4.0 OPERATION INSTRUCTION FOR BOILERS WITH CSD-1 CONTROLS
(Continued)
Daily Startup Procedure
1. Close the manual blowdown valve, if so equipped.
2. Examine that the pilot burner flame is burning. If the pilot burner is out, a five (5)
minute period of complete gas supply shut off is required before relighting.
3. Open cabinet door and turn "ON" the 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.
4. Press the "RESET" switch to begin the boiler operation. The "STANDBY" pilot light
will go off and the boiler will begin operation.
Daily Shutdown Procedure
1. Turn "OFF" the power switch. Observe that the burners go off.
2. Open the manual blowdown valve, if so equipped. If the appliance is equipped with
an automatic blowdown solenoid valve, the boiler's contents, water and steam will
be blown out and exhausted through the appliance drain. The cold water solenoid
valve will be activated.
Complete Shutdown Procedure
If the appliance is not intended to be operational for a lengthy period, then shut it down
completely.
1. Open the manual blowdown valve, if so equipped.
2. Shut off all supplies of power, gas and water to the appliance.
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 open the circuit to the fill solenoid valve, stopping the flow of water to the
boiler. As the water is consumed in the production of steam, the level control will close
the circuit to the fill solenoid and water will be supplied to the boiler.
