2. Fit the two connection collars supplied with a
diameter of 125 mm on the resulting openings
using the M8x16 screws and M8 bolts.
3. Connect flexible tubing with a diameter of 125 mm
to the collars and route them to the rooms.
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 stove (the convection air) must
be able to flow freely into the space to be heated; see
next figure.
When building the hearth, follow these
instructions:
The top of the hearth must be closed airtight by
means of 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.
An additional outlet grate can be fitted at the top of
the hearth and just below the cover plate, if
desired.
Do not use combustible material in the hearth
space, and avoid the effect of thermal bridging
when using materials that conduct heat.
Follow the instructions 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 stove and the masonry to
accommodate the thermal expansion of the
stove.
3. The inside of the hearth may, if desired, be
cladded with reflective, insulating material.
