2.Check float type low water cutoff for proper operation.

a.Turn operating control to call for heat.

b.Before water gets hot, drain to bottom of gauge glass. Boiler should shut off after water level lowers a few inches.

c.Refill boiler to correct waterline. Boiler should come back on.

1.Clean probe type low water cutoff for proper operation.

a.Turn off power to boiler and wait 5 minutes.

b.Drain water to bottom of gauge glass.

c.Turn on power.

d.Set thermostat to call for heat. Red neon lamp on lower water cutoff should light.

e.Wait 5 minutes. Boiler should not fire.

f.Refill boiler to correct water line. Red lamp should go off.

g.Wait 5 minutes. Boiler should fire.

h.Return thermostat to normal setting.
