Understanding Your Heater’s Combustion System
This heater uses a dual combustion system detailed below:
Primary Combustion : This is the combustion (fire) that takes place directly on the wood. Primary combustion
determines how fast the fire burns. Air for primary combustion is supplied through the air control. When you adjust
the air control you control the amount of air that reaches the fire and creates primary combustion. The air control
supplies air to the air wash (the air holes above the door opening – used to help clean the glass) and through the
pilot orifice (center bottom of the door opening). By using the air control, and supplying air through these two
openings, you control primary combustion.
Secondary & Catalytic Combustion : This is the combustion (fire) that does not contact the wood. Secondary
combustion burns the visible emissions or smoke that is not consumed during primary combustion. It takes place at
the top of the firebox and can appear as a glowing flame near the secondary air tubes. Catalytic combustion takes
place inside the catalytic combustor and is not viewable (you may, however, see the combustor glow). It also burns
the visible emissions or smoke that is not consumed during primary combustion. Catalytic combustion can be
monitored by using the included temperature meter. Your catalytic combustor is working when the output
temperature is above 500° F. (260°C).
Items to Consider:

During medium and high burn rates the stove will manage secondary and primary combustion on its own. When
the heater is set to a low burn rate more care is needed to ensure the secondary combustion system works
properly. Make sure the stove is hot and a good coal bed is established before adjusting your heater to low burn.

Understanding the combustion system in this heater will help minimize the visible emissions this heater releases
into the environment. The primary pilot orifice at the center bottom of the door opening is designed to help the
secondary combustion at low burn settings. The pilot provides a small amount of air that burns up through the fuel
load providing the heat and flame needed for the secondary system to ignite. The air tubes under the baffle need
to remain ignited for low burns to be effective.

As you load your heater for a low burn, take care in placing the wood. This will affect how well your secondary
system works as the wood is consumed. Do not block the pilot orifice. Stack wood so the pilot air can burn its
way up between the pieces, helping your heater burn effectively throughout the low fire. This will reduce the
visible emissions your heater produces and increase the amount of heat you get from the wood. If you are unsure
how well your heater is burning look at the chimney cap to monitor visible emissions.
Burning Your Heater
Starting a Fire: Make sure your air control is all the way open and the by-pass is in the open position. To
reduce the amount of smoke when starting your fire, the “Top Down” method described below allows for
the cleanest starts. Start with 2 large pieces of kindling 1”- 2” in diameter laid side to side on the firebox
floor. Using small ½” to 1” diameter split kindling, 3 layers in a crisscross pattern using 5 to 6 pieces per
layer. Places an additional 2 layers of larger kindling on the very top and light the middle of the stack.
Shut the by-pass after the fire is established and the door in 2-3 minutes. If the fire starts to die down,
reopen the by-pass and door and leave it cracked open until the fire recovers and becomes established.
Never leave your heater unattended if the door is not latched shut. Reload the stove when the
kindling pile has burned about three-quarters of the way through with 15” medium sized pieces of
cordwood. Place a layer of 2 pieces orientated side to side on the coal bed and 3 pieces on top oriented
front to back. A hot coal bed is critical to clean combustion of the fuel. We cannot overstate the
importance of a hot coal bed before slowing down the burn rate by adjusting the air control. Burn the first
full load of cordwood completely through at the high burn rate to get our heater up to a good operating
temperature and to establish a deep coal bed before reloading and adjusting the burn rate.
Reloading: When reloading a hot stove, return the air control too high for at least 15 min before adjusting
the air control to slow down the burn rate .
Low & Medium Burns:
If preparing for a medium or low overnight burn, a longer heat-up period may be
necessary. For the lowest emissions we recommend the following method: using 15” cord wood load the
unit with a layer of 2 pieces orientated side to side on the coal bed and 4 pieces on top oriented front to
back. After loading, burn the stove on high for at least 15 minutes before setting the air control to low.
Excessive creosote buildup (or sooting) in the heater at the end of a low burn signifies that the heater was
not hot enough and the wood load was not burned long enough on high after loading before adjusting the
air control.
