Heatiator C40 Automatic Combustion Control ACC, Final stage, Slide Air Control Slide Left to Stop

Final stage:

The final stage of burning is the charcoal stage. This occurs when the flammable gases have been mostly burned and only charcoal remains. This is a naturally clean portion of the burn. The coals burn with hot blue flames.

It is very important to reload your fireplace while enough lively hot coals remain in order to provide the amount of heat needed to dry and rekindle the next load of wood. It is best to open the air control for a short while before reloading. This livens up the coalbed. Open door slowly so that ash or smoke does not exit fireplace through opening. You should also break up any large chunks and distribute the coals so that the new wood is laid evenly on hot coals.

Fireplace operation does require air. Do not take air from other fuel burning appliances which can result in improper venting (smoking) or air dilution. Always provide adequate makeup air.

O. Automatic Combustion Control (ACC)

IMPORTANT! As you move the Combustion Air Control to the RIGHT, you will feel resistance about three-fourths of the way. You must move past that resistance approxi- mately 3/4 in. (19mm) to fully engage the Automatic Combustion Control (ACC) sytstem.

With the Automatic Combustion Control system that is on this fireplace, you can set the fireplace to high (slide the Combus- tion Air Control all the way to the right), start the fire, and then move the Combustion Air Control to the desired burn level. The fireplace will automatically go to that level once the fire is fully established. This allows for less interaction with the fire by the homeowner and more efficient use of fuel while maintaining the desired heat output.

After the fireplace has been in operation for a period of time, and is warmed up; you may prefer to not activate the ACC when reloading fuel. if you do not slide the Combustion Air Control all the way to the right, the ACC will not be activated.

ACC OVERRIDE

The lever located to the left of the Combustion Air Control is the ACC OVERRIDE and may be used to override the setting of the Combustion Air Control. If the ACC has been activated and burn rate needs to be slowed, move the lever to the LEFT and position Combustion Air Control at the preferred setting. To close the air supply for an over fire situatution or to slow the burn rate down immediately, slide the lever to the LEFT and also slide the Combustion Air Control all the way to the left.

NOTICE: If reloading a bright, hot coal bed for longer (low) burn time, setting the ACC may not be required. Burn Dry, well seasoned wood.

NOTICE: 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.
