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

R. Burn Rates

HIGH - Maximum Heat: Fully open (Combustin Air Control all the way to the right). It is important to do this when reload- ing 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 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 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.

Q. 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 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.

Burn Rate	BTU / Hr	*Combustion Air Control
Low	Below 10,000	Slide LEFT to Stop
Medium	10,000 - 15,000	Stop to 1/8 in. -1/2 in. open
Medium High	15,000 - 30,000	Stop to 1/2 in. - 1-1/2 in. open
High	Maximum Heat	All the way to RIGHT

*These are approximate settings, and will vary with type of wood or chimney draft.

S. Opacity

This is the measure of how cleanly your fireplace 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 fireplace, you should peri- odically check the opacity. This will allow you to know how to burn your fireplace as nearly smoke-free as possible (goal of 0% opacity).
