Thank you for purchasing the BOSCA SPIRIT 500 Pellet stove. You are now prepared to burn wood in
the most efficient, convenient way possible. To achieve the safest, most efficient and most enjoyable performance from your stove,
you must do three things:
1) Install it properly;
2) Operate it correctly; and
3) Maintain it regularly.
The purpose of this manual is to help you do all three.
This stove has been independently tested to ASTM E 1509-04 Standard Specification for Room Heaters, Pellet Fuel Burning Type 1,
UL 1482-1998 Standard for Solid Fuel Room Heaters, Oregon Administrative Rules for Mobile Homes (814-23-900 through 814-
23-909) and Installation as a Stove Heater.
This pellet stove, 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.
This appliance is designed specifically for use only with pelletized wood. It is designed for residential
installation according to current national and local building codes as a freestanding residential installation
according to current national and local building codes as a freestanding room heater. It is also approved as a mobile home heater
which is designed for connection to an outside combustion air source.
The stove will not operate using natural draft or without a power source for the blower systems and fuel feed system and must
not be burned with any type of coal (see "PROPER FUEL").
This stove is designed to provide the optimum proportions of fuel and air to the fire in order to burn free of smoke and soot. Any
blockage of the air supply to or from the stove will seriously degrade its performance and will be evidenced by a smoking exhaust
and a sooting window.
For best operation the ash content of the pellet fuel should be less than 1% and the calorific value
approximately 8200 BTU/LB. Avoid high ash content fuels because this will rapidly fill up the burn pot and eventually cut off the
combustion air supply.
Commercial and industrial installations of BOSCA SPIRIT 500Pellet stove should not be used since operational
control is often not well managed in these settings.

Installation Through Side of Masonry Chimney
(Refer to fig. Nº 10)
NOTE: Follow L-Vent chimney manufacturer’s instructions.
•Position the stove, adhering to the clearances in Figures 1 & 2. Mark the center of the hole where the
pipe is to pierce the masonry chimney. It will be necessary to break out the masonry around the location
of the pipe center mark. Use a 4-inch diameter hole for 3-inch pipe and 5-inch diameter hole for a
4-inch pipe.
•Measure and build chimney top plate. Cut out holes for chimney pipe, and if used cut necessar
holes for the outside air pipe. Install the tee on the bottom of the vertical pipe system and lower it
down the chimney until the center branch of the tee is level with the center of the hole in the
masonry, as shown in fig. Nº10.

pipe, and while holding the pipe at the proper elevation, affix the collar with a minimum of three
1/4” stainless steel sheet metal screws. Seal all joints and seams around the collar.
•Connect the horizontal pipe by pushing it through the hole in the masonry and lining it up with
the branch in the tee. Push the pipe into the tee while twisting it to lock it into the tee.
•If desired, once the horizontal pipe is in place, the space between the pipe and masonry may be filled with
high-temperature grout.
•Install the trim collar. An adjustable pipe length and adapter may be needed to finish the connection
to the stove.

For installation in a mobile home, an outside source of combustion air must be used (see “COMBUSTION AIR SUPPLY”).The outside
source of combustion air must be unrestricted while the appliance is in use to prevent room air starvation, which causes smoke spillage.
Some spillage could also set off smoke alarms.
•The stove must be grounded to the steel chassis of the home with 8 Ga. Copper wire using a serrated or star washer
to penetrate paint or protective coating to ensure grounding.
•The stove must be securely fastened to the floor of the mobile home using 2, 1/4” lag bolts that are long enough to
go through both a hearth pad, if used, and the floor of the home.
•Use RTV High Temp silicone to create an effective vapor barrier at the location where the chimney or other component
penetrates to the exterior of the structure.
• Refer to “VENTING” for proper exhaust configurations.
fig. Nº10
ELECTRICAL INSTALLATION
This stove is provided with a 6-foot grounded electrical cord extending from the rear of the stove. We recommend connecting
to a good quality surge protector that is plugged into a standard three-prong, 120V, 60hz electrical outlet. Voltage variations
can lead to serious performance problems. The BOSCA SPIRIT 500 Pellet stove electrical system is designed for 120V AC with
no more than 5% variation. Bosca cannot accept responsibility for poor performance or damage due to inadequate voltage. If
connected to an older, two-prong outlet, a separate ground wire should be run to a proper ground (refer this to a qualified
technician). Always route the electrical cord so that is will not come in contact with any hot part of the stove.

SPECIAL MOBILE HOME REQUIREMENTS
WARNING: DO NOT INSTALL IN A SLEEPING ROOM.
CAUTION
THE STRUCTURAL INTEGRITY OF THE MOBILE HOME FLOOR, WALL
AND CEILING/ROOF MUST BE MAINTAINED.

On/Off Switch
When pushed, the stove will automatically ignite. No other firestarter is necessary. The
igniter will stay on for at least 10 and up to 15 minutes, depending on when Proof of
Fire is reached. The fire should start in about 5 minutes.
The green light located above the On/Off button (in the On/Off box) will flash during
the ignition start-up period (see fig. Nº11).
The Feed Rate Advance is inoperable during the ignition start period. When the red light
continuously stays on, the Feed Rate Advance can be adjusted to achieve the desired heat
output.
NOTE: If the stove has been shut off, and you want to re-start it while it is still warm, the
“On/Off” button must be held down for 2 seconds.
fig. Nº11
High Fan Switch
The room air fan speed varies directly with the feed rate. The “HIGH FAN” switch
overrides this variable speed function. It will set the room air blower speed to high at
any feed rate setting.
When the “HIGH FAN” button is pushed the room air fan will switch to its highest
setting.
When this button is pushed again, the room air fan will return to its original setting
based on the Feed Rate Advance setting.
Reset Trim
Different size and quality pellet fuel may require adjustment of the “1” feed setting on
the Feed Rate Advance bar graph. This is usually a one-time adjustment based on
the fuel you are using. The “RESET TRIM” button when adjusted will allow for 3
different feed rate settings for the #1 feed setting only. To adjust simply push the
“RESET TRIM” button while the stove is operating at setting “1” and watch the bar
graph.

Amber
Light On
Fuel Feed Switch
When the “Fuel Feed” button is pushed and held down the stove will feed pellets
continuously into the burnpot. While the stove’s auger system is feeding pellets the
amber light (in the “Fuel Feed” box”) will be on. (See fig. Nº12)
fig. Nº12

When the “1” and “3” lights are illuminated on the bar graph the low feed rate is at its “lowest setting". (approx. 0.9 pounds per hour).
When the “1” light is illuminated on the bar graph the low feed rate is at its “normal” setting.
When the “1” & “4” lights are illuminated on the bar graph the low feed rate is at its “highest” setting.
NOTE: When the stove is set on “1” the “reset trim” values will be shown on the Feed Rate Advance bar graph. For example if the
Reset Trim is set to low the “1” and “3” lights will be illuminated on the bar graph.
Heat Level Advance
This button when pushed will set the pellet feed rate, hence the heat output of your stove. The levels of heat output will incrementally
change on the bar graph starting from level “1” to “4”.
NOTE: When dropping more than 2 heat level settings (i.e. 4 to 1) push the “High Fan” button and allow the room air fan to run
at that setting for at least 5 minutes to prevent the stove from tripping the high temp thermodisc. If the high temp thermodisc does
trip see “SAFETY FEATURES”.
Factory-approved pellets are those 1/4” or 5/16” in diameter and not over 1” long. Longer or thicker pellets sometimes bridge the
auger flights, which prevents proper pellet feed. Burning wood in forms other than pellets is not permitted. It will violate the building
codes for which the stove has been approved and will void all warranties. The design incorporates automatic feed of the pellet fuel
into the fire at a carefully prescribed rate. Any additional fuel introduced by hand will not increase heat output but may seriously
impair the stoves performance by generating considerable smoke. Do not burn wet pellets. The stove’s performance depends heavily
on the quality of your pellet fuel.
Avoid pellet brands that display these characteristics:
Excess Fines:“Fines” is a term describing crushed pellets or loose material that looks like sawdust or sand. Pellets can be screened
before being placed in a hopper to remove most fines.
PROPER FUEL
Binders: Some pellets are produced with materials to hold them together, or “bind” them.
High Ash Content: Poor quality pellets will often create smoke and dirty glass. They will create a need for more frequent
maintenance. You will have to empty the burnpot plus vacuum the entire system more often. Poor quality pellets could damage
the auger. Bosca cannot accept responsibility for damage due to poor quality pellets. Your dealer can recommend a good quality
pellet dealer in your area.
OWNER´S MANUAL
-15-
THIS STOVE IS APPROVED FOR BURNING PELLETIZED WOOD FUEL ONLY
NOTE: Bosca pellet stoves are equipped with a hopper safety switch, if hopper lid is open the auger will not drop pellet fuel. If the
hopper lid is left open for a prolonged period of time the unit will shut down.
Remove burnpot, making sure it is clean and none of the air holes are plugged. Clean the firebox, and then reinstall burnpot. Clean
door glass if necessary (a dry cloth or paper towel is usually sufficient). Never use abrasive cleaners on the glass or door. Check fuel
in the hopper, and refill if necessary. Make sure hopper lid id closed, If left open auger will not feed pellets.
PRE- START- UP CHECK
Never use a grate or other means of supporting the fuel. Use only the Bosca approved burnpot.
NOTE: During the first few fires, your stove will emit an odor as the high temperature paint cures or becomes seasoned to the metal.
Maintaining smaller fires will minimize this. Avoid placing items on stovetop during this period because paint could be affected.
BUILDING A FIRE
Proper Fuel Storage: Keep fuel raised off the floor and in a covered area to avoid moisture and water contact.
CAUTION: DO NOT PLACE FUEL WITHIN SPACE HEATER INSTALLATION OR
WITHIN THE SPACE REQUIRED FOR CHARGING AND ASH REMOVAL.

The fire goes out and the auger motor and blowers will run until the stove cools. This will take 30 to 45 minutes. After the stove
components stop running, the “Power” and the BAR GRAPH lights stay on for 10 minutes. After the 10 minutes the “3” light on the
bar graph will flash and the “Power” light will go off. To restart, refill hopper, press “Power” button, and then press “Fuel Feed” button
until pellets begin to fall into burnpot.
PULL (close)
PUSH (open)
A.- Fill hopper with pellet fuel.
B.- Make sure burn pot is seated in correct position and or clean.
C.- Press power button "On/Off" make sure light comes on and close hopper lid.
D.- Adjust damper to 1/2” to 3/4” open (pushed in is open). This will vary depending on your installation and elevation. Once fire is
established, adjust for desired flame increasing the amount the damper is open as the heat setting is increased. (see “DAMPER
CONTROL”)
E.- Adjust the pellet fuel feed rate to desired setting by pressing Feed Rate Advance "Heat Level" button.
If stove doesn’t start in 15 minutes, press Power "On/Off, wait a few minutes and go thru start procedure again with step C.
OPENING DOOR
If the door is opened while the stove is in operation it must be closed within 30 seconds or the stove will shut down.
If the stove shuts down, push the “Power” button to continue the operation of your stove.
ROOM AIR FAN
When starting your stove the Room Air Fan will not come on until the stove’s heat exchanger warms up. This usually takes about 10
minutes from start-up.

NOTE: You will have to prime the auger system before stove will ignite, you may have to go thru 2 to 3 start up cycles each cycle
last 15 minutes stove will shut you then must go thru start procedure again.
NOTE: To speed up the time it takes to prime auger system you may press and hold the hopper switch, and press and hold the auger
button on control board once you have turned stove on by pressing the power button. This allows the auger to turn continually when
you hear pellets drop into burn pot close hopper lid and unit will continue in start up mode.
IF STOVE RUN OUT OF PELLETS
DAMPER CONTROL
The Damper Control rod, on the stove’s lower right front
side, adjusts the combustion air. This control is necessary
due to the varied burn characteristics of individual installations, different
pellet brands and pellet feed rates. It allows you to improve the efficiency
of your stove. Providing correct combustion air will reduce the frequency
of cleaning your glass door and prevent the rapid buildup of creosote
inside your stove and chimney. You should adjust the damper based on
the fire’s appearance. A low, reddish, dirty fire can be improved
by pushing the damper in slightly. A “blow torch” fire can be improved by
pulling the damper out a bit.
As a general rule, on lower feed rate settings, the damper
should be out farther. On higher feed rates, the damper should be more
open. Through trial and error, you will find the best setting. Consult your
dealer if you need help.
NOTE: On “1”, damper should be out approximately 1/2”
to 3/4”. If damper is out too far, it can cause the fire to go
out. Remember push in damper for more air, pull out for
less air.

REFUELING
We recommend that you not let the hopper drop below 1/4 full.
KEEP HOPPER LID CLOSED AT ALL TIMES EXCEPT WHEN REFILLING.
IF LEFT OPEN AUGER WILL NOT FEED.
DO NOT OVERFILL HOPPER.
THERMOSTAT INSTALLATION
SHUTDOWN PROCEDURES
Turning your BOSCA SPIRIT 500 Pellet stove off is a matter of pressing the “Power” control panel switch. The red light will go out.
The blowers will continue to operate until internal firebox temperatures have fallen to a preset level.
SAFETY FEATURES
A.- Your stove is equipped with a high temperature thermodisc. This safety switch has two functions:
1. To recognize an overheat situation in the stove and shut down the fuel feed or auger system.
2. In case of a malfunctioning convection blower, the high-temperature thermodisc will automatically shut down the auger,
preventing the stove from overheating.
NOTE: The thermodisc has no reset button and will reset itself once the stove has cooled. The manufacturer recommends
that you call your dealer if this occurs as this may indicate a more serious problem. A service call may be required.
B.- If the combustion blower fails, an air pressure switch will automatically shut down the auger.
NOTE: Opening the stove door for more than 30 seconds during operation will cause enough pressure change to activate the air
switch, shutting the fuel feed off. Close the door and press “On/Off” button to continue operation of your stove.
Your BOSCA SPIRIT 500 Pellet stove is ready to plug-in a thermostat (a millivolt thermostat is required).
To connect your stove to a thermostat, follow these instructions:
•Unplug the stove from power outlet
• Find the white/red wire to connect the thermostat, located at the back of the stove, near the Control Board.
• Plug the wires of the thermostat.
• Plug the stove to the power outlet..
OWNER´S MANUAL
-17-
To switch between any of the three modes the stove must be shut off, the new mode selected, and the stove restarted.
Modes
Manual Mode
(see fig. Nº14 a)
In this mode, the stove will operate only from the Control Panel, as detailed in the “OPERATION” section of this Owner’s Manual.
On/Off Thermostat Mode
(see fig. Nº14 b)
In this mode when the home is warm enough the stove will shut off. The fans will continue to run until the stove cools.
When the home cools below the thermostat setting, the stove will automatically restart and run at the last feed rate setting.

fig. Nº14 a fig. Nº14 b fig. Nº14 c
Set damper control rod approximately 1/2” to 3/4” out. This will vary depending on elevation and weather conditions. Observe stove's
operation and adjust damper
OWNER´S MANUAL

High/Low Thermostat Mode
(see fig. Nº14 c)
When engaged in this mode, the stove will automatically switch between two settings. When warm enough, it will switch to the
#1 or low setting. The room air blower will also slow to its lowest speed.
NOTE: You must press “On/Off” button to start and stop stove when in this mode.
The Heat Level Advance setting on the bar graph will stay where it was initially set. When the house cools below the thermostat,
the stove will switch to the feed rate of the heat level advance setting.

OPERATING SAFETY PRECAUTIONS
KEEP ALL LOOSE OR MOVEABLE HOUSEHOLD COMBUSTIBLES, SUCH AS FURNITURE, DRAPES, TOYS, ETC. AT LEAST
THREE FEET FROM THE OPERATING STOVE.
WARNING: DO NOT OPEN THE DOOR DURING THE START UP CYCLE AND DO NOT ADD PELLETS TO THE
BURNPOT BY HAND AT ANY TIME, OTHERWISE A DANGEROUS CONDITION COULD RESULT.
Pellets should be stored in a dry place. The pellets should not be stored within 12” of the stove.
DO NOT STORE OR USE FLAMMABLE LIQUIDS, EXPECIALLY GASOLINE, IN THE VICINITY OF YOUR SPIRIT 500 PELLET.
NEVER USE A GAS OR PROPANE TORCH, GASOLINE, GASOLINE-TYPE LANTERN FUEL, KEROSENE, CHARCOAL
LIGHTER FLUID OR SILIMAR FLUIDS TO START OR “FRESHEN UP” A FIRE IN THIS HEATER.
WARNING: 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. IFANY EXTERNALPART OF THEUNIT BEGINSTO GLOW, YOU AREOVERFIRING. Immediately
press the “POWER” switch on the Control Panel.
PLEASE READ THIS !
Hot while in operation. Keep children, clothing, and furniture away. Contact may cause skin burns.
If you notice a smoldering fire (burnpot full but no visible flame) AND a heavy smoke buildup in firebox immediately TURN
OFF the stove, but DO NOT unplug it. Do not open the door, change the damper setting or tamper with any controls
on the stove. Wait until firebox clears, and blowers shut down, do as instructed in "PRE -START UP CHECK" and “BUILDING
A FIRE”, then attempt to restart the fire. If the problem persists contact your Dealer.
Do not open stove door when operating unless necessary. This will create a dirty, inefficient burn and could allow smoke spillage or
sparks to escape.
Do not permit operation by young children or those unfamiliar with stove’s operation.
Do not service or clean this appliance without disconnecting the power cord.
Do not abuse the door glass by striking, slamming or similar trauma. Do not operate the stove with the glass removed, cracked or
broken.
If the stove is installed in a room without air conditioning, or in an area where direct sunlight can shine on the unit, it is possible this
can cause the temperature of the stove to rise to operational levels; one of the sensors could then make the convection fan and /or
feed system start on its own. It is recommended that the stove be unplugged when not in use for extended amounts of time (i.e. during
summer months).
Maintain proper ventilation. It is important that adequate oxygen be supplied to the fire for the combustion
process. Modern houses are often so well insulated that it may become necessary to open a window
slightly or install an outside air vent to provide sufficient combustion air. Since heating with a solid fuel is
potentially hazardous, even with a well made and thoroughly tested stove, it would be wise to install
strategically placed smoke detectors and have a fire extinguisher in a convenient location, near an exit.
