ENGLISH
Wood consumption
Jøtul F 373 has a nominal heat output of 5,5 kW. Use of
wood, with nominal heat emission: Approx. 1,9 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 cm
Diameter: 2-5 cm
Amount per fire: 6-8 pieces
Firewood (split logs):
Length: Ca 20 - 30 cm
Diameter: Approx. 8 cm
Intervals for adding wood: Approximately every 45 minutes
Size of the fire: 1.4 kg
Amount per load: 2 pieces
Nominal heat emission is achieved when the air vent (fig. 12 A)
is open approximately 100% and the handle for the ignition vent
pulled out approximately 1-2 cm (fig. 12 B).
2.1 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.
Combustible floor protection
Jøtul F 373 has a heat shield underneath which protects the base
from radiation. The product has an integrated floor protection
and may therefore be placed directly on a wooden floor.
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 (see fig. 2)
The front plate must be in accordance with national laws and
regulations.
Contact your local building authority regarding restrictions and
installation requirements.
2.2 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.
2.3 Ceiling
There must be a minimum distance of 1000 mm to a combustible
ceiling above the fireplace.

3.0 Installation
N.B. Check that the fireplace is free of any damage prior to
commencing installation.
The product is heavy! Make sure you have assistance when
installing the fireplace.
3.1 Prior to installation
1. When the product is unpacked, the burn plates, baffle plate,
exhaust deflector, base plate, ash pan and riddling grate are
removed. Also remove the small side burn plates and gasket
for flue pipe which are in the ash pan.
2. Lift off the top plate with the top grid (fig. 7 A) and bowl (fig. 7 B).
3. Check that the operating handles work.
4. Unscrew the screws (fig. 6 C).
5. If the rear flue pipe outlet is used, first drill holes (fig. 5 A)
in the cut-out covers for the flue pipe. Use the cardboard
packaging to protect the bottom plate from damage. Place
the wooden block that holds the exhaust deflectors in
position so that the side plates are supported when the cut-
out covers are removed (fig. 5 B).
Supply of external air
With F 373 it is possible to draw external air directly into the
product through the base/pedestal, or through a flexible supply
hose from outside/chimney* and to the outlet of the product
(fig. 4C).
* This shall only apply if the chimney has its own duct for external air.
3.2 Assembly
Jøtul F 373 (fig. 4 and 6)
Important! If the rotating set is to be assembled, this must be done
now. See assembly instructions which accompany the rotating set.
1. Adjust the product with the help of the 3 adjusting screws
(fig. 6 A).
2. If the external air supply via the external air vent is to be used,
the flexible hose, 100 mm diameter, is connected to the vent
on the product (fig. 4C) now.
3. Push the handle in the external air vent to the foremost
position (fig. 4D).
4. Fasten the hose to the external air vent with the aid of a
hose clip. N.B. Make sure that the hose is long enough to
avoid any joints.
5. If the external air is to be supplied through the floor, place the
flexible gasket (fig. 6 B) around the hose, 100 mm diameter,
which is drawn through the hole in the floor. Note! The hole
is in the center of the pedestal/flue pipe.
6. Push the handle in the external air vent to the rear position
(fig. 4E).
7. Place the product directly above the external air supply.
Important! Check that the handle in the external air vent is in
the foremost position if the external air is not to go through
the pedestal.
3.3 Chimneys and flue pipes
• The fireplace can be connected to a chimney and flue
pipe approved for solid fuel fired appliances with flue gas
temperatures specified in «2.0 Technical data".
• The chimney's cross-section must be at least as big as the
flue pipe's cross-section. See «2.0 Technical data» when
