Operating tips

According to the Pressure Equipment
Directive 97/23/EC, a steam boiler
category IV may only be taken into
use when the relevant authority has
granted permission for the installation
of the system, and an authorised
expert has tested the system.
The system must be commissioned by
the system installer or a qualified per-
son authorised by the installer as well
the relevant expert.
Record all actual values in a commis-
sioning/service report. These values
must be confirmed by the expert and
the system user.
According to the Pressure Equipment
Directive 97/23/EC, hot water boilers
category IV may only be operated,
supervised and maintained by a
trained boilerman.

Operational checks

Danger
Boiler components that are not
thermally insulated can be sub-
ject to high temperatures that
can result in burns.
Take care with hot surfaces.
Subject to the safety equipment fitted
and the details in the permit certifi-
cate, either monitor the correct boiler
operation constantly, every 24 hours
or every 72 hours.

Operating information

The relevant authority may grant,
upon application, permission to oper-
ate the boiler without permanent
supervision, subject to it being
equipped in accordance with EN
12953 part 6.
In systems comprising several boi-
lers, of which one is constantly used
as standby boiler, only change the
operation over in longer intervals, e.g.
during the annual inspection of the
total system.
We would recommend that you oper-
ate the boiler constantly at the
required operating pressure and tem-
perature.
The continued boiler operation is still
advantageous, even if no heat is
drawn off for a longer period of time.
Determine the extent of checks
required in accordance with TRD 601,
sh. 1, section 7 [or local regulations].
Test the chemical composition of the
boiler water and feedwater constantly
in accordance with EN 12953 part 10
and VdTÜV datasheet 1466 [or local
regulations].
Carry out the following checks daily
or every 72 hours, subject to boiler
version and the manufacturer's speci-
fication (see also TRD 601, sh. 1):
& Blow down the boiler (only for boi-
lers without automatic facility;
briefly open the valve two or three
times at operating pressure).
& Check the water level limiter.
& Check the feed and boiler water.
