Example of a vertical duct route
• Apply the seal to the coaxial vertical
adaptor (O);
• Carefully insert the O- ring (J) into the
inside part of the vertical adaptor;
• Put the vertical adaptor on the boiler’s and
fan’s outlets;
• Insert the coaxial extension (M) into the
vertical adaptor;
• For passage through the roof cover,
use either special roof tiles (so-called
“ventilation tiles”) or a roof flashing
custom-made by a tinsmith;
• The coaxial extension duct protruding
above the roof should be terminated with
a coaxial (“Meindinger”) head. Instead of
the extension duct and head, a vertical
terminal (L) is better to use as the nicer
top part.
• Attach a condensate-drainage part (tube,
hose, etc. – not included in the delivery)
to the condensate outlet of the vertical
adaptor;

Electrical connection of the boiler to the
power grid is by three-wire cord without
plug. The socket for the plug must comply
with the relevant standard and have the
grounding pin connected to a PE or PEN
cable (yellow-green).
The boiler must be connected to the
protective grounding wire; the electrical
plug in the socket must always be
accessible without obstacles. Use of
adaptor plugs, extension cords, etc. is
prohibited. The boiler is protected by tube
fuse 125 mA/250V placed on PCB.
Only a person with adequate electrical-
engineering qualifi cations can be allowed
to install the socket and the thermostat
(thermostat installation requires utilization
of the boiler’s internal electric cabling); the
same requirements apply to servicing the
electric part. Before any work commences
on the electrical part, the boiler’s cord must
be unplugged.
Only no-voltage thermostats or regulators
can be used for regulating the boiler, i.e.,
they must not bring in any foreign voltage.
The minimum requirements for the
regulator’s contacts: 24 V / 0.1 A, A.C.
The room thermostat is connected to the
boiler with a two-wire cable, with copper
wires of a recommended cross-section
between 0.5 and 1.5 mm

The connecting cables of the room
thermostat should not be led parallel to
other cables or through premises with high-
power electric motors (or electric welding
machines., etc.)
The terminal board for connections of the
room thermostat is inside the boiler, on
the bottom. It is accessible after removing
the front cover panel and tilting the control
panel out.
