TL2.0 Woodburning Stove
3. Grates
The 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.
C. Burning as a Fireplace
This appliance has been tested and approved for burning as an open fireplace. To do so, a spark screen (Harman part#
The Cozy Screen can be used from the start of a fire or can be used with an existing one. When starting a fire with the Cozy Screen, smoke spillage may occur until it develops a draft strong enough to pull all smoke back into the flue.
DO NOT LEAVE THE APPLIANCE UNATTENDED WITH THE DOOR OPEN!
Load only small amounts of wood at a time.
D. The Combustion Process
Combustion in the firebox 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 Plus" combustion package where the "Secondary Combustion", or
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 ventillation to the room where the apliance is located, to prevent air starvation. In tight construction, consider installing outside air to the appliance.
