Control methodology
ImmersoJet burners use a modulating on-ratio control system
as shown in Figure 3.3. To control the heat delivered by the
burner, adjust the air flow to the burner. The gas flow will
change in proportion to the air flow.
The burner will operate reliably at any input between the low
fire and high fire limits stated on the burner‘s Data Sheet.
