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 1509-95 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 palletized 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 550 Pellet Stove should not be used since operational
control is often not well managed in these settings.

•Do not operate your stove if you smell smoke coming from it. Turn it off, monitor it,
and call your dealer.
•Never use gasoline, gasoline-type lantern fuel, kerosene, charcoal lighter fluid, or similar liquids
to start or “freshen up” a fire in this stove. Keep all such liquids well away from the stove while
in use.
• Never block free airflow through the open vents of the stove.
•Never try to repair or replace any part of the stove unless instructions are given in this Manual.
All other work should be done by a trained technician.
•The stove will not operate during a power outage. If an outage does occur, check the stove
for smoke spillage and open a window if any smoke spills into the room.
•Disconnect the power cord before performing any maintenance or repairs on the stove.
NOTE: Turning the stove “Off” does not disconnect all power from the stove.
•Do not unplug the stove in you suspect a malfunction. Turn the stove off, periodically inspect
it, and call your dealer.
• Keep foreign objects out of the hopper.
•Do not throw this Manual away. This Manual has important operating and maintenance
instructions that you will need at a later time. Always follow the instructions in this Manual.
• Do not place clothing or other flammable items on or near the stove.
• The viewing door must be closed and latched during operation.
• Do not operate the stove if the flame becomes dark and sooty or if the burnpot overfills with
pellets. Turn the stove off, periodically inspect it, and call your dealer.
•Hot while in operation. Keep children, clothing, and furniture away. Contact may cause skin
burns. Educate all children of the danger of a high temperature stove. Young children should
be supervised when they are in the same room as the stove.
•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 stove start on its own. It is
recommended that the stove be unplugged when not in use for extended amounts of time
(i.e. during the summer months).

ANOTHER APPLIANCE.
DO NOT INSTALL A FLUE DAMPER IN THE EXHAUST
VENTING SYSTEM OF THIS UNIT.
INSTALL VENT AT CLEARANCES SPECIFIED BY THE VENT
MANUFACTURER.
EQUIVALENT VENT LENGTH (EVL)
The longer the run of pipe in your installation, the more restrictions there is in the system. Therefore,
larger diameter pipe should be used.
Use 4” pipe if you have more than 15 feet of equivalent vent length. Horizontal runs shall not
exceed 10 feet of EVL. It is recommended that vertical runs be a minimum of 8 feet.
To calculate EVL, use the following conversions:
90º elbow or “T” = 5 equivalent feet
45º elbow = 3 equivalent feet
Horizontal Pipe Run = 1 equivalent foot per actual foot
Vertical Pipe Run = 0.5equivalentfootperactualfoot
NOTE: At altitudes above 3,000 feet, we suggest the use of 4” diameter vent at an EVL of 7
feet or more.

WARNING: DO NOT INSTALL IN A SLEEPING ROOM.
For installation in a mobile home, an outside source of combustion air must be used (see
“COMBUSTION AIR SUPPLY”).
•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.
ELECTRICAL INSTALLATIONS
SPECIAL MOBILE HOME
REQUIREMENTS
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.
OWNER´S MANUAL

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.
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)
OWNER´S MANUAL

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”.
CAUTION
THE “4” SETTING IS DESIGNED FOR TEMPORARY USE ONLY. IF USED FOR
EXTENDED PERIODS, IT CAN SHORTEN THE LIFE EXPECTANCY OF THE UNITS
COMPONENTS. AVOID USE AT THIS SETTING FOR MORE THAN ONE HOUR AT A TIME.

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:
PROPER FUEL
OWNER´S MANUAL
-19-
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.
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.
THIS STOVE IS APPROVED FOR BURNING PELLETIZED WOOD FUEL ONLY
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.
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.
