Forge & Flame Accentra52i-TC 24" Pellet Fireplace

In most homes the Forge & Flame Accentra52i-TC 24-inch heats 1,250–2,500 sq ft, depending on climate and layout, and Harman rates it as high as 2,600 square feet. It's built on Harman technology and uses two distribution blowers to carry heat across a large room.

Yes. The Accentra52i-TC comes with its zero-clearance box, so it builds into a framed wall and finishes with tile or stone, and that cabinet is the only permitted way to install it without a fireplace. A cabinet install vents with type PL pipe out a wall or through the roof, since flex pipe isn't approved there.

It can, if the opening is at least 24-7/8 inches wide, 15-9/16 inches deep, and 24 inches high for this 24-inch hopper model. In a masonry fireplace or a factory-built wood fireplace with a Class A chimney, it vents through 4-inch stainless steel flex pipe, and zero clearance kits adapt it to factory-built fireplaces.

The 64.5 lb hopper sits under a tinted, illuminated lid that shows the fuel level. You run it from the Easy Touch control panel, which adds scheduling, cleaning prompts, a fuel gauge, and a built-in programmable thermostat, paired with a wireless room sensor that reads the temperature where you sit.

Yes, its blowers and controls run on 120-volt household power, so it shuts down in an outage without backup. A Harman-approved UPS such as the TrippLite INTERNET750U only powers a safe, smoke-clearing shutdown, while an approved inverter/charger on a 12-volt deep-cycle battery can run it for up to eight hours.

It has a 76% efficiency rating, a weighted average on the higher heating value, and it's EPA certified at 1.1 grams per hour. Harman says it needs up to 50% less maintenance than other pellet inserts, and its PelletPro feed system is designed to burn any grade of pellet fuel.

The Accentra52i-TC 24-inch pairs two blowers with the larger 64.5 lb hopper, and of the two inserts, only the Accentra comes in Majolica Brown porcelain as well as Matte Black. The P42i-TC is a bit more efficient, at 79% versus 76% on the higher heating value, and both come standard with the small surround.

Yes, the Accentra52i-TC is approved for mobile homes when it isn't in a sleeping room. The install needs a Harman outside air kit, listed Class PL connector pipe, and a ground to the home's frame with at least 8 AWG copper wire, and the home's floor, ceiling, and walls must stay structurally intact.
