Osburn Matrix Inbuilt Installation and Operation Manual
The table below provides a very general indication of the maximum burn cycle times you are likely
to experience, based on firebox volume.
Long burn times are not necessarily an indication of efficient wood inbuilt operation. When you
are home during the day and able to tend the fire, it is preferable to build a smaller fire that might
provide three or four hours of heating than to fully load the firebox for a much longer burn.
Shorter burn cycles make it easier to match the heat output of the wood inbuilt to the heat
demand of the space.
