IV. Service

1GENERAL — 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.

2VENT SYSTEM — Vent system (see Figure 4 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 attachment of vent cap and sealant around wall penetration

e.Remove vent cap and clean accumulations of soot and dirt with wire brush and vacuum. See Figure 16. Remove any obstructions. Replace all deteriorated parts.

3CLEANING BOILER FLUES (See Figure 16).

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

a.Remove jacket front panel.

b.Remove sheet metal screws securing combustion area enclosure cover and remove cover. Exercise care when removing to prevent damage to enclosure gasket.

c.Remove fan assembly after disconnecting electrical leads and vent tube. Care should be exercised to avoid damage to gaskets.

d.Remove four (4) bolts securing canopy and remove canopy — flueways are now exposed.

Using a flashlight, examine all flue passageways. If passageways are free of soot and obstruction, replace canopy, secure and seal using kit available from Burnham distributors.

e.Replace fan, connect vent tube and electrical wiring.

f.Reinstall and secure enclosure cover and jacket front panel.

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 boilers as illustrated in Figure 16. Replace canopy and seal.

4BURNERS AND FIREBOX SHOULD BE CLEANED ANNUALLY

a.Remove jacket front panel.

b.Remove sheet metal screws securing enclosure cover and remove cover exercising care with gasket.

c.Remove TCO leads from TCO and remove burner access panel.

d.Brush top of burner with a soft bristle brush and vacuum burner, see Figure 16. Check orifice to see that drilled passageway is free of lint and dirt.

e.Vacuum tips of pilot burner.

f.Clean firebox by vacuuming. Exercise care not to disturb insulation inside base.

5REMOVAL OF BURNER ASSEMBLY

a.Disconnect pilot tubing coupling, ignition cable and ground wire from pilot assembly.

b.Disconnect gas valve at union between valve and bulkhead penetration.

c.Remove two fasteners attaching burner to bulkhead and single fastener for burner end support.

d.Grasp burner, tilt upward and remove from unit.

e.INSTALL BURNER by reversing procedure used to remove.

6REMOVAL OR REPLACEMENT OF PILOT ASSEMBLY OR PILOT ASSEMBLY PARTS

a.If pilot assembly, sensor or pilot orifice need replacement, remove jacket front panel, enclosure cover and burner access panel using procedure described in paragraph 4 above.

b.Disconnect pilot tubing, ground wire and ignition sensor cable.

c.Remove two machine screws holding pilot burner to pilot bracket.

d.Reinstall pilot burner by reversing above procedure.

e.Check pilot and main burner flames, refer to Figures 14 & 15.

7CHECK MAIN BURNER AND PILOT FLAMES, refer to Section III, paragraphs 6 and 10.

8CHECK ALL CONTROLS ANNUALLY, see procedure in Section III, paragraphs 7, 8, 9, 11 and 12.

MAINTENANCE OF LOW WATER CUTOFF

— During the heating season, if an external float type low water cutoff is on the boiler, the blow off valve should be opened once a month (use greater frequency
