C. The Combustion Process

Combustion in the Harman Oakleaf is precisely controlled 

and is best explained in two parts.
During a wood fire, combustion air enters at the bottom front 

of the stove where it travels upward through channels at either 

side of the front door. From the manifold located above the 

front door, it is directed into the firebox as a sheet of air flowing 

between the glass and the wood. This concept helps to keep 

the glass clean, while providing the oxygen needed to sustain 

burning. This is what is known as "Primary Combustion". 
Additional air enters at the bottom rear of the stove body. 

Some  of  this  air  enters  through  holes  in  the  rear  bricks 

where it is used to revitalize the fire at the rear of the firebox. 

The remainder is delivered into the "Firedome" combustion 

package where the "Secondary Combustion", or re-burning 

of the smoke, occurs.
During combustion, the burning of wood proceeds through 

several  stages. The  initial  or  evaporation  stage  is  where 

the moisture in the wood is driven off in the form of steam. 

A second stage is where the volatile gases contained in the 

wood are released and burned. This represents most of the 

wood's heating capacity. The final stage is the charcoal stage 

where the charcoal burns the remaining heat content in the 

wood fuel. Ash remains after the burning is complete. Within 

the primary firebox two or more of these stages of combustion 

are occurring at once.
Always be sure to provide adequate ventilation to the room 

where  the  appliance  is  located,  to  prevent  air  starvation. 

In  tight  construction,  consider  installing  outside  air  to  the 

appliance.

3. Grates 

The  Harman  Oakleaf's  unique  grate  system 

consists  of  one

 

flat  bottom  grate,  and  two  front 

andirons. The bottom grate has slots which allow 

the ash to fall into the ash pan by passing a poker 

back and forth across the grate. The andirons keep 

the fuel from coming into direct contact with the 

glass, and keep hot coals and embers from spilling 

out  while  reloading.  Never  build  a  fire  directly 

against the glass.

The grates and andirons must remain in place 

at all times. Do not tamper with or change the 

configuration of this grate system.

2. Doors

Your stove has a large glass-paneled door for loading and 

fire viewing, a separate smaller door for removing ashes and 

a top loading door. 

Front Door

Before opening, always check for wood, embers, or ash that 

may be ready to fall out of the door. 
To open the glass door, open the bypass damper first, then 

turn the handle clockwise and pull out; to close the door, push 

the door closed with the handle in the open position, then 

turn, counter-clockwise, to engage the latch. 

Ash Door

To open the ash door, lift up the handle and pull out. Close the 

door by pushing in and pushing the handle all the way down. 

Top Load Door

To open the top load door, open the bypass damper and then 

lift to open the top load door.
All  doors  must  be  closed  while  the  stove  is  in  normal 

operation, and the gaskets routinely examined for wear and 

replaced when necessary. Good door seals are important 

for maintaining control of the stove. Never operate with the 

ash door open. Operating the stove with the ash door open, 

or with a door inadequately sealed, could create a serious 

overfiring condition (discussed later in this section).
The glass used in your Oakleaf is manufactured to exact 

standards to withstand the high heat of the fire, but like all 

glass, it must be treated with common sense and care. Never 

abuse the glass by slamming the door shut or striking the 

glass with a heavy object. If the glass is broken or damaged, 

do not operate the stove until it has been replaced 
(See instructions in the Maintenance section.)
