S'assurer que l'appareil fonctionne adé-
quatement une fois l'entretien terminé.
Always turn off gas to the pilot (millivolt
appliances) before cleaning. before re-
lighting, 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 vapors
and liquids.
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 venting unobstructed and
vent components are properly assembled and
not damaged).
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.
Clean Control Compartment -
Keep control
compartment clean by vacuuming or brushing
at least twice a year. More frequent cleaning may
be required due to excessive lint from carpet-
ing, bedding materials, etc. It is important that
control compartments, burners and circulating
air passageways of the appliance be kept clean.
Clean Logs And burner -
Carefully remove the
logs (use care when handling the fiber logs, as
they become quite fragile after curing). Vacuum
out any foreign matter (lint, carbon, etc). on
WARNING
Turn off gas and electrical power
to the fireplace and allow it to
cool before cleaning or servicing
the appliance.
LOGS, GLOWING EMbERS AND
vOLCANIC STONE PLACEMENT
WARNING
• DO NOT attempt to install the
logs until the appliance instal-
lation has been completed, the
gas line connected and tested
for leaks and the initial burner
operation has been checked
out.
• The size and position of the
log
set was engineered to give the
appliance a safe, reliable and
attractive flame pattern. Any
attempt to use a different log
set in the fireplace will void
the warranty and will result in
incomplete combustion, soot-
ing, and poor flame quality.
•
Logs get very hot and will
remain hot up to one hour
after gas supply is turned off.
Handle only when logs are
cool. Turn off all electricity to
the appliance before you install
grate, volcanic stone, embers
and logs.
•
This appliance is not designed
to burn wood. Any attempt to
do so could cause irreparable
damage to the appliance and
prove hazardous to your safety.
•
If logs are not installed
according to the log instal-
lation instructions, flame
impingement and improper
combustion could occur and
result in soot and/or exces-
sive production of carbon
monoxide (CO), a colorless,
odorless, toxic gas.
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
Page 24
for order-
ing information).
Re-Install Embers and Logs -
Carefully follow
placement instructions on
Pages 10 and 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 discon-
nection 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 fonc-
tionnement inadéquat et dangereux.
Inspect and clean all wire connections. Ensure
that there is no melting or damage. Inspection
should include:
• Terminals at the Valve
• OFF/ON Switch
• (Optional Control Switch) Remote Control
or Remote Wall Switch Kit
Inspect burner Flame and Pilot Flame
Appearance
Periodically do a visual check of the burner
flame and the pilot flame. Ensure that the burner
flame appearance resembles the flame shown
in
Figure 14 on Page 12
and as described in
flame Appearance and Sooting on
Page 12
.
Refer to
Figures 16 and 17
on
Page 13
for
more information about the pilot flame appear-
ance. Contact a qualified service technician at
once if any abnormal condition is observed.
Small Area Paint Touch-up
Only use a factory supplied paint kit for touch-
ups. Paint is available at your local Lennox
Hearth Products dealer. Never attempt to
paint a hot fireplace.
Do not attempt to repaint the appliance until
