Servicing instructions
Servicing
Servicing of heating systems is
required under current heating system
regulations 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
contractor.
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
thermometer.
The flue gas temperature can be
monitored with the flue gas
temperature sensor which is available
as an accessory. A flue gas
temperature monitoring system will
provide an indication of incorrect
burner adjustment and the degree of
contamination of the boiler.
The efficiency of the system will be
impaired if the flue gas temperature is
excessively high due to contamination
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 (see VDI 2067 for
guide values).
