11.1.5 Cleaning the burner assembly

CAUTION
Turn electrical off, then ensure gas has been shut off at the main shut off valve. Next purge all gas in the system
as per code. The burner may be hot, allow enough time to allow the boiler to cool before removing the burner tube.
Upon removal of the burner tube, inspect it for any damage to the woven mesh and ensure no damage has been done
to the tube from heat. If the burner is in good condition, clean the burner assembly by using compressed air only –
between 30 – 70 psi [2-5 bar] with the nozzle positioned a min of 3/8" [10mm] away and towards the face of the burner.
If there is any damage to the mesh or tube, the burner must be replaced. Check the retaining bolts are tight. If the
burner is removed from the front plate ensure burner-retaining screws are tight on re-assembly
Max. 70 PSI air pressure to clean burner
