CFM BC Series Homeowner's Manual page 8

To vary the burn rate, adjust the control to the desired
position in between these extremes; opening the
primary air control makes the unit burn hotter. Closing
the control slows the unit down. You may adjust to any
position you desire.
6. Operating Glass Door
WARNING: Use only glass doors approved by CFM
Corporation for use with your particular fireplace.
If your fireplace is equipped with glass doors, start the
fire and leave the doors fully open. AFTER the fire is
well started, then the doors may be closed. We rec-
ommend for the most efficient use of glass doors on
all models of CFM Corporation fireplaces, except for
models BFC, EWF and WMC Series, that doors must
be fully open when firing at a 'moderate' to 'hot' rate.
Firing at a 'low' to 'moderate' rate or allowing fire to die
out, doors should be closed. The BFC, EWF and WMC
Series fireplaces are designed for maximum heat out-
put with doors fully closed at all times.
NOTE: The BFC fireplace should be operated only with
the doors fully closed.

WARNING: FIREPLACES EQUIPPED WITH DOORS
SHOULD BE OPERATED WITH DOORS FULLY
OPEN OR DOORS FULLY CLOSED. IF DOORS ARE
LEFT PARTLY OPEN, GAS AND FLAME MAY BE
DRAWN OUT OF THE FIREPLACE OPENING CRE-
ATING RISKS OF BOTH FIRE AND SMOKE. Refer to
Figure 9 for correct door positions.
Do not close the glass doors on an excessively hot fire.
This could remove the temper from the glass, causing
it to crack into small pieces. The glass must be allowed
to warm slowly. The tempered glass in the doors will
withstand a gradual temperature rise to 550° F, which
is more than a normal fire will create. An excessively
hot fire can be created by such things as pitch laden
logs, very dry mill end lumber or large amounts of paper
or cardboard cartons. Keep the fire well back from the
doors and never let flames contact the glass.
Breakage may occur if the glass doors are mishandled.
Always use caution when operating the doors and do
not slam or force them into position.
