change in the flame pattern. The flames will be slow and intermittent and may appear dirty if the wood is too wet i.e., a moisture content of 20% and more.
During the Low Combustion Burn Mode, creosote may accumulate on the glass doors. Low combustion burning should only be used after the firebox has been allowed to reach a hot operating temperature i.e., the air combustion damper has been fully open to produce a hot fire for about an hour. Low combustion can be used at night in order to reduce the heat output and to prolong the burn. The loading time will be between six to twelve hours.

REFUELING FOR OPTIMUM PERFORMANCE
The Inglenook Fireplace performance will be greatly enhanced if the operator will ensure the combustion air damper is fully opened after refueling. If this process is followed, the firebox and chimney system will return to optimum operating temperature in the shortest period of time. Combustion efficiency is directly affected by firebox temperature and following the above stated process will ensure maximum efficiency of your Inglenook Fireplace. The upper part of the Inglenook firebox temperature should exceed 1,200 degrees Fahrenheit or higher in order to achieve maximum operating efficiency. To obtain this firebox temperature after reloading of wood, the Inglenook should be operated with the combustion air damper fully opened for a minimum of 15 to 30 minutes. Again, the time will vary depending on the room heat, moisture content of the wood and the type of wood being burnt. Once the Inglenook has reached a proper operating temperature, the combustion air damper can be gradually closed. A good indication that the proper temperature has been reached is when a flame can be seen at the top of the firebox. This upper fire indicates excellent combustion and will ensure cleaner glass, less creosoting, greater efficiency, and the greatest warmth and viewing pleasure for your family to enjoy.
SMOKING - CAUSES
In order to reduce the problematic issue of smoke escaping from the Inglenook Fireplace when opening the firebox doors, always ensure that the combustion air damper is in the fully open position before the doors are opened. CAUTION: ALWAYS open all fireplace doors very slowly. This will ensure that the fireplace is drafting through the fresh air intake and the chimney system rather than using your house as a source for air or the expulsion of air. Your fireplace has been designed and tested to provide smoke free operation. Occasionally, there may be a small amount of smoking due to the fact that the chimney system has not reached proper operating temperature. A warm chimney system ensures maximum draft efficiency for the firebox. If the fireplace continues to smoke it is probably for one of the following reasons:
1. Doors Partly Open
Always operate the Inglenook with the front doors fully open or fully closed. If the doors are operated fully open, the optional screen kit MUST be installed for safety reasons.
