An adequate CH load must be present to dissipate the heat generated while the burner is manually
fired. If an adequate CH load is not available, an indirect water heater can be used to dissipate the heat
by creating a domestic hot water call which will enable the DHW circulator.
General remark
To ensure the operation of
the heating system, make
sure to switch on one of the
pumps.
