OPERATING THE PRIMARY AND SECONDARY AIR SETTINGS
Primary air- is the driving air supply that feeds the fire in the heater. This air is introduced through the damper in
the feed door to sustain the combustion.
Secondary air – is the air supply that is typically introduced above the fire to effectively “re-burn” the smoke
created in the primary combustion before the exhaust gasses exit the stove. This air is preheated before being
injected into the heater so it can react with (re-burn) the smoke when they mix.
When increasing the amount of primary air supplied to the heater, the secondary should also be increased as
well to ensure a clean burn.
Rear Pilot/Tertiary Air – The air that is introduced at the back of the firebox and is to help sustain heat in the
secondary air to help ensure a cleaner burn.
Start up: During Start-up the Primary and the Secondary air adjustments should be in the fully open or the “High”
setting positions. This allows for the maximum amount of combustion air during the initial start-up to insure the
fastest and cleanest start-up. The primary air will be in the “High” position when the thermostat is calling for heat.
These settings should remain open until the stove has heated up and an adequate fire has been established.
Once the fire is well established, both the primary and the secondary air settings can be adjusted down to the
desired heat setting. The primary and the secondary air mix inside the firebox to provide a more efficient and
cleaner burn. We encourage that you get to know your stove and how it reacts to adjusting both the primary
and the secondary air dampers so that you can achieve the best burn possible for the type of wood and the
draft situations in your particular installation.
