For installation (top flue connection):
1. Define the position for the installation of
the appliance
2. Drill the wall for the passage of the air/flue
gas pipe according to the references
indicated in the figure, considering that
the horizontal sections of pipe must have
a downwards slope of around 3 mm per
metre of length, to prevent any rainwater
from entering the boiler.
3. Make a hole that is 10 - 20 mm greater
in diameter than the rated diameter of
the coaxial pipe used, to simplify its
installation.
4. If necessary, cut the end of the pipes to
measure, remembering that the outside
part of the pipes must protrude from the
wall by between 10 and 60 mm. Eliminate
any burrs from the cut.
5. Connect the pipes to the boiler, placing the
gaskets correctly, and seal the connections to
the wall using the special seal couplings.
For installation (back flue connection):
For direct back flue connection it is necessary
to use the optional kit 1KWMR04A, and it
is required to alter the fan direction inside
the boiler.
Follow carefully next procedure:

The total length in linear metres of the
concentric pipes must not exceed the maximum
length indicated in the table below, considering
that each bend gives rise to the reduction
indicated. For example, a D= 60/100 pipe
with 1 x 90° bend + 1 metre hori 2
x 45° bends + 1 metre horizontal, has a total
equivalent length of 4 metres.
