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.

Burn Rate	BTU / Hr	*Slide 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.

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.
