4.3 Switching off the heater
After work has been completed, or when
the heater is no longer required:
- Switch off the On/Off switch (31) in the
switch cabinet.
- Close the quick action valves and both
bottle valves.
m If these valves are not closed, there is a
danger of fire and explosion due to the
possible escape of uncombusted gas!
Always close the valves during breaks
and after work has been completed!

monitoring and separate ON/OFF

switch cabinet; this
- opens the electromagnetic non-re-
turn valves for the gas supply to the
burners;
- activates the electronic ignition sys-
tem, causing the gas to be automat-
ically ignited by the spark plugs and
controlled by the flame monitoring
system.
A
Indicator lamp (2) indicates that the
heater is switched ON.
A malfunction is shown by the indicator
