ENGLISH

Wood consumption

Jøtul F 

100 

has a nominal heat output of 

5,0

 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: 20 - 40 cm

Diameter: 2 - 5 cm

Amount per fire: 6 - 8 pieces

Firewood (split logs):

Length: 40 cm

Diameter: Approx. 8 cm

Intervals for adding wood: Approx. every 60 minutes

Size of the fire:  1,8 kg

Amount per load:  2 pieces.

Nominal heat emission is achieved  when the air vent is open 

approximately 50%.

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 

100

 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.

3.3 Ceiling

Jøtul F 

100

 may be assembled with the upper edge of the hot 

air aperture min 

1200 mm

 beneath the ceiling of the flammable 

material

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» 

to calculate the correct cross-section of the chimney. 

•  Several solid fuel-fired fireplaces can be connected to the 

same chimney if the cross-section of the chimney is adequate.

• 

Connection to the chimney must be carried out in accordance 

with the installation instructions from the supplier of the 

chimney. 

•  Before making a hole in the chimney the fireplace should be 

test-mounted in order to correctly mark the position of the 

fireplace and the hole in the chimney.  See 

fig. 1

 for minimum 

dimensions. 

•  Ensure that the flue pipe is inclined all the way up to the 

chimney.

•  Use a flue pipe bend with a sweeping hatch that allows it 

to be swept.

Be aware of the fact that connections must have a certain 

flexibility in order to prevent movement in the installation 

leading to cracks.

 N.B. A correct and sealed connection is very 

important for the proper functioning of the product.

The chimney draught, see «2.0 Technical data». If the draught is 

too strong you can install and operate a flue damper to control 

the draught.

3.5 Assembly prior to 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 

erecting and installing the fireplace.

1.  The product is delivered in a single packing case where the 

smoke outlet, ash lip and door bolt knob must be assembled. 

2.  Once you have unpacked the product, remove all loose parts. 

Check that the product does not have any visible damage and 

that the operating handles work.

N.B. The top plate only rests on the product and shall not be 

attached to it. 

Rear mounted flue pipe

If the flue pipe is to be rear mounted do the following:

1.  Lift off the top plate.

2.  Cut out a hole in the heat shield at the back for the flue pipe 

(fig. 3)

.

3.  Unscrew the two screws holding the cover for the rear outlet 

from the inside. (Hold the cover when removing the last 

screw) 

(fig. 5A).

4.  Fasten the cover on the top plate.

5.  Connect the smoke outlet to the rear plate. 

6.  Place the top plate back in position.

7.  Install the ash lip by hanging it under the door. 

8.  Screw the door knob on the handle. (Place the white washer 

between the handle and the knob.)

9.  Remove the protective paper from the gasket and fasten it 

around the outside of the flue pipe.

10.  Mount the flue pipe into the flue outlet.

N.B. It is important that the joints/flue pipes are completely 

sealed. Air leaks can prevent the flue pipe from functioning 

properly.

Top mounted flue pipe

If the flue pipe is to be top mounted do the following:

1.  Attach the flue outlet to the top plate using the two screws. 

Fig. 4A.

2.  Install the ash lip by hanging it under the door. 

3.  Screw the door knob on the handle. (Place the white washer 

between the handle and the knob.)

4.  Remove the protective paper from the gasket and fasten it 

around the outside of the flue pipe.

5.  Mount the flue pipe into the flue outlet.

N.B. It is important that the joints/flue pipes are completely 

sealed. Air leaks can prevent the flue pipe from functioning 

properly.

3.6 Control of functions
