Refer to the
Maintenance Schedule
on
Page 61
for maintenance tasks, procedures, frequency, and a listing of by
whom the tasks should be performed. Always verify proper fireplace operation 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.
Always turn OFF gas before cleaning. Before relighting, refer to the lighting instructions in this manual.
Instructions are also found on a pull-out panel located in the control compartment.
Always keep the appliance area clear and free from combustible materials, gasoline and other flammable liquids.
NOTE:
Prior to the first use of the fireplace and each burn season and periodically during the burn season, inspect the
horizontal termination for debris such as bird nests, leaves, paper or branches. Remove any items from the surfaces of the
termination prior to use. Also be aware of shrubs and plantings that may encroach on the termination.
Inspecting the venting system
The fireplace 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.
The homeowner must contact a qualified service technician at once if any abnormal condition is observed.
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.
NOTE:
Prior to the first use of the fireplace and each burn season and periodically during the burn season, inspect
the horizontal termination for debris such as bird nests, leaves, paper or branches. Remove any items from the
surfaces of the termination prior to use. Also be aware of shrubs and plantings that may encroach on the termination.

Cleaning the glass door
WARNING
Do not use abrasive cleaners on glass. Never clean the glass when it is hot.
Clean the glass during the
Burn-in Period
, and then only when necessary and when the fireplace is cool. Wipe the
surface with a clean, dampened, soft cloth. Follow with a dry, soft towel as desired. Take care not to scratch the
glass surface. Periodically, remove any build-up caused by the following:
• 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.
Clean the glass two or three times each heating season, depending on the circumstances present. The following
cleaning solutions are approved for use:
• Non-ammonia based glass cleaner
• Gas fireplace/stove glass cleaner
