Forge & Flame Step Top 4300

The Forge & Flame Step Top 4300, featuring Quadra-Fire burn technology, heats about 1,550–3,100 square feet. The manual lists 80.2% LHV and 74.2% HHV tested efficiency, and it's certified to the 2020 EPA wood heater standard at 1.6 grams per hour.

You pick a door and a base, since both are separate selections. Doors come arched in classic black, arched with satin nickel trim, or rectangular, all cast iron. Bases include a pedestal, Queen Anne legs in black or satin nickel, or traditional black legs.

The pedestal and the Queen Anne legs include it, while the traditional legs don't. Once the stove and ashes are completely cool, you lower the ash door handle under the stove, lift the cast iron cap inside the firebox, and sweep ash down the channel into the drawer, leaving about 1/4 to 1/2 inch on the firebox floor for airflow.

A load lasts approximately 8–12 hours. The 2.26 cubic foot firebox takes logs up to 18 inches, which is enough to carry a fire from evening through the night.

Not at start-up. Automatic Combustion Control adds air while the fire gets going and closes on its own in about 20 minutes. After that, the burn rate control sets airflow for the heat you want.

A fan isn't standard, but you can add a 160 CFM fan kit. Other add-ons include a satin nickel door upgrade kit, which includes coordinating hinge pins and an air control handle, and an ACC outside air kit.

Yes to both, with conditions. A mobile home install can't be in a sleeping room and needs the OAK-ACC outside air kit, the legs bolted to the floor, #8 copper grounding, double-wall connector pipe, and a UL103 HT chimney with a spark-arrestor cap. An alcove install needs 6-inch double-wall connector pipe and can be no more than 48 inches deep.

It uses 6-inch vent pipe. In the US, the non-combustible floor protector must reach at least 16 inches in front of the glass and 8 inches to each side of the loading door; Canada requires 18 inches in front. The brochure gives a 31-5/8 by 41 inch minimum size.
