3.0 Requirements for
installation
3.1 Distance from the surround to a
wall made of a flammable material
Installation in front of a wall: See fig. 1C.
Corner installation: See fig. 1D.
N.B. When using a steel chimney the distance may be larger,
depending on the pipe’s placement.
When using a firewall
If the wall behind the product is bricked up with the same
thickness as a firewall the surround may be placed right up to
the firewall.
Standard firewall requirements
The firewall must be at least 100 mm thick and be made of brick,
concrete blocks or light concrete.
Other solutions may be recommended by your supplier.
N.B! It is illegal to use natural stone as a firewall.
The firewall shall be large enough such that the insert and flue
pipe do not come within 300 mm of flammable material.
3.2 Air circulation requirements
Air shall be allowed to circulate between the insert and the
brickwork.
The areas specified below for the air intake in the base and the
outlet at the top are minimum requirements. This is to ensure
that heat build-up in the surround is acceptable and so that there
is sufficient heat transmitted into the room.
Necessary air openings are:
Base: Minimum 350 cm
2
free opening.
Hood: Minimum 500 cm
2
free opening.
The openings required by the Jøtul FS 11 have been allowed for.
3.3 Floor coverage requirements
The Jøtul FS 11 has a flush-fitting base plate and therefore no
extra floor protection is required.
Any flammable flooring material must be removed from the area
under the fireplace and floor plate.
3.4 Standard front plate requirements
In front of the fireplace a plate made of steel or other non-
flammable material should be used.
Contact your local building authority regarding restrictions and
installation requirements.
3.5 Standard ceiling coverage
requirements
If the stove cowling is bricked up to the ceiling and the ceiling is
made of combustible material, on top of the warming chamber
and the cowling vents an extra ceiling panel must be installed
to avoid heating the ceiling.
For example use:
Rock wool 100 mm thick on top of a steel plate min. 0.9 mm.
Ensure airing out the top of the stove cowling – for example an
20 mm opening towards the ceiling.
4.0 Adjustment and
treatment
4.1 Painting the surround
All surrounds are delivered unpainted.
Painting may take place the day after installation. Use latex
paint. If a slight surface texture is desired mix a little tile cement
in with the paint.
4.2 Treating sheets of slate or marble
Remove all traces of glue and paint and wash the surface with
soap and water.
4.3 Cracks
After several month’s usage small cracks may appear in the joints
due to settling. These cracks can easily be repaired:
• Open up the cracks with, for example a screwdriver, in order
to give more space for the filler.
• Remove any dust with a vacuum cleaner.
• Inject an acrylic filler into the cracks and smooth over with
a wet soapy finger.
• After a couple of days the join may be painted.
