Forge & Flame Expedition II

The Forge & Flame Expedition II, featuring Quadra-Fire burn technology, heats about 1,400–2,800 square feet. It's rated 71% efficient on the higher heating value and is certified to the 2020 EPA wood heater standard at 1.9 grams per hour.

Activate the start-up air control by pushing it back until it stops and pulling it forward until it stops, when you light a fire and again each time you reload. ACC gives the new fire extra air, then settles it down on its own. There's no burn rate dial, so you set heat by how many logs you load and whether they're split.

Its 2.37 cubic foot firebox takes logs up to 20 inches long, and a full load burns for roughly 5–7 hours. That means you'll usually want to reload before bed rather than count on an overnight burn.

The standard minimum opening is 23-3/8 inches tall, 32 inches wide at the front, 23-7/8 inches wide at the back, and 18-1/4 inches deep with the steel surround. You'll also need a full-length insulated 6-inch stainless steel chimney liner, which UL 1390 requires.

No to both. It's approved only for masonry fireplaces with masonry chimneys, including ones with metal heat-circulating parts, but not listed factory-built or zero-clearance fireplaces. The manual also states it's not approved for mobile homes in the US or Canada.

Yes. The standard blower plugs into household power, drawing 1.4 amps at 115 volts, and on AUTO a snap disc turns it on and off with the stove's temperature, while MANUAL leaves it up to you. The manual recommends leaving it off for the first 30 minutes of a cold start.

In the US, the hearth extension must reach 17-1/2 inches in front (19-1/2 inches in Canada). If the bottom of the insert sits less than 4.5 inches above that extension, it needs thermal protection with an R-value of 2.9; at 4.5 inches or more, ember protection alone is enough.

A surround is required but sold separately. Choose a medium or large metal surround, a metal surround with cast trim, or a custom surround to frame the arched cast iron door, then add a Fillmore or Ozark wood mantel, a non-combustible shelf, or an outside air kit.
