Forge & Flame Accentra52i-TC 20"

The Forge & Flame Accentra52i-TC 20-inch, powered by Harman technology, heats about 1,250–2,500 square feet from your fireplace. It's rated 76% efficient on the higher heating value and is certified to the 2020 EPA particulate standard at 1.1 grams per hour.

It moves heat with two distribution blowers, so warm air reaches past the front of the room. With the optional service rail kit, the insert slides forward out of the fireplace for service, and the lighted glass hopper lid lets you check pellets at a glance.

The 20-inch model needs an opening at least 20 inches tall, 24-7/8 inches wide, and 15-9/16 inches deep. The shorter hopper holds 47.5 pounds of pellets, so if your opening is 24 inches tall, the 24-inch model fits 64.5 pounds instead.

You set it on the EASY Touch Control panel on the insert, and a wireless room sensor tells the insert what the room actually feels like. If the sensor's two AA batteries die, a backup sensor keeps heating, and on-screen prompts tell you when to scrape the burn pot or empty the ash pan.

It needs electricity to run. The tested TrippLite INTERNET750U UPS gives you a safe shutdown only, while an approved inverter/charger on a 12-volt deep-cycle battery can keep the insert running for up to eight hours.

Yes, with conditions. A factory-built wood fireplace needs installation kit #1-00-574205 and a UL 103HT chimney or a full-height liner, and with no fireplace you use the Zero Clearance Cabinet #1-00-574323. Mobile homes are approved outside sleeping rooms with an outside air kit, listed PL vent, and a ground wire to the frame.

Allow 12 inches from the insert body to a side wall and to a 12-inch-deep mantel, with zero clearance to 3/4-inch trim. Non-combustible floor protection must reach 6 inches in front of the glass and 6 inches beside the stove body, at least 16.5 inches deep by 30 inches wide.

Choose Matte Black or Porcelain Majolica Brown, then add a ceramic log with its bracket kit, a surround extension or custom surround, a service rail kit, an outside temperature kit, or zero clearance kits. Only dealers trained on this model can order and install it.
