Q. Burning Guidelines
For maximum operating effi ciency with the lowest
emissions, follow these operating procedures:
1. Regardless of desired heat output, when loading the
fi replace, burn your fi replace with the Combustion 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 Com-
bustion Air Control. See Figure 2.5 on page 15.
3. Heat output settings: Follow the burn rate instructions
listed below.

*These are approximate settings, and will vary with type of

HIGH - Maximum Heat:
Fully open (Combustin Air Control
all the way to the right). It is important to do this when reload-
ing the fi replace. 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 Combustion 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), Combustion 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 burn-
ing on high for 5 to 15 minutes (longer for very large pieces
or wet wood), gradually slide the Combustion Air Control
left to close down the air, making sure to maintain fl ames in
the fi replace. It is very important to maintain fl ames in your
fi replace during the fi rst few hours of a low burn to avoid
excessive air pollution.
R. Burn Rates
This is the measure of how cleanly your fi replace is burning.
Opacity is measured in percent; 100% opacity is when an ob-
ject 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 fi replace, you should peri-
odically check the opacity. This will allow you to know how
to burn your fi replace as nearly smoke-free as possible (goal
of 0% opacity).

P. Manual Timer Override
If timer is unintentionally engaged, push the Timer Over-
ride Lever to the left. This will disengage the timer and set
the Fireplace back to the low setting. Figure 2.6
