Our take on the 66,000 BTU Two-Stage Multiposition ECM Variable Speed Gas Furnace 80% AFUE

A two-stage, multiposition gas furnace with an ECM variable-speed blower, rated 66,000 BTU input and 53,000 BTU output at 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 variable-speed ECM motor moves up to 2,000 CFM quietly and draws less power than a standard PSC blower. It suits a mid-size home in a mild-to-moderate climate, or a shop or addition where a full condensing furnace is not needed. Against 90%+ condensing rivals it gives up efficiency and needs no PVC venting or condensate drain, which keeps installation simpler. It runs on natural gas; a propane conversion kit is sold separately.

Questions and answers

Is a two-stage furnace worth it over a single-stage?
Yes for comfort. Low fire runs longer and gentler, so room temperatures swing less and the burner cycles less. The trade-off is a higher unit cost than a single-stage model.
Does it work with propane?
It ships set up for natural gas. Running propane requires the AGAGC8NPS01B conversion kit, which is not included and must be installed by a qualified technician.
What size home does 66,000 BTU suit?
The 53,000 BTU output fits a mid-size home in a moderate climate. In cold climates or a large, poorly insulated house, a larger output or a condensing furnace is the better match. A load calculation decides it.
Can it be installed horizontally or in a downflow position?
Yes. The multiposition cabinet supports upflow, downflow and horizontal installations, which gives the installer flexibility in tight spaces.
Does it cool the house?
No. It is a heating-only furnace. It can share ductwork with a separate air conditioner or coil, but cooling equipment is not part of it.
Why choose 80% AFUE instead of a 90%+ furnace?
An 80% furnace vents through a standard metal flue and needs no condensate drain or PVC piping, so the install is simpler and often cheaper. The cost is lower efficiency and higher gas use.
Where is the 66,000 BTU Two-Stage Multiposition ECM Variable Speed Gas Furnace 80% AFUE cheapest?
