Remove the Front Cleanout Panels first by removing
the upper and lower nuts and washers securing these
panels to the boiler sections, see Fig. 56.
CARE SHOULD BE EXERCISED IN REMOVING
THE CLEANOUT PLATES FROM THE BOLTS SO
THAT THE INSULATION IS NOT DAMAGED. IF
DAMAGED, ALL EDGES OF THE CLEANOUT
PLATES SHOULD BE SEALED WITH BOILER
PUTTY WHEN REINSTALLED UNTIL
INSULATION CAN BE REPLACED.
Using a flashlight, examine all flue passageways. If
passageways are free of soot and obstructions, it is not
necessary to remove the rear cleanout panels. Remove
the Burner Access Panels at front of base and place
paper or cardboard over burners. With long handle
wire flue brush and vacuum, brush flueways thoroughly
through front and rear cleanout openings – see Fig. 57.
Remove material placed over burners and vacuum the
following with care so as not to disturb base insulation:
floor, top of burners, primary air opening in burners,
and primary air openings in pilot. This will remove any
dust or lint that may have accumulated as well as any
foreign matter that may have been dislodged during the
cleaning of the flues.
