Forge & Flame P42I-TC Pellet Insert - 20" - Matte Black, Powered by Harman Technology
The 20 inch Harman P42i-TC is the version built for shorter fireplace openings. It needs an opening just 20 inches tall, which opens up pellet heat for fireplaces that can't take the 24 inch version.
The cast iron face in Matte Black looks at home in front of brick or stone, and flame-reactive mirrored glass shows off the fire. The 20 inch model's hopper holds 47.5 lb, with an illuminated glass lid for quick checks. EASY Touch Control includes a programmable thermostat, and a 134 cfm blower moves the heat into the room. Harman rates it at 79% efficiency (HHV).
What Makes the P42i-TC (20 in) Different
- Fits a 20 inch opening. This version needs a minimum fireplace opening only 20 inches high, 24-7/8 inches wide, and 15-9/16 inches deep.
- A cast iron face. The cast iron face gives the P42i-TC a traditional, substantial look in front of an existing fireplace.
- EASY Touch with a programmable thermostat. Set a schedule on the built-in programmable thermostat, and the wireless room sensor and ESP control hold the room within one degree, according to Harman.
- Insert track system. The insert sits on a track system, so it's easier to slide out when service time comes.
