Air enters the stove through either the Boost, Primary or Secondary channels.
Primary (used for smokeless fuel, which requires air from underneath to burn)
Air enters the stove from the underside and travels directly into the firebox.
This air is warmed as it enters the firebox from the heat produced from combustion.
Flue and Chimney
Exhaust gases travel upward and across the top of the throat plate.
They then continue up the flue and out of the top of the chimney.
Boost, (for those models with a boost disc)
When the air boost disc is opened the air flows into the stove body.
The air is warmed from the heat of the combustion in the firebox.
It then enters the firebox from underneath and helps provide air to aid with combustion.
Secondary (used for wood, which requires air from at the top to burn)
The air enters the back of the stove and travels up the back channel.
This air is warmed as it travels up.
Air can then take two paths: either into the firebox through the tertiary air bars, or travels over the throat plate and down the glass through the air wash system, which helps to keep the glass clean.
