What does a low water cut off do?
A low-water cutoff is a mechanical device (usually a float switch) that is used to turn off the burner or shut off fuel to a boiler to prevent it from running once the water drops below a certain point. If a boiler is “dry-fired” (burned without water in it) it can suffer rupture or catastrophic failure.
What is Loc on water feeder?
safety lockout feature
If LOC appears in the digital counter, this indicates that the safety lockout feature is activated. This feature engages only when the feeder completes two consecutive feed cycles and the low water cut-off does not re-ener- gized the burner. The feeder can be reset by briefly interrupting power to the heating system.
What is a Hartford loop?
Simply speaking, a Hartford Loop is a configuration of interconnected pipes associated with the gravity condensate return line on a steam boiler, and the point at which that condensation is re-introduced back into the boiler. It exists between the header of the boiler and the gravity return.
How often the low water cut off is tested?
The low-water fuel cut-off should be tested on a regular basis, either weekly or monthly. The frequency of testing should be increased when large amounts of makeup water are required.
What controls the firing of a water boiler?
A boiler that is low on water can create steam pressure and explode as a result. What controls the firing of a water boiler? An aquastat that senses the temperature of the water in the boiler.
How should a low water fuel cutoff be tested and at what frequency?
If a low-water condition develops, it could very well result in an overheating and explosion of your boiler. The low-water cutoff should be tested at least weekly. pump and monitor the boiler water-level.
What does LWCO mean?
Boilers can be protected by a simple, inexpensive low-water cutoff (LWCO). An LWCO device actively monitors the water level in the boiler, then cuts power and shuts down the system if the level drops below a safety threshold.
