SECTION V – SERVICE
1.GENERAL – “Inspection should be conducted annually. Service as frequently as specified in paragraphs below.” While service or maintenance is being done, Electrical Power and all Gas Supply to the Boiler must be “off”.
CAUTION
Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Verify proper operation after servicing.
2.VENT SYSTEM – Vent system should be checked annually for:
a.obstructions
b.accumulations of soot
c.deterioration of vent pipe or vent accessories due to condensation or other reasons
d.proper support – no sags, particularly in horizontal runs
e.tightness of joints
Remove all accumulations of soot with wire brush and vacuum. Remove all obstructions. Replace all deteriorated parts and support properly. Seal all joints. See Fig. 61.
3.CLEANING OF FLUES AND BURNERS – Flue passageways in the boiler sections should be checked annually for any blockage or accumulation of soot.
To obtain access to the flue cleanout panels, which are installed on both the front and rear of the boiler, the upper front and upper rear jacket panels must be removed, see Fig. 59. Also remove front vestibule panel. See Fig. 18.
Remove the Front Cleanout Panels first by removing the upper and lower nuts and washers securing these panels to the boiler sections, see Fig. 60.
Fig. 59
REMOVAL OF JACKET FRONT PANEL
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.

ATTACHMENT OF FLUE COVERS
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. 61.
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.
If Burners must be removed, use the following procedure:
a.Mark location on manifold of all burners with pilots.
b.Using a pair of pliers, remove hitch pin clips (shaped like a hairpin) from groove in main burner orifices. SAVE ALL CLIPS.
c.Remove all burners without pilots by lifting front of burner slightly, then pushing burner toward rear of boiler until front of burner clears orifice, then lift rear of burner until head of weld pin on bottom rear of burner clears keyhole slot in base rear panel. Burner is now free and can be lifted out thru opening in base front frame.
