Installing and connecting the air/flue pipe

1.

You can find out which air/flue pipes may be used by
consulting the enclosed set-up instructions for the
air/flue system.

2.

Observe the information on positioning the air/flue ter-
minal.

Condition

: Installation in damp rooms

You must connect the product to a room-sealed air/flue
system. The combustion air must not be taken from the
installation site.

3.

Install the air/flue pipe using the set-up instructions.

7.9

Electrical installation

Only qualified electricians may carry out the electrical install-
ation.

The product must be earthed.

Danger!
Risk of death from electric shock!

The power supply terminals L and N remain
live even if the product is switched off:

Switch off the power supply.

Secure the power supply against being
switched back on.

Carrying out the wiring

Caution.
Risk of material damage caused by incor-
rect installation.

Mains voltage at incorrect terminals and plug
terminals may destroy the electronics.

Do not connect any mains voltage to the
eBUS terminals (+/-).

Only connect the power supply cable to
the terminals marked for the purpose.
