4.6 Technical Data - Ecoflam Modulating Burners (all models - burner reference "H")
NOTE: The air setting is a guide only. The final setting is subject to combustion testing.
When setting the minimum firing rate, a check must be made following the setting of the burner combustion. The
check is made by running the heater on low fire for a minimum of 15 minutes at the full transport air rate and at typical
ambient conditions. During the test, check that the flue gas temperature does not fall below 125° C. Should the flue
gas temperature fall below 100° C, then the low fire gas setting must be increased to a value that will achieve 125° C
flue gas temperature; otherwise condensation may form in the heat exchanger and flue, causing rapid corrosion and
short operational life.
NOTE: For adjustment of head setting, see Ecoflam Instructions.
