4.3 — General Preparation for Startup: All Fuels
Instructions in this chapter are based upon installation being complete and all electrical, fuel, water, and vent
stack connections are made.
The operator should be familiar with the burner, boiler, and all controls and components. The wiring diagram and
sequence of operation should also have been studied.
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 pro-
grammer and reset if necessary.
The boiler should be filled with water to the proper operating level using water of ambient temperature. Be sure
that feedwater treatment measures appropriate for the installation are being followed. In heating applications,
the entire system should be filled and vented. Refer to the water requirements section of this manual. On a
steam boiler, open the vent valve to vent air displaced during filling. Leave the vent valve open until steam is
noted after the burner is operating.
Check for rotation of all motors by momentarily closing the motor starter or relay. The blower impeller rotation is
counterclockwise when viewed from the front of the boiler. The air pump rotation is clockwise when viewed from
the drive end.
Before operating the boiler feed pump or oil supply pump, be sure all valves in the line are open or properly posi-
tioned.
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.
Inspect the low-water cutoff and pump control as well as the auxiliary low-water cutoff (if so equipped). See
manual 750-281 for complete information on the CB Level Master.
It is recommended that the starting instructions be 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 injury or death.
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 emission of hot water or steam cannot pos-
sibly cause injury. Failure to follow these instructions could result in serious injury or death.
