VENT RESTRICTOR RING INSTALLATION
Recommended Restrictor Ring Placement For Optimum Stove Performance
Guideline for Installing Flue Restrictor
Ring in Co-Axial Direct-Vent Pipe
If the total vertical venting is 16 feet or
higher, installation of 1 restrictor ring is rec-
ommended to improve the performance and
flame asthetics of the appliance. Install the
restrictor ring between the appliance outlet /
inlet collar and the first section of pipe. De-
pending upon the vent configuration and
other variables, it may be necessary to adjust
the quantity and position of the restrictor
ring(s) to ensure proper operation of the ap-
pliance. Be advised, product performance
can be affected due to numerous factors
which affect exhaust flow and air delivery,
such as – gas BTU value, vent configura-
tion, ambient temperature, altitude, etc.
Symptoms for Lack of Combustion Air
Remove restrictor ring(s) to increase com-
bustion air delivery if the following symptoms
are present (first confirm input is correct, pri-
mary air shutter is properly adjusted, venting
system connections are secure and not
blocked):
♦ Flame appears yellow with black tips.
♦ Floating Flames (lazy, ill-defined, quiet,
may roll).
♦ Sooting.
♦ Pilot becomes yellow and appliance
shuts down.
Symptoms - Excessive Combustion Air
Install one or more restrictor rings to reduce
combustion air delivery if the following symp-
toms are present:
♦ Low Flame.
♦ Pilot pulls and appliance shuts down.
♦ Pilot flame ghosts
16 Feet or Higher,
Install Restrictor
Ring
If total vertical venting is
16 feet or higher, install 1
restrictor ring (included)
between the appliance
outlet / inlet collar and
first section of pipe.

GAS SUPPLY HOOKUP
If using pipe other than black iron pipe see NFPA 54-National Fire Protec-
tion Association / ANSI Z223.1-American National Standards Institute;
and local code for specific requirements for the type of pipe used. Alter-
native gas piping systems such as CSST may be used subject to local
code and proper sizing.
This appliance is equipped with a flexible gas line and fitting for
a gas supply line connection. Connection can be made using
either the 3/8” NPT male fitting or, by removing the fitting, to the
flex line 3/8” female flare. The flex line can be routed to the gas
supply through either the pedestal bottom or through the rear
pedestal cover depending upon the orientation of the supply line.
Some areas may have certain restrictions against the use of
flexible gas lines. Check local codes. The gas appliance control
valve has a 3/8” NPT female type inlet for the gas supply line, if
hard plumbing is required.
If the gas supply will be routed to the appliance from the rear,
the flexible gas line for hookup is readily accessible. If the gas
supply will be routed to the appliance through the flooring, re-
move the rear panel. Redirect the flexible gas line through the
large hole in the center of the pedestal base for gas supply con-
nection.
A gas supply line must be run to the appliance by a qualified
professional. The plumbing of the gas line must comply with
National Standards; NFPA 54-National Fire Protection Associa-
tion / ANSI Z223.1-American National Standards Institute; and
local code.
Gas piping must not run in or through air ducts, clothes chutes,
chimneys or gas vents, dumb waiters or elevator shafts.
Piping should be sloped 1/4” per 15 feet (6mm per 4.6m) up-
ward toward the meter from the appliance. The piping must be
supported at proper intervals every 8 to 10 ft. (2.4m to 3.1m)
using suitable hangers or straps.
The gas supply line must be purged of air before it is connected
to the appliance.
An accessible, approved shut-off valve must be installed up-
stream of any connector so that the appliance may be isolated to
allow service, removal, and replacement (within six feet of the
appliance per NFPA 54, or twelve inches in some codes). A shut-
off valve is provided with this appliance.
IMPORTANT: In case emergency shut-off is required, shut off
main manual gas valve and disconnect main power to appliance.
These devices should be properly labeled by the installer.
PRESSURE TESTING:
• The appliance main gas valve must be disconnected from the gas supply
piping system during any pressure testing of that system at test pres-
sures in excess of *1/2 psi (3.5 kPa).
• The appliance must be isolated from the gas supply piping system
by closing its individual manual shut-off valve during any pressure
testing of the gas supply piping system at test pressures equal to
or less than *1/2 psi (3.5 kPa).
Make the connection to the gas supply line using the correct
fitting required to the shut-off valve.
Install a drip leg where condensates might accumulate.
Sediment traps, like drips and collection tees, are required to
be installed. Traps collect moisture and intercept and hold
foreign objects which might block orifices and valves. A drip
leg should be installed in vertical pipe runs to the appliance.
Supply Line Size Requirements
The proper gas line diameter must be used to run from the
supply regulator (at the gas company meter) to the appli-
ance. Never use galvanized or plastic pipe. Refer to the ta-
ble below for suggested sizing of the gas supply line.

150-200 3/4 1/2
Use an approved pipe sealant compound for NPT fittings.
After all pipe connections are made, apply normal gas line
pressure: 7.0” W.C. for natural gas; 11.0” W.C. for LP gas
(propane) and use an approved leak detection solution to
test for the tightness of each pipe connection joint.
IMPORTANT: All connections must be checked for leaks with a leak
detector or soapy water solution. Never check for gas leakage with an
open flame!

“BREAK-IN” PERIOD
The finish on this appliance is a high temperature paint that
requires time and temperature to completely cure. The curing
process will take 2 or 3 burns (heat up and cool down peri-
ods). We recommend that you ventilate the house during the
initial burns. The paint emits non-toxic odors during this proc-
ess.
KEEP YOUR HOUSE WELL VENTILATED DURING THE CURING
PROCESS TO PREVENT ACTIVATION OF YOUR HOME SMOKE
DETECTOR.
Do not turn on a blower during the break-in period. Do not
place anything on the stove surface until the paint is com-
pletely cured. Do not attempt to repaint the stove until the
paint is completely cured. If the surface later becomes stained
or marred, it may be lightly sanded and touched up with spray
paint (See Small Area Paint Touch-Up, page 19). Paint is avail-
able at your local authorized Lennox Hearth Products dealer.
Never attempt to paint a hot stove.
COMBUSTION CHAMBER RELIEF DOORS
This appliance is equipped with 3 relief doors (one behind the
back panel, and one on each side, behind side panels) in case
of delayed ignition blow back. If one or more relief doors open,
inspect for gasket damage. If necessary, replace with factory
supplied gasket only. Confirm relief doors are closed and
properly seated.
CIRCULATION BLOWER OPERATION
The speed of the circulation blower is controlled using the
speed control rheostat (see following illustration) on the left
hand side of the control panel. The blower system is designed
with a variable speed control allowing an infinite range of
blower settings to meet the customer’s needs. With the rotary
switch turned fully CCW 4, the blower is off. Turning the
switch CW 3will activate the blower at its maximum speed.
Further rotation of the switch in the CW direction will reduce
the speed of the blower. At approximately 270° of CW 3rota-
tion, the switch provides a minimum setting for blower speed.
Thermostatic feature: With the control switch in any “ON” po-
sition, the circulation blower is designed to automatically begin
operation approximately 12 minutes after lighting the main
burner. The blower will turn off approximately 15 minutes
after the main burner is shut-off.

PROPANE CONVERSION PROCEDURE
(Only required if Propane gas is used)
This appliance is designed to operate on natural gas, or propane
(LP). It is factory set for use with natural gas and requires field
conversion for use with propane. The use of other fuels or com-
bination of fuels will degrade the performance of this system
and may be dangerous.
When converting to Propane Gas (LP), it may be necessary to
install (as a minimum) 3 feet of vertical pipe from the appli-
ance prior to an offset to ensure optimum product performance.
This may be necessary due to variations in vent configuration
and other numerous factors which affect exhaust flow and air
delivery such as BTU value, ambient temperature, wind condi-
tions, altitude, etc.
The conversion kit provided with this appliance contains com-
ponents required to convert this appliance from use with natural
gas to use with propane (LP) Gas. All of the components in the
propane conversion kit must be installed in order for the appli-
ance to operate safely on propane.

Qualified Service Technician:
PAGE 20
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 12, 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 23.
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.
If the vent-air intake system is disassembled for any reason, the
service technician should follow vent manufactures 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 16 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.
