must be clean, leak-proof and without obstructions,
and must have a diameter of 150 mm.
• Any bends in the flue tube must not exceed 45
degrees.
• Ensure that the chimney tube can discharge the flue
gases adequately, properly and safely.
Supply of combustion air
The stove must have a sufficient fresh supply of
combustion air. To avoid draft, make if necessary an
extra air supply opening as close to the stove as possible.
An extra air supply opening is definitely required if:
• the room has a heat recovery system.
• the room has a central exhaust system.
• the same space has a cooker hood.
The air supply opening must be sealable if it goes through
a fire-resistant wall. If there are several heating devices
in the same room there must be enough air openings to
guarantee proper combustion.
With the Boreal you can also opt for an external air
supply connection to the bottom of the stove. The length
and the diameter of the air supply duct are important; the
maximum length of a 100 mm diameter air supply duct
is 1 meter and the duct can have one bend of 90°. If the
duct exceeds 1 meter you must increase its diameter.
Fire Safety
For reasons of fire safety is it important to observe the
instructions below before installing the stove.
1. The free distance from the fire-proof rear wall is at
least 10 cm in each rotated position.
2. Keep at least a distance of 80 cm between the stove
and combustible objects such as curtains, wooden
objects (cupboards and paintings) and glass objects.
Keep the same distance from the flue tube.
3. Wooden construction parts within the radiation
range of the stove (80 cm from the exterior of the
stove) must be covered with fireproof material.
4. If the flue tube goes through a ceiling and/or roof
that consist of flammable materials, the ceiling and
the roof must be covered with fireproof materials all
around (about 80 cm). Pay also attention to joisted
floor layers and any electric wiring.
5. Keep a distance of at least 50 cm (in all directions)
between the stove and supporting steel construc-
tion parts.
6. Shield off all combustible materials within a radius
of 80 cm from the stove openings with non-com-
bustible materials.
7. The wall behind the stove must consist of, or be
insulated with, fire-proof materials. The insulation
material must resist a temperature of 700 °C and
have a density of 80 kg/m3. Please see for insulation
materials table on page 26).
8. Avoid heat transmission when placing the stove.
Heat transmission of a burning stove can penetrate
the wall and even cause fire damage on the other
side of the wall. Prevention is better than cure.
Installation
The Boreal is tested in accordance with the international
EN 13240 standardization, and has an extra additional
standardization for optimally environment-friendly
heating devices related to flue gases (Section 15a B-Vg.
Des BmfWA). The stove can be connected to a flue tube
to which several stoves are connected. The Boreal must
never be inserted into a wall.
The heating device must be placed and connected by an
acknowledged installer and according to the installation
instructions given below. The national and local rules
and regulations for placing and using wood-burning
stoves are equally applicable. WANDERS does not give
any guarantee if the Boreal is connected or installed
incompletely or incorrectly.
Connecting the fireplace
Be sure that the floor is strong enough to hold the weight
of the hearth without problem.
Before mounting the hearth, follow the instructions
given in the previous chapter. Protect the floor when you
mount the stove, and mind your back.
1. Is the packing undamaged? If you detect any visible
damage, please notify the factory.
2. Is the chimney duct clean and open? (See the chap-
ter on 'Preparation'.)
3. Is the air supply duct clean and open? (See the
chapter on 'Preparation'.)
4. Are the fire safety requirements met? (See the chap-
ter on 'preparation'.)
5. Remove the screws for transportation safety.
6. Put the hearth in its position (Be sure not to damage
the floor and please mind your back while lifting!)
7. Secure the duct between the hearth and the exhaust
pipe. Connect it in the straightest possible way. The
flue gas duct must be made of at least 2 mm steel.
Please note: the duct may expand by about 1 cm
per meter of its length. Ensure that the discharge
duct does not get jammed between the mouth of
the pipe and the ceiling. If this is the case with the
rotating stove, it will be harder to turn the stove.
8. Connect any external combustion air supply. If you
have the Boreal on a support, you must first take
away the front cover.
9. Place the baffle plate into the baffle supports.
10. If you opted for the turn able model, you must
check whether the hearth can rotate smoothly. You
can check this by pulling the knob underneath the
hearth towards you and by turning the stove.
