Check the Insert
Check that the correct insert is installed in the firebox, and that the insert is free from any buildup that
may block air flow. Remove and clean the insert if needed. Below is the correct insert for this operating
mode.
11.3 Firing
General Instructions
It is necessary to configure the firing process so that a full-area fire bed can form. The purpose of
this section is to clarify bulk material heating with the Flex fuel in a visual manner.
In general your bulk material should correspond to the specification described in section 6.2. It is
particularly important that you determine whether sufficient power demand is available prior to
the firing process. First check the temperatures in your buffer tank(s). If the temperature is still suf-
ficient, you should postpone the firing process until later.
