intense trial fire with newspaper and dry, small
kindling.
If there is new masonry then wait until the
masonry has dried sufficiently.
Drawing off convection air
The appliance is equipped with two additional con-
nections in order to transport convection heat to other
areas.There must be air grids in these areas. If you
wish to make use of this function, proceed as follows:
1. Remove the two push-out plates on top of the con-
vection box by tapping them loose with a hammer.
2. Fit the two connection collars supplied with a dia-
meter of 125 mm on the resulting openings using
the M8x16 screws and M8 bolts supplied.
3. Connect flexible tubing with a diameter of 125 mm
and route them to the desired areas.
4. Connect the flexible tubing to the outlet grates in
the rooms.
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 combustion, and
the air heated by the fireplace (the convection 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 maintained
between the appliance and the masonry to
accommodate the thermal expansion of the fire-
place.
3. The inside of the hearth may, if desired, be clad-
ded 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.
