READ THIS MANUAL IN ITS ENTIRETY AND UNDERSTAND THESE RULES TO FOLLOW FOR SAFETY

WARNING

Improper installation, adjustment, alteration, service or maintenance can cause injury or property damage. Refer to this manual. For assistance or additional information consult a qualiﬁed installer or service agency.

WARNING

Do not attempt to alter or modify the construction of the appliance or its components. Any modiﬁcation or alteration may void the warranty, certiﬁcation and listings of this unit.

1. DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE.

2. Do not connect this appliance to air ducts or any air distribution system.

3. DO NOT INSTALL A FLUE DAMPER IN THE EXHAUST VENTING SYSTEM OF THIS UNIT.

4. Do not use class B venting intended for gas appliances as a chimney or connector pipe on a pellet-ﬁred appliance.

5. The minimum clearances must be maintained for all combustible surfaces and materials including; furniture, carpet, drapes, clothing, wood, papers, etc. Do not store combustibles within this clearance space (see Clearances on Page 5).

6. INSTALLATION DISCLAIMER - It is imperative that the exhaust venting system be installed correctly and sealed gas-tight (not allowing exhaust to leak). Follow the vent manufacturer's instructions for proper installation. Since Lennox Hearth Products has no control over the installation of your stove, Lennox Hearth Products grants no warranty, implied or stated for the installation or maintenance of your stove, and assumes no responsibility for any consequential damage(s).

7. Burning any kind of fuel consumes oxygen. If outside air is not ducted to the appliance, ensure that there is an adequate source of fresh air available to the room where the appliance is installed.

8. The appliance will not operate using natural draft, nor without a power source for the blower and fuel feeding systems.

9. Never use gasoline, gasoline-type lantern fuel, kerosene, charcoal lighter ﬂuid, or similar liquids to start or “freshen up” a ﬁre in this heater. Keep all such liquids well away from the heater while it is in use.

10. The authority having jurisdiction such as municipal building department, ﬁre department, ﬁre prevention bureau, etc. should be consulted before installation to determine the need to obtain a permit.

11. APPROVED FUEL: This appliance is designed speciﬁcally for use only with pelletized wood pellets or a mixture of up to 50% corn mixed with a minimum of 50% pelletized wood pellets. This mixture of wood pellets and corn should be evenly pre-mixed before being placed in the units hopper.

This appliance is designed and approved for the burning of wood residue pellets with up to 3% ash content. This appliance is NOT approved to burn cardboard, nut hulls, cherry pits, etc. regardless if it is in pellet form. Failure to comply with this restriction will void all warranties and the safety listing of the stove. Consult with your Lennox Hearth Products dealer for more information on approved pellet fuels.

12. CONTINUOUS OPERATION: When operated correctly, this appliance cannot be overﬁred. Continuous operation at a maximum burn can, however, shorten the life of the electrical components (blowers, motors, and electronic controls), and is not recommended. Typical approved operation would include running at the low to mid range setting with occasional running on the maximum setting during the coldest periods of the winter. DO NOT OVER-FIRE THIS STOVE. Follow all instructions regarding the proper use of this stove.

13.CAUTION: NEVER PUT FINGERS NEAR AUGER. This appliance is equipped with a hopper lid switch, which is designed to stop the auger when the hopper lid is opened. NEVER DISCONNECT

OR BYPASSED THIS SWITCH FOR ANY REASON. Pellet fuel is fed

to the Burn-pot by a screw auger. This auger is driven by a high torque motor. The auger is capable of causing serious harm to ﬁngers. Keep pellets in the hopper at all times and keep ﬁngers away from auger. The auger can start and stop automatically at any time while the stove is running.

14. CAUTION: HOT WHILE IN OPERATION. An appliance hot enough to warm your home can severely burn anyone touching it. Keep children, pets, clothing and furniture away. Contact may cause skin burns. Do not let children touch the appliance. Train them to stay a safe distance from the appliance.

15. FLY ASH BUILD-UP: For all wood pellet fuel-burning heaters, the combustion gases will contain small particles of ﬂy-ash. This will vary due to the ash content of the fuel being burned. Over time, the ﬂy-ash will collect in the exhaust venting system and restrict the ﬂow of the ﬂue gases. The exhaust venting system should be inspected regularly and cleaned as necessary.

16. SOOT FORMATION: Incomplete combustion, such as occurs during startup, shutdown, or incorrect operation of the room heater will lead to some soot formation which will collect in the exhaust venting system. A precautionary inspection on a regular basis is advisable to determine the necessity of cleaning. The exhaust venting system should be inspected regularly and cleaned as necessary.

17. DISPOSAL OF ASHES: Ashes should be placed in a metal container with a tight-ﬁtting lid. The closed container of ashes should be placed on a noncombustible ﬂoor or on the ground, well away from all combustible materials, pending ﬁnal disposal. If the ashes are disposed of by burial in soil or otherwise locally dispersed, they should be retained in the closed container until all cinders have been thoroughly cooled.

18. The instructions must be strictly adhered to. Do not use makeshift methods or compromise in the installation.

19. Do not abuse the door glass by striking, slamming or similar trauma. Do not operate the stove with the glass removed, cracked or broken.

CAUTION

These appliances are very heavy. The use of a heavy duty escalara (stair step hand truck) is recommended for lifting the appliance.

WARNING

Electrical grounding instructions: This appliance is equipped with a three-prong (grounding) plug for your protection against shock hazard and should be plugged directly into a properly grounded three-prong receptacle. Do not cut or remove the grounding prong from this plug. Do not route power cord under or in front of appliance.

2. Local amendments

3. Is a permit required - cost. You may wish to contact your insurance company to ask if they require this.

4. If outside combustion air is required

5. Rooms where the installation is not allowed

Surge Protectors

A surge protector is recommended to ensure the stove’s electrical components are not damaged due to a surge in the electrical supply. Only high quality protectors should be used - low quality protectors do not provide the protection needed.

Smoke Detectors

Since there are always several potential sources of ﬁre in any home, we recommend installing smoke detectors. If possible, install the smoke detector in a hallway adjacent to the room (to reduce the possibility of occasional false activation from the heat produced by these appliances). If your local code requires a smoke detector be installed within the same room, you must follow the requirements of your local code. Check with your local building department for requirements in your area.

Installation / Maintenance Standards

National Fire Protection Association – The primary NFPA standard that refers to installation and maintenance of pellet stoves and venting is NFPA 211 – Latest Edition: Chimneys, Fireplaces, Vents, and Solid Fuel appliances.

SELECTING A LOCATION

The design of your home and where you place your stove will determine its value as a source of heat. This type of appliance depends primarily on air circulation (convection) to disperse its heat, and therefore, a central location is often best. There are other practical considerations, which must be considered before a ﬁnal selection of locations is made. Some of which includes:

NEGATIVE PRESSURE WARNING

This appliance is not designed to be operated in a negative pressure. Very airtight homes with large kitchen exhaust fans, or homes with furnace cold air returns located in close proximity to the stove may create negative pressure in the same room as the heating appliance. This can create dangerous condition, drawing combustion by-products into the home. Be sure your home has adequate makeup air to eliminate negative pressures caused by the above-mentioned sources. Outside air connected to the appliance probably will not resolve such a problem as the stove is not the source of negative pressure. Lennox Hearth Products accepts no liability for damages resulting from negative pressures described here.

Ventilation Requirements - Provide adequate air for combustion. The fresh air requirements of this appliance must be met within the space where it will be installed. Ventilation is essential when using a solid-fuel-burning heater. In well insulated and weather tight homes, it may inhibit the rate the exhaust ﬂows through the venting system (caused by a shortage of air in the home). The lack of air is caused by many common household appliances which exhaust air from the home (such as a furnace, heat pump, air conditioner, clothes dryer, exhaust fans, ﬁreplaces, and other fuel burning appliances). Also, the combustion process of this heater uses oxygen from inside the dwelling. If the available fresh air delivery in the dwelling is insufﬁcient to support the demands of these appliances, problems can result (i.e. excessive negative pressure will result in performance problems. To correct this problem it may help to open a window (preferably on the windward side of the house) or install an outside combustion air duct to the appliance.

FLOOR PROTECTION

This appliance requires noncombustible ﬂoor protection (the hearth pad or alternate ﬂoor protection material does not require a thermal rating).

A noncombustible ﬂoor protector must fully cover the area beneath the appliance as illustrated in Figure 1.

If the ﬂoor protection is to be stone, tile, brick, etc., it must be mortared or grouted to form a continuous noncombustible surface. In Canada, if a chimney connector / venting extends horizontally over the ﬂoor, protection must also cover the ﬂoor under the connector / venting and at least 2” (51 mm) to either side (recommended but not required in the US).

In addition to the standard installation instructions, the following instructions may be required by local, state or federal building codes:

• Installation should be in accordance with the Manufactured Home and Safety Standard (HUD), CFR 3280, Part 24.

• The stove must be permanently bolted to the ﬂoor lag screws. The lag screws must be an adequate length to extend through the hearth pad and into the ﬂoor as shown in Figures 8 and 9.

Install the lag screws as shown in these ﬁgures. Two lag screws must be used.

•

Connecting the Bella™ stove to outside combustion air is optional, except in manufactured home installations and when required by local building codes. An outside air inlet must be provided for combustion and be unrestricted while unit is in use. Use a galvanized or stainless steel pipe for the duct (the outside air inlet on the stove is 3” diameter). The air intake on the exterior of the home should always be located substantially below the ﬂue termination. The Inlet shall remain free of obstruction while unit is in operation and constructed in a manner so as to prevent material from dropping into the inlet or into the area beneath the dwelling. The inlet shall also have a screen with openings not larger than 1/4" to prevent rodents from entering. See Figure

21.

• Stove must be permanently electrically grounded to the steel chassis of the home using a 8 GA copper wire and a serrated or star washer (to penetrate paint or protective coating to ensure grounding). The location selected for ground attachment to the stove must be dedicated for this purpose. Grounding must comply with NFPA-70-latest edition standards, CSA C22.1-latest edition in Canada, as well as any local codes.

Installation Check List

Draft Adjuster - Adjustment Procedure

It is strongly recommended that you have an Lennox Hearth Products dealer install your stove. If you install your stove yourself, you should review your installation plan with an Lennox Hearth Products dealer.

Check list:

Check off each item as you proceed with the installation process.

q Read the ENTIRE stove installation section ﬁrst q Determine the appropriate measurements and locations for your

installation.

q Follow the installation directions in this manual. q Be sure to pre-ﬁt all items before you install, fasten, or set up the

appliance permanently.

qMeasure for exhaust (also outside air tube when applicable) and mark

the location. Place the unit in place to make sure it's correct before cutting holes in your wall.

Prior to lighting your appliance:

q Review the safety precautions section. q Review the pellet FUEL section. q Review and follow the Operating Instructions. q Plug power cord connector into corresponding connector on the back

of appliance (see Figure 12 showing connector location).

The Bella™ pellet stove has a draft adjuster located at the left side of the stove directly in front of the combustion blower. Should the stove installation require long runs of vent pipe, a situation may be created where excessive combustion air is ﬂowing through the ﬁrebox and causing the fuel to burn faster than it can be delivered to the burn pot. Should this happen, the draft can be slowed down by the adjuster. The stove is shipped with the adjuster half open. To increase or decrease the draft; using a 5/16" open end wrench, loosen the bolt (see Figure 13) and move the adjuster handle toward the center of the stove to decrease and away from the center of the stove to increase the draft. Retighten the screw when adjustment is complete.

Draft Adjuster

The draft adjuster controls the amount of combustion air that is delivered to the ﬁrebox (see Figure 13).

It will be necessary to monitor the appearance of the ﬂame during the ﬁrst 4-8 bags of pellets. If the ﬂame is smoky red or orange with evidence of soot at the top of the ﬂame, the draft adjuster will need to be adjusted to deliver more combustion air. If the ﬂame is "short" at the higher burn rates and appears to burn the pellets out of the pot faster than they can be resupplied, or there are signiﬁcant variations of ﬂame height within a single burn setting, the draft adjuster may need to be adjusted to deliver less combustion air.

After the draft adjuster is adjusted, re-evaluate the appearance of the ﬂame. It may be necessary to continue adjusting it in increments until proper combustion is achieved (the ﬂame should become a brighter yellow and begin to “dance”).

Back of Stove

Plug power cord into connector on back of stove.

Figure 12

After you have begun operation of your appliance:

q Review the routine cleaning / maintenance information. q Enjoy the warmth from your new Lennox Hearth Products pellet

stove!

Once the draft adjuster has been properly set, and if the routine maintenance is performed as needed, the draft adjuster should not require readjustment unless you are changing from a premium grade pellet to a standard or high ash pellet, in which case the draft adjuster may need to be moved outward from center of the stove to help prevent the accumulation of ash in the burn pot.

Draft Adjuster Adjustment Guidelines

Thermostat installation

Lack of Combustion Air:

By opening the draft adjuster, this will increase combustion air delivery. Symptoms of insufﬁcient combustion air include; unburned fuel, lazy smoky or red / orange ﬂame, excessive ash or soot, excessive buildup on glass.

Contributing factors:

• High Altitude – Lack of oxygen

• Restrictive Venting (elbows, horizontal runs, cold external chimneys, etc.)

• Dirty / Poor Quality Fuel.

• Lack of Maintenance

Note: Excessive amounts of ﬂy-ash built-up in the burn pot, clinkers in the burn pot or leakage of air (if the burn pot is not properly seated) will starve the ﬁre for air. See Routine Maintenance, on Pages 25 through

for information on cleaning requirements.

Excessive Combustion Air: Adjusting the draft adjuster to a more closed position will reduce the combustion air delivery. Symptoms of excessive air include; fuel burns too quickly (results in smoking or smoldering pellets), white to yellow ﬂame, etc. If the draft adjuster is open too far, the burning pellets will lift off the bottom of the burn pot and ﬂy up into the air much like popping corn does. Another ﬂame characteristic of a draft adjuster that is open too far is a ﬂame that has signiﬁcant variation in height on any single burn setting.

The Bella pellet stove can be operated manually or by thermostat. The stove comes from the factory wired to operate manually - see control board operation on Pages 19 through 21. A low voltage thermostat can be installed on the stove. To install the thermostat:

1. Unplug the stove from the electrical outlet. Open the control board access door. Locate the black wiring block at the top right on the back side of the control board (see Figure 14). Loosen the two screws B at the back of the block, and remove the U shaped jumper wire A protruding from the block.

2. Insert a wire from the thermostat into one of the slots from which the jumper wire was removed. Repeat this process for the other thermostat wire.

Retain the jumper wire for future reinstallation. See Page 21 for thermostat operation instructions.

IMPORTANT NOTE: Install the thermostat per the manufacturers instructions, provided with the thermostat. Failure to follow manufacturers instructions could result in a malfunction. Pay special attention to the thermostat location requirements. If the location requirements are not adhered to the appliance, erratic operation or failure may occur.

Do not mount the thermostat where it may be affected by:

• Radiant heat from the stove, ﬁreplaces, sun or other heat sources.

• Drafts or dead spots behind doors or in corners.

• Hot or cold air from ducts.

Contributing factor:

• Venting system providing excessive draft.

• Dry, hot burning fuel

Correct Combustion Air / Proper Burn Characteristics:

When the draft adjuster is correctly set, the burning pellets should move (wiggle) around slightly and the ﬂame should be bright yellow and stay at relatively even height.

Outside Air Installations

Connecting the Bella™ pellet stove to outside combustion air is optional, except in manufactured (mobile) home installations and when required by local building codes. The stove’s air intake will accept 3” ID pipe to accommodate outside air installations. The air intake on the exterior of the home should always be located substantially below the ﬂue termination and must remain free of obstruction. The inlet must also have a screen with openings not larger than 1/4" to prevent rodents from entering.

VENTING REQUIREMENTS

It is recommended that only an Lennox Hearth Products dealer install your pellet stove. The speciﬁed installation requirements must be followed to ensure conformity with both the safety listing of the appliance and local building codes. All clearances, installation instructions and precautions speciﬁed by the vent manufacturer must be followed.

Selecting a Location

Review the appliance clearance requirements before installing the venting system (see Pages 5 and 6). Position the appliance far enough away from walls to allow adequate room for servicing. Choose the appliance location with the least amount of interference with the house framing, plumbing, wiring, etc.

Preferred Vent Conﬁguration

For the best performance, we recommend a vent run design which runs vertically and terminates above the roof line. This design will allow natural draft to improve the ﬂow of ﬂue gases and will aid in combustion and stove performance.

Type of Pipe

This stove is approved for venting with Type L and Type PL pellet vent pipe (sometimes referred to as “L-Vent pellet vent”, listed to UL 641 or ULC S609). We recommend the use of venting products manufactured by Security Chimneys International. Connect the pellet vent pipe or the “tee”

to the ﬂue collar using a minimum of three screws and seal as speciﬁed in “Pipe/Liner Joint Requirements” on this Page. Do not use class B gas

chimney or single wall chimney as a substitute. Size of Pipe

These pellet stoves are approved for use with the following vent sizes: 3” (75 mm) standard, or 4” (100 mm), see Page 15 - for determining correct size vent. When 4” pipe is used: for horizontal vent installations use a 3” (75 mm) to 4” (100 mm) adapter - available from vent manufacturer. For vertical installations use a 3” (75 mm) to 4” (100 mm) “tee” - available from vent manufacturer.

Offsets

In every installation, a single or double clean-out “tee” is recommended for every ninety-degree offset (this tee will help collect ash residue and will allow for routine cleaning without the need to disconnect sections of pipe).

Pipe Clearances/Requirements See pipe manufacturers instructions for installation of venting components

and clearances. Follow pipe manufacturers installation precautions for passing pipe through a combustible wall or ceiling (i.e. use an approved thimble).

Notes

• Offsets and horizontal runs accumulate ﬂy-ash and soot which reduces the exhaust ﬂow and performance of the stove.

• Total Offsets in venting system should not exceed 270° total in direc tion change.

• Maximum Vertical Vent - 30 feet (9.14 M)

• Horizontal Runs - The maximum total horizontal run must not exceed 10 feet (3.1 meters).

• Horizontal run of pipe requires 1/4” (7 mm) rise per foot.

• Pellet vent pipe requires 3” (75 mm) clearance from outside of pipe unless otherwise speciﬁed by vent manufacturer - all diameters: 3” (75 mm) and 4” (100 mm). A support bracket must be installed every 4 feet (1.2 m) of pellet vent pipe on the exterior wall of the house unless otherwise speciﬁed by vent manufacturer.

• It is not recommended to terminate exhaust vent on the prevailing wind side of the house.

• In Canada, where the venting may pass through a wall, or partition of combustible materials, the installation shall conform to CAN/CSA-B365. When installing the wall thimble and other venting components, follow the vent manufacturers instructions. Maintain an effective vapor barrier at the location where the chimney or other component penetrates

to the exterior of the structure.

Pipe/Liner Joint Requirements

Silicone sealant and three screws are required to secure the ﬁrst vent connection to the appliance ﬂue collar. Seal the remaining vent sections per the vent manufacturers instructions and secure all sections with 3 screws minimum per section. ALL horizontal joints must be sealed gas-tight (air tight, sealed connection). Use RTV high temperature silicone or Interam, if necessary, to provide a complete seal between vent sections.

Connection to Masonry Chimney through a Wall

Be sure to verify the construction of a masonry chimney, as it may have combustible framing.

Approved liner when relining Masonry or Factory-Built Fireplaces is 2100HT (degree F.) liner listed to UL 1777 or ULC S635.

Connection to an Existing Class A Chimney

A chimney adapter can be used to make the connection from 3” (75 mm) or 4” (100 mm) pellet vent pipe (listed to UL 641 or ULC S609) to existing UL chimney system. Verify with the pipe manufacturer that your pipe brands will interconnect.

Horizontal Vent Installations

On all horizontal vent installations (short, horizontal runs with no vertical pipe); care should be taken when choosing a location for terminating the vent. It is not recommended to directly vent the exhaust on the prevailing wind side of the house. It is recommended that when an appliance is vented directly through a wall, a minimum of 6 feet (1.83 M) of vertical pipe should be installed to create some natural draft. This will reduce the possibility of smoke or odor entering the dwelling during appliance shutdown or loss of power.

Vent Termination

Do not terminate vent in an enclosed or semi-enclosed area such as: carports, garage, attic, crawl space, under a deck, porch, narrow walkway, closely fenced area, or any location that can build up a concentration of fumes such as a stairwell, covered breezeway etc.

Vent surfaces can get hot enough to cause burns if touched. Adults should supervise children when they are in the area of a hot stove. Non-combustible shielding or guards may be required.

Termination Cap

The termination of the outside chimney of the pellet stove shall be located in accordance with the following:

A. Higher than 3 feet (.92 m) above any forced air inlet (air conditioner,

etc.) located within 10 feet (3 m).

B. Not less than 4 feet (1.2 m) below, 4 feet (1.2 m) horizontally from or

1 foot (3.1 m) above any gravity air inlet (door, window, etc.) which ﬂue gases could reenter the dwelling.

C. Not less than 2 feet (.6 m) from combustible materials such as an

adjacent buildings, fences, protruding parts of the structure, roof overhang, plants and shrubs, etc. and not less than 7 feet (2.1 m)

above grade when located adjacent to the public sidewalks (access). The ﬁnal termination of the exhaust system must be conﬁgured so that ﬂue gases do not jeopardize the safety of people passing by, overheat combustible portions of nearby structures or enter the dwelling.

D. Not less than 3 feet (.92 m) below an eave (maximum overhang of 3

feet (.92 m) or any construction that projects more than 2” (51 mm) from the plane of the wall.

E. The distance from the bottom of termination to grade is 12” (305 mm)

minimum. This is conditional upon plants and nature of grade surface: Be careful to choose a location for the vent termination which does not expose people or shrubs to high heat from the exhaust gases. The exhaust gases are not hot enough to ignite grass, plants and shrubs located in the vicinity of the termination although they should be a minimum of 3 feet (.92 m) away. The grade surface under the termination must not be a lawn.

F. Since sparks may escape from the exhaust pipe of any stove, use

caution when positioning the vent pipe. Refer to pipe manufacturer’s instructions when installing and terminating the exhaust. The vent pipe should be horizontal and never run the pipe in a downward direction (recommend a 1/4” [7 mm] rise per foot horizontal).

A ﬂexible corrugated chimney liner has much greater resistance to the ﬂow of ﬂue gases than does a rigid liner. For this reason we recommend that a larger, 4” liner be used on vertical runs exceeding 15 feet or that rigid venting be used. See Figure 18.

If a ﬂexible corrugated chimney liner is used, it must be fully extended to eliminate any sagging and to improve the exhaust ﬂow.

Standard Horizontal Vent Installation

Installing the Bella™ Pellet Stove

This stove is approved for venting with Type L and Type PL pellet vent pipe listed to UL 641 or ULC S609. We recommend the use of venting products manufactured by Security Chimneys International.

1. Locate the proper position for the listed type “PL” wall thimble. Avoid cutting wall studs when installing your pipe. Use a saber saw or keyhole saw to cut the proper diameter hole through the wall to accommodate the wall thimble. Use extreme caution to avoid cutting into power lines within the wall of the home. The hole size will depend on the brand of pellet vent that you are using. Install the wall thimble in the hole.

ALL INTERLOCKING PIPE CONNECTIONS MUST BE SEALED GAS-

TIGHT AND SECURED TOGETHER PER VENT MANUFACTURER INSTRUCTIONS.

Position the stove approximately 12” (305 mm) from the wall on the

ﬂoor pad. Push the “PL” pipe through the wall thimble. Squeeze a bead of high temperature silicone (RTV) sealer around the end of the machined portion of the 3” (76 mm) pipe connector on the back of the stove. Firmly push on a section of “PL” pipe until inner pipe liner pushes into the bead of RTV sealer.

3. Push the stove with pipe attached towards the wall (the pipe will go through the wall thimble). Do not position the back of the stove closer than 2” (51mm) from the wall (see Clearances, Pages 5 and 6).

4. Install listed type “PL” 45 degree elbow with rodent screen or cap on outside end of pipe. The Inlet shall remain free of obstruction while

unit is in operation and constructed in a manner so as to prevent material from dropping into the inlet or into the area beneath the dwelling. The inlet shall also have a screen with openings not larger

than 1/4" to prevent rodents from entering.

5. If the installation includes a source of outside combustion air; cut a separate hole through the wall for the fresh air tube. This tube should be 3” (762 mm) minimum diameter I.D., steel only. Connect outside air pipe to air inlet on stove. This tube must be terminated with a 45 degree elbow or hood.

Notes:

• Combustion air may also be drawn from a vented crawl space under the home.

• All joints for connector pipe are required to be fastened together per the vent manufacturers instructions. If vented horizontally, joints must be made gas-tight (air tight, sealed connection) in a manner as speciﬁed on this page (see instruction #2). INSTALL VENT AT CLEARANCES

SPECIFIED BY THE VENT MANUFACTURER.

• Greater back clearance will improve the ease of serviceability of the stove.

• The end of the exhaust pipe must extend a minimum of 12” (305 mm) from the outside of the building.

IGNITION / HEAT CONTROL

The control board has a six position integrated switch which controls the fuel feed rate, combustion blower speed and room air blower speed simultaneously. There is a separate blower speed control that overrides the integrated switch which will allows you to reduce the speed of the room air blower, thus reducing the noise level of the stove.

The control board regulates all functions of the stove. The following is a list of the board’s components:

•

LCD Display Screen - See LCD Screen Displays on Pages 21, 22 and

23.

The LCD display provides information on the status of the stove, burn mode, failure mode, burn setting, time left in start-up cycle etc. which should result in reduced diagnosis time.

•

Room Air Blower Speed - Adjusts blower speed from low to high settings. When adjusting to lower speed settings, the feed rate may adjust accordingly to the blower speed, so the stove will not overheat.

•

Ignition / Heat Control- Initiates ignition and controls the level of heat output from the stove.

•

Igniter Fuse - Six amp fuse to protect the igniter heating element.

•

Control Board Fuse - Three amp fuse to protect the control board.

NOTE: Upon the stove’s initial light up, or if the stove has previously run out of pellets, the auger feed tube may not contain a sufﬁcient number of pellets to allow the stove to continue burning after the ignition sequence. It may be necessary to initiate the startup a second time by turning the Ignition/Heat Control dial to the "off" position and then back to your desired heat setting. It is important to always empty (when cool) the burn pot of pellets before starting the stove a second time.

WARNINGS

Never empty pellets from the burn pot into the hopper. Pellets that may appear to be cool may retain enough heat to ignite other pellets resulting in smoke or ﬁre damage.

DO NOT OVERFIRE THIS STOVE. This may cause serious damage to your stove and void your warranty. It also may create a ﬁre hazard in your home. IF ANY EXTERNAL PART OF THE UNIT BEGINS TO GLOW, YOU ARE OVERFIRING. Immediately turn the heat control dial to the "OFF" position.

Filling the Hopper

Figure 30 - Control Board

FRONT

BACK

To ﬁll the hopper when stove is off:

1. Lift the hopper lid to it's full opened position.

2. Fill the hopper with pellets.

3. Check to make sure there are no remaining pellets on top of the hopper that may prevent the hopper lid from fully closing.

4. Close Hopper lid.

To ﬁll the hopper when stove is in operation:

1. Repeat steps 1 thru 4 above.

2. When ﬁnished, check the LCD screen on the controller to verify that the stove is still in normal heating mode.

3. If the message on the screen does not say "Heating" rather it alter nates between "Hopper Left Open" and "Cooling Down" simply reset the stove by turning the Heat Control Dial to "Off" and then back to your desired heat setting and the stove will run the igniter for 4-5 minutes to make sure there is a sustainable ﬁre after refueling.

Manual Operation

After the stove is burning (see lighting instructions on Page 19), the heat control dial controls the pellet burn rate and the stove’s heat output. Turning the dial to the low setting allows the stove to burn about 1.8 pounds of pellets per hour. Turning the dial to high allows the stove to burn 4.9 pounds of pellets per hour. Once set, the stove will continue to burn at this rate until shut off.

Thermostat Operation

This stove will operate with a low voltage thermostat. See Page 11 for instructions on installing the optional wall thermostat. Once installed, the thermostat will control the operation of the stove.

IMPORTANT: When connected to a thermostat, it is necessary to turn the heat control dial to your desired heat setting for the initial burn. After the initial ignition sequence, when the thermostat calls for heat (the room temperature is less than the temperature set on the thermostat) and the heat control dial is not in the off position, the stove will burn at the heat control dial setting. The higher the setting, the quicker the room will heat up. Once the thermostat no longer calls for heat (the room is up to the desired temperature), the stove will continue to burn for one additional hour at the lowest setting. If the thermostat does not call for heat again during that hour, the stove will shut off. During that hour, if the thermostat calls for heat again, the stove will again burn at the heat control dial setting until the thermostat no longer calls for heat. If the stove shuts off after that hour it will relight when the thermostat calls for heat.

The hopper lid switch circuit is open which indicates the hopper lid is not properly closed during the ignition sequence. If the hopper lid remains open, the shutdown cycle will start within the time indicated on the display screen. See Page 32 for more information about the hopper switch.

Shut Down - Normal - To turn the stove off, turn the heat control dial to

off. The blowers will continue to operate until the control board completes the shut down cycle.

Power Outage - If the stove has a momentary electrical power loss of less than ten seconds the stove will continue to operate normally when power resumes. If electrical power is interrupted for more than ten seconds the stove will automatically re-enter the start-up mode provided the heat control dial is still in the "On" position. If the stove is connected to a thermostat, the stove will enter the start-up mode when the thermostat calls for heat.

Paint Curing - Stove components have been painted with a high temperature paint. It leaves the factory dry to the touch, but completes the curing process as the stove is used. The paint will cure during the ﬁrst few times the stove is burned. Also some parts of the appliance may be lightly coated with machining oil. Ventilate the house during these ﬁrst ﬁrings as the paint and oil give off carbon dioxide and unpleasant odors. It is recommended that persons sensitive to an imbalance in the indoor air quality avoid the stove during the curing process.

Convection Blower Operation - Your Bella™ pellet stove comes equipped with a temperature activated convection blower that extracts heat from the stove. After the stove warms up, a heat activated switch will turn the blower on. The speed of the blower varies with the burn rate of the stove, but the speed is adjustable with the convection blower speed control knob, as well. The blower will continue to extract heat after the stove shuts off and until it is cooled down.

Due to high temperatures, the stove should be located out of trafﬁc areas and away from furniture and draperies. Children and adults should be alerted to the hazards of high surface temperature and should stay away to avoid burns or clothing ignition. Young children should be carefully supervised when they are in the same room as the Bella pellet stove. Clothing or any other ﬂammable material should not be placed on or near the stove. Any grill, panel, or glass removed for service MUST be replaced prior to operating the stove.

Do not operate appliance with the glass front removed, cracked, or broken. Replacement of the glass should be done by a qualiﬁed service technician.

Lennox Hearth Products, its employees, or any of its representatives assume no responsibility for any damages caused by an inoperable, inadequate, or unsafe condition as a result of any improper operation, service, or installation procedures, whether direct or indirect.

The appliance, when installed, must be electrically grounded in accordance with local codes or, in the absence of local codes, with the National Electrical Code, ANSI/NFPA 70 - latest edition or the Canadian Electrical Code, CSA C22.1 - latest edition.

FUEL

Operating Sounds - As the Bella pellet stove is burning, a number of

normal operational sounds may be heard. Pellets can be heard sliding down the auger tube and into the burn pot. Also, the motor powering the auger can be heard as the control board calls for pellets. Occasionally a loud noise can be heard as the auger cuts a pellet in half. When the blowers come on, the sound of rushing air may be heard. The lower the burn rate the slower the blower operates. Hourly, the combustion blower will blow at a high speed to clean ash from the burn pot.

CAUTIONS

INSTALLATION AND REPAIR SHOULD ONLY BE PERFORMED BY A QUALIFIED SERVICE TECHNICIAN. DO NOT ATTEMPT TO SERVICE THE APPLIANCE YOURSELF.

Avoid overﬁring the stove - do not hand feed pellets to the appliance.

Never use gasoline, gasoline-type lantern fuel, kerosene, charcoal lighter ﬂuid, or similar liquids to start or fresh up a ﬁre in this heater. Keep all such liquids well away from the heater while it is in use.

For your safety, do not install or operate your Bella pellet stove without ﬁrst reading and understanding this manual. Any installation or operation of the appliance deviating from that which is stated in this instruction manual WILL void the warranty and may be hazardous.

CAUTION

The use of unapproved, dirty, wet and / or high salt content fuel will void the warranty!

This stove is designed to burn wood pellet fuel. In addition, a corn/wood pellet mixture, with a maximum of 50 percent corn can be burned. Burning any other fuel that is not approved for use with this appliance will void the appliance warranty. IMPORTANT: The corn/wood mix needs to be

mixed evenly before being put in the pellet stove hopper.

Wood Pellet Speciﬁcations

This appliance has been designed to burn wood residue pellets with up to 3% ash content. Dirty fuel will adversely affect the performance of the stove. Any questions regarding pellet fuel can be answered at the Pellet Fuels Institute (PFI), www.pelletheat.org.4r

Pellet fuel is made from sawdust and scrap wood from many different species of wood. Pellets are either 1/4” or 5/16” in diameter and vary in length. The Bella stove will burn either diameter pellets. Pellets made from hardwoods contain more ash than those made from softwoods. Minerals from ash and sand in the pellets form clinkers under the extreme temperatures in the burn pot. Try burning various brands of pellets until you ﬁnd one that burns with minimum ash and clinkers. Once you ﬁnd a pellet brand that burns well, continue using this brand. High ash fuel increases the frequency of stove cleaning. Fuel with an excessive moisture content may jam the auger assembly.

Clinkering - Silica (or sand) in the fuel, along with other impurities, can

cause clinkering. A clinker is a hard mass of silica formed in the burning process. Clinkering is a function of the fuel, (not the stove), but adversely affects the performance of the stove by blocking off the air passages in the burn pot. Even P.F.I. approved pellet fuel may tend to clinker. See Routine Maintenance (on Pages 25 through 31) for more information on cleaning.

Page 25

Ash - The frequency of removal of the ash and maintenance performed on the stove is directly proportional to the ash content of the fuel and the operation duration of your pellet stove. Low ash fuel may allow longer intervals between cleaning, however, a stove burning high ash fuel may need to be cleaned as often as everyday.

Fuel Feed Rates - Different brands of wood pellets will feed at varying rates due to their size and density (length and diameter). This may require a slight adjustment in the draft adjuster (see Pages 10 and 11).

WARNING

Do not burn treated seed corn! Seed corn is treated with chemical pesticides that are harmful or fatal if swallowed. Burning treated corn will void your warranty!

PLEASE NOTE

turing of wood pellet fuel and will not be held responsible for poor stove performance or any damage caused by poor quality wood pellet fuels.

Pellet Fuel Storage -

• Store your wood pellets in a dry place to prevent them from absorb ing excess moisture.

• Do Not store your wood pellets within the clearance zone of the stove.

• Do Not store your wood pellets in a place that would block access to refueling the hopper.

Wood pellets manufactured to the pellet fuels institute (P.F.I.) certiﬁcation standard are available in two grades, Standard and Premium. The primary difference between the two is the ash content of the pellets.

The P.F.I. speciﬁcation for standard grade & premium grade residential pellet fuel is as follows:

• CHLORIDES (Salt): Less than 300 p.p.m. to avoid stove and vent rusting.

• BULK DENSITY: 40 lb. / Cu. Ft. minimum

• MOISTURE CONTENT: 8% maximum

• ASH CONTE (premium grade)

• FINES: 0.5% maximum through a 1/8” screen

• BTU CONTENT: There are a number of variations in pellet fuels that are not included in PFI standards. For example, BTU (heat value) content may range from just under 8,000 to almost 9,000 BTU, depending upon species and region of the country and other variables.

Corn Fuel Speciﬁcations

Use only clean-shelled corn with a moisture content less than 15% and approximate fuel value of 7000 BTU/lb (16,200 kJ/kg). Do not attempt to burn corn with higher moisture content or burn lesser grade fuels. Do not burn other types of agricultural pellets or by-products (alfalfa, cherry pits, olive pits, nut shells, etc.) as they are not permitted to be burned in these appliances.

Shelled corn can be burned in the Bella pellet stove when it is mixed with wood pellet fuel. The mixture can contain a maximum of 50 percent corn. Burning corn may create more ash than wood pellets and may necessitate the need to clean the burn pot and glass more frequently.

Store corn in a tight container and use methods to ensure the corn does not become rain soaked or absorb moisture from damp or wet sources. This will also prevent rodents from becoming a problem. Do not store corn within stove installation clearances.

NOTES:

• Corn with excessive grain dust must be screened, by sifting with 3/16" mesh screening. Large pieces of cob may plug the auger.

NT: < 2% maximum (standard grade) < 1% maximum

ROUTINE MAINTENANCE

IMPORTANT CAUTIONS:

• UNPLUG POWER CORD AND ENSURE APPLIANCE IS COLD BEFORE PERFORMING ANY MAINTENANCE WORK.

• Some brands of pellets produce more ash and clinkers than others. Therefore the frequency of performing the following cleaning procedures depends to a great degree on the quality of the pellets burned.

• Not cleaning this unit will cause it to burn poorly and will void your warranty for this appliance.

• When removing ash build-up, use an approved ash vacuum only. A cleaning brush can be used to loosen any ash build-up before vacuuming. DO NOT USE A STANDARD HOUSEHOLD VACUUM OR “SHOP VAC” AS THE FILTERS WILL LEAK THE FINE PARTICLES OF ASH INTO THE HOME.

Required Cleaning Schedule After Number Of Bags Burned:

Burn Pot = 10 bags Ash Pots = 20 bags Flue Passageways = 50 bags Combustion Blower = 100 bags Convection Blower = 100 bags

Notes

• Cleaning schedule will vary depending on quality of pellets used. Burning high ash pellets will require more frequent cleaning.

• Using a drop cloth is recommended as some ash may spill onto the ﬂoor during the cleaning process.

Opening the Glass Door

CAUTION: Do not open the front door when the stove is hot. To open the

glass door, ﬁrst you must open the front cast iron door. Facing the front of the stove gently pull the far left edge of the door towards you, the front cast iron door will open about 90 degrees to uncover the door sealing the ﬁrebox (see Figure 31). Once the front cast iron door is open, locate the door latch handle (B in Figure 31) and pull towards you which will release the seal to the ﬁrebox and allow you to gain access to the burn pot and ash pots. To close door, repeat these steps in reverse order.

• When changing from burning all wood pellets to burning a corn and wood pellet mix, the draft adjuster may need to be adjusted to achieve proper combustion.

Burn Pot Cleaning - The combustion blower comes on at high speed

once an hour to blow the by-products of combustion out of the burn pot. However, the burn pot should be cleaned more thoroughly after burning about 10 bags of pellets. The burn pot has a number of holes in the bottom and sides that provide combustion air to the pellets. The extreme temperatures in the burn pot can cause the impurities in the pellets to form ash and clinkers. When the stove is cool, open the front door and lift out the cast iron burn pot. Scrape the inner bottom and sides of the pot with a screwdriver to remove all ash and clinkers from these surfaces. Make sure all the holes in the pot are open. Place the burn pot in the hole from which it was removed. Make sure the high side of the pot is rotated toward the front of the stove (see Figure 34). Push the burn pot down so surface A is tight against the steel supporting the pot. Do not substitute any other grate or pot for use in this stove.

High Side Of Burn Pot Goes Toward Front Of Stove

Ash Pots Removal and Cleaning

CAUTION: Do not remove the ash pots when the stove is hot. To

remove the ash pots, rotate open front casting and then front door (as explained on Page 25). Gloves are recommended when reaching inside the ﬁrebox to lift ash pots up and out of ﬁrebox. When ash pots are free of ash and cleaned, replace in the appropriate sides making sure the pots are fully seated to the bottom of the ﬁrebox. Once in place, close and latch the glass door and close the front cast iron door (see Figure 35).

CAUTION: Disposal of Ashes - Ashes should be placed in a metal container with a tight ﬁtting lid. The closed container should be placed on a non-combustible ﬂoor or the ground - well away from all combustible materials, pending ﬁnal disposal. If the ashes are disposed of by burial in soil or otherwise locally dispersed, they should be retained in the closed container until all cinders have been thoroughly cooled.

Reinstall the ash pots by placing them in the left and right bottom of ﬁrebox making sure they are seated on the bottom of the ﬁrebox. Note that if the ash pots do not seal tightly to the stove, the control board may detect a leak and shut the stove down.

Cleaning the Combustion Blower and Proof of Fire Switch

To clean the combustion blower, begin by unplugging the stove, opening the left side door and locating the combustion box clean-out cover in the lower left corner of the stove (C in Figure 37). Using a 5/32" allen wrench remove the four screws securing the cover. Once the cover is off, gently brush off the blades as well as the Proof of Fire switch (the small circular object just behind the blades near the bottom. Figure 39) and vacuum out all loose ash. When clean, inspect the silicone foam gasket on the cover for damage, replace if necessary and reinstall the cover being sure to tighten the bolts down evenly.

Note: Failure to clean the proof of ﬁre switch when needed may result in nuisance shut-downs because the ﬂy-ash build-up insulates heat from reaching the switch.

(Recommended Frequency of 1 year or after every 100 bags of fuel used)

Cleaning the Vent Pipe

Soot and Fly-Ash: Formation and Need for Removal

The products of combustion will contain small particles of ﬂy-ash. The ﬂy-ash will collect in the exhaust venting system and restrict the ﬂow of the ﬂue gases. Incomplete combustion, such as occurs during start-up, shutdown, or incorrect operation of the room heater will lead to some soot formation which will collect in the exhaust venting system. The exhaust venting system should be inspected at least once every year to determine if cleaning is necessary. Inspect frequently and clean when necessary. Fly-Ash will accumulate at all bends in the exhaust system. Sweep the pipe as needed. A tee and clean-out in the vent system attached to the stove’s ﬂue collar will facilitate this cleaning.

Large amounts of ﬂy-ash build-up will create a lack of combustion air. Removing the clean-out tee cap on vertical installations will allow an inspection of the ash build-up in the clean-out tee and will help you to decide how frequently more extensive cleaning must be performed.

.......... Cat. No. 70K99 Touch Up Paint, Metallic Black

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 sandpaper 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.

Motor Lubrication

The blowers are permanently lubricated by the manufacturer. Do not apply oil to any part of the blower, doing so may cause damage.

COMPONENT DEFINITIONS

• Air Wash

The air wash is a portion of the incoming combustion air that is split

off and routed to ﬂow across the inside of the glass door which helps the viewing area stay clean.

• Auger (A)

A motor powered screw device that transfers the fuel from the hopper

to the feed chute to deliver pellets to the burn pot.

• Auger Motor (B)

Drives the auger. Motor speciﬁcations are: .4 Amp, 1.28 RPM (revolu

tions per minute). The auger motor turns the auger, lifting pellets up the auger tube. The pellets are then dropped down a tube and into the burn pot. The auger is controlled by the control board.

• Blower, Convection (Room Air) (C)

The blower function is to transfer the heat from the appliance to heat

the room air.

• Blower, Combustion (Exhaust) (D)

It has a radial impeller to deliver more air to the burn pot. It pulls

air into the burn pot by creating a negative pressure. This is done by extracting the exhaust gases out of the ﬁrebox and pushing the exhaust downstream to the ﬂue exit.

• Convection Blower Snap Switch (F140-20F, N/O*) (E) This switch is located on the snap switch bracket (along with the high

limit and pre-high limit snap switches) just inside the right side door on the back of the ﬁrebox. When the stove reaches 140° F this switch automatically closes and activates the convection blower. When the stove drops below 120° F the switch opens again turning the convection blower back off.

• High Limit Snap Switch (Manual Reset) (L225F N/C*) (F) This switch is located on the back right of the stove in the snap switch

bracket with the convection blower snap switch and pre high limit snap switch. It is designed to shut down the stove if it senses an overﬁre condition (it opens at 225° F). This snap switch has a reset button on it and will not allow the stove to start-up until the reset button has been pushed.

• Low Limit Proof of Fire Snap Switch (Ceramic, F140-10F, N/O*) (G) - This switch is located on the combustion blower. This switch

will close at 140° F and will not open until it reaches a temperature of 130° F. It is designed to shut down the stove if it does not detect the heat of a ﬁre at the end of the initial startup period or if your stove has emptied the hopper.

• Pre High Limit Snap Switch (F200-40F, N/C*) (H)

This snap switch is N/C and opens at 200° F. It will close when the

temperature cools to 160° F. It is located on the back right of the stove in the snap switch bracket with the high limit snap switch and blower snap switch. This switch will slow the feed rate of your auger motor if your convection blower is running at a less then optimal setting and heating up the stove beyond normal heating levels.

• Hopper Lid Switch (I)

This switch is located on the upper right rear of the hopper. It detects

whether the hopper lid is open and will turn off the auger motor if the

hopper lid is not properly closed. When opening the hopper, when refueling, do not allow the hopper lid to remain open too long or the ﬁre may extinguish. NEVER DISCONNECT OR BYPASS THIS SWITCH

FOR ANY REASON.

• Hopper (J)

The hopper is where the pellets are stored.

• Igniter (K) The automatic igniter is designed to light the fuel when the stove is in

the lighting mode. The igniter superheats air that is pulled through the burn pot by the combustion blower to light the fuel. The igniter remains energized for the ﬁrst seven minutes of the lighting sequence.

• Vacuum Switch (L)

The vacuum switch located on the right rear of the stove behind the

ﬁrebox on the vacuum switch bracket. If a low pressure is created in the ﬁrebox by a leak, opening the front door, a blocked ﬂue, or unsealed ash pots, the vacuum switch will sense it and cause the stove to go into a shutdown mode.

Some other possible causes for this switch to trip are as follows:

• High altitude or other misc. environmental conditions affecting exhaust ﬂow.

• Improper venting system.

• Burn-Pot (M) This is where combustion occurs.

Electrical Generator Operation

Your Bella™ pellet stove can be powered with a gas driven electrical generator. However, the generator’s electrical regulator may not be compatible with the stove’s electronics. The higher the quality of the generator, the greater the chance that it is compatible with the stove.
