OPERATING, TESTING, SERVICING AND CLEANING INSTRUCTIONS
Start-up Procedure
1. Close the manual blowdown valve.
2. Open cabinet door and turn "ON" power switch.
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.
1. Press the "RESET" switch to begin boiler operation.
The "STANDBY" pilot light will go off and the boiler will begin operation.
Normal Boiler Operating Cycle
Water Fill Cycle
On the initial filling 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 flow 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."
