Air/flue pipes that can be connected
▶
When installing the air/flue pipe, observe the provisions
of the applicable national regulations.
Note
All products feature an 110/160 mm diameter

5.3.2
Installing the air/flue pipe
Caution.
Risk of poisoning due to escaping flue
gas.
Mineral-oil-based greases can damage the
seals.
▶
Instead of grease, use only water or com-
mercially available soft soap to aid install-
ation.
Danger!
Risk of personal injury and material dam-
age due to unapproved air/flue pipes.
Vaillant boilers are certified only with Vaillant
original air/flue pipes. The use of other ac-
cessories may cause personal injury and ma-
terial damage, as well as operating faults. For
installation type B23P, third-party accessor-
ies are also permitted (see the technical data
in the appendix).
▶
Only use Vaillant original air/flue pipes.
▶
If third-party accessories are permitted
for B23P, ensure that the flue pipe con-
nections are properly routed, sealed and
secured against slipping out.
1.
Install the flue pipe using the installation manual.
2.
When installing the air/flue pipe, observe the provisions
of the applicable national regulations.
3.
Route the flue pipe with a downward gradient so that
the condensate that accumulates can easily flow into
the condensate trap provided for it.
5.4
Electrical installation
Only qualified electricians may carry out the electrical install-
ation.
Danger!
Risk of death from electric shock!
Power supply terminals L and N remain live
even if the on/off button is switched off:
▶
Disconnect the product from the power
supply by switching off all power supplies
at all poles (electrical partition with a con-
tact gap of at least 3 mm, e.g. fuse or cir-
cuit breaker).
▶
Secure against being switched back on
again.
▶
Wait for at least 3 minutes until the capa-
citors have discharged.
▶
Check that there is no voltage.
