6. Operation
Read the following section carefully before building a fire
in your stove.
6.1 Fuel
This stove is designed to burn natural wood and biofuels
ONLY. Wood that has been air-dried for a period of 6 to
14 months will provide the cleanest, most efficient heat.
Hardwoods are preferable to softwoods. Frequent use of
green or inadequately seasoned wood is conducive to
creosote accumulation and generally poor performance.
DO NOT BURN...
• Coal
• Treated or painted wood
• Garbage
• Chemical Chimney cleaners
• Cardboard
• Colored paper
• Solvents
• Any synthetic fuel or logs
The burning of any of these materials can result in the
release of toxic fumes. NEVER USE GASOLINE, GASOLINE-
TYPE LANTERN FUEL, KEROSENE, CHARCOAL LIGHTER
FLUID, OR SIMILAR LIQUIDS TO START OR "FRESHEN-UP"
THE FIRE. Always keep such liquids away from the heater
at all times.
WARNING!
NEVER ALLOW THE FIRE TO REST
DIRECTLY ON THE GLASS.
THE LOGS SHOULD ALWAYS BE
SPACED AT LEAST ONE INCH FROM
THE GLASS TO ALLOW FOR PROPER
AIR FLOW WITHIN THE STOVE.
OPERATE THIS STOVE ONLY WITH THE
DOOR FULLY CLOSED. OPERATION
WITH A PARTIALLY OPENED DOOR MAY
RESULT IN OVER-FIRING. ALSO, IF THE
DOOR IS LEFT PARTLY OPEN, GAS AND
FLAME MAY BE DRAWN OUT OF THE
STOVE OPENING, CREATING RISKS
FROM BOTH FIRE AND SMOKE.
WARNING!
NEVER OVER-FIRE THE STOVE. IF ANY
PART OF THE STOVE OR CHIMNEY
GLOWS, YOU ARE OVER-FIRING. A
HOUSE FIRE OR SERIOUS DAMAGE
TO THE STOVE OR CHIMNEY COULD
RESULT. IF THIS CONDITION OCCURS,
IMMEDIATELY CLOSE THE AIR
CONTROL.

6.2 Air Control Settings
A single lever regulates the Primary Air flow that controls
the intensity of the fire and consequent heat output and
burn time. The lever is located within the slot above the
stove door.
Primary Air enters the stove above the door and
washes over the glass before reaching the fuel. A second
source of primary air reaches the fire through the small
pilot tube at the front of the firebox. Unrestricted
secondary air is delivered through manifolds at the rear
and top baffle where it ignites volatile gases that would
otherwise pass unburned into the environment. See
fig. 19. In this way, the wood is burned efficiently and
exhaust is minimized. When the fire is burning well, little
or no smoke will be evident from the chimney.
When first starting or reviving the fire, the control
lever should be set at the far right position to allow the
maximum amount of air into the stove. See fig. 19a.
After the fire is well-established, the lever should be set
at position to moderate incoming air to maintain the
desired long term heat output and/or burn time.
In general, the more air made available to the fuel
will result in the hottest fire intensity and the fastest fuel
consumption. Alternatively, the less air made available to
the firebox will result in low heat output and slower fuel
consumption.
