CHAPTER 4 Starting and Operating
Instructions
4.1 — General Preparation for Startup: All Fuels
Instructions in this chapter assume that installation is complete and that all electrical, fuel, water, and vent stack
connections have been made.
The operator should be familiar with the burner, boiler, and all controls and components. Adjustment of the major
components are given in Chapter 5 and should be reviewed prior to firing. The wiring diagram should also have
been studied, along with the sequence in Chapter 3.
It is recommended that these 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.
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 program-
mer and reset if necessary.
The boiler should be filled with water to the proper operating level using water of ambient temperature. Make sure
that treated feedwater is available and used. In heating applications, the entire system should be filled and vented.
Refer to Chapter 2 for water requirements. On a steam boiler, open the test valve to vent air displaced during fill-
ing. Leave the test valve open until escape of steam is noted after burner is operating.
Check all linkage for full and free movement of the damper and metering valves and cams. This can be done by
loosening the linkage at the damper motor connecting arm and manipulating linkage by hand.
Check for rotation of all motors by momentarily closing the motor starter or relay. Blower impeller rotation is coun-
terclockwise when viewed from front of boiler. Air pump rotation is clockwise when viewed from its drive end.
Prior to firing a boiler, make sure that discharge piing 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 possi-
bly cause injury to personnel or damage to equipment.
