HEATING
Controlled combustion is the most efficient technique for wood heating because it enables
you to select the type of combustion you want for each given situation. The wood will burn
slowly if the wood insert air intake control is adjusted to reduce the oxygen supply in the
combustion chamber to a minimum. On the other hand, wood will burn quickly if the air
control is adjusted to admit a larger quantity of oxygen in the combustion chamber. The
air intake control on your insert is very simple. If you move it completely to the right, it is
fully open. If you move it completely to the left, it is fully close.
Your OSBURN insert burnt between .979 kg\h and 4.4 kg\h. of wood during EPA testing.
Real operating conditions may give very different results than those obtained in the lab
according to the species of wood used, its moisture content, the size and density of the
pieces, the length of the chimney, altitude and outside temperature.
In order to achieve an optimum efficiency from your unit, we suggest that you operate it
with the air control slightly open (approximately 10%). Make sure that you have a good
fire going and an adequate ember bed before you completely close the air control. Closing
the air control too soon will lower combustion efficiency and may cause the fire to die out.
The addition of a blower (if not already included) is highly recommended to maximize your
unit’s efficiency.

RELOADING
Once you have obtained a good bed of embers, you should reload the unit. In order to do
so, open the air controls to maximum a few seconds prior to opening the insert's door.
Then proceed by opening the door very slowly; open it one or two inches for 5 to 10
seconds, before opening it completely to increase the draught and thus eliminate the
smoke which is stagnant in a state of slow combustion in the insert. Then bring the red
embers to the front of the insert and reload the unit.
For optimal operation of your wood insert, we recommend you to operate it with a wood
load approximately equivalent to the height of fire bricks.
It is important to note that wood combustion consumes ambient oxygen in the room .In the
case of negative pressure, it is a good idea to allow fresh air in the room, either by opening
a window slightly or by installing a fresh air intake system on an outside wall.
