WARNING
Risk of injury due to untrained personnel.
Only allow trained and experienced personnel to operate
the product.
Personnel under training must only work on the product
under supervision.
CAUTION
Risk of burns due to hot system components.
Only touch handles and identified parts.
Never touch sight glasses or their retainers.
The sight glasses and retainers are connected directly
to the combustion chamber.
WARNING
There is a risk of deflagration when the combustion
chamber door is opened. Poking around in the firebed
leads to oxygenation, which can produce a flash.
Both can result in severe burns. Never open the
combustion chamber door during operation.
Switch on the system at the programming unit using the
button.
The combustion chamber is automatically filled with fuel.
The controller switches to the “Ignition” operating state.
The ignition fan is started.
The amount of fuel can be set on the programming unit,
via parameters in the “Fuel” sub-area. Manual adjustment
of the fuel amount is carried out via “Fuel supply”, see
page 70.
Ignition monitoring
The ignition is monitored by the controller. After no more
than 45 minutes, the oxygen content in the flue gas must
drop below 15 % for a set period. You can adjust the
required period via the “Delay, O2, heatup” parameter.
If the oxygen content has dropped sufficiently, the boiler
switches to the “Load” operating state. The ignition phase
is completed.
If the oxygen content has not dropped sufficiently, the
fault message “Fault, repeat heat-up” is displayed.
Check the fuel. If necessary, use drier fuel. Also check
the amount of fuel. If necessary increase the amount of
fuel supplied. Acknowledge the fault message.
Switch off the system via the
button.
The controller switches the system off automatically.
