4.5.7 Connection of the pipes
On of the boiler installation the pipelines are connected
directly to the feed and the return connectors. Please
note the designations for the pipeline connectors in chap-
ter 3.3.
4.5.8 Condensate draining and neutralisation
The condensate from heat output gas boilers is to be
transferred to the public drainage system or an own
drainage system and where prescribed, neutralised prior
to introduction.
Please comply with the instructions of the re-
sponsible local waste water authorities.
In Austria:
Please note the planning directives for heat output firing
systems in the Austrian Standard H 5152 and in particular
the ÖVGW (G 41).
It is important, already prior to planning and executing
the boiler system to contact the responsible authorities to
plan and execute the condensate drainage according to
regulations.
The siphon drain pipe must be directed into
a funnel.

WARNING
The installation of the gas pipeline and first
placing in operation must be carried out by a
recognised expert.
The provisions of the relevant national regulations
(SVGW directives, ÖVGW directives, DVGW-TRGI 86-
96, DIN 4750) as well as local regulations of gas supply
en terprises should be observed.
A manually operated shut-off device (gas shut-off cock)
in accordance with the local regulations is to be installed
directly before the boiler.
Please ask your local gas supply authority whether it is
necessary for an approved gas filter to be installed be
-
tween the manual shut-off valve and the boiler, to elimi
-
nate faults due to particles carried in the gas.
In Germany some regional building regulations require
the installation of a thermally activated shut-off valve di-
rectly before the boiler. Please enquire at your local re-
gional planning office.

WARNING
It is imperative to check all gas-carrying pipe-
lines for leaks before initially placing the boil-
er in operation.

Electrical connection
WARNING
The heat generator can only be de-energised
by disconnection from the mains (e.g. all-
pole switch).
WARNING
All electric power supply circuits must be
switched off before accessing the terminals.
WARNING
The electrical connection (sensors, pumps
and all other devices and components to be
connected) must be connected in accord-
ance with the applicable standards of nation-
ally or internationally recognised profession-
al associations.
