GAS-FIRED WATER BOILER SERIES 2 — Boiler Manual

 

Annual startup (continued)

Perform startup and checks

1.Start boiler and perform checks and tests specified on pages 23 through 26 (and Control Supplement).

2.Verify cold fill pressure is correct and that operating pressure does not go too high.

3.Complete the check-out procedure on page 26.

Check flame signal

1.Flame signal (DC volts from low voltage terminal strip terminal 9 to ground) should be at least 4 VDC.

2.A lower flame signal may indicate a fouled ignitor or damaged ignitor insulation. If cleaning the ignitor does not improve, ground wiring is in good condition, and ground continuity is satisfactory, replace the ignitor.

3.See Troubleshooting in the Ultra Control Supplement for other procedures to deal with low flame signal.

Check burner flame

The boiler contains ceramic fiber materials. Use care when handling these materials per instructions on page 29 of this manual. Failure to comply could result in severe personal injury.

1.Inspect flame through observation window using the procedure on page 25.

2.If flame is unsatisfactory at either high fire or low fire, turn off boiler and allow boiler to cool down. Then remove burner and clean it thoroughly using a vacuum cleaner or compressed air. Do not use compressed air to clean burner if performed inside a building.

3.To access burner, remove the heat exchanger cover plate following the procedure on page 33.

4.When replacing burner, ensure gasket is in good condition and correctly positioned. After tightening the three retainer screws, bend up the retainer tabs as shown in Figure 16 to prevent screw rotation.

5.After servicing, replace boiler components. Retest boiler.

Check flue gas temperature

1.Place the control display in Information mode while the boiler is operating at high fire. See Ultra Control Supplement for details.

2.The flue gas temperature (electronic display first digit shows “5”) must not be more than 60°F higher than the return water temperature (display first digit shows “2”).

3.If the flue temperature is higher than this, shut down the boiler, allow to cool, and follow the procedure on pages 33 through 34 to clean the heat exchanger.

Review with owner

1.Review the User’s Information Manual with the owner.

2.Emphasize the need to perform the maintenance schedule specified in the User’s Information Manual (and in this manual as well).

3.Remind the owner of the need to call a licensed contractor should the boiler or system exhibit any unusual behavior.

4.Remind the owner to follow the proper shutdown procedure and to schedule an annual startup at the beginning of the next heating season.
