Jøtul F 3 Montageanleitung Mit Technische Daten Seite 15

Wood consumption
Jøtul F 3 has a nominal heat output of 6,0 kW. Use of wood,
with nominal heat emission: Approx. 2,0 kg/h. Another
important factor for proper fuel consumption is that the
logs are the correct size. The size of the logs should be:
Kindling:
Length: 20 - 30 cm
Diameter: 2 - 5 cm
Amount per fire: 6 - 8 pieces
Firewood (split logs):
Length: 30 cm
Diameter: Approx. 8 cm
Intervals for adding wood: Approx. every 60 minutes
Size of the fire: 2 kg
Amount per load: 2 pieces.
Nominal heat emission is achieved when the air vent is open
approximately 100%.
3.0 Installation
3.1 Floor
Foundations
It must be ensured that the foundations are dimensioned for
the fireplace. Cf. «2.0 Technical data» for specification of weight.
It is recommended that flooring which is not fastened to the
foundations – so-called floating flooring – is removed during
installation.
Requirements for protection of wooden
flooring
Jøtul F 3 has a heat shield underneath which protects the floor
from radiation. The product can therefore be placed directly
on a wooden floor that is covered by a metal plate or other
suitable, non-inflammable material. The recommended minimum
thickness is 0,9 mm.
Any flooring made of combustible material, such as linoleum,
carpets, etc. must be removed from under the floor plate.
Requirement for protecting combustible
flooring in front of fireplace
The front plate must be in accordance with national laws and
regulations.
Contact your local building authorities regarding restrictions and
installation requirements.
3.2 Walls
Distance from the wall of flammable
material – cf. fig. 1
The fireplace is authorised for use with an uninsulated flue
with the distances to the wall of flammable material as shown
in fig 1.
Distance to the flammable wall protected by
a firewall
Firewall requirement
The firewall must be at least 100 mm thick and be made of brick,
concrete-stone or light concrete. Other materials and structures
with satisfactory documentation may also be used, e.g. Jøtul
Brannpanel.
3.3 Ceiling
There must be a minimum distance of 1000 mm to a combustible
ceiling above the fireplace.
3.4 Chimneys and flue pipes
• A chimney can be linked to the fireplace and flue approved
for solid fuel-fired fireplaces with a flue gas temperature as
specified in «2.0 Technical data».
• The cross-section of the chimney must be at least equal to
the cross-section of the flue. Please use «2.0 Technical data»
