Superior WCT6920 EPA-Certified High-Efficiency Wood Burning Fireplace
An EPA-certified, Washington State approved wood-burning fireplace — 1.9 g/hr on cordwood, 15,277 to 55,597 BTU/hr at 72% EPA-estimated efficiency. The Superior WCT6920 is a closed-combustion circulating firebox in a traditional arch front design: stacked textured refractories, a decorative cast iron log retainer, a factory-installed 200 cfm heat-activated blower, and the mandatory outside air kit already in the box. from $5,249.
Choose the WCT6920 if you want the traditional arched look with real wood heat — the arch facade and arched steel or cast iron doors are ordered with it — in a firebox that frames into the same 37-1/4" x 56" rough opening as the WCT4920 and heats up to 1,500 square feet as a supplemental heater. Washington State approval makes it the pick where the state's stricter emissions rules apply.
It is not right if you cannot run a full vertical chimney — this firebox needs a listed 6" wood-burning chimney at least 12 feet tall that terminates above the roof, not a wall vent. If there is no chimney path, a direct-vent gas fireplace such as Superior's DRT3000 series vents straight out a side wall and is the one to look at instead.
Specifications
Frame a rough opening 37-1/4" wide by 56" high, 25-1/8" deep for a flush install — framing dimensions include sheathing. Keep side walls 24" clear of the firebox opening, hold any mantel to non-combustible material at least 39-1/2" above the base, and cover the floor in front with non-combustible material sized per Figure 8 on page 9 of the installation manual. It vents on 6" IHP Snap-Pak chimney in the US — minimum 12 feet, 2" clearance, rain cap on top — and can also connect to a masonry chimney with a 2100°F-rated stainless liner.
How the WCT6920 compares to the other Superior wood fireplaces
The WCT4920 shares this firebox platform and output but wears smooth refractories, a steel log retainer and a wider choice of fronts — square and Clean Face as well as arched — at from $5,099 against this model's from $5,249. The WCT6940 at from $7,469 is the big catalytic unit: a 4.0 cubic foot firebox, 30" logs and up to 80,000 BTU/hr on a 7" chimney, but it is not approved for manufactured homes — this WCT6920 and the WCT4920 are.

Answers to common questions
What’s included, what’s required, and what’s optional?
-
Included in the box: Stacked textured refractory interior panels with integrated ash lip and cast iron log retainer; Factory-installed heat-activated blower with VRUW variable speed control; Insulated outside air kit (mandatory for every installation, in the box); Damper rod and handle, junction box and rheostat, intake vent, insulation sleeve, outside air intake pipe, ember strip, finishing guide plate and top standoff assembly; EPA certified; UL 127 / CAN/ULC S610 listed (PFS TECO); 20-year limited warranty.
-
Required to complete the installation, purchased separately: Front - a decorative facade; ships separately and is required to complete installation (the black arched facade takes either arched door); Doors - a door set; the fireplace cannot be operated without a door — smooth steel or cast iron arched; Venting - a 6" chimney run, IHP Snap-Pak in the US (Secure Temp or DuraTech in Canada), minimum 12 feet with a rain cap; Electrical - a 120 V connection, wired by a qualified electrician before the fireplace is installed; Floor Protection - non-combustible hearth-extension floor protection built on site, sized per Figure 8 on page 9 of the installation manual.
-
Optional: The HeatFlo convection kit ducts heat to one or two more rooms and the thermostatic forced air kit pushes it further — the fireplace heats fully without either.
What chimney does it need?
A 6" diameter listed wood-burning chimney on every configuration — IHP Snap-Pak in the United States, Secure Temp ASHT+/S2100+ or DuraVent DuraTech in Canada. Plan a minimum of 12 feet of chimney not counting the fireplace (15 feet if the run uses offsets), add 18" per 2,000 feet of elevation, keep 2" clearance to combustibles, and finish with a rain cap. It can also tie into a new or existing masonry chimney with a 2100°F-rated stainless liner. Send us your roof height and we will size the run with you.
Will it heat if the power goes out?
Yes — every configuration burns wood with no electricity at all; the fire needs no power. Electricity runs only the 200 cfm circulating blower, which is on a 120 V connection and will not spin in an outage; the fireplace still radiates heat through the ceramic glass while the power is off.
Can I install it in a mobile or manufactured home?
Yes — the WCT6920 is approved for mobile and manufactured homes with solid fuel only. The installation must follow HUD requirements in the US (CMHC in Canada), the fireplace must be fastened to the floor with its tabs, and it may not be installed in a sleeping room.
Can it heat more than one room?
Yes — on its own the blower circulates room air, and two ducting options extend the reach: the HeatFlo convection kit shares warm air by natural convection up to 10 feet into one or two adjacent rooms, and the thermostatic forced air kit pushes heat further. Both are below-the-cart accessories; note the book's caveat that the forced air kit was not part of the EPA emissions testing, so it cannot be sold as EPA certified.
What wood should I burn, and how long does a load last?
Dry, seasoned natural cordwood only — 15-20% moisture is the target, and hardwoods burn longest; treated wood, plywood, trash and coal are prohibited. Loaded and set to the recommended medium combustion it reloads about every 3-4 hours; run slow overnight it goes 6-8 hours. It is a supplemental heater, so keep another heat source for the house.
How does the warranty work if something goes wrong?
Superior warrants the fireplace — 20 years limited on the body, firebox and ceramic glass — and The Torch Guys handles it for you: we register the appliance and, if you ever need to claim, we deal with the manufacturer on your behalf rather than handing you a phone number. Keep your invoice and the model number; we hold the rest on file.
