The green pilot light will come “ON.” Water will begin to enter the boiler. When enough water has entered the boiler,
the (amber) “STANDBY” pilot light will come on.
3. Press the “RESET” switch to begin boiler operation. The “STANDBY” pilot light will go o and the boiler will begin
operation.
Normal Boiler Operating Cycle
Water Fill Cycle
On the initial lling of the boiler, the reset switch must be activated to initialize the safety lockout circuit. Once the water in
the boiler has reached the proper level, the level control will stop the ow of water to the boiler. As water is consumed in
the production of steam, the level control will supply additional water to the boiler.
Firing Cycle
The elements are operated by pressure sensing devices. On initial operation, the boiler should reach 14 psi in
approximately 15 minutes. At this point, the operating pressure switch will open, de-energizing the elements. Thereafter
the operating pressure switch will cycle the elements between 9 and 11 psi boiler pressure.
Condensing Drain
A thermostat is located in the drain assembly and is activated by the temperature of steam. The thermostat operates the
cooling solenoid, supplying water to the drain to condense the steam.
Automatic Blowdown Valve
If the unit has an automatic blowdown valve, it is activated when the main power switch is activated. The boiler will be
drained should the main power switch be turned “OFF.”
Safety Lockout Conditions
High Temperature Condition
A high temperature safety device is installed on the boiler. Should the temperature exceed the limit of this device, the
boiler will be shut down and put in a state of lockout. The “TEMPERATURE” pilot light (red), and the “STANDBY” pilot light
(amber), will come on.
High Pressure Condition
A high pressure safety switch is installed on the boiler. Should the pressure exceed the limit of this device, the boiler will
be shut down and put into a state of lockout. The “PRESSURE” pilot light (red), and the “STANDBY” pilot light (amber),
will come on. Should this device fail to operate, the safety relief valve will open.
Low Water Condition
A second low water safety cut o is supplied with the boiler. Should the water level fall below normal operating levels, the
boiler will be shut down and put into a state of lockout. The “LOW WATER” pilot light (red), and the “STANDBY” pilot light
(amber) will come on.

Periodic Maintenance
WARNING
Disconnect the unit from the power supply before cleaning or servicing appliance.
IMPORTANT INSTRUCTIONS
Be sure to ush your boiler water level control daily. Failure to follow this procedure can cause the control to malfunction
resulting in serious boiler damage.
The Boiler Water Level Control installed on your boiler requires periodic maintenance. As boiler water circulates into
the oat chamber, sand, scale and other sediment may be deposited in the oat chamber. While the chamber has been
designed with a large accumulation bowl, it is necessary to ush the sediment from the chamber by blowing down the
control so that the accumulation of sediment does not interfere with the movement of the oat in the control.
Control must be ushed at least once a day.
CAUTION
Protect yourself. When ushing control, hot water and steam will ow out of the drain.
When flushing control, note water level in gauge glass, allow the boiler to fill if necessary, and also to come up to
temperature.
Before flushing control, note that water level in gauge glass is within operating range and the boiler pressure is
at least 6 psi. While the boiler is being operated, open blowdown valve at bottom of control by rotating the handle
counterclockwise about 1/4 turn to fully open the valve.
Opening the blowdown valve also checks the cut-off operation. Float should drop shutting steam off, hot water and
steam will flow out the drain flushing away sediment.
NOTICE
Contact the factory, the factory representative or a local service company to perform maintenance and repairs should
the appliance malfunction. Refer to warranty terms.
