Operation

The Combustion Process

Combustion in the Harman TL300 is precisely controlled and is divided into two parts.

During combustion, primary air enters at the bottom front of the stove and travels up channels at either side of the front door. This pre-heated air then enters the manifold, located above the front door, where it is released into the firebox as a sheet of air between the glass and the fire. This air-wash system cleans the glass as it provides oxygen to the firebox.

Secondary combustion air enters the stove at the bottom rear of the stove. Here, in the "Firedome", it mixes additional oxygen with the exhaust, causing it to be re-burned. This secondary combustion is necessary to achieve and sustain long, clean burning.

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. During the second stage, 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 out of the fuel. Ash remains after the burning is complete. Within the primary firebox, two or more of these stages of combustion are occurring simultaneously.

Two important controls - the top load door handle and the air control lever regulate the operation and output of the stove.

Top loading door handle/damper interlock. The top loading door handle is linked to the bypass damper and serves two purposes. Move the handle forward one position (approximately 3") and the handle automatically opens the bypass damper, you must open the bypass damper, or smoke will come into the room. In this mode of operation the combustion gases go directly from the main combustion chamber to the flue collar and exit into the chimney.

Continue moving and lifting the handle and it opens the top loading door.

NOTE: The bypass damper must be open for smokeless loading. Open the bypass damper by pulling the handle toward the front of the stove.
