CHAPTER 5 Starting and Operating
Instructions
5.1 — 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. To quickly locate and
identify the various controls and components mentioned in this chapter, refer to the illustrations and the contents
of Chapters 1, 2, and 3. Instructions for adjusting major components are given in Chapter 6, and these instruc-
tions should be reviewed prior to firing. The wiring diagram should also have been studied, along with the firing
sequence outlined in Chapter 4.
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. Be sure
that treated feedwater is available and used. In heating applications, the entire system should be filled and
vented. Refer to Chapter 3 for water requirements. On a steam boiler, open the test valve to vent air displaced
during filling. Leave the test valve open until steam is noted after the burner is operating.
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.
