Primary Air - Osburn STRATFORD Installation Instructions Manual

under the wood for a more efficient burn. Once you have reached the desired temperature, the
primary air can be set to a medium setting. You know you have reached the desired temperature
when, closing the primary air control, you can see a flame at the top of the firebox. The benefit of
this technique will be cleaner glass, less creosoting, greater efficiency and the most pleasing fire
for your enjoyment.
In order to achieve an optimum efficiency from your unit, we suggest that you operate it with the
air control completely closed. 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.

2.2.6 Primary Air

There is no flue damper in the OSBURN STRATFORD. As in common with air tight stoves, the
combustion air control sets the flow of air entering the firebox. This allows for a more precise
control of the fire. The combustion air control is located below the door on the right side. The
main source of air (primary air) entering the firebox can be diminished by moving the air
combustion control from right to left. The primary air is fully opened when the air control is
completely moved to the right. The combustion air control should be in the closed position
(primary air) when the fireplace is not in use. This will minimize air leakage up the chimney. The
combustion air control should be opened before opening the door to minimize the possibility of
back draft coming into the room.
