EXAMPLES OF VENTING INSTALLATION APPLICATIONS
Model: L30 BF-2 (B-Vent) Venting Requirements
Approved for vertical termination only.
Venting Configuration Requirements:
A minimum of 5 feet vertical pipe is required to vent the
appliance. Lengthy horizontal pipe runs require sufficient
length of vertical pipe to deliver adequate draft. Use the
table above as a guide in planning your installation. The
use of multiple 45° or 90° elbows should be compensated by providing a ddi tio nal vertical pipe run .
This appliance has a 4” B-Vent flue collar and may be
installed with listed B-Vent piping and components.
Refer to the pipe manufacturer’s installation instructions
for specific requirements for their product. Maintain
proper cle arances to com bustible m aterials as spec ified
by the pipe manufacturer. W henever vent pipe is run
horizontally, maintain a minimum 1/4” ri se per foot. Exterior B-Vent exhaust systems should be enclosed in a
chase to avoid rapid cooling of exhaust gases in the
vent. Suc h cooling c ould produce c ondensati on of flue
gases or ex haust gas spi llage. The use of a chase is
highly recommended in colder climates.

GAS SUPPLY HOOKUP
If using pipe other than black iron pipe see NFPA 54-National
Fire Protection Association / ANSI Z223.1-American National
Standards Institute; and local code for specific requirements
for the type of pipe used. Alternative 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, t o the flex line 3/8” female f lare. The
flex line can be routed to the gas supply through either
the pedestal bottom or through the rear pedestal cover
depending upon the orientat ion of the supply line. Som e
areas may have certain restrictions against the use of
flexible gas lin es. Chec k local co des. T he gas a pplia nce
control valve has a 3 /8” NPT fem ale type inlet for the gas
supply line, if hard plumbing is requir ed.
If the gas supply will b e routed to the appl iance from the
rear, the flexible g as line f or hook up is rea dil y acc ess ible.
If the gas supply will b e routed to the appliance through
the flooring, remove th e rear panel. Redirect the flex ible
gas line through the large hole in the c enter of the pedestal base for gas supply connection.
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 Associatio n / ANSI Z223.1-American N ational
Standards Institute; and loca l cod e.
Gas piping must not run in or throu gh air ducts, clothes
chutes, chimneys or gas vents, dum b waiters or elevator
shafts.
Piping should be sloped 1 / 4” per 15 feet (6mm per
4.6m) upward toward th e 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, approv ed shut-off valve m ust be installed
upstream of any conn ector so that the app liance may be
isolated to allow service, removal, and replacement
(within six feet of the applianc e per NFPA 54, or twelve
inches in some c odes). 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 pressures in excess of *1/2 psi (3.5 kPa).
PAGE 8
• 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 t o the gas supply line us ing the
correct fitting required to the shut-off valve.
Install a drip leg where condensates might accumulate. Sediment traps, lik e drips an d col lection t ees, ar e
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 )

becomes stained or marred, it may be lightly sanded
and touched up with spray paint (S ee Small Area PaintTouch-Up, page 16). Paint is available at your local
authorized Lennox Hearth Products dealer. Never attempt to paint a hot stove.
CIRCULATION BLOWER OPERATION
The speed of the cir culation blower is controlled us ing
the speed control rheostat ( see following i llustration) on
the left hand side of the control p anel. The b lower s ystem is designed with a variable spee d control allowing
an infinite range of blower settings to meet the customer’s needs. W ith the rotar y switch turned f ully CCW
3, the blower is off . Tur ning the s witch CW 2 will activate the blower at its max imum speed. Further rotation
of the switch in the CW direction will r educe the speed
of the blower. At ap proxim ately 270° of CW 2 rotation,
the switch provides a minimum setting for blower
speed.
Thermostatic feature: With the control switch in any
“ON” position, the circulation blower is designed to
automatically begin op eration approxim ately 12 m inutes
after lighting the m ain burner. The blower will turn off
approximately 15 m inutes after th e main burn er is shutoff.

PAGE 15
MAINTENANCE
Always Turn Off Gas Control Valve Before Cleaning. Annual Maintenance Should Only Be
Performed By A Qualified Service Technician:
LOG SET
Removing & Cleaning Logs - Carefully remove the logs
(removing top logs, then lifting front log out, then rear
log). Use care when handling the fiber logs, as they become quite fragile af ter curing. Use a sm all soft-bristled
brush (e.g., a nylon paint brush) to rem ove soot, dust or
debris that may hav e accumulated on the burner or log
set. Remove the logs and burner, and clean them outside the home in a location with plenty of f resh air ventilation. Avoid breat hing fine partic ulates of dust t hat may
be generated. See page 10, Installing Log Set for instructions on reinstalling logs.
Replacing Logs - If logs become dam aged by accident
or improper handling and need replacement, use only the
proper replacement logs from manufacturer, which can
be purchased from your local dealer. See page 20.
CLEANING BURNER
With the logs removed, vacuum out any foreign matter
(lint, carbon etc.) o n the burner . Be sure t he burner ports
are “open.”
CLEANING VALVE / AIR VENTURI
Clean all lint and dust build- up around the control valve
and air shutter on th e venturi. Inspect and clean with a
brush or wire the inl et of the venturi for an y spider webs
or lint accumulation.
CLEAN EXTERNAL SURFACES
External surfaces should be kept clean and dust removed form air inlets to the appli ance. The f low of com bustion and ventilation air must not be obs tructed. The
appliance must be kept clear and free from combustible
materials, gasoline and other flamm able vapors and liquids.
SMALL AREA PAINT TOUCH-UP
The stove body is painted with a quality high-temperature
stove paint. Use onl y model TSPK-C Stove Paint, C atalog # 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 b etween the painted and bare surfaces. Do not let the sa nd paper gum up with paint, as
this will cause scratches on the metal surface. If there
are any scratches, use 600 grit sand paper ins tead. 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 i n smooth even strokes to
blend.
See Break-In Period on page 13 for information on c ur ing
the paint.
INSPECT WIRING / CAUTIONS:
1) Label all wires prior t o disconnection when servicing
controls. Wiring errors can cause improper and dangerous operation.
2) Verif y proper oper a tio n after servic in g.
3) Inspect and clean all wire connections. Ensure that
there is no melting or damage from rodents. Inspection should include:
• Terminals at the valve
• On / Off switch
• Wall Thermostat / Remote Control (optional kits)
VENTING SYSTEM
A periodic examination of the venting system must be
performed to ensure tha t the f lo w of c om bus tion a ir is not
obstructed. We recommend that you have your gas appliance checked yearly by your independent Lennox
dealer.
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 abrasive cleaners on glass. The
viewing glass should be cleaned periodically. Exterior
glass may be cleaned with a glass cleaner as desired.
Interior glass - use s oap and water, or com mercial glas s
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.

MAINTENANCE
Always Turn Off Gas Control Valve Before Cleaning. Annual Maintenance Should Only Be
Performed By A Qualified Service Technician:
PERIODIC CHECK OF PILOT AND BURNER
FLAMES
Check the operation of the pilot and cycle the burner.
Visually check the flame of the burner m aking sure the
flames are steady; not lifting or floatin g. The flam e color
should be blue at the burner with yellow body and tops.
Cycle unit a minimum of 2 times
• Watch for smooth burner ignition and shut down.
• Burner: Check flame patterns.Ensure that burner
flame appearance does not vary greatly from diagram shown on this page.
• Pilot: Ensure pilot flame appearance does not vary
greatly from diagram shown below.
PILOT FLAME APPEARANCE
A proper pilot flame should consist of torch-like flame
issuing from the pi lot hood as shown in illust ration below.
Proper Pilot Appearance
BURNER FLAME APPEARANCE
A periodic visual check of the pilot and burner flames
should be perform ed. If either the pilot or burner flam e
do not show proper appearance or behavior, as outlined
here, consult a qualified gas appliance technician.
A proper burner flame is shown above. The burner
flame should have the following characteristics after
initial start-up (le t appliance burn 15 to 2 0 minutes pr ior
to accessing flame appearance):
• Excessive impingement (contact of flame with
logs) should not occur.
• Rear burner f lames should have yello wis h tips ; no
soot should form at burner flame tips.
• Flam es should not raise off of burner (no “lifting”
of flame).
Air Shu tte r Adju stm e nt
The flame can be adjusted to give t he proper flam e appearance and to pre vent sooting on the window or logs
by adjusting the position of the primary air shutter (located at the rear center inlet to the burner). The air
shutter should be posi tioned ap prox im ately 1/2 op en f or
Natural Gas and approx imately 3/4 open for LP Gas. .
See page 10, Burner Air Shutter.
NOTE: During periods of high nat ural gas dem and, the
gas supplier m ay add “make-up gases” to the pipeline.
This addition will change the c omposition of the supp ly
gas, and may cause a change in bur ner flame appear ance. You may also notic e soot formation on the logs
and viewing windows. Chec k with your gas supplier if
you suspect a change in the composition of your gas
supply.
