INSTRUCTIONS
1) Always turn off the gas valve before cleaning.
For relighting, refer to lighting instructions.
Keep the burner and control compartment
clean by brushing and vacuuming at least
once a year. When cleaning the logs, use a
soft clean paint brush as the logs are fragile
and easily damaged.

cloth (never when unit is hot). Never use
an abrasive cleaner. The glass should be
cleaned with a gas fi replace glass cleaner.
The glass should be cleaned when it
starts looking cloudy.
3) The heater is fi nished in a heat resistant
paint and should only be refi nished with heat
resistant paint. Excalibur

Paint - Metallic Black #6309.
4) Make a periodic check of burner for proper
position and condition. Visually check the
fl ame of the burner periodically, making sure
the fl ames are steady; not lifting or fl oating.
If there is a problem, call a qualifi ed service
person.
5) The appliance and venting system must be
inspected before use, and at least annually,
by a qualifi ed fi eld service person, to ensure
that the fl ow of combustion and ventilation
air is not obstructed.

service technician to inspect the appliance
and to replace any part of the control system
and any gas control which has been under

7) Verify operation after servicing.
General Vent Maintenance
Conduct an inspection of the venting system
semi-annually. Recommended areas to inspect
as follows:
1) Check the Venting System for corrosion in
areas that are exposed to the elements.
These will appear as rust spots or
streaks, and in extreme cases, holes.
These components should be replaced
immediately.
2) Remove the Cap, and shine a fl ashlight
down the Vent. Remove any bird nests, or
other foreign material.
3) Check for evidences of excessive
condensation, such as water droplets forming
in the inner liner, and subsequently dripping
out the joints, Continuous condensation can
cause corrosion of caps, pipe, and fi ttings.
It may be caused by having excessive
lateral runs, too many elbows, and exterior
portions of the system being exposed to
cold weather.
4) Inspect joints, to verify that no pipe
sections or fi ttings have been disturbed,
and consequently loosened. Also check
mechanical supports such as Wall Straps,
or plumbers' tape for rigidity.
GOLD-PLATED DOOR
OR SURROUND
The 24 carat gold-plated fi nish on the surround
and door requires little maintenance, and need
only be cleaned with a damp cloth.
DO NOT use abrasive materials or chemical
cleaners, as they may harm the fi nish and void
the warranty. Clean any fi ngerprints off before
turning the unit on.
LOG REPLACEMENT
The unit should never be used with broken logs.
Turn off the gas valve and allow the unit to cool
before opening door and carefully remove the
logs. (The pilot light generates enough heat to
burn someone.) If for any reason a log should
need replacement, you must use the proper
replacement log. The position of these logs
must be as shown in the diagrams under Log
Installation.
Note: Improper positioning of logs may
create carbon build-up and will
severely alter the unit's performance
which is not covered under
warranty.
THERMOPILE /
THERMOCOUPLE
1) Open the bottom louvers.
2) Loosen the thermocouple or thermopile with
a 7/16" wrench.

nut from the valve with a 9mm wrench.
Disconnect thermopile by loosening 2
screws marked TP on the valve.
4) Drop the thermocouple or thermopile down
from the bracket and pull it out of the unit.
