4.2 IGNITER-INJECTOR
The igniter-injector (Kit P/N

) is located on the burner plate at the top of the boiler. In
addition to providing the ignition spark required to light the burner, the igniter-injector also
contains a gas injector tube which connects to the staged ignition assembly. Figure 4-1a
through Figure 4-1c shows the complete burner assembly removed from the boiler and indicates
the location of the igniter-injector flame detector and other related components.
