Turning the furnace on and the state function
The furnace is turned on by long pressing P2 for 3 seconds. After that come the next function states of the furnace:
Check Up
During the check up phase the initial checks of the input signals or the probity of safety probes and pressure switches of
the furnace are done. In this phase the flue gas engine runs at maximum speed while the auger and igniter are turned off. The
check up phase lasts for a few seconds, and a successful check up is followed by the ignition phase.
Ignition
The ignition phase consists of four sub phases which alternate, and those are:
-
Preheating
phase
- Pellet preload phase
- Fixed ignition phase
- Variable ignition phase
The message IGNITION is displayed during the entire ignition phase. There are no special markings on the display for sub
phases.
4.5.2.1 Ignition Preheating
At this stage there is warming of the igniter before dispensing of the pellets starts. In order for pellet burning to be as
efficient as possible, it is desirable that the igniter is already preheated at the time when dispensing the pellets starts. At this
stage the igniter is active and the auger is inactive. Flue gas engine runs on lower rpm in order to promote heating of the
igniter.
4.5.2.2 Ignition Preload
In this phase there is the initial dispensing of pellets or the auger loads a certain amount of pellets necessary for ignition.
In this phase the igniter, auger and flue gas engine are active.
4.5.2.3 Ignition – Fixed Phase
This phase is a fixed time period that lasts for 180 seconds and in case that the furnace ignition requirement is reached
before the expiry of this phase it will always last until the end and only after the expiration of the fixed time period will the
furnace move into stabilization phase. In this phase the igniter, auger and flue gas engine are active.
4.5.2.4 Ignition – Variable Phase
