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. 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 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
