[1] Heavy fuel oils require heating to obtain proper viscosity (less than 100 SSU or 21 cs) for optimal atomization. Temperature of HFO should be
measured at burner inlet, not HFO storage tank or oil heater outlet.
(See Application Engineering Data Sheet for OXY-THERM
Burner fuel oil insert and oil piping near the fuel inlet should be purged with compressed air after shut down
to clear any remaining fuel oil. Failure to do so may cause plugging of oil atomizer and nozzle, and cause
poor or improper performance.
