Schematic layout of the factory-supplied gas components
to be executed on-site by the
installation company
The installation of the gas
connection may only be executed
by authorised technicians
(authorised by the municipal
gas supplier) in observance of
the applicable provisions for the
respective gas type.
The cross-section of the ductwork
should be determined according
to the connection value of the
unit, the total output resistance as
well as the amount of gas supply
pressure.
The necessary gas supply pressure
(depending on gas type) should be
ensured on site.
The necessary amount of gas and
the necessary gas pressure must
be continuously available during
operation of the unit according to
its output.
The unit connection takes place
through an R 3/4“ or R 1“
external thread connection.
The gas supply should be executed
with a suitable, removable screw
connection free of voltage and
vibration.
The components described in the
applicable gas guidelines as well as
the locally required components in
the gas supply, such as gas pressure regulators, isolation
devices, etc. are not included in
the scope of delivery and must be
provided by the customer.
Installing a high-output compatible
gas filter without pressure
regulator is also recommended,
because the filter area of the serial
filter installed above the gas valve
is limited.
The applicable standards allow a
maximum pressure of 60 mbar in
the heating room; higher pressure
values must be reduced prior
to entrance to the heating or
installation room of the unit.
Prior to the initial commissioning,
the gas supply line must be
thoroughly cleaned and bled
through appropriate measures.
It must be ensured that the
connection of the unit to the gas
supply line is executed gas-tight.
All screw connections of the
unit and the gas supply must be
inspected for leakage integrity.
With use of leak detection sprays,
they must correspond to DIN
30657 (non-corrosive).
We reserve the right to modify the dimensions and constructional design as part of the ongoing technical development process.
ATTENTION
Installation work on the gas
system and the supply lines
may only be conducted by
licensed technicians.
