Cautions & Warnings
For use with solid wood fuel only – preferable dry, seasoned cord wood.
- HOT WHILE IN OPERATION. KEEP CHILDREN, CLOTHING AND FURNITURE AWAY. CONTACT MAY CAUSE SKIN BURNS.
- DO NOT INSTALL IN A MOBILE HOME.
- DO NOT BURN GARBAGE OR FLAMMABLE CHEMICALS OR FLUIDS SUCH AS GASOLINE, GASOLINE-TYPE LANTERN FUEL, KEROSENE, CHARCOAL LIGHTER FLUID, NAPHTHA, ENGINE OIL, OR SIMILAR LIQUIDS TO START OR ‘FRESHEN UP’ A FIRE IN THIS STOVE. SOME OF THESE FUELS CAN GENERATE DEADLY CARBON MONOXIDES. KEEP ALL SUCH LIQUIDS WELL AWAY FROM THE STOVE WHILE IT IS IN USED.
- DO NOT CONNECT TO ANY AIR DISTRIBUTION DUCT OR SYSTEM.
- DO NOT ELEVATE THE FIRE BY USE OF A LOG CRADLE OR GRATES. BUILD FIRE DIRECTLY ON A 1 INCH LAYER OF ASH SPREAD EVENLY OVER THE BASE OF THE FIREBOX.
- DO NOT STORE FUEL UNDERNEATH THE APPLIANCE, WITHIN THE SPECIFIED INSTALLATION CLEARANCE AREAS, OR WITHIN THE SPACE REQUIRED FOR CHARGING AND ASH REMOVAL.
- ALWAYS CLOSE THE DOOR AFTER THE IGNITION. LEAVING DOOR OPEN CAN CAUSE SMOKE SPILLAGE AND FLAMES TO COME OUT OF THE STOVE AND CREATE DANGEROUS SITUATIONS.
- NORMAL OPERATION OF THE STOVE WILL RESULT IN MOMENTARY EMISSIONS OF SMOKE INTO THE ROOM WHEN THE REFUELING DOOR IS OPENED AND CLOSED. IT IS ALWAYS RECOMMENDED TO INSTALL STRATEGICALLY PLACED SMOKE DETECTORS AWAY FROM THE STOVE AND TO HAVE A FIRE EXTINGUISHER IN A CONVENIENT LOCATION. MAKE SURE THAT THEY ARE NOT INFLUENCED BY SMALL AND NORMAL WISPS OF SMOKE THAT CAN COME OUT OF THE STOVE AT THE IGNITION OR REFUELING BUT CLOSE ENOUGH TO PROVIDE SAFETY.
- NEVER OVER FIRE YOUR STOVE. IF ANY PART OF THE STOVE STARTS TO GLOW RED, OVER FIRING IS HAPPENING. READJUST THE AIR INTAKE CONTROL AT A LOWER SETTING.
- NEVER PUT WOOD ABOVE THE FIREBRICK LINING OF THE FIREBOX.
Certification Label
Before Installation
After unpacking, check that the following parts are included inside the firebox:
- 2 side baffles
- Handle for top air control
- Lifter for cook plates
- Allan key for adjustment of top air
Assembling the Stove
The N550 comes mostly assembled, however some parts may need adjusting / to be added before firing the stove. It is important that the following components are used ensure compliance.
INSTALLING THE BY-PASS DAMPER
Before installing the flue, the by-pass damper handle must be fitted. The handle is supplied inside the firebox. Insert the threaded end of the handle into the 10mm hole on left side of stove. Looking down through the flue spigot locate the threaded end of the handle with the extended nut attached to the by-pass damper. Screw the handle all the way into the nut until tight.
The position of the handle should be at approximately 11 o’clock when the damper is open, and 1 o’clock when the damper is shut.
DO NOT ALTER THE DAMPER ADJUSTMENT RANGE TO INCREASE FIRING FOR ANY REASON.
INSTALLING FIRE BRICKS
The stove comes with 4 fire bricks 9” x 4 ½” x 1 ½” (230mm x 115mm x 38mm) and a 19” (480mm) long brick retainer as well as two triangular bricks 2” x 2 ¾” x 10” (50 x 70 x 250mm) for the front. Refer to figure 1
Place the four fire bricks upright, up against the rear wall of the firebox.
Place the U-shaped brick retainer over the top of the bricks such that the
bricks fit inside the U-section. This will hold them in place. Place the
triangular firebricks at the front of the firebox beneath the door opening.
(Note: the firebricks may already be in place upon arrival of the new
appliance.)
INSTALLING BAFFLE PLATE
The stove comes with a 10” x 12 ¾” x 6” (250(d) x 325(w) x 150(h) mm) baffle plate. This rests on the two lugs welded to the inside front of the firebox and on the brick retainer at the back of the stove.
Position the baffle plate vertically towards the rear of the firebox with the 4” (100mm) strip welded to the baffle at the top facing forward. Bring the top edge towards the front of the stove so that it slides up and over the two support lugs with the 4” (100mm) strip located between them. Raise the lower rear edge of the baffle plate to rest on top of the brick retainer.
With the baffle plate in its correct position, ensure it is pushed all the way back so that it doesn’t fall.
INSTALLING TOP AIR CONTROL ROD
A stainless-steel rod with a thread at one end and black knob on the other
will have been supplied in the stove. Pass the threaded end of the rod through
the hole near the top front corner on the left side of the stove. Push the rod
through until one can feel it has located the nut on the air slide, then screw
rod until tight. Refer to figure 2. Check that the rod slides freely back and
forth.
INSTALLING THE FLOOR PROTECTOR
The stove must be placed on a non-combustible floor protector with an R-value
of 2.12 or greater.
For multiple layers, add R-values of each layer to determine the overall
R-value. When manufacturers provide a k-factor or C-factor for the material,
you will need to convert these to the R-value.
The following equations can be used to convert these factors to the R-value:
- k-factor, is given with a required thickness (T) in inches: R=1/k x T
- C-factor, is given:
R=1/C EXAMPLE:
If the floor protector is 4” brick with a C-factor of 1.25, over 1/2” mineral
board with a “k” factor of 0.29, the total R-value of the system (Rtotal) is:
4” brick C = 1.25,
1/2” mineral board K = 0.29,| Rbrick = 1/1.25
Rmineral = 1/0.29 x 0.5| = 0.8
= 1.724
---|---|---
Rtotal = Rbrick + Rmineral,| Rtotal = 0.8 + 1.724| = 2.524
In this example, the R-value is greater than 2.12 required and therefore this floor protector is a suitable combination that provides the required thermal protection.
In the USA, the floor protector must extend 8” beyond each side of the flue loading door and 16” to the front. In Canada, the floor protector must extend 8” (200mm) beyond each side and the back of the appliance and 18” (450mm) to the front. Refer to figure 3.
In a rear vent installation, the floor protection must also extend under the stove pipe / chimney connector and a minimum of 2” (50mm) beyond each side.
Positioning the Stove
STANDARD INSTALLATION CLEARANCES
One of the main necessary precautions when installing a wood stove is to leave sufficient space between the stove (top, sides, back, front, and under stove pipes) and any other material that can catch fire.
It is extremely important that you respect required installation distances and that you respect local installation regulations. This is for your safety! The manufacturer is not responsible for the product, if it is not installed following these recommendations. The following clearances may only be reduced by means approved by the regulatory authority.
A combustible surface is anything that can burn (i.e. sheet rock, wall paper,
wood, fabrics etc.)
These surfaces are not limited to those that are visible and include materials
that are behind noncombustible materials. If you are not sure of the
combustible nature of a material, consult your local fire officials.

Description | Dimension (inches) | Dimension (millimeters) |
---|---|---|
A – Back Wall to Flue Pipe | 12.5” | 318mm |
B – Side Wall to Flue Pipe | 22.5” | 572mm |
C – Wall to Flue Pipe | 15” | 381mm |
D – Back Wall to Appliance | 10” | 254mm |
E – Side Wall to Appliance | 12” | 305mm |
F – Wall to Appliance | 5” | 127mm |

Chimney Connection
The chimney connector is a single walled pipe used to connect the stove to the chimney. For use with the N550 Bakers Oven the chimney connector MUST be 6” (150mm) in diameter, with a minimum thickness of 24-gauge black steel or 26-gauge blued steel. The chimney connector must be suitable for solid fuel, in good condition, and kept clean.
Aluminum and galvanized steel pipe is not acceptable for use with the N550 Bakers Oven. These materials cannot withstand the extreme temperatures of a wood fire and can give off toxic fumes when fired.
DO NOT USE THE CONNECTOR PIPE AS A CHIMNEY.
Each chimney connector or stove pipe section must be installed to the stove flue collar and to each other with the male (crimped) end toward the stove, as per figure 5.a. Attach each of the sections to one another with three equidistant metal screws, as per figure 5.b.
This prevents any amount of condensed or liquid creosote from running down the outside of the pipe or the stovetop. All joints, including the flue collar connection must be secured with three sheet metal screws to ensure that the sections do not separate.
For the best performance, the chimney connector should be as short and direct as possible, with no more than two 90° elbows. The maximum horizontal run is 36” (915mm) and a recommended total length of stove pipe should not exceed 10 feet. Always slope horizontal runs upward ¼” per foot toward the chimney.
No part of the chimney connector may pass through an attic or roof space, closet or other concealed space, or through a floor ceiling. All sections of the chimney connectors must be accessible for cleaning. Where passage through a wall or partition of combustible construction is desired, the installation must conform to NFPA 211 or CAN/CSA-B365, and is also addressed in this manual.
Chimney Requirements
DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE. DO NOT CONNECT TO ANY AIR DISTRIBUTION DUCT OR SYSTEM.
This stove must be connected to a 6” (150mm) factory built UL 103 HT chimney (ULC S629, inCanada) or a code- approved masonry chimney with a flue liner.
An effective vapor barrier at the location where the chimney or component penetrates to the exterior of the structure must be maintained as per the installer’s complying method.
Factory Built Chimney
When a metal prefabricated chimney is used, the manufacturer’s installation
instructions must be followed. You must also purchase (from the same
manufacturer) and install the ceiling support package or wall pass-through and
“T” section package, firestops (where needed), insulation shield, roof
flashing, chimney cap, etc. Maintain proper clearance to the structure as
recommended by the manufacturer. The chimney must be the required height above
the roof or other obstructions for safety and proper draft operation. See page
11 for chimney termination requirements.
Masonry Chimney & Fireplace
The stove may also be connected to a masonry chimney, provided the chimney complies with the construction rules found in the building code enforced locally. To ensure that a masonry chimney meets the minimum standards of the National Fire Protection Association (NFPA) it should be inspected by a professional to make sure there are no cracks, loose mortar or other signs of deterioration and blockage. Also have the chimney cleaned before the stove is installed and operated.
When connecting the stove through a combustible wall to a masonry chimney, special methods are needed. Refer to figure 7. The chimney must have either a clay liner or a suitably listed stainless steel liner. If the masonry chimney has a square or rectangular liner that is larger in cross sectional area than a round 6” (150mm) flue, it should be relined with a suitably listed 6” (150mm) stainless steel liner. Do not downsize the flue to less than 6” unless the venting system is straight and exceeds 25ft (7.6mt) in height. When passing through a combustible wall, the use of an insulated listed thimble is required.
There are listed kits available to connect a stove to a masonry fireplace. The kit is an adapter that is installed at the location of the fireplace damper. The existing damper may have to be removed to allow installation.
Chimney Height
A masonry chimney or a listed factory-build chimney must be the required
height above the roof and any other nearby obstructions. The chimney must be
at least 3’ (900mm) higher than the highest point where it passes through the
roof and at least 2’ (600mm) higher than the highest part of the roof or
structure that is within 10’ (300mm) of the chimney, measured horizontally.
Refer to figure 8.
