“Heat up” cycle is needed for slow heating of the burning chamber and to minimize thermal stress in
ceramic stones.
“Heat up” mode is selected from main menu between “ON”, “OFF” or “AUTO”.

Par 70 Heat up time 20 min Maximum cycle time
Par 71 Heat up power 30...70 kW Depends from burner model
Par 72 Heat up temperature 500 °C Ceramic stone minimum temperature
When “Heat up” is mode is “ON” - burner will leave from “Heat up” cycle after heat up time is exceeded
(stone temp. is not measured)
When “Heat up” is mode is “AUTO” - burner will leave from “Heat up” cycle after heat up time is
exceeded or stone temp. is higher than setpoint (PAR72)
Burning
This is main operation status in burner operation.
Burner can operate on 11 different fixed power levels. There are 6 main power levels, which can be
selected and adjusted. Virtual power levels (between main levels) are for smoother operation – they
can't be adjusted or selected.
For every power level, the primary fan speed is fixed in parameters 1...6 and secondary fan speed in
parameters 31...36. The fan speed for virtual levels is calculated as average from previous and next main
level speed.
