12. If you want to remove the baffle from the tray, rotate it within the tray before starting to remove it.
Cleaning
1. Refer to the burner removal illustrations on the next page. Remove the burners and sealing
gaskets from their seats. Using compressed air blow them from the convex side to the dished
side.
2. The burner sealing gaskets must be replaced after each burner cleaning. Position the
replacement gaskets above the burners and not between the burners and aluminum boiler
body.
3. Using a water jet, wash the combustion chamber. Use care to avoid wetting the electrical
wiring. During this operation, ensure that the condensate drain pipe is free of blockage so water
does not accumulate in the tray.
4. Using compressed air, blow out the combustion chamber between the sections to remove all
dirt and foreign particles from the aluminum protrusions. Inspect the flue duct and flue collector.
Reassembly
1. Replace the burner sealing gaskets · Reassemble all the components previously removed by
reversing the order of the disassembly steps.
2. Before starting the boiler, verify that the condensate siphon is filled with water.
3. Before opening the gas cock on the burner manifold, make sure that he coupling is securely
tightened. To do this, open the gas cock and check the union for leaks using a soap solution.
4. As soon as a burner is put into operation, check immediately for leakage between the gas valve
and the relevant premixing chamber.
5. Perform the combustion analysis and check the combustion parameters.
Make sure that all the gas pressure test nipples previously opened, are closed and tight.
