Servicing/cleaning instructions and note on disposal of unwanted equipment
Servicing
Servicing of heating systems is required
under current heating system regula-
tions and standards (DIN 4755, DIN
4756 and DIN 1988-8).
Regular servicing of the heating system
will ensure troublefree, energy-saving
and environmentally friendly heating.
We strongly advise you to arrange a
service contract with your heating con-
tractor.
Operational checks
The following operational checks
should be carried out every month:
Regularly check the pressure of the
system.
Check correct operation of safety
valve.
Check correct operation of control
equipment.
Check all seals and re-seal if
necessary.
Check the ventilation facilities of the
boiler room (see safety note on page
2).
Check function of neutralizing unit.
Check level of neutralizing agent.
Boiler
All boilers have to be cleaned at certain
intervals as the flue gas temperature
and therefore the energy loss rise as
the level of contamination increases.
We recommend the use of a flue gas
sensor.
The efficiency of the system will be
impaired if the flue gas temperature
is excessively high due to contam
ination of the boiler or incorrect
adjustment of the burner. In this case
it may be necessary to clean the
boiler or readjust the burner.
A built-in hours run meter measures
the operating times of the burner.
The longer the operating times, the
lower the standby losses.
Servicing instructions
Cleaning
The equipment can be cleaned with
domestic cleaning agents available
on the market (do not use abrasive
cleaning agents).
Note on disposal of unwanted
equipment
The unit contains an inbuilt,
non-toxic battery.
To safeguard the environment,
please dispose of spent batteries
properly via the appropriate
collection points.
The battery should be removed by
a competent person.
