Forge & Flame PP70

Plan on 1,000–2,000 sq ft, depending on your climate zone, layout, and insulation. It's sized for a medium home where the main living area needs steady heat, and its 88.5% efficiency rating is the highest in this pellet line.

The 70 lb hopper runs about 34–48 hours on a full load, so you can fill it every other day instead of daily. No hopper extension is listed for this model, so if you want a bigger fuel load, look at the largest stove in the line.

The dial has OFF, LO, HI, and comfort settings 1 through 10. On a numbered setting, the stove shuts itself down once the room reaches your comfort level and restarts automatically when it cools, while LO and HI run continuously regardless of room temperature. A 300-watt auto-igniter lights each fire.

Yes. It's approved for mobile homes when it isn't in a sleeping room and the included outside air kit is installed and kept clear. The manual also requires grounding it to the home's frame with #8 copper wire, listed double-wall connector pipe, and bolting it to the floor through holes in the cast legs.

It takes 3-inch or 4-inch type L or PL pellet pipe, and you'll need the 4-inch size if the flue is taller than 15 feet or you live above 3,000 feet. Horizontal runs top out at 48 inches without added vertical pipe, and the manual recommends at least 5 feet of vertical venting.

No. It needs 110-volt household power for the igniter, feed, and fans, and it hasn't been tested with third-party battery backups. If you plan to run it on a generator, the manual recommends a steady-state generator for the best performance.

The manual lists 9 inches from a side wall to the stove and 3 inches from the back wall. You'll also need a non-combustible hearth pad under it that extends at least 2 inches past the sides and back and 6 inches in front in the US.

It comes complete in black with the outside air kit, a cleaning tool, and a power cord, with no add-ons to choose, though venting is bought separately. The warranty covers parts only: electrical parts for 1 year and steel parts, excluding the fire pot, for 5 years.
