Fix the cable with cable ties to the cable tie mountings.

NOTICE

Make sure to select and install the safety thermostat
according to the applicable legislation.

In any case, to prevent unnecessary tripping of the safety
thermostat, it is recommended that …

▪ … the safety thermostat is automatically resettable.

▪ … the safety thermostat has a maximum temperature

variation rate of 2°C/min.

▪ … there is a minimum distance of 2 m between the

safety thermostat and the motorised 3‑way valve
delivered with the domestic hot water tank.

▪ … the safety thermostat setpoint is at least 15°C

greater than the maximum leaving water temperature
setpoint.

INFORMATION

After it is installed, do NOT forget to configure the safety
thermostat. Without configuration, the indoor unit will
ignore the safety thermostat contact.

7.11

Connecting the gas piping

7.11.1

To connect the gas pipe

Connect a gas valve to the 15 mm gas connection of the gas
boiler and connect it to the field pipe according to local
regulations.

Install a gas mesh filter in the gas connection if the gas may be
contaminated.

Connect the gas boiler to the gas supply.

Check all parts for gas leaks on a pressure of maximum
50 mbar (500 mm H

O). There may be no stress on the gas

supply connection.

7.12

Connecting the boiler to the flue
gas system

The gas boiler is designed ONLY for operation independent of room
air.

The gas boiler is delivered with a 60/100 concentric flue gas/air
intake connection. An adapter piece 80/125 concentric connection is
also available.

The concentric adapter piece is equipped with a measuring point for
the gas exhaust and one for the air intake.
