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.
Before re-lighting the fireplace, refer
to the lighting instructions in this
manual. Instructions are also found on
pull-out panels located 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).
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.
Glass Cleaning
See Front Glass Enclosure Panel, Removal
and Installation on
Page 13
.
WARNING
Turn OFF gas and electrical
power to the fireplace and allow
it to cool before cleaning or
servicing the appliance.
MAINTENANCE
(See Maintenance Schedule,
Page 23
)
Refer to the maintenance schedule for
maintenance tasks, procedures, frequency
and by whom they should be performed.
Always verify proper operation of the
appliance after servicing.
NOTE: Clean glass after first two weeks
of operation (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 a
dry, soft towel as desired. Take care not to
scratch the glass surface.
WARNING: Do not use abrasive
cleaners on glass. Never clean the
glass when it is hot.
The viewing glass should be cleaned
periodically to remove any build-up caused
from 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.
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 & 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 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 carpeting, 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 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: Improperly positioned 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 18
for
ordering information).
Re-install Embers, Volcanic stone and Logs
Carefully follow placement instructions on
Pages 14 and 15
). All logs should fit onto
corresponding pins and/or log stoppers.
This will ensure a proper flame and
safe combustion.
NOTE: If installing the contemporary burner/
floor kit, skip this step and instead refer to
the instructions provided with the kit.
Inspect Wiring
Refer to wiring diagram on
Page 18
.
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.
Inspect and clean all wire connections.
Ensure there is no melting melting or other
damage. Inspection should include:
• Terminals at the valve
• Wall ON/REMOTE/OFF switch
Low Battery Power Detection
The life span of the remote control system
batteries depends on many factors:
• the quality of the batteries used
• the number of appliance ignitions
• etc.
When the batteries are low, the receiver will
emit two (2) beeps (low battery alert) when it
receives a command from the transmitter.
After the batteries are replaced, the
receiver will emit one (1) beep when it
receives a command from the transmitter.
See
"Initialization of the System"
in the
Installation Instructions (P/N 506023-16).
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
Figures 18 and 19
and as
described in Flame Appearance and Sooting
on
Page 16
. Refer to
Figure 20 on Page 17
for more information about the pilot flame
appearance. 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.
If the surface later becomes stained or
marred, it may be lightly sanded and touched
up with spray paint.
