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 ) to the appliance. Never use galvanized or plastic pipe. Refer to the table below for suggested si zing of the gas supply line.

A periodic visual check of burner flames should be performed. The burner flame should appear as indi­cated on page 17 - Burner Flame Appearance.
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.
PAGE 16
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.
