N. Burning Guidelines
For maximum operating efficiency with the lowest
emissions, follow these operating procedures:
1. Regardless of desired heat output, when loading the
fireplace, burn your fireplace with the Slide Air Control
wide open (fully to the right) for a minimum of 5 to 15
minutes.
2. Regulate burn rate (heat output) by using the Slide Air
Control. See Figure 51.1 on page 51.
3. Heat output settings: Follow the burn rate instructions
listed below.
NOTE: To establish your settings, always begin with the
air control all the way to the left to STOP and then move
it to the right for your desired setting.

Maximum Heat
*These are approximate settings, and will vary with type of
wood or chimney draft.
NOTE: If reloading a bright, hot coal bed for longer (low)
burn time, setting the ACC may not be required.
NOTE: BURN DRY, WELL-SEASONED WOOD.
O. Burn Rates
HIGH - Maximum Heat: Fully open (slide air control
all the way to the right). It is important to do this when
reloading the fireplace. Failure to do this could result in
excessive emissions (smoke).
MEDIUM HIGH BURN RATE - 15,000 to 30,000 BTU:
After a wood load has been burning on high for 5 to 15
minutes, close the Slide Air Control to 1/2 in. - 1-1/2 in.
(13 mm-38 mm) distance open. (Move the handle to left
to stop and then to right for the proper setting).
MEDIUM - 10,000 - 15,000 BTU: After a wood load has
been burning on high for 5 to 15 minutes (longer for very
large pieces or wet wood), slide Slide Air Control left to
1/8 in. -1/2 in. (3 mm-13 mm) distance open. (Move
the handle to left to stop and then to right for the proper
setting).
LOW - Below 10,000 BTU: After a wood load has been
burning on high for 5 to 15 minutes (longer for very large
pieces or wet wood), gradually slide the Air Control left
to close down the air, making sure to maintain flames in
the fireplace. It is very important to maintain flames in
your fireplace during the first few hours of a low burn to
avoid excessive air pollution.

P. Opacity
This is the measure of how cleanly your fireplace is burn-
ing. Opacity is measured in percent; 100% opacity is when
an object is totally obscured by the smoke column from a
chimney, and 0% opacity means that no smoke column can
be seen. As you become familiar with your fireplace, you
should periodically check the opacity. This will allow you
to know how to burn your fireplace as nearly smoke-free
as possible (goal of 0% opacity).
WARNING
Fire Risk.
Keep combustible materials, gasoline and
other flammable vapors and liquids clear of
appliance.
• Do NOT store flammable materials in the appliance's
vicinity.
• Do NOT use gasoline, lantern fuel, kerosene, charcoal
lighter fluid or similar liquids to start or "freshen up" a fire
in this heater.
• Keep all such liquids well away from the heater while it is
in use.
• Combustible materials may ignite.
WARNING
Fire Risk.
Do NOT store wood:
• Closer than required clearances to com-
bustibles to appliance
• Within space required for loading or ash
removal.
Do NOT operate appliance:
• With appliance door open.
• With ash removal system door open.
WARNING
Fire Risk.
• Do NOT burn wet or green wood.
• Store wood in dry location.
• Stack wood so both ends are exposed to air.
Wet, unseasoned wood can cause accumulation
of creosote.
