The Combustion Process
Combustion in your Harman Exception wood
insert is controlled very precisely. During a wood fire,
primary combustion air enters the bottom of the insert,
is directed up to the top of the load door and then down
past the glass, finally entering the combustion chamber.
Secondary combustion air enters the bottom of the in-
sert and is delivered directly to the afterburner behind
the firebox, where it provides the additional oxygen re-
qu ir ed
f or clean b ur ning .
During combustion, burning proceeds through
several stages - an initial evaporation stage, where mois-
ture is released from the wood; a stage where volatile
gases containing much of the wood’s heating capacity
are released and burned; and a charcoal stage, where
the remaining charcoal burns to release the additional
heat available. What is left after this final stage is ash.
Within the firebox, two or more of these stages are gen-
erally occurring at once.
