Igniting
In ignition cycle the igniter is heated up and fan blows hot air thru pellets in burning chamber.
Hot air ignites pellets. Igniter is working periodically at ignition time to avoid overheating.
Igniter is preheated already in the end of loading cycle. When internal auger has made 10
rotations (full load rotations* - 12) the igniter is turned on for preheating. If the igniter has been
turned on more than 1 minute at loading time, the igniter is turned off.

Pre-burn
The purpose of pre-burn status is to get correct burning and flame after ignition. There is minimum fuel
amount added periodically at pre-burn time. Fans are working with same speed as at ignition.
