Insertthecondensatepipe (wallduct accessory)
throughthewallduct(accessory)(usinglubricant)
and connect it to the condensate nozzle using the
enclosed plastic elbows.
“Wall duct installation instruction”
If the condensate pipe is not routed inwards, the front
and rear openings in the wall duct have to be sealed
with the enclosed plugs.

6.2 Connection to the heating circuit
1. Ifnowallductisused,routethexedpipingofthe
heating circuit outdoors below the frost line.
2. Flush the heating circuit thoroughly before con-
necting it to the heating system.
IMPORTANT
Damage to the copper pipes due to impermissible load!
► Secure all connections against twisting.
Cross-sections and lengths of the pipes for the
heating circuit are adequately dimensioned.
The free pressing of the circulation pumps at least
results in the minimum throughput required for the
device type ( “Technical data / scope of sup-
ply”, page 16).
The hydraulic system must be equipped with a
buertank,therequiredvolumeofwhichdepends
on your device type.
“Technical data / scope of supply”, page 16
The lines for the heating are fastened to the wall or
ceilingviaaxedpoint.
3. Insert the vent at the highest point of the heating
circuit.
Makesurethattheworkingoverpressure( “Tech-
nical data / scope of supply”, page 16) is complied
with. Attach the enclosed sealing plate into the recess
inthehousingoor.

4. Connectthedevicetothexedpipingoftheheat-
ingcircuitviavibrationdecoupling(stainlesssteel
corrugated pipes, accessory). You must install
them to prevent the transfer of structurally borne
soundtothexedpiping.
NOTE
If an existing system is being replaced, the
old vibration decoupling may not be reused.

6.3 Pressure safety
Equip the heating circuit with a safety valve and dia-
phragm expansion vessel in accordance with local
standards and guidelines.
