Forge & Flame Pathfinder P43 Pellet Stove, Powered by Harman Technology


The Harman P43 is a straightforward pellet stove that does the job with very little attention. Automatic ignition and temperature control, plus Harman's room sensor, regulate the room within one degree. If you'd rather run it at a steady rate, Constant Burn Mode does that too.

It's the compact one in Harman's P-Series lineup, at 20-3/4 inches wide and 33-1/2 inches tall, with a cast iron front door and a 50 lb hopper. An accordion heat exchanger, an air wash system that helps keep the glass clean, and a large ash pan make it easy to live with. Brushed stainless trim kits and tiles are available if you want to dress it up.

What Makes the P43 Different

  • Two ways to run it. Room Temp Mode lets the room sensor control heat output, and Constant Burn Mode holds a steady output no matter the room temperature.
  • Accordion heat exchanger. Harman's accordion heat exchanger is part of how the P43 reaches its 76.7% efficiency (HHV) rating.
  • Cleaner glass. An air wash system helps keep the glass clear so you can see the fire.
  • Make it your own. Optional Leaf or Modern brushed stainless trim kits, slate or stainless tiles, and a 21 inch hopper extension are sold separately.
