extent necessary to insure freedom from obstructions and proper functioning of the working parts.
Inspect connecting lines to boiler for accumulation of mud, scale, etc., and clean as required. Examine all
visible wiring for brittle or worn insulation and make sure electrical contacts are clean and that they
function properly. Complete replacement mechanisms, including necessary gaskets and installation
instructions are available from TRIAD. After re-assembly test as required.
7.7.3 Pushbutton Shunt
A LWCO may also have a momentary push button shunt wired in the LWCO circuit that allows continuous
boiler firing while blowing down the water column. When used, a LWCO indicator will still operate. If
continuous firing is desired, the shunt button will need to be manually held until this indicator has
switched off. The pushbutton shunt shall never be tampered with to allow operation without a person
operating the button. This button will be located on the junction box.
7.7.4 LWCO
Water boilers are equipped with a probe type LWCO with a manual reset. In the event this device is
activated to shut off the burner, the operator must reset the device. This ensures the operator is aware
that the LWCO is not operating as designed. If your LWCO is a probe type, the reset button is located on
the boilers junction box located near the water column mounted on the boiler.
7.7.5 Water level manual reset
Probe type water level controls have the reset button located on either on the junction box or on the
probe holder.
7.8 Water level operations
7.8.1 Maintaining Proper Water Level
Operating without sufficient water to cool pressure parts is the most common way to destroy a boiler.
Maintenance of water at a safe level in the boiler is of vital importance. It must not be allowed to go low
enough to endanger the boiler through overheating. Automatic level control devices and low and high
level alarms should be considered solely as operating aids and should not be relied upon entirely. Water
level, as indicated by two or more devices, should be frequently compared. Significant (more than 1/2”)
differences in level indications should be promptly investigated and reconciled.
Other indications of low water conditions include higher than normal water or stack temperature.
Operation of the unit can be maintained provided immediate action is taken to restore the water level to
normal level. This should be done with care, using all indicators available, such as feedwater flow meter,
and all other instruments that properly sense the operating conditions of the boiler.
