3.0 Installation
3.1 Floor
Foundation
You need to make sure the foundation is suitable for a fireplace.
See “2.0 Technical Data” for specified weight.
Requirements for protection of wooden
flooring beneath the fireplace
The Jøtul I
570 has a heat shield underneath to protect the floor
from radiated heat. The product can therefore be positioned
directly on a wooden floor that is covered by a sheet of metal or
other non-inflammable material. The recommended minimum
thickness is 0.9 mm. The plate must cover the entire floor surface
within the surround.
We recommend the removal of any flooring that is not attached
to the foundation (“floating floors”) beneath the installation.
Any floor covering of inflammable material, such as linoleum,
carpets, etc. must be removed from under the floor plate.
Requirements for protection of inflammable
floors in front of the fireplace
The floor in front of the fireplace must be protected by a sheet
of metal or other non-inflammable material. The recommended
minimum thickness is 0.9 mm. The floor plate must comply with
national laws and regulations.
Contact your local building authorities regarding restrictions and
installation requirements.

firewall (Fig. 1)
Requirements for regulation firewalls
The firewall must be at least 100 mm thick and made of brick,
concrete or lightweight concrete + 50 mm insulation. 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 and, if any, side walls within the
surround must be covered with insulation/firewalls.
If the 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 in the top of the cowl – e.g. a gap
under the ceiling.
NB: Remember that it must be possible to sweep and inspect
the installation.
