The top of the convection space must be closed
airtight by means of a closing 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.
Air inlet grates must be fitted at the bottom of the
hearth to allow ambient air to flow in. The minimum
air inlet vent is 250 cm
sufficiently ventilated, you must provide for outside
air to be allowed in by means of the outside air
connection kit or an optional adjustable damper.
Air outlet grates must be fitted at the top of the
hearth and just below the cover plate. The
minimum air outlet opening is 500 cm
The inlet and outlet grates are available as
options.
Do not use combustible material in the
convection space, and avoid the effect of
thermal bridging when using materials that
conduct heat.
Follow the instructions below when building the
hearth:
1. Build the base of the hearth and fit the air inlet
grates into the masonry.
You can place the air inlet grates on all sides of
the base.
Make sure the door of the appliance can swing
freely over the hearth floor.
2. Build up the hearth up to the smoke dome.
Ensure that a clearance of 2 mm is maintained
between the stove and the masonry to
accommodate the thermal expansion of the
stove.
3. The inside of the convection space may, if
desired, be cladded with reflective, insulating
material.
Additional cladding of the convection space
prevents unnecessary thermal radiation
towards outer walls and/or adjacent rooms. It
also prevents damage to the insulation in the
walls of the hearth.

4. Build the rest of the hearth up to the flue gas hole
in the ceiling.
The masonry may not rest on the stove. Use a
support such as a steel beam. Leave a
clearance of at least 3 mm between the
support and the appliance.
5. Close the convection space with the cover plate.
6. Put the air outlet grates under the cover plate.
7. Make an opening above the cover plate in order to
prevent any pressure build-up.
The figure below shows an example of the placing of a
stove in a hearth built in accordance with the
instructions given above.
