2. Installation instructions
2.1. Warning to the user
An incorrectly installed heating appliance can
cause serious accidents (chimney fires, burning of
plastic insulation materials, in partition walls, etc.).
The insulation of both the appliance and the exhaust
gas pipe has to be reinforced and done according to the
Standards and the Building Regulations for safety
reasons. The installation must be carried out according
to the Standards and the Building Regulations.
Failure to respect the mounting instructions leads to
engage the responsibility of the one doing the
installation.
The manufacturer's responsibility shall be limited to the
supply of the appliance.
2.2. Location of the unit
Ventilation :
For satisfactory appliance operation with a natural
draught, check that sufficient air for combustion is
available in the room.
Position of the unit :
For new installations, select a central position within the
house, to provide a good heat distribution around the
building.
The heat distribution towards the other rooms will be
made through the communicating doors.
These rooms must be in negative pressure or must
include ventilation gratings.
Floor and walls :
Make sure they are not combustible or covered with
combustible material (as per the Building regulations).
O t h e r w i s e i t m u s t n e c e s s a r y t o i n s t a l l a
non-combustible protection.
There must be a clearance of at least 150 mm at each
side of the appliance and at the back of the appliance
from a non-combustible wall.
This distance must be extended to a minimum
clearance of 350 mm from any combustible materials.
This measurement may be reduced to a minimum gap
o f
5 0
m m
w h e n
t h e
non-combustible wall is at
least 200 mm thick.
When using a single wall
flue pipe, there must be a
clearance (A) of at least
three times its diameter (B)
f r o m a n y c o m b u s t i b l e
materials.
If the appliance has to be
located in an opening, this
distance must be extended
to a minimum clearance (A)
of 375 mm from the pipe or
t h e s t o v e b o d y t o a n y
combustible materials.
Hearth
The appliance must stand
on a fireproof hearth.
The hearth must be made of
non-combustible material of
4
thickness 12 mm minimum (C). This may include the
thickness of a non-combustible floor.
The hearth must protrude at least 225 mm in front of the
stove and 150 mm each side.
If the hearth is constructed on timber, there must be a
clearance of at least 250 mm from the timber to the top
surface of the hearth.
2.3. Flue
The chimney must comply with Current Building
Regulations. If in doubt, consult your Dealer or local
Building Inspector.
Existing flue :
-
The flue must be in good condition and must provide
sufficient draught.
-
The flue must be suitable for the installation of solid
fuel burning appliances and comply with Current
Building Regulations.
-
The flue must be clean. It should be swept to remove
soot and dislodge tar deposits.
-
The flue must be well insulated. If the flue inner wall
surfaces are cold, a good thermal draw is impossible
causing condensation problems (tar formation etc) to
occur.
-
The flue must not be shared with other appliances.
-
The chimney must be at least 4.5 m (15 ft high).
-
In case of a flat roof or when the roof gradient is lower
than 15°, the stack must be 1,2 m (4 feet) high at least.
-
If the chimney has any down draught tendency, due to
its position in relation to nearby obstacles, then an
anti-down draught cowl must be installed on the
chimney or the chimney height must be increased.
-
If the decompression in the chimney is excessive, a
draught stabiliser must be installed.
Chimney to be built / Flue non-existent :
-
The flue must not be supported by the stove.
-
Consult a chimney specialist for advice on suitable
flue systems for solid fuel appliances.
