Set-up and installation
4.7 Connect the condensate drain
The condensate in gas condensing technology has a
pH value
between 3.5 and 4.5
.
Connection
The condensate box is factory-assembled in the boiler cradle and
connected to the flue gas connecting piece of the boiler. The con-
nection to the wastewater network is designed for
HT piping
DN 40
.
Ɣ
Lay the condensate drain sloping down from the boiler so that
condensation will not accumulate in the flue gas manifold.
Ɣ
In order to avoid accumulation in the flue gas connection of
the boiler, make sure that no siphon is formed between the
condensate drainage hose and the connection with the
wastewater line.
Ɣ
Fill the condensate box with water in order to prevent flue gas
from escaping into the installation room. To do this, either:
– Open the boiler body and lift out the combustion chamber
insert (see section 9.2.5); top up condensate pipe using a
hose (see fig. 4-12) or,
– Unscrew the inspection lid of the connecting piece of the
flue gas pipe and fill the condensate box by using a hose
held in the flue gas pipe.
Ɣ
Check the condensate drain section for leakage.
4.8 Establish connection and electrical
equipment
4.8.1 Instructions concerning electrical connection
All electronic control and safety systems of the ROTEX A1 are
connected and tested. Modifications on the electrical installation
are dangerous and prohibited. The operator alone shall bear re-
sponsibility for any resulting damage.
A 3 m flexible cable is already connected inside the unit and
placed in the control panel on the connecting circuit board. Only
the external temperature sensor and other optional applications
(e.g. storage tank sensor, circulation pump) still have to be con-
nected to the boiler control panel.
4.8.2 Establishing the electrical connection
Ɣ
Check the supply voltage (
~230 V, 50 Hz
).
Ɣ
Disconnect the junction box of the domestic installation.
Ɣ
Connect the mains connection of the ROTEX A1 to the
junction box of the domestic insulation. Ensure that the
polarity is correct.
Ɣ
Restore power supply to the junction box of the domestic
electrical installation.

WARNING!
Live parts can cause an electric shock on contact and
cause fatal burns or injuries.
Ɣ
Before beginning work on live parts, disconnect
them from the power supply (switch off fuse, main
switch) and secure against unintentional restart.
Ɣ
The electrical connection should only be
performed by electrical engineers in compliance
with valid standards and guidelines as well as the
specifications of the energy supply company.
