ENGLISH
Air must flow between the insert and the brickwork, and it is
extremely important that there is an unimpeded air supply to
the air inlets.
The air inlet dimensions specified in the text are minimum
requirements.
Required air vent sizes (for air circulation):
Base: Minimum of 750 cm
2 free opening.
Top: Minimum of 1000 cm 2 free opening.
This is a safety measure to ensure that the build-up of heat inside
the surround does not become too great and that the output of
heat to the room is adequate.
If the house is poorly ventilated, the room must be fitted with an
additional supply of outside air, e.g. by means of a separate duct
under the fireplace. The outside air duct should be as straight
as possible and must be made of a non-inflammable material.
It must be possible to close the ducts with a damper in order to
keep out cold air when the stove is not being used.
3.4 Ceiling
The fireplace can be fitted with the top edge of the hot air
opening of the surround at least 600 mm below a ceiling of
inflammable material. Ensure there is adequate ventilation in
the top of the cowl – e.g. a gap under the ceiling.
3.5 Chimney and flue pipe
• The fireplace must only be connected to a chimney and
flue pipe approved for solid fuel fireplaces with flue gas
temperatures as specified in «2.0 Technical Data».
• The cross-section of the chimney must be designed to fit the
fireplace. Use «2.0 Technical Data» to calculate the correct
chimney cross-section.
• The chimney must be connected in accordance with the
installation instructions of the chimney supplier.
• Before a hole is made in the chimney, the product 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.
• Make sure that the flue pipe rises all the way up to the
chimney.
• With a rear outlet, use a flue pipe bend with a sweep hatch
to allow sweeping.
• Please note that it is extremely important for connections to
have a degree of flexibility. This is to prevent any movement
in the installation leading to the formation of cracks.
• For recommended chimney draught, see «2.0 Technical Data».
For flue pipe dimensions with the relevant cross-section, see
“2.0 Technical Data”.
NB! The minimum recommended chimney length is 3.5 m from
the flue pipe insert. If the draught is too strong, a flue pipe
damper can be installed and used to reduce the draught.
Weight must not be transferred from the fireplace structure to the
chimney. The fireplace structure must not hinder the chimney’s
ability to move, and must not be anchored to the chimney.
3.6 Preparation/installation
NB: Check that the fireplace is undamaged before installation
begins. The product is heavy! Ensure you have help when
positioning and installing it.
After unpacking the insert take out the box with contents. To
make the product lighter, remove the door.

3. To make the installation easier, remove the burn plates (fig.
3 B-G/F), baffle plate (fig. 3 c-A), exhaust deflector (fig. 3 C-B),
log retainer (fig. 3 B-C), inner bottom (fig. 3 B-D), and grate
(fig. 3 B-E). See section “4.1 Replacing the burn plates, baffle
plate and exhaust deflector”.
