1. Remove the two push-out plates on top of the
convection box by tapping them loose with a
hammer.
2. Attach the two included connection collars (1)
with 125 mm diameter to the resulting openings
with the provided M8x16 bolts and M8 nuts.
3. Connect flexible piping of 125 mm diameter to
these collars and route them to the desired
areas.
4. Connect the flexible tubing to the outlet grates in
the rooms.
5. If desired, the front outlet opening can be closed
with the provided cover plate (2). Remove the
two screws at the top of the appliance and attach
the cover plate using these screws.
Building the new hearth
Inside the hearth you provide space for convection.
In this space the air must be able to move freely. It
must be possible for air to be sucked in for combus-
tion, and the air heated by the fireplace (the convec-
tion air) must be able to flow freely into the area to be
heated; see next figure.
When building the hearth, follow these instruc-
tions:
The top of the hearth must be closed airtight using
a cover plate of incombustible and heat-resistant
material.
The cover plate must be level and placed at least
30 cm below the flue opening in the ceiling.
If desired, an additional outlet grate can be fitted
at the top of the hearth, just below the cover plate.

Do not use combustible material in the hearth
space and prevent thermal bridging by using
materials that conduct heat.
Follow the instruction below when building the
hearth:
1. Lay the floor of the hearth.
Make sure the door of the appliance can
swing freely over the hearth floor.
2. Build the hearth up to the smoke dome.
Ensure that a clearance of 2 mm is main-
tained between the appliance and the
masonry to accommodate the thermal expan-
sion of the fireplace.
3. The inside of the hearth may, if desired, be
cladded with reflective, insulating material.
Additional cladding of the built-in space pre-
vents unnecessary thermal radiation to outer
walls and/or adjacent rooms. It also prevents
damage to the hearth wall insulation.
4. Build the rest of the hearth up to the flue opening
hole in the ceiling.
The masonry should not rest on the fireplace.
Use a support such as a steel beam. Leave a
clearance of at least 3 mm between the sup-
port and the appliance.
5. Close the built-in space with the cover plate.
6. Put an air grate below the cover plate to allow for
the ventilation of the appliance.
7. Make an opening above the cover plate in order
to prevent any pressure build-up.
The figure below provides an example of the placing
of a fireplace insert in a hearth which is done using
the instructions given above.
