THE STOVE LOCATION
It is very important to position the wood stove as close as possible to the chimney, and in an
area that will favor the most efficient heat distribution possible throughout the house. The
stove must therefore be installed in the room where the most time is spent, and in the most
spacious room possible.
Recall that wood stoves produce radiating heat, the heat we feel when we are close to a
wood stove. A wood stove must never be installed in a hallway or near a staircase, since it
may block the way in case of fire or fail to respect required clearances
Pre Installation
The following need to be considered before installation to ensure the safe operation of your stove:
• Adequate air supply to ensure efficient combustion.
• A well- sealed chimney system.
• The protection of combustible materials in proximity of the stove.
Draught Requirements
It is essential for the safe and efficient use of your stove that you provide an adequate air supply to
your stove to ensure a proper draught. This may mean the provision of an outside air supply to the
room, especially if there are extraction units such as cooker hoods or clothes dryers in the vicinity.
Failure to do so will mean that fuel is burned inefficiently causing smoke and blackening the glass and
may also cause smoke to come back into the room. As a simple check for this open a door or window
in the room and check if the stove burns more efficiently. Soot and blackening around the outside of
the stove must not be tolerated.

Installation
IF YOU’RE BORU STOVE IS NOT PROPERLY INSTALLED, OPERATED AND MAINTAINED, A
HOUSE FIRE MAY RESULT. FOR SAFETY, FOLLOW ALL INSTALLATION, OPERATION AND
MAINTENANCE DIRECTIONS. CONTACT LOCAL BUILDING OFFICIALS ABOUT
RESTRICTIONS, PERMITS AND INSTALLATION INSPECTION REQUIREMENTS IN YOUR AREA.
Unpacking and readying your stove for installation.
1. Remove box from around the stove. Check glass and breakages. Do not install a damaged
stove.
2. It is recommended that your stove be installed by an experienced and certified stove installer.
Contact your local dealer for advice.
3. Open the door and check that the multi tool and flue spigot is inside. This is used to open the
door when hot, and also remove the ash pan.
4. Attach 6” flue spigot to either top or rear of the stove. If attaching to rear, remove blanking
plate from top and attach blanking plate to rear. The use of any make-shift or connections
that are not as specified can cause an unsafe condition and will void the warranty.
5. Your stove is pre-assembled and ready for installation.
6. In the unlikely event that your multi tool or spigot are missing please contact your local dealer.
Well -Sealed Chimney Flue System
1. Only materials and items approved for solid fuel stoves should be used for your stove.
2. Under no circumstances should you use aluminum or galvanized steel pipes for your stove
flue.
3. An always fit pipe with the narrow side down, this allows any creosote or soot to run down the
inside of the pipe and not to come out and cause a mess and create hazard of fire.
4. All joints in the flue system (pipes etc.) should be sealed with fire cement and/or an
appropriate fire resistant rope or gasket.
5. Pipe bends should be kept to a minimum and it is not recommended using more than 2 bends
on any installation.
6. Flues must not pass through ceilings, floors, attics, roofs, combustible walls or any
combustible material without adequate and approved insulation being provided to protect
combustible materials.
7. The chimney and flue provide a means of taking combusted fuel from the stove, as well as a
draft to enable the stove to work. It is essential that the flue system is kept in good condition
and there are no breaks or cracks allowing contact with any other combustible materials of
8
Boru Stoves® BCMUS
SAVE THESE INSTRUCTIONS
the house. It is also essential that the flue system is kept clean and seals are maintained to
ensure the draft is not lost. A blocked chimney flue could result in death or serious injury.
8. The open end of the flue system must be above the height of the apex of the building and any
other obstructions, such as trees, which are within 3 meters (10ft) of the flue system. Failure
to do this will affect the efficiency of the stove and may cause down drafts which will mean
dangerous products of combustion are emitted into room.
9. Under no circumstances should the flue pipe be less than 6” (150mm) internal diameter.
Chimney Connection
The chimney connector is a single walled pipe used to connect the stove to the chimney.
For use with the appliance the chimney connector MUST be 6” in diameter, with a minimum thickness
of 24 gauge black steel or 26 gauge blued steel.
The chimney and chimney connector must be suitable for solid fuels and be in good condition and
kept clean.
Aluminum and galvanized steel pipe is not acceptable for use with the appliance. These
materials cannot withstand the extreme temperatures of a wood fire and can give off toxic
fumes when heated.
9
Boru Stoves® BCMUS
SAVE THESE INSTRUCTIONS
Do not use the connector pipe as a chimney.
Each chimney connector or stovepipe section must be installed to the stove flue collar and to each
other with the male (crimped) end toward the stove.
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 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” and a recommended total length of
stovepipe 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 CAN/CSA-B365, Installation Code for solid –Fuel-Burning Appliances and
Equipment.

Masonry Chimney
Ensure that a masonry chimney meets the minimum standards of the National Fire Protection
Association (NFPA) by having it inspected by a professional. Make sure there are no cracks, loose
mortar or other signs of deterioration and blockage. 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.
13
Boru Stoves® BCMUS
SAVE THESE INSTRUCTIONS
Weather conditions
The weather conditions outside the building could have an effect on the burning performance of the
Boru stove.
These could include:

Windy days - smoking from the appliance. This could be caused by turbulent airflow around
chimney terminal, possibly caused by the position of other buildings or obstacles nearby. This
problem is, also, sometimes associated with oversize chimneys, which may even have
downdraught problems on calm days. If smoking is a common problem on windy days make a
note of the wind strength and direction before consulting your appliance installer, who will
advise you on possible solutions to the problem, after visiting the installation.

Damp / Rainy days – These sometimes result in problems when lighting and maintaining the
fire, due to the lower flue temperatures and smaller difference between indoor and outdoor
temperatures reducing the flue draught. Also, rain water running down the inside of the
chimney reducing the flue temperatures. To help with this problem care must be taken to use
good quality kindling wood, when starting the fire, and running the stove at a higher heat
setting than normal for a period after start-up to fully heat the chimney. It could be possible to
fit a rain cowl to the chimney to reduce this problem. Your appliance installer should advise
you on possible solutions. If the Boru Carraig Mór stove emits smoke into the room
continuously, close the air controls and allow the stove to go out, and ventilate the room to
clear the fumes. Do not re-light the appliance until the cause of the problem is identified and
rectified.
Symptoms of poor performance related to flue draught include:

Excessive fuel consumption (high flue draught)

Poor burning control, overheating (high flue draught)

Wind noise from air controls (high flue draught)

Difficulty getting a fire going and keeping it burning well (low flue draught)

Low heat output (low flue draught) Smoke entering room when doors opened (low flue
draught)The construction, position, size and height of the chimney are all factors that affect
the performance of the flue draught.

Other factors that can affect the flue draught include:

Trees or other buildings nearby causing turbulence

High and gusty winds

Outside temperature

FLOOR PROTECTOR
Your wood stove should be placed on a non-combustible surface with an R value of 1.0 and listed
UL1618. For multiple layers, add R-values of each layer to determine the overall R-value. The floor
protector should be under the stove, eighteen inches beyond the front and eight inches beyond each
side of the fuel loading and ash removal opening. If there is a horizontal section of chimney
connector, the chimney protector should go under it and two inches beyond each side Convert
specification to 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 1/8" mineral board with a “k” factor of 0.29
the total R-value of the system is:
4" brick C=1.25, R=1/1.25=0.8
1/8" mineral board K=0.29, R=1/0.29 x 0.125=0.431
Total R = R brick + R mineral = 0.8 + 0.431 = 1.231
Total R is greater than 1.0, the system is acceptable.

Installation Clearances
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. These clearances may only be reduced
by means approved by the regulatory authority.
One necessary precaution 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. 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 also include materials that are behind noncombustible materials. If you are not sure of the combustible nature of a material, consult your local
fire officials.

Operating Your Boru Stove
1. Build fire directly on base of the stove.
2. Only open door to fuel/refuel the stove. Operating the stove with the door open will result in
excess air that will cause the stove to over fire.
DO NOT OVER FIRE, IF CHIMNEY OR STOVE IS GLOWING RED YOU ARE OVER
FIRING CAUSING AN UNSAFE CONDITION. EVIDENCE OF OVER FIRING WILL VOID
YOUR WARRANTY.
3. Do not build the fire too close to the glass. Do not abuse the glass doors. Do-not strike or
slam shut the door. Glass is fragile!
Fuel
Your stove is designed to burn solid wood fuel only; it is not designed to burn the following:
1. Paper or cardboard, other than small amounts used to light stove
2. Treated or painted wood
3. Synthetic fuel or logs that are not approved for solid fuel stoves
4. Household rubbish
5. Liquid fuels
6. Plastics
Burning these or other products for which the stove was not designed may damage the
Stove and cause a fire hazard or release toxic fumes.

Fuel should be stored in a dry place; wood should be dried for at least 1 year in the correct
conditions.

Do not store fuel within the installation clearances or within the space required for charging
and ash removal.

Wet wood may cause serious creosote, which may damage your flue system and even your
stove. Also the use of wet wood will result in poor performance. Therefore the use of wet
wood is strongly discouraged.
Lighting Your Boru Stove For The First Time
1. Only small fires may be lit for the first 3-4 fires to help with the curing process.
2. After each fire leave the stove cool down completely before lighting the next fire.
3. It is important to note that there may be an unpleasant odour and a small amount of
smoke for the first few fires this is nothing to be alarmed about it is just part of the curing
process. Keep the room well ventilated to help alleviate this.

Controlling Your Boru Stove
For your stove to burn correctly you need air to burn the fuel. The volume of air is controlled using the
lever to the right of the door of the stove.
The primary air, as the name suggests, is used for the initial burning of the fuel. The control for this is
the lever on the right hand side of the stove as you look at it. To operate this pull out lever for
increased airflow and push in lever for decreased airflow.
The settings of both of this air control very much depends on draft and local conditions and after a few
fires you should have a good idea of the best settings for your stove. The air control should be fully
opened when lighting the fire. Once the fire is established, the control may be adjusted as required.
Reducing the air intake will cause the stove to burn slower. This may cause some blackening of the
stove glass, but this should burn off once the stove is burning brightly again. It is recommended that
the stove be run at high output for at least 30 minutes each day to avoid tar and creosote buildup and
reduce the chance of a chimney fire.
22
Boru Stoves® BCMUS
SAVE THESE INSTRUCTIONS
Refueling

Before refueling increase the airflow (pull out primary and secondary air handles) this will
ensure that there is no build up of harmful gasses within the stove.

Care must be taken when refueling the stove. A protective glove or the multi tool handle
provided must be used as the handle on the body of the stove can get extremely hot. Also
use tongs when tending the fire.

Care must be taken not to stack the wood too high. The wood must not touch the overhead
baffle and airway.

Wood burns better on a bed of ash so the ash only needs to be removed occasionally.
Ash Removal

Your stove is fitted with a brick bed which has a trap door in the middle. To empty the ash
scrape the ash with the tool provided into the ash pan. When the ash pan is full remove it
using the multi tool provided.

You should always wear protective gloves when removing ash. If possible, this should be
done before lighting the stove when the ash is cold.

To remove the ash, open the stove door and use the operating tool provided to lift the ash
pan out of the stove. If possible, this should be done before lighting the stove when the ash is
cold. Even if the ash appears to be cold, it should be placed in a non-combustible container
as there may be hot ash in the center of the pile.

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 thoroughly cooled. Do not place any
other waste in the container.

This stove is not designed to operate with the door open. Always close the stove door when
you have taken out the ash tray and leave closed while disposing of the ash. Only reopen to
put ash pan back into the stove and close immediately afterwards.
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 local
dispersed, they should be retained in the closed container until all cinders have thoroughly cooled and
moved outdoors immediately. Do not place any other waste in the container.

Stove Maintenance
It is very important that your stove be checked regularly for the following:
1. Creosote: When wood is burned slowly, it produces tar and other organic vapours, which
combine with expelled moisture to form creosote. The creosote vapours condense in the
relatively cool chimney flue of a slow-burning fire. As a result, creosote residue accumulates
on the flue lining. When ignited, this creosote makes an extremely hot fire. Inspect and clean
chimney frequently – Under certain conditions of use, creosote buildup may occur rapidly. If
creosote has accumulated, it should be removed to reduce the risk of a chimney fire.
2. Establish a routine for the fuel wood burner and firing technique, Check daily for creosote
build-up until experience shows how often you need to clean to be safe. Be aware that the
hotter the fire the less creosote is deposited, and weekly cleaning may be necessary in mild
weather even though monthly cleaning may be enough in coldest months. Contact your local
municipal or provincial fire authority for information on how to handle a chimney fire. Have a
clearly understood plan to handle a chimney fire.
3. All firing and ash doors must remain closed during firing. All seals (door and window glass)
must be maintained in good working order.
4. THE USE OF SUBSTITUTE MATERIALS AND COMPONENTS MAY RESULT IN
POOR PERFORMANCE AND A DANGEROUS CONDITION. TO MAINTAIN YOUR
WARRANTY YOU MUST USE APPROVED REPLACEMENT PARTS.
The checks below should be carried out twice a year
1. Check for soot and creosote buildup and sign of joint damage. Do not use if flue pipe or
chimney is damaged. To check this, the top baffle must be removed by lifting it up and pulling
out. Clean the baffle before refitting. Do not light the stove until the baffle has been refitted.
Insulation above the baffle must be put back or replaced as necessary.
2. Make sure the glass is not cracked or chipped and that the rope has a good seal. Failure to
replace frayed rope will result in over firing.
3. Check that the stove door is tight and well-sealed when closed. Place a strip of paper into the
stove and close the door, try to pull out paper. You should feel some resistance to your pull
check several points around the door. If it pulls out too easily, replace the rope and seal in
place with a suitable high temperature sealant.

Cleaning the Glass
Generally the glass will clean itself when a good fire is established using the airwash system (left
lever). However there will be times when the glass has to be cleaned by hand. To do this use a soft
cloth and a nonabrasive cleaner. Never clean the glass when the stove is hot.
Do not use the stove with cracked or broken glass. If the glass breaks when the fire is lighting leave
the fire extinguish itself. Do not open the door until the stove is completely cool. Any broken glass
should be replaced by a qualified installer.
Glass For Your Boru Stove is 5mm Robax Schott Ceramic Glass
If handling glass whether broken or not - ALWAYS wear protective gloves.
Test and Repair of Door Gasket
Air leaks can be caused by low spots in the door gaskets. To locate such low spots, close each door
on a slip of paper and attempt to pull the paper free. If the paper slips out without tearing, the gasket
isn’t snug enough at that spot. If the seal cannot be improved by adjusting the door latch, try
shimming the gasket. Pack a small quantity of cement or a smaller diameter gasket into the channel
beneath the gasket to lift the main gasket and thereby improve its contact with the door frame.
If shimming does not improve the seal, replace the gasket following these steps:
1. Remove the original gasket by grasping an end and pulling firmly.
2. Wearing safety goggles use a wire brush or the tip of a screwdriver to clean the channel of any
remaining cement or bits of gasket.
Bricks
Your Boru stove contains high density vermiculite bricks. This increases the efficiency of
your stove by insulating the firebox which leads to better combustion which in turn creates
more heat. Bricks can and will crack! A cracked brick does not mean it has to be changed.
A cracked brick can last for years. A brick only needs to be changed when it starts to break
down (starts to crumble) or if a gap starts to appear in the crack.
