Burnham FM01FD00B manual Maintenance of LOW Water Cutoff Devices

f.Use a wire or fiber bristle brush of appropriate length and diameter to allow sufficient cleaning of all flue passages. Using long strokes, push the brush the whole way through the boiler and then pull it out. Repeat this process until all surfaces of each of the flue passages have been cleared of all soot and debris.

g.Vacuum all loose debris that has collected in the rear of the combustion chamber and in the turnaround passages into the second flue passes.

h.Use a wire or fiber bristle brush to clean all of the surfaces of the combustion chamber and turnaround passages to the second flue passes.

i.Vacuum all loose debris in the bottom of the combustion chamber and in the turnaround passages to the second flue passes.

j.Remove the flue collector clean-out covers at the rear of the boiler by removing four (4) 5/16” cap screws and washers. Through these clean- out openings, vacuum all loose debris from the bottom of the flue collector.

3.REASSEMBLE BOILER.

a.Reattach the flue collector clean-out covers to the rear of the boiler, verifying that the silicone- coated rope gaskets are still in satisfactory condition. Replace the rope gaskets, if necessary, before reassembly. Tighten the covers snugly into place using original 5/16” hardware. Do not over tighten.

b.Insert the flue baffles into the appropriate flue passes.

c.Inspect the insulation and silicone-coated rope gasket on the inside of the BSD, making sure that everything is in place and undamaged. If the BSD insulation or rope gasket is damaged, replace them.

d.Carefully close the BSD and secure it in place using the original 9/16” hardware. When tightening the bolts, make sure that the BSD is drawn in equally at all four corners. Use an alternating tightening method from corner to corner to pull the door tight equally around the perimeter.

NOTICE

Do not overtighten. The rope gasket will provide sufficient seal when the door is snugged in place.

e.Reinstall the burner to the BSD (if removed) and secure it in place on its support pedestal. Inspect the burner gasket to assure an adequate seal.

Replace it if damaged.

f.Connect the fuel lines.

g.Reattach the BSD cover panels (if provided).

CAUTION

Do not start the burner unless BSD, smokepipe, flue clean-out covers and burner are all secured in place.

C.MAINTENANCE OF LOW WATER CUTOFF DEVICES

NOTICE

Probe and float type low water cutoff devices require annual inspection and maintenance.

1.PROBE TYPE LOW WATER CUTOFF

Although these devices are solid state in their operation, the probe is exposed to possible contamination in the boiler water and subject to fouling. It is important to physically remove the probe from the boiler tapping annually and inspect that probe for accumulation of scale or sediment.

Follow these steps to inspect, clean and /or replace the probe:

a.Turn off electric service to the boiler.

b.Close isolation valves in supply and return near boiler piping.

c.Drain boiler water to a level below the tapping for the probe.

d.Disconnect wiring connections between the low water cutoff control and the probe.

DANGER

Assure that the boiler is at zero pressure before removing the LWCO probe. Do not rely on the pressure gauge to indicate that the boiler is at zero pressure. Open the relief valve to relieve all internal pressure prior to proceeding. Relief valve discharge piping must be piped such that the potential for burns is eliminated.

e.Dismount the low water cutoff control from the probe.

f.Unscrew the probe from the boiler tapping.

g.Inspect that portion of the probe that is exposed to the boiler water for a scale or sediment buildup.

h.Light deposits may be removed by wiping the probe with a damp cloth. Wiping the probe with a cloth soaked in vinegar will remove more tenacious lime deposits. The most stubborn deposits may be removed from the probe by using a diluted amount (3 part of water to 1 part) of phosphoric acid (H2PO4).
