Before starting the boiler, the operator should be familiar with the burner, boiler, and all controls and components. To quickly locate and identify the various controls and components mentioned in the following paragraphs, refer to the ‘‘Cleaver-Brooks Operation, Service and Parts Manual’’. Instructions for adjusting major components should be reviewed prior to firing. The wiring diagram should also have been studied, along with the firing sequence.
WARNING!
Be sure the starting instructions are read completely until they are thoroughly understood, before attempting to operate the boiler, rather than performing each operation as it is read for the first time. Failure to follow these instructions could result in serious personal injury or death!
Verify supply of fuel and proper voltage. Check for blown fuses, open circuit breakers, dropped out overloads, etc. Check reset of all starters and controls having manual reset features. Check the lockout switch on the programmer and reset if necessary.
The boiler should be filled with water to the proper operating level using water of ambient temperature. Be sure that treated feed-water is available and used. In heating applications, the entire system should be filled and vented. On a steam boiler, open the test valve to vent air displaced during filling. Leave the test valve open until the escape of steam is noted after the burner is operating.
WARNING!
Prior to firing a boiler, be sure that discharge piping from safety valves or relief valves, and discharge piping from all blowdown and drain valves, is piped to a SAFE point of discharge, so that discharge of hot water or steam cannot possibly cause injury. Failure to follow these instructions could result in serious personal injury or death.
Check all linkage for full and free movement of the damper and metering valves and cams. The check can be done by loosening the linkage at the damper motor connecting arm and manipulating the linkage by hand.
Check for rotation of all motors by momentarily closing the motor starter or relay. The blower impeller rotation is counter-clockwise for the CB-LE, when viewed from the front of the boiler. The air pump rotation is clockwise when viewed from its drive end.
Before operating the boiler feed pump or oil supply pump, ensure all valves in the line are open or properly positioned. For safety reasons, perform a final pre-startup inspection, especially checking for any loose or incomplete piping or wiring or any other situations that might present a hazard. Prior to firing a boiler, be sure that discharge piping from safety valves or relief valves, and discharge piping from all blowdown and drain valves, is piped to a SAFE point of discharge, so that discharge of hot water or steam cannot possibly cause injury. Failure to follow these instructions could result in serious personal injury or death.
