3 STARTING UP A COLD
SYSTEM
After a long period of not being used, you should
take particular note of the following points when
starting up the system:
Where the equipment has cooled down, the
boiler requires a proportionate amount of
time to reach temperature if all heat
consumers are switched on during the
heating up process. Therefore, firstly put only
one small heating circuit into operation and
only switch the other heating circuits on when
the boiler has reached its operating
temperature. The first start-up should only be
carried out by HERZ factory customer service
or persons authorised as such.
