5.3 Boiler operating statuses
Availability of the listed operating statuses depend on the set boiler type!
Preparation The boiler is ventilated, the Lambda probe heated and the ash screws are switched on;
underpressure test.
Heating up The stoker is filled with fuel and a quantity of fuel that can be ignited is pushed onto the grate.
Close BBF The burn back protection system (burn-back flap) closes. (depending on the boiler type).
Pre-heating The fan-assisted ignition switches on and the fuel is pre-warmed until a flame forms. For this
period infeed is deactivated.
Pre-heating – Ignition
Ignition The fan-assisted ignition ignites the fuel. The flame is distributed throughout the entire
combustion chamber. Control of the induced draught fan and infeed for this operating status
are defined in the "Ignition" parameter menu.
Open BBF The burn back protection system (burn-back flap) opens. (depending on the boiler type).
Heating The boiler controller controls combustion according to the boiler setpoints.
Heating - Cleaning The output of the boiler and the infeed unit are reduced and the grate is cleaned. After cleaning
the boiler output is increased again.
Empty stoker The stoker is emptied according to procedure.
Awaiting shutdown Safety time during which the residual material on the grate is burnt.
Fan run-on 1 1. Safety time during which the residual material on the grate is burnt.

this status the stoker is emptied at minimum fuel feed-in (Parameter: “The time until the
stoker is empty is”) whilst the ignition fan is active. The boiler then switches to
“Shutdown wait” status and “Tilt grate”. It will remain in this status for at least 30 mins
