SECTION III - SERVICE

1.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".

2.VENT SYSTEM. Vent system (see Figure 8 for typical installation) 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.

F.Proper vent damper operation - see Section II, para- graph 9.

G.Remove all accumulations of soot with wire brush and vacuum, see Fig. 29. Remove all obstructions. Replace all deteriorated parts and support properly. Seal all joints.

3.CLEANING BOILER FLUES, see Fig. 29.

Flue passageways in the boiler sections should be checked annually for any blockage or accumulation of soot. To obtain access to flueways:

A. Remove vent pipe, damper (if boiler is so equipped), blocked vent switch, and draft hood.

B. Remove sheet metal screws securing Jacket Top Panel, lift panel and rotate about relief valve piping until top of boiler is exposed.

C. Remove bolts securing Canopy to Boiler Sections. Remove Canopy - flueways are now exposed.

D. Models with flue gas baffles only: Remove baffles by lifting out of flueways.

Using flashlight, examine all flue passageways. If passageways are free of soot and obstruction, replace canopy (and flue gas baffles, if applicable), and seal. Reinstall Jacket Top Panel, draft hood, blocked vent switch, damper (if boiler is so equipped), and vent pipe.

If the flue passageways need cleaning, remove burners as described in paragraph 4 below. Using long handle wire or bristle flue brush and vacuum, brush flueways thoroughly from top of boiler as illustrated in Fig. 29. Replace canopy and seal with boiler putty. Reinstall Jacket Top Panel, draft hood, blocked vent switch, damper (if boiler is so equipped), and vent pipe.

NOTICE

4.BURNERS AND FIREBOX SHOULD BE CLEANED ANNUALLY, AND IF NECESSARY ADJUSTED ONCE A YEAR BY A QUALIFIED SERVICE AGENCY.

A. TO REMOVE BURNERS FOR CLEANING, CHANGING ORIFICE PLUGS, OR REPAIRS.
