is standard for non-condensing furnaces but below the 90%+ condensing models, so expect higher gas use than those.
Can it run on propane?
Yes, with a propane conversion kit. The kit is not included and must be ordered separately.
What does the variable-speed ECM motor do for me?
It adjusts blower speed to match demand, so airflow is gentler and the fan is quieter than a fixed-speed motor. It also supports more precise Comfortbridge control.
What is in the box?
The furnace unit in manufacturer packaging. The propane kit and any communicating thermostat or control are not included.
Does it fit my existing setup?
It installs upflow or horizontal left or right and needs a 115 V, single-phase circuit with a breaker sized between the listed minimum and maximum. Duct and venting work should be checked by an installer.
