CHAPTER 5 Starting and Operating
Instructions
5.1 — Preparation for Startup: All Fuels
The instructions in Chapter 5 are all 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 the following paragraphs, refer to the illustrations and the
contents of Chapters 1, 2, and 3. Instructions for adjusting major components are given in Chapter 6 — Chapter 6
should be reviewed prior to firing. The wiring diagram should also be thoroughly reviewed, 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 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 feedwater is available. 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 the escape of steam is noted after the burner is operating.
Be sure the starting instructions are read completely and 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.
