4.3 Air supply
Air must circulate between the cassette and the brickwork. The
convection chamber surrounding the cassette ensures that there
is a minimum air circulation around the cassette. It would be an
advantage to have several vents in the brickwork, in order to
improve heat emission into the room.
Connect flexible channels directly from the warm air adapters
on the top of the warming chamber and directly to the cowlings
vents.
This is a safety measure to prevent a build up of heat in the
surround, and also to ensure sufficient heat emission into the
room.
Warm air channels in the fireplace must be of non-flammable
material. The channels can be extremly hot, and it is very important
that these are not in touch with burnable materials.
Using a fireplace requires a plentiful supply of fresh air to the
room where the fireplace is installed. If the house is sealed, the
room must be equipped with additional fresh air supply through
vents, or through separate ducts directly to the fireplace. The fresh
air duchts should be as straight as possible. Fresh air ducts in the
fireplace must be of non-flammable material.
To prevent condensation in air duct that pass through heated
spaces, the duct must be insulated with 30 mm of mineralwool
covered with a moisture seel. It is important to seal carefully
around the pipe where it passes through walls or floors. Use
jointing compound.
4.4 Ceiling
Distance from warm air opening in the hood's top to a ceiling of
c0mbustible material: min 500 mm
4.5 Chimney
• The fireplace can be connected to a chimney and flue
pipe approved for solid fuel fired fireplaces 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
calculating the correct chimney cross-section.
• Several solid fuel fired fireplaces can be connected to the
same chimney if the chimney's cross-section is sufficient.
• 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.
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.
Warning! Weight from the fireplace must not be transferred to the
chimney. The fireplace must not interfere with the ability of the
chimney to move and it must not be fastened to the chimney.
Note: A guide is published by the British Flue and Chimney
Manufacturers' Association which contains general information
on chimneys and flues.

Recommended 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.
In case of chimney fire
• Close all hatches and vents.
• Keep the firebox door closed.
• Check the loft and cellar for smoke.
• Call the fire service.
• Before use after a fire an expert must check the fireplace in
order to ensure that it is fully functional.
4.6 Preparation
Make sure the cassette is not damaged in any way before
commencing the installation.
The product is heavy! Make sure you have assistance when
erecting and installing the fireplace.
The Jøtul C 21/Jøtul C 22 comes in two packages (the front frame
comes in a separate package) and includes a loose handle, a
shovel and a bag of supplies, as well as adapters for the flue
outlet and for the warm air distribution from the convection
chamber (fig. 3).
• After unpacking the cassette, remove the box with its contents
and possibly also the baffle plate and burn plates to make the
product lighter. See section about: Service.
Assembling the front frame
• Unscrew both hinges from the front frame (See Fig. 4).
• Hook these onto the fire box's hinges and mount the front
frame on the hinges.
• Then mount the brass knobs and the door-latch spring (Fig.
5 D)
• If the front frame has to be adjusted, turn to the chapter
entitled Service, and Fig. 8.
Adjusting the front frame (fig 8)
Before installation
• Open the inspection hatch on the left-hand side of the
cassette (fig. 8).
• Loosen the two large screws – 8 mm (A) and adjust with the
three (6mm) screws (B) to position the frame correctly.
• Fasten the screws tightly again.
After installation
In order to adjust the front frame, it must be opened first. Loosen
the two large screws – 8 mm– and adjust with the three (6mm)
screws. Fasten the screws tightly again.
4.7 Mounting
The cassette should be test assembled before connecting the
flue pipe. The flue pipe should be installed according to the
requirements of the individual case, depending on the size of
the fireplace. Your Jøtul-dealer/installer will be able to give you
advice and instructions.
• Make sure the bottom of the fireplace is even.
• Put cement around the edge of the flue outlet
(fig. 4A).
