FIREPLACE DOOR OPERATION
BASIC DOOR OPERATION
Once properly installed, a Country Flame Fireplace Door System has two operating parts:
(a) the door system and (b) the combustion air control system. All Country Flame
fireplace door systems come with double doors (left and right.) The left door is locked in
place by the right door. This means that the handle on the left door is fixed. If a large
amount of turning pressure is applied to the left door handle, DAMAGE will occur. The left door
handle is to be used to pull open or push shut the left door. The right door handle must be turned
counterclockwise about 90 degrees and then pulled open. To close and lock the right door, first
close the left door and then close the right door. The right door can now be locked by turning the
handle clockwise about 90 degrees. Try operating the doors several times before a fire is started
in order to work with cool handles and doors. The doors are large to allow easy fuel loading and
to provide a large viewing area of the burning fire. Door systems should be operated only in the
fully open or fully closed position. If doors are open, an optional fire screen should be installed
for safety purposes.
DOOR AIR CONTROL
Fireplace door systems are installed to improve the efficiency of the fireplace (use less
wood per unit of heat output), provide additional safety, and to add value to the home.
Each Country Flame fireplace door system comes standard with combustion air controls
built into the door. No matter which set of Country Flame doors have been purchased, the
combustion air control is conveniently located just below the two front doors. FIGURE 4 shows
just the control mechanisms. On all 500 doors, a slider controls the amount of combustion air
entering a fireplace’s firebox. By moving this control sideways (left or right) the amount of
combustion air is decreased or increased. On all 400 doors, two cast knobs control the amount of
combustion air. By turning the knobs clockwise, the amount of air is reduced and by turning the
knobs counterclockwise, the amount of air is increased.
WARNING: When in use, the
fireplace’s combustion air controls can be extremely hot. To adjust the combustion air control
after a fire has been started, it is strongly recommended to always wear approved fireplace
gloves. Experiment with these controls before starting a fire to ensure a complete understanding
of their operation. These air controls are critical to maintaining correct wood fuel burn rates.
