7.3 Burner setting
If changes have been made to the power settings of the burner or
if it has been converted to a different type of gas, this must be
logged in the operating manual and entered on the settings type
plate (fig. 7-4).
The changeover must be provided with the date of implemen-
tation and the signature of the installer.
A locking malfunction can only be reset manually on the
controller of the GCU compact (see chap. 10.4).
With a temporary fault shutdown the burner is switched
off for at least 60 secs.
When the above conditions are back in the normal
working range, a burner release is carried out automatically.
The cause of the last fault is saved in the device and
can be reconstructed, even after power failure, on
restarting the device.
If more than 5 malfunctions are reset within a 15 minute
period the fault code E96 is displayed. Another release
in then only possible after 15 mins.
DANGER OF EXPLOSION!
Escaping gas is a direct threat to human health and safety. Even
a few sparks can cause major explosions.
● Before working on gas carrying parts, always close the
house gas stop valve.
● If you can smell gas, air the room thoroughly. Prevent spark
and flame formation (e.g. from open flames, electric
switches or mobile phones).
● Only heating specialists authorised and trained by the gas or
power supply company should be allowed to work on gas-
conducting parts.
CAUTION!
An improperly adjusted gas burner can lead to a prohibited level
of pollutant emissions, heavy contamination and increased gas
consumption.
● Burner setting should be carried out only by authorised and
recognised heating engineers.
