Installation and maintenance instructions ecoTEC plus 0020214491_01
▶
Install the enclosed condensate drain pipework (hose)
(1)
.
Note
If the length of the enclosed hose is not suf-
ficient, use only pipes that are made from
acid-resistant material (e.g. plastic) for the
condensate drain pipework and also for the
waste-water piping.
▶
Suspend the condensate drain pipework above the prein-
stalled tundish

Installing the air/flue pipe
1.
You can find out which flue pipes may be used by con-
sulting the enclosed flue pipe installation manual.
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.
2.
Install the flue pipe using the installation manual.
5.4.1
Information on installing the B23
A flue gas pipe in accordance with unit type B23 (open-flued
gas-fired wall-hung boilers) requires careful planning and im-
plementation. During planning, observe the technical data for
the product and refer to the recognised rules of technology.
5.4.2
Information and specifications for installing
the B23P
The flue gas system must at least correspond to the clas-
sification T 120 P1 W 1 in accordance with EN 1443. The
maximum pipe length must be calculated based on the per-
missible pressure difference in the technical data.
The maximum pipe length (straight pipe only) corresponds to
the maximum permitted flue gas pipe length without any el-
bows. If elbows are used, the maximum pipe length must be
reduced in accordance with the dynamic flow characteristics
of the elbows. Elbows must not be connected directly after
one another as this method dramatically increases pressure
losses.
In particular, if the flue pipe is installed in cold rooms or out-
side of the building, the freezing point on the surface of the
inside of the pipe may be reached. A proven design in ac-
cordance with EN 13384-1 for a maximum boiler load at a
flue gas temperature of 40 °C must be used to prevent this
problem. The product must not be connected to a cascade
flue gas installation that is being used by other units.
▶
Observe the applicable international, national and local
regulations for flue gas systems, in particular for installa-
tions in living rooms. Inform the operator how to correctly
operate the product.
5.5
Installing and connecting the flue pipe
1.
You can find out which flue pipes may be used by con-
sulting the enclosed flue pipe installation manual.
2.
Observe the information on positioning the opening
for the flue pipe. This information can be found in the
appendix.
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.
3.
Install the flue pipe using the installation manual.
5.6
Electrical installation
Danger!
Risk of death from electric shock as a res-
ult of an improper electrical connection!
An improper electrical connection may neg-
atively affect the operational safety of the
product and result in material damage or per-
sonal injury.
▶
Only carry out the electrical installation if
you are a trained competent person and
are qualified for this work.
▶
Observe all applicable laws, standards
and directives in the process.
▶
Earth the product.
Danger!
Risk of death from electric shock!
Touching live connections may cause seri-
ous personal injury. Since mains connection
terminals L and N also remain live even if the
boiler main switch is turned off:
▶
Switch off the power supply.
▶
Secure the power supply against being
switched on again.
