INTRODUCTION
Thank you for purchasing the HYBRID-35 pellet stove & insert. 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.
PLEASE read this entire manual before installation and use of this pellet fuel-burning room
heater. Failure to follow these instructions could result in property damage, bodily injury or
even death.
Keep this manual handy for future reference.
Your HYBRID-35 has been independently tested to ASTM E1509-04 Standard Specification for room
heaters, pellet fuel burning type 1 and the HYBRID-35 insert has been independently tested to ASTM
E1509-04 Standard Specification for room heaters, pellet fuel burning type 1, UL 1482-1998 Standard
for solid fuel room heaters and ULC-S628-93 Standard for fireplace inserts.
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 and CSA-C22.1.
This appliance is designed for use with pelletized wood only. Do not burn coal of any type in this
appliance. It is designed for residential installation according to current national and local building
codes as a freestanding or insert 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 blowers and fuel feed
system.
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 8,200
BTU/LB. Avoid burning high ash content fuels because this will rapidly fill up the burn pot and
eventually cut off the combustion air supply.
The HYBRID-35 should not be used for commercial or industrial applications since operational control
is often not well managed in these settings

COMBUSTION AIR SUPPLY
For a mobile home installation the stove must be connected to an outside
source of combustion air. A 3” inside diameter metallic pipe, either flexible
or rigid, may be attached to the inlet at the stove’s rear (refer to figures 4, 5
& 6). A rodent guard (minimum 1/4” wire mesh) must be used at the
terminus (refer to figure 5). All connections must be secured and airtight by
either using the appropriately sized hose clamp and/or UL-181-AP foil tape.
For mobile home installations only: combustion air supply conduit may
not exceed 10 feet.
Sources of Outside Combustion Air
•A hole in the wall behind the stove.(Figure 5)
•A hole in floor near stove rear terminating only in a ventilated
crawl space.(Figure 6)
WHEN OUTSIDE AIR IS NOT USED
If outside air is not used, it is important that combustion air be easily
available to the air inlet. A closable outside air register can be used in
tightly insulated homes.
VENTING
The HYBRID-35 is certified for use with a vent certified to UL-103 or ULC
S629M and a chimney type vent certified to UL-641 or ULC-S-609-M89
and ULC/ORD C441-M90, with 3” or 4” inner diameter. In Canada, we
recommend that you usea listed pellet vent that meets the ULC S-609-M89
and ULC/ORD C441-M90 Standards. For the United States, we
recommend that you use a listed pellet vent that meets the UL-641, 7th
edition Standard.This unit can be vented in an existing chimney with the
addition of a liner if the chimney is more than 4” in diameter. Class “A”
chimney is not required. Refer to the instructions provided by the vent or
chimney manufacturer, especially when passing through a wall, ceiling, or
roof.
Your venting system should have at least one foot of vertical rise for
each foot of horizontal run. The total vertical rise should never be
less than 3 feet (see Appendix A).
This is a pressurized exhaust system. All vent connector joints must be
sealed and fastened in accordance with the pellet pipe manufacturer's
instructions to ensure consistent performance and avoid smoke and ash
spillage.
DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING
ANOTHER APPLIANCE.
DO NOT INSTALL A FLUE DAMPER IN THE VENTING SYSTEM OF
THIS UNIT.

FILTERS INSTALLATION AND CLEANING
The two filters for your convection blowers are supplied with the owner’s manual. Although the filters are not mandatory, they are useful to prevent dust
from being dispersed into the room where the stove is located. If you install the filters, please make sure that they are cleaned on a regular basis as per
our recommended maintenance schedule. This is particularly critical if you have animals in your house, such as a dog or a cat. Filters that are not
cleaned can clog up and cause your stove to overheat. You may also damage or burn the convection blowers. In order to install the filters, simply insert
them in the slot just above the blower’s finger guard. To clean the filters, use a vacuum or remove the filters and rinse them with hot water.

10
EQUIVALENT VENT LENGHT (EVL)
The longer the run of pipe in your installation, the more restriction there is
in the system. Therefore, larger diameter pipe should be used for longer
runs.
•Use 4” pipe if you have more than 15 feet of Equivalent Vent Length
(EVL).
•Horizontal runs shall not exceed 10 feet of EVL.
•To calculate EVL, use the following conversions table:
Qty Type of pipe EVL equivalent(ft)
1 90° elbow or “T” 5
1 45° elbow 3
1 ft Horizontal pipe run 1
1 ft Vertical pipe run 0.5
NOTE: At altitudes above 3,000 feet, we suggest the use of 4” diameter
vent at an EVL of 7 feet or more.
Here is an example on how to calculate the EVL of your installation. (See
Figure 16)
(3 x 4’ of vertical length = 12’ x 0.5 = 6 EVL) + (1 x elbow or "T" = 5 EVL) +
(2 x 1’ of horizontal length = 2 EVL)
Total EVL = (6 + 5 +2) = 13. So 3” diameter vent is allowed
Note: Do not count the outside termination (goose neck) in the EVL
calculation.
INSTALLATION CONFIGURATIONS
A. HORIZONTALLY THROUGH WALL (REFER TO FIGURE 7, 8, OR 10)
NOTE: Follow Vent chimney manufacturer’s instructions.
1. Position stove, adhering to clearances shown in Figures 1 & 2.
2. Determine position of hole in wall; directly behind stove exhaust vent
(refer to figure 4).
3. Always maintain 3” clearance from combustible materials.
4. Install Vent wall thimble per Vent manufacturer’s instructions.
5. Attach enough piping to penetrate and extend at least 6 inches
beyond the exterior wall. There should always be at least one foot of
vertical rise for each foot of horizontal run (see Appendix A). At least
3 feet of vertical rise are needed in all cases. A longer vertical rise will
favour a better exhaust.
6. To reduce the risk of smoke spillage, never terminate with a horizontal
run. If your system terminates with a horizontal run, add at least 3 feet
of vertical rise (see Appendix A).
7. Attach cap and seal outside wall thimbles with non-hardening
waterproof mastic.
Termination should not be located so that hot exhaust gases can ignite
trees, shrubs, or grasses or be a hazard to children. Exhaust gases can
reach temperatures of 500ºF and cause serious burns if touched.

OPERATION
PROPER FUEL
THIS STOVE IS APPROVED FOR BURNING PELLETIZED WOOD FUEL ONLY! Factory-approved pellets are those 1/4” or 5/16” in diameter and
approximately 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. This stove
feeds pellets automatically at a preset rate, adding fuel 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:
a. 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 hopper to remove most fines.
b. Binders – Some pellets are produced with materials to hold them together, or “bind” them.
c. 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 burn pot and vacuum the entire system more often. Poor quality pellets could damage the auger. OSBURN cannot accept
responsibility for damage due to poor quality pellets. The pellet ash content should be less than 1%. The pellet grade and ash content should be
indicated on the bag by the pellet manufacturer.
PRE-START-UP CHECK
Remove burn pot, making sure it is clean and none of the air holes are plugged. Clean the firebox, and then reinstall burn pot. 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.
BUILDING A FIRE
Never use a grate or other means of supporting the fuel. Use only the OSBURN approved burn pot.
NOTE: During the first few fires, your stove will emit an odor and a small amount of fumes 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. Make sure the
room is well-ventilated. Open windows. Odors and fumes released during this process are unpleasant but they are not toxic.
LIGHTING PROCEDURE
a. Fill hopper and clean burn pot.
b. Press on-off button To select the thermostat mode, press . It will blink every 5 seconds to indicate the mode as been
selected. After 2 minutes, when the display turns itself off, the thermostat icon will be displayed at 50% of is brightness.
c. If the flame is too low in the burn or the stove have difficulty to light. Adjust the air supply toward the minimum setting for start-up. In some
situations, it may be necessary to have the damper completely closed for ignition to take place. After there is a flame, the damper can then be
adjusted for the desired feed setting. If that doesn’t fix, verify if the burn pot gaskets are in place and in good condition.
d. Adjust feed rate to desired setting by pressing the desired level on the gradient 1 to 6.
If the fire doesn’t start within 30 minutes, refer to troubleshooting section.
DISPLAY BOARD

UNIT CONTROLS
The blowers and automatic fuel supply are controlled from the panel on the HYBRID-35. The control panel functions are as follows:
Note:
1- To display the available functions, just touch the control board at any place
2- Select the desired function
*The display will turn itself off after 2 minutes.
MODE BUTTON
•When the on-off button is pressed, the stove will automatically ignite. The heat level must be selected manually to adjust the stove’s heat output to
the desired level. If the thermostat mode is selected, the stove will automatically modulate between the lowest heat level and the heat level
selected to keep the room temperature at the thermostat’s setting. If the set room temperature is achieved while the stove has been running at the
lowest heat level for more than 45 minutes, the unit will automatically shut off and will start another ignition cycle only when the thermostat calls for
heat again(stove has to cool down completely before igniting again). No fire starter is necessary to ignite the unit. The auger will feed fuel for 4
minutes and the electronic igniter will stay on for 10 minutes. If the unit doesn’t ignite within 15 minutes, the stove will wait for 5 minutes and will
start a second ignition cycle. If ignition fails a second time, a warning message will appear on control panel.
•The Heat Level may be selected during the ignition cycle and can be modified in heating mode. However, the unit will only feed fuel at the desired
heat level setting when the heat sensor located into the stove receives a signal indicating that the unit has ignited. This may take anywhere
between 10 and 15 minutes.
FUEL FEED SWITCH
•By activating this function, the stove will feed for 1 minute and the display will blink. You can stop the distribution by touching the sign a second
time or by starting the stove.
CAUTION: THIS FUNCTION CAN ONLY BE OPERATED WHEN THE STOVE IS IN “OFF” POSITION. THE FUEL FEED SWITCH IS USED TO
PRIME THE AUGER WHEN THE AUGER IS EMPTY.
NOISE REDUCER
•The convection blowers speed varies according to the fuel feed rate. A dimmed display indicates that the blowers is in low noise mode.
•When the “NOISE REDUCER” button is pushed, the convection blowers will switch to their lowest speed. The convection blowers will remain at
their lowest speed unless the stove reaches a certain temperature. If this occurs, the convection blowers will go back to its highest setting to cool
down the stove. The low noise button will have to be pressed again for the convection blowers to go back to their lowest speed.
HEAT LEVEL
•By pressing the gradient, you can set the pellet feed rate and hence the heat output of your stove. The levels of heat output will change and each
gradient will indicate the level from 1 to 6.
RESET
The reset icon is used to clear any warning on the control before restarting your stove. This icon is only visible when you have a warning code on
the display.
OPENING DOOR
The door should be opened only for maintenance purposes.
CONVECTION BLOWERS (ROOM AIR FANS)
Upon starting your stove, the convection blowers will not come on until the stove’s heat exchanger has warmed up. This usually takes about 10 to 15
minutes from start-up. Speed will vary with the selected feed rate, except if the noise reducer mode has been activated.

17
COMBEXtm
Your stove uses a unique patented technology called COMBEX. As opposed to most other pellet stoves, which use only an
exhaust blower, your HYBRID-35 uses a motor on which are mounted two housings with impeller blades. One housing serves
for combustion, and the other for exhaust. This is why we refer to the combustion/exhaust blower throughout this manual.
The COMBEX system balances combustion air and uptake to provide clean, worry-free combustion which is less dependent
on the leak-tightness of the device and the quality of the combustible.
IF THE STOVE RUNS OUT OF PELLETS
The fire goes out and the auger motor and blowers will run until the stove cools down. This will take a few minutes.
After the stove’s components stop running, a warning message will appear .
To restart, press , refill the hopper , and press until pellets begin to fall into the burn pot. Press to start the unit.
COMBURANT AIR DAMPER CONTROL
The damper control on the stove is located the right hand side panel or on the right hand side decorative panel for the insert. This control is used to
adjust the air intake manually depending on the type of installation and different brands of pellets used. It allows you to improve the efficiency of your
stove. Providing correct combustion air will reduce the frequency of cleaning your door glass and reduce creosote build-up 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 increasing the air supply using the damper
rod. A “blow torch” fire can be improved by reducing the air supply.
Through trial and error, you will find the best setting. Consult your dealer if you need help.
REFUELING
We recommend that you do not let the hopper drop below 1/4 full. If the hopper lid stays open more than 3 minutes, a warning will appear. To
restart, press icon, and then press .
For insert installation, use the removable door handle to open and close the hopper lid(Figure 38 & 39)
Figure 38
Removable handle
Figure 39
Hopper lid
KEEP HOPPER LID CLOSED AT ALL TIMES EXCEPT WHEN REFILLING. THE HOPPER MAY BE FILLED WHILE THE STOVE IS OPERATING.
DO NOT OVERFILL HOPPER. DO NOT TOUCH THE UNIT WITH THE PELLET BAG. HOT SURFACE MAY MELT THE BAG.

18
SHUTDOWN PROCEDURE
Turning your OSBURN stove off is a matter of pressing on the control panel. The blowers will continue to operate until internal firebox
temperatures have fallen to a preset level. The stove cannot restart before it has completely shut down.
SAFETY FEATURES
a. Your stove is equipped with a manual reset high temperature switch (also called heat sensor or heat switch). The switch has a reset button on
its backside. Like a circuit breaker, once tripped, the reset button will have to be pushed before you can restart the stove. The high
temperature switch protects the stove against overheating due to of an evacuation problem, a control board problem, a blower problem, or any
other problem causing the unit to overheat. The manufacturer recommends that you contact your dealer if this occurs as it may hide a major
problem. A service call may be required.
NOTE: If an overheating situation occurs, the high temperature switch (called the L-250 manual reset) will automatically shut down the auger
motor (fuel feed system) and a warning code will appear.
b. If the combustion blower fails, an air pressure switch will automatically shut down the auger and a warning message will appear. This
safety feature is to prevent the unit from igniting or burning fuel when the combustion/exhaust blower has failed, therefore preventing
combustion fumes from spilling into the room.
c. If the temperature in the auger rises beyond a certain acceptable level, two high temperature switches located under and above auger housing
will stop the fuel feed system and a warning will appear.
CODE BEFORE RESETING TO RESET
H1, H2, H3
OR H4 Heat exchanger and/or exhaust system is/are clogged. Refer to the owner’s manual
for maintenance procedures. Press simultaneously for 2 seconds and
icons.
*** After 3 attempts, reset is no longer possible, call SBI technical support.

OPERATING THE STOVE USING A THERMOSTAT
A thermostat will help you maintain a constant house temperature
automatically. A millivolt or 24 Volt thermostat is required. A fixed wall
mount or remote model can be used.
THERMOSTAT INSTALLATION
•Unplug the stove from the power outlet.
•Connect two thermostat wires to the terminal block located on the
lower right side of the back of the stove. To do so, loosen the two
screws and insert the wires in the terminals. Tighten the two screws.
(See Figure 41)
•If you are using a wireless wall thermostat or a hand held thermostatic
remote control, you can locate the receiver behind the stove’s back
panel, on the right side, just below the terminal block. Most receivers
are already equipped with quick-connect terminals. Simply unplug the
PC board wires connected to the back of the terminal block and
connect them directly with the receiver’s terminals. Location of the
thermostat is very important to obtain the best comfort and efficiency
from you HYBRID-35. The thermostat should be mounted 50 inch
from the floor on a wall located 15 to 20 feet from the stove. You
should avoid installing directly in front of the stove to avoid
cycling.(See Figure 42)

MODES
THERMOSTATIC MODE
•To engage this mode, the thermostat icon must be pushed
upon starting the stove. The heat setting is then selected using the
“Heat Level” selector. When set in thermostatic mode, the stove will
automatically run at the heat level selected until the set room
temperature is reached. When that occurs, the stove will switch to
heat setting #1 (lowest) until the thermostat calls for heat again. The
convection blowers will also slow down to low speed. When the
thermostat calls for heat again, the stove will automatically switch
back to the selected heat level.
•N.B.: If the room temperature remains stable and the thermostat
does not call for heat during at least 45 minutes, the stove will shut
down. When the thermostat calls for heat again, the stove will start an
ignition cycle. Once the ignition cycle is completed, the stove will
increase its feed rate to match the heat level selected.
•N.B.: It is possible to change the setting of your unit such that if the
thermostat does not call for heat after 45 minutes, the unit will remain
at the lowest heat setting (#1) but will not shut down (this is the PILOT
ON mode). The stove will remain at the lowest heat level until the
thermostat calls for heat again. If you prefer that your unit runs
following that logic, you need to change the setting to PILOT ON by
the pressing the following two buttons on the PC Board:
First press , hold it, and then press . Hold the two
buttons for a couple of seconds.
•Once you do that, the letters P, I, L, O, T, O, N will appear on the PC
Board to let you know that you are in the “PILOT ON” mode. If you
wish to go back to the default thermostatic mode (i.e. the unit shuts
down after 45 minutes if the thermostat does not call for heat), simply
press the same two buttons again for a couple of seconds. The letters
P, I, L, O, T, A, U, T, O will appear on the PC Board to let you know
that you are in the “PILOT AUTO” mode.
NOTE: When in thermostatic mode:
•You should not operate the manual control or play with the
temperature setting.
•YOUR THERMOSTAT SHOULD BE INSTALLED BY AN
AUTHORIZED DEALER OR QUALIFIED TECHNICIAN.
