OPERATING THE BOILER

NOTE: Although each factory packaged unit has been test fired at the factory, each boiler

must be “set up” for the conditions on location. Improper combustion settings may

cause the burner to operate erratically, resulting in boiler shutdowns, lost time, and

unnecessary service expenses.

PRE-START CHECKS AND INFORMATION

A new or relocated boiler should not be put into service until it has been inspected by an authorized

inspector for the jurisdiction or the insurance company, and the required certificates have been

issued.

Whenever a new boiler is placed in service, operating data should be recorded and saved for future

reference. This information is extremely valuable for diagnosing problems if abnormal operation

occurs. Record all operating parameters such as pressures, stack temperatures, oxygen or carbon

dioxide levels, flows, draft, motor amps, damper positions, and interlock set points. A burner start up

and test information sheet has been included at the end of this section for your convenience.

All cover plates, enclosures, and safety devices must be installed at all times except while perform-

ing maintenance and service.

The fuel supply should not be turned on until the combustion chamber has been vented and the pilot

light (if gas ignited) checked for proper operation.

All drain valves including blowdown valves for stream boilers, water column drain valves, gauge glass

drain valves, and gauge cocks, should be closed.

The safety/relief valves should be inspected externally to see that they are free to operate, and that

the discharge piping and drain piping are open to the atmosphere, and free to expand without impos-

ing a load on the safety valve bodies. Make sure the safety valve is piped to a safe location to pre-

vent injury.

The boiler feed pump(s) for steam applications should be checked to ensure that they are ready for

service. Check the data on rating plates of all electrical equipment to be certain the electrical char-

acteristics match those of the electric supply to which they are connected.

Before attempting start-up, carefully study the instructions included in the burner section of this

manual.

It is important to have the proper test equipment in order to adjust the combustion and pilot if

equipped. Those items that may be required include a manometer, micro ammeter, vacuum gauge, 0-

300 PSI pressure gauge, carbon dioxide or oxygen analyzer, carbon monoxide tester, smoke gun, and

stack thermometer.
