* Burn time and heating capacity may vary subject to location in home, chimney draft,
chimney diameter, locality, heat loss factors, climate, fuels and other variables.
** The EPA test fuel is dimensional Douglas fir pieces stapled together into cribs with air
spaces between. We also test using the same procedure except using split hardwood
firewood to reflect real-world heat output. This stove is not intended to operate at its peak
heat output continuously.
*** East-west: through the door you see the sides of the logs; north-south: through the door
you see the ends of the logs
