Wood consumption
Jøtul F 400 has a nominal heat output of 7,5 kW. Use of
wood, with nominal heat emission: Approx. 1,8 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: 30 - 40 cm
Diameter: 2-5 cm
Amount per fire: 8 - 10 pieces
Firewood (split logs):
Length: 30 - 40 cm
Diameter: Approx. 8 - 10 cm
Intervals for adding wood: Approximately every 45 minutes
Size of the fire: 2,0 kg
Amount per load: 2 - 3 pieces
Nominal heat emission is achieved when the air vent is open
approximately 40%.
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 400 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 authority regarding restrictions and
installation requirements.
