LOG SET
Removing & Cleaning Logs - Carefully remove the logs (remov-
ing top logs, then lifting front log out, then rear log). Use care
when handling the fiber logs, as they become quite fragile after
curing. Use a small soft-bristled brush (e.g., a nylon paint
brush) to remove soot, dust or debris that may have accumu-
lated on the burner or log set. Remove the logs and burner, and
clean them outside the home in a location with plenty of fresh
air ventilation. Avoid breathing fine particulates of dust that
may be generated. See page 14, Installing Log Set for instruc-
tions on reinstalling logs.
Replacing Logs - If logs become damaged by accident or im-
proper handling and need replacement, use only the proper re-
placement logs from manufacturer, which can be purchased
from your local dealer. See Page 25.
CLEANING BURNER
With the logs removed, vacuum out any foreign matter (lint,
carbon etc.) on the burner. Be sure the burner ports are “open.”
CLEANING VALVE / AIR VENTURI
Clean all lint and dust build-up around the control valve and air
shutter on the venturi. Inspect and clean with a brush or wire
the inlet of the venturi for any spider webs or lint accumulation.
INSPECT WIRING / CAUTIONS:
1) Label all wires prior to disconnection when servicing con-
trols. Wiring errors can cause improper and dangerous op-
eration.
2) Verify proper operation after servicing.
3) Inspect and clean all wire connections. Ensure that there is
no melting or damage from rodents. Inspection should in-
clude:
• Terminals at the valve
• On / Off switch
• Wall Thermostat / Remote Control (optional kits)
VENTING SYSTEM
A periodic examination of the venting system must be per-
formed to ensure that the flow of combustion and ventilation air
is not obstructed (outlet and inlet is open and free from block-
age). We recommend that you have your gas appliance checked
yearly by your independent Lennox dealer.
(Model L20 DVF-2) If the vent-air intake system is disassembled
for any reason, the service technician should follow vent manu-
factures instructions for proper reassembly and sealing of the
vent-air intake system.
IMPORTANT – APPLIANCES INSTALLED USING SIMPSON DURA-VENT
BRAND PIPE MUST SEAL ALL JOINTS WITH MILL-PAC BLACK, HIGH
TEMPERATURE SEALANT.
CLEAN EXTERNAL SURFACES
External surfaces should be kept clean and dust removed form
air inlets to the appliance. The flow of combustion and ventila-
tion air must not be obstructed. The appliance must be kept
clear and free from combustible materials, gasoline and other
flammable vapors and liquids.
SMALL AREA PAINT TOUCH-UP
The stove body is painted with a quality high-temperature stove
paint. Use only model TSPK-C Stove Paint, Catalog # 19L92. Do
not touch-up this appliance with any other paint.
Using one small piece of 320 grit sand paper and lightly sand
the blemish so that the edges are “feathered” or smooth to the
touch between the painted and bare surfaces. Do not let the
sand paper gum up with paint, as this will cause scratches on
the metal surface. If there are any scratches, use 600 grit sand-
paper instead. Mask off surfaces you do not want painted. Paint
lightly over the bare surface first as this will act as an undercoat.
Then paint over a larger area in smooth even strokes to blend.
See Break-In Period on page 17 for information on curing the
paint.
CLEANING GLASS
The window on the gas appliance is made from a clear ceramic
material and may be cleaned when cool with any non-abrasive
product designed for use on glass windows. Do not use abra-
sive cleaners on glass. The viewing glass should be cleaned
periodically. Exterior glass may be cleaned with a glass cleaner
as desired. Interior glass - use soap and water, or commercial
glass cleaner recommended for stove glass.
Note: Each time the appliance is lit, it may cause condensation
and fog on the glass. This condensation and fog will disappear
in a few minutes.
CLEANING BLOWER INTAKE
The blower air intake requires cleaning at least once a year to
remove lint, dust, etc. If there are pets in the dwelling, the intake
should be cleaned at least twice a year.
