CONTROLLING COMBUSTION AIR:

If the outside combustion air kit is not used, air may still be drawn directly into the fireplace through the lower louvres. Outside and inside air may be combined by pulling the outside air lever out as far as possible, and turning the lever 90° to its locking position. Figure 22.

Should you find a frost build up on the air control box or a draft from the fireplace, close the outside air lever when the fireplace is not in use.

Air control box is shipped with inside air cover plate in open position.

ACHIEVING PROPER VENTING ACTION

Draft is the force which moves air from the fireplace up through the chimney. The amount of draft in your chimney depends on the length of the chimney, local geography, nearby obstructions and other forces. Adjusting the draft control regulates the temperature. The draft can be ad- justed from a low burn rate with the handle at the bottom setting to a fast burn rate with the handle at the top setting. Figure 23. Inadequate draft may cause back-puffing into the room and may cause plugging of the chimney. Too much draft may cause an excessive temperature in the fireplace, glowing red fireplace parts or an uncontrollable burn which can all lead to a chimney fire or a permanent damage to the unit. Do not operate your fireplace for longer than 30 minutes with the draft control on 'HIGH' (fully open).

FUEL LOADING AND BURN CYCLE

WHEN LOADING THE FIREPLACE, ENSURE THAT THE FI- BRE REFRACTORY BAFFLE IS NOT LIFTED UP.

For maximum efficiency, when the fireplace is thoroughly hot, load it fully to the top of the door opening and burn at a medium low setting. The bricks will be nearly all white and the glass mostly clear. The whiteness of the bricks and the cleanness of the glass are good indicators of your operat- ing efficiency.

Not enough heat is produced when only one or two pieces of wood are burned. A minimum of three pieces are needed to encase a bed of coals that sustains the fire. Loosely stacked wood burns quicker than a tightly packed load.

Wood burns in cycles rather than giving a steady output of heat. It is best to plan these cycles around your household routine so that only enough coals are left to start the next load. In the evening, load your fireplace, at least, a half- hour before bed to ensure a good fire that is hot enough to close the draft control for an overnight burn.

Burn only dry seasoned wood. It produces more heat and less soot or creosote. Do not burn ocean beach wood. Its salt content can produce a metal eating acid. When refueling open the door slowly to prevent smoke spillage. Use a pair of long fireplace gloves when feeding the fire. Because these fireplaces burn at the front, they are clean and effi- cient, but they are also very hot and gloves are useful. Keep a small steel shovel nearby to use as a poker and to re- move ashes. Do not store wood within 3 feet (1m) of the fireplace.

FLASH FIRES: A flash fire is a small fire burned quickly when you don't need much heat. After your kindling has "caught", load at least 3 pieces of wood, stacked loosely. Burn with the draft control fully open or closed only slightly.

EXTENDED FIRE: Load your larger pieces of wood com- pactly, packed close enough to prevent the flames from penetrating it completely. After approximately 30 minutes, depending on the size of the load, close the draft control completely making sure that the fire is not extinguished.

DO NOT OVERFIRE THE FIREPLACE! Overfiring can occur by: a) burning large amounts of smaller wood pieces such as furniture scraps, skids or treated wood; b) vigorously burning large loads of wood with the draft control on "HIGH" (fully open) for long periods of time (one or two hours).
