MAINTENANCE
(See Maintenance Schedule, Page 22)
Refer to the maintenance schedule for maintenance
tasks, procedures, periodicity and by whom they
should be performed. Always verify proper operation of the appliance after servicing.
WARNING: Turn off gas and electrical power to the fireplace and
allow it to cool before cleaning or
servicing the appliance.
CAUTION: Wear gloves and safety
glasses for protection while doing
required maintenance.
Verify proper operation after servicing.
S'assurer que l'appareil fonctionne adéquatement une fois l'entretien terminé.
Before re-lighting the fireplace, refer to the
lighting instructions in this manual. Instructions are also found on pull-out panels
located below the glass door in the control
compartment.
Inspect Venting System
The appliance and venting system should be
thoroughly inspected before initial use and
at least annually by a qualified service technician (inspection should include ensuring that
exhaust or intake passages are unobstructed
and vent components are properly assembled
and not damaged).
If the venting system is disassembled for any
reason, a qualified service technician should
follow vent installation instructions for proper
reassembly and proper sealing of the venting
system components. However, more frequent
periodic inspections and cleanings should be
performed by the homeowner.
Cleaning Glass
(see Front Glass Enclosure Panel, Removal and
Installation on Page 7 )
Note: Clean glass after first two weeks of opera-
tion (after Burn-In period is over) and then only
when necessary and when the fireplace is cool.
Wipe surface with clean, dampened, soft cloth.
Follow with dry, soft towel as desired. Take care
not to scratch the glass surface.
The viewing glass should be cleaned periodically to remove any build-up caused from the
following:
IMPORTANT: Do not use abrasive cleaners on glass. Never clean the glass when
it is hot.
• During start-up, it is normal for condensation to form on the inside of the glass (this
condensation and fog will usually disappear in
a few minutes). The moisture can cause lint,
dust and other airborne particles to cling to the
glass surface.
• Initial curing of the high temperature paint
and burning off of lubricants used in the
manufacturing process may result in a film
on the glass.
• A white coating may form on the glass as a result
of impurities and minerals in the fuel.
It is recommended that the glass be cleaned
two or three times during each heating season,
depending on the circumstances present. The
following cleaning solutions are approved for
use to clean glass:
• Non-ammonia based household cleaner
• 50%-50% mix of white vinegar and
water
• Gas fireplace/stove glass cleaner
Inspect Glass Gasket - Visually inspect the
gasket on the backside of the glass enclosure
panels. The gasket surface must be clean, free
of irregularities and seated firmly.
Clean Logs And Burner
Carefully remove the logs (use care when han
dling the fiber logs, as they become quite fragile
after curing). Vacuum out any foreign matter
(lint, carbon, etc). on the burner. Ensure the
burner ports are “open.” Remove any carbon
deposits from the under side of the logs using
a vacuum cleaner, or a soft bristled brush (i.e.
paint brush).
Note: Improper positioning of logs can create
carbon build-up and will alter the performance
of the appliance.
Replacing Logs -
If the logs become damaged by accident or
improper handling and need replacement,
use only the proper replacement logs from
manufacturer (see Pages 25 and 26 for order-
ing information).
Re-Install Embers and Logs - Carefully follow
placement instructions on Pages 8 thru 11.
All logs should fit onto corresponding pins
and/or log stoppers. This will ensure a proper
flame and safe combustion.
Inspect Wiring
Refer to wiring diagrams on Page 14
.
CAUTION: Label all wires prior to disconnection when servicing controls. Wiring
errors can cause improper and dangerous
operation. Verify proper operation after
servicing.
ATTENTION: Au moment de l'entretien
des commandes, étiquetez tous les fils
avant de les débrancher. Des erreurs
de cáblage peuvent entraîner un fonctionnement inadéquat et dangereux.

4. Placement of Glowing Embers -
Separate the Embers (rockwool) into pieces
about the size of a quarter (see Figure 7 ).
Keep the pieces fluffed up, not matted. Distribute these pieces over the surface of the
burner, as shown in Figures 8 and 9. Do not
use more than is necessary. Ensure that the
main burner slots remain uncovered by the
ember material. Position the embers on the
small holes of the ember bed area.
Note: This appliance is provided with enough
Glowing Embers for several applications, do
not use all that is in a new bag at one time.
For best glowing effect, replace the ember
material annually.

All logs that have locating notches or slots to
help ensure that they are properly positioned.
All top logs that rest on lower logs, do so over
notches, indents or nubs. Proper log placement
is critical to prevent sooting. Logs should be
placed in the gaps between the flame peaks and
should be positioned so they do not impinge
the flames.
