The following procedures will help ensure that your
heater continues to perform safely and efficiently.
Firebox Cleaning and Inspection
Cleanliness is critical to correct operation of the
heater. The log set, burner, valve controls and air
circulation areas must all be kept free of dust and
unobstructed by debris. Inspect these areas before
each use and clean whenever accumulation is evi-
dent. Follow the simple procedure outlined below.
Frequent cleaning may be necessary in living environ-
ments subject to excessive carpet lint or pet hair. For
example, if you live with a dog that sheds continuously,
you will need to inspect the burner area frequently and
clean it as often as the accumulation requires. In ex-
treme conditions, it may be necessary to clean the
burner and log set monthly or bi-weekly.
This appliance should be inspected and thoroughly
cleaned annually by a qualified gas technician.
Cleaning Procedure
1. Turn the burner OFF and let the heater cool com-
pletely before cleaning.
2. Lift the Front plate up and then swing the bottom out
to disengage it from the heater shell. (Page 13, Fig.
19)
3. Remove the screen by lifting up and away from the
unit. Or, if so equipped, remove the glass panel by
rotating the two cams toward the front of the firebox.
Lift the panel up and off of the firebox frame. (Fig.
28)
4. Carefully inspect the log set for damage. Contact
your local dealer if any damage is evident. DO NOT
OPERATE THE HEATER WITH A DAMAGED OR
LOOSE LOG SET.
Use a soft-bristled brush vacuum cleaner attachment
to remove dust or debris from the log set, pilot and
burner. Use care as the log set is fragile.
5. Inspect the catalytic combustor at the top of the
firebox. Replace the combustor if any damage or
deterioration is evident.
6. Replace the screen or glass panel and the front
plate. DO NOT OPERATE THE HEATER WITH
THE SCREEN / GLASS PANEL OR FRONT PLATE
REMOVED.
Maintenance
Glass Replacement
If so equipped, do not operate this appliance with the
glass panel cracked, broken, or removed. Replace
damaged glass only with an approved CFM Specialty
Home Products ceramic glass panel. Follow the Clean-
ing Procedure instructions regarding parts removal.
Care of Cast Iron
An occasional dusting with a dry rag will help keep the
painted surfaces looking new. Use high-temperature
stove paints, available through your local dealer, to
touch-up areas as needed. Clean areas to be painted
with a wire brush and be sure to cover the log set,
burner and valve assembly. Apply the paint sparingly;
two light coats of paint will give better results than a
single heavy coat.
Porcelain enamel surfaces should be cleaned
with a soft, damp cloth. Do not use abrasive cleaning
agents. If necessary, use only a cleaning agent formu-
lated specifically for use on porcelain enamel surfaces.

tion warrants.
