* Combustion autonomy and heating capacity may vary subject to location in home, chimney draft,
chimney diameter, locality, heat loss factors, climate or fuels.
** 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
