effectiveness of the air wash over the glass; the higher the
setting, the cleaner the glass will remain. Additional air
is separately directed into the top of the fire chamber to
support combustion of exhaust gasses before passing
out of the stove. This unregulated Secondary Air enters
through the inlet in the rear of the firebox and is heated
as it passes over the back into a two-tiered manifold
at the top of the firechamber. Volatile gases, released
unburned from the fuel bed, rise to the baffle where they
are turbulently mixed with the hot, fresh oxygen. Secon-
dary combustion then occurs before the gases pass into the
heat exchange chamber.

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. This lever is located within the
slot on the upper right front of the fireplace insert. See
fig. 19
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.15.
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
Break-in Period
The cast iron parts of your fireplace insert require a
break-in process to allow them to gradually adjust to
thermal expansion and contraction. This is accomplished
by building a series of three or four fires, each somewhat
hotter than the last. Allow the fireplace insert to cool
completely before building the next fire.
Limit the first fire to just kindling and a couple of 1 -2
inch logs and add progressively more and larger logs to
subsequent fires, keeping the Air Control set to the fully
open position.
It is normal for a new fireplace insert to emit
odor and possibly smoke during the first few fires.
This is characteristic of the burn-off of residues from
the manufacturing process and the curing of painted
surfaces. Open a window near the fireplace insert to
provide plenty of fresh air to the room during this
"seasoning" period.
DO NOT OVER-FIRE THIS APPLIANCE. IF ANY PART
OF THE INSERT OR CHIMNEY GLOWS RED, 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.

ALWAYS WEAR STOVE GLOVES WHILE TENDING THE
FIRE.
NEVER ALLOW THE FIRE TO REST DIRECTLY ON THE
GLASS. KEEP THE LOGS SPACED AT LEAST ONE INCH
FROM THE GLASS TO ALLOW FOR PROPER AIR FLOW
WITHIN THE STOVE. AVOID STRIKING THE GLASS.
OPERATE THE INSERT ONLY WITH THE DOOR FULLY
CLOSED. OPERATION WITH THE DOOR PARTIALLY
OPEN MAY RESULT IN OVER-FIRING. IF THE DOOR
IS LEFT PARTIALLY OPEN, GAS AND FLAME MAY
BE DRAWN OUT OF THE STOVE CREATING SAFETY
