Adjustment mode - gas-fired operation
To enter this adjustment mode, the burner must be on standby.
Standby means that the burner is connected to the power supply, but no heat-
ing request has been issued and the burner is switched to gas-fired operation.
If

the unit is running in standby mode and has already been configured.
