OPERATIONS & MAINTENANCE

WARNING

Do not store or allow combustible or flammable materials near the boiler. Substantial fire or explosion hazard could result, causing risk of personal injury, death or property damage.

Do not use this boiler if any part of it has been under water. Immediately call a qualified service technician to inspect the boiler. Any part of the control system, any gas control or any burner or gas component which has been under water must be replaced.

Should overheating occur or the fuel supply fail to shut off: Shut off the fuel supply at a location external to the boiler. Do not turn off or disconnect the electrical supply to the pump. Immediately call a qualified service technician to inspect the boiler for damage and defective components.

A.PLACING BOILER IN OPERATION

1.Start up the boiler per the Lighting Instructions shipped with the boiler.

2.Prove the correct operation of all controls on the boiler as outlined below.

3.Check the operation of the ignition and flame proving controls:

a.Electronic Spark-Ignited Pilot System (S8610M Control)

With the boiler operating, close the Pilot manual shut-off valve.

The ignition control should close the main gas valves within 1 second.

The control will spark and attempt to relight the pilot burner.

After 15 seconds, the control will shut down and wait 5 to 6 minutes for another ignition trial.

Figure 12.1: Pilot and Burner Flames

Open the Pilot manual shut-off valve and re- start the boiler per the Lighting Instructions. (Standing pilots will have to be manually re- lit per the Lighting Instructions.)

b.Electronic Standing Pilot System

With the boiler operating, close the Pilot manual shut-off valve.

The ignition control should close the main gas valves within 3 seconds after the pilot goes out.

After 15 seconds, the control will lock out.

Open the Pilot manual gas shut-off valve and re-start the boiler per the Lighting Instructions. (Standing pilots will have to be manually re-lit per the Lighting Instructions.)

4.Check the manifold gas pressure and use a soap suds mixture to check the gas tightness of all gas joints.

5.Test the limit and operating controls to assure they are operating correctly.

6.Inspect and test all low water cut-offs. (Float type controls must be flushed (blown down) weekly to remove any sediment from the float chamber.)

7.Test the pop safety relief valve(s) using the procedure given by the valve manufacturer on the valve tag.

8.Visually inspect the burner and pilot flames.

a.See Figure 12.1.

b.The flame inner cone should be about 1-1/2" (4 cm) high and should have a very sharp, blue color characteristic.

c.Poor flame conditions can be caused by dirty burners, obstructed orifices, or incorrect gas pressure.
