BU56: FERROLI - SUN G10 Diesel burner setting guide
This is a guide only, the exact settings required must be determined by running a bacharach
smoke test as the final step in the procedure .
Step1: Select the burner output:
Make an estimation of the output required and match the nozzle size and pump pressure to
achieve the kW output.
Step 2: Fitting the nozzle & positioning the electrodes
After fitting the nozzle, check the correct position of the electrodes and baffle, according to the
distances shown below.
Step 3: Adjust the settings
Adjust the diesel pressure, head setting, & air setting to match the required output as per the
chart below.
Adjust the head adjustment A by regulating the hex bolt B
Adjust the Air adjustment by turning the damper adjuster C
Fit the pressure gauge to the P port on the diesel pump
and set the Diesel pressure by turning screw D
Step 4: Fine tune & Confirm the settings
Run the bacharach smoke tester and adjust the Air adjustment C until a test between 1 & 2
is achieved. If the flue test is too sooty more air is required, if the test is too light less air is
required. A test reading of 0 is an indication of excess air which can cause intermittent starting
problems.
