Use Table 2.2 to adjust the draft control to the desired burn rate:
Burn Rate
Draft Setting
Low Move Control against the L.H. side.
Medium Low Move Control right by 9/16” – 1” (14.3 – 25.4mm) from closed position.
Medium High Move Control right by 7/8” - 1 3/4” (22.2 – 44.5mm) from closed
position
High Move Control against the R.H. side
Table 2.2 Draft Settings
Closing the draft control down too soon will lower combustion efficiency, and may result in creosote
build-up in the chimney (which could lead to a future chimney fire).
CAUTION: THE ADJUSTMENT RANGE SHOULD NOT BE ALTERED FOR INCREASED FIRING FOR ANY REASON.

2.5 Maintaining The Fire
Your Osburn stove will work best if a thick bed of hot embers is maintained in the bottom of the
firebox, and a minimum of two large pieces of seasoned fuel are added. Combustion efficiency is
largely related to establishing a hot ember bed, and hot firebox temperatures. The quicker the stove
and fuel get up to operating temperature, the better. A small intense fire is preferred to a large
smouldering fire, both to improve combustion efficiency and to reduce the amount of creosote
emitted. The best performance will be obtained by adding relatively small amounts of fuel to a
well established ember bed, and then operating with the air inlet control open long enough to
achieve a hot fire. Cordwood should be placed with air in between individual pieces. Use a poker
to make an air channel in the embers below the wood, this will allow air to flow under the wood for
