Wood (split wood):
Recommended length: 30 cm
Diameter: Approx. 8 cm
Interval for adding wood: Approx. every 50 minutes
Fire size: 1.6 kg (nominal output)
Quantity required each time: 3 pieces
Nominal heat output is achieved when the air vent is open
approx. 40 % (fig. 4 A).
3.0 Installation
3.1 Floor
Foundations
You need to make sure the foundation is suitable for a stove. See
“2.0 Technical data” for specified weight.
Requirements for protection of wooden
flooring beneath the stove
Jøtul I
400
has a heat shield underneath to protect the floor from
radiated heat. The product can therefore be positioned directly
on a wooden floor that has been covered by a sheet of metal
or other non-inflammable material. Recommended thickness
minimum
0.9
mm and must cover the entire floor surface within
the surround.
It is recommended that flooring that is not attached to the
actual floor surface – “floating floors” – be removed beneath
the installation.
Jøtul recommends that any flooring made of combustible
material, such as linoleum, carpets, etc. should be removed from
under the floor plate.
Requirements for protection of inflammable
floors in front of the stove
The floor in front of the stove must be protected by a sheet
of metal or other non-inflammable material. Recommended
thickness is minimum 0.9 mm.
The front plate must comply with national laws and
regulations.
Contact your local building authorities regarding restrictions and
installation requirements.
3.2 Wall
Distance to inflammable wall protected by
insulation (fig. 1)
Insulation requirements50 mm
rock wool 120 kg/m
3
with
aluminium foil on one side.
Distance to inflammable wall protected by
firewall (fig. 1)
Requirements for regulation firewalls
The firewall must be a minimum of 100 mm thick and be made
of brick, concrete or lightweight concrete. Other materials and
structures with satisfactory documentation may also be used.
Contact your local building authorities regarding restrictions and
installation requirements.
Distance to non-inflammable wall (fig. 1)
“Non-inflammable wall” here means a non-bearing wall of
continuous brickwork/concrete.
Requirements for fireplace surround
Fireplace surrounds must be made of a non-inflammable
material.
Note that the entire back wall within the surround and other
adjacent areas using inflammable materials must be covered
with insulation/firewalls.
If the fireplace cowl is built up to the ceiling and the ceiling is of
inflammable material, extra panelling must be installed above
the top of the heating chamber and above the cowl’s vents in
order to prevent the ceiling becoming hot.
Use for example:
Rock wool 100 mm thick on a steel plate min. 0.9 mm.
Ensure there is adequate ventilation at the top of the fireplace
cowl – e.g. a gap towards the ceiling, or approx. 5 cm
2
opening
(fig. 2 )
.
NB! Remember that it must be possible to sweep and inspect
the installation.
3.3 Air supply (fig. 2)
Air must flow between the insert and the brickwork, and it is
extremely important that there should be an unimpeded air
supply to the air vents at both the top and bottom of the insert.
The air inlets specified in the text are minimum requirements.
Necessary circulated air:
Base: Minimum 500 cm
2
free opening.
Top:
Minimum 750 cm
2
free opening.
This is to ensure that the build-up of heat inside the surround
does not become too great and that heat output into the room
is adequate.
If the building is poorly ventilated, the room should be furnished
with an additional fresh air supply by means of vents, or a
separate duct.
The fresh air duct should be as straight as possible. Ducts in
the room where the stove is installed must be made of
non-
inflammable material.
The product can be supplied with outside air (kit for outside air
connection is available as an optional extra).
3.4 Ceiling
Jøtul I
400
can be fitted with the top edge of the hot air opening
at least 400 mm below a ceiling of inflammable material.
3.5 Chimney and flue pipe
• The stove can be connected to a chimney and flue pipe
approved for solid fuel fireplaces with flue gas temperatures
as specified in
“2.0 Technical data”
.
• The cross section of the chimney must be at least that of the
flue pipe. Use
“2.0 Technical data”
to calculate the correct
chimney cross section.
