Forge & Flame Absolute43

Harman rates the Absolute43 for up to 2,400 sq ft, but in most homes you can expect 1,100–2,200 sq ft depending on climate and layout. Its BTU input runs from 14,100 to 44,200 per hour, with 77% HHV efficiency and EPA-certified emissions of 0.99 g/hr.

The Absolute43 is the compact one, with a 52 lb hopper against the Absolute63's 72 lb and a 2,400 sq ft rating against 3,400 sq ft. For a large home, the Absolute63 is the better fit. Both have a tinted, LED-lit hopper lid so you can check fuel at a glance.

Its variable-speed blowers ramp up and down with the fire instead of running full blast. A wireless room sensor reports the actual room temperature to the EASY Touch Control, and an exhaust sensing probe adjusts output to hold your setting. The touch screen also has scheduling, diagnostics, cleaning prompts, and a fuel gauge.

Scrape the burn pot every time you add pellets or at least every three bags, and empty the large concealed ash pan weekly; the stove can stay on low while you do. With the stove off, cold and unplugged, clean the glass, heat exchanger, distribution fan and igniter regularly, then do a yearly total clean of the combustion fan and venting before each season.

The combustion blower stops, so the stove can't keep burning normally and some exhaust may seep into the room. An approved UPS (TrippLite INTERNET750U) powers a safe shutdown, while an approved inverter/charger on a 12-volt deep cycle battery can run the stove for up to eight hours.

It needs 2 inches from the back wall, 6 inches from a side wall, or 6-1/4 inches in a corner, though 3-inch PL vent pipe needs 3 inches of its own clearance. Alcoves must be at least 42 inches high and 36 inches wide and no more than 24 inches deep. In the US, the floor protector extends 6 inches to the sides and front and 1 inch behind.

Yes, it's approved for mobile homes when it isn't in a sleeping room. The maker's outside air kit must be installed for combustion air, and the stove must be grounded to the frame of the home. It vents through 3-inch pipe.

The cast iron body comes in Black, Majolica Brown, or limited-edition Sand. You can add an outside temperature kit or a Harman Protect cast iron hearth pad. Only dealers trained on the Absolute43 can order and install it.
