c.Upon reinstallation of the nozzle line assembly, check that head/air plate setting number pointer lines up with a number on the scale, which matches a value shown in Table 6 for a particular boiler/burner model.
2.Open all
3.Attach a plastic hose to fuel pump vent fitting and provide a container to catch the oil.
4.REMOVE GAUGE PORT PLUG from fuel pump and install pressure gauge.
5.REMOVE TEST PLUG IN FLUE COLLAR.
6.Close the service switch to start the burner. If the burner does not start immediately, check the manual overload switch on the motor, if so equipped, and the safety switch of the burner primary control.
WARNING
Very hot flue gases come out of sight hole when boiler is operated without sight plug installed. Always wear proper eye protection.
7.Bleed the fuel unit when the burner motor starts rotating. To bleed, loosen the vent fitting (with plastic hose attached) and catch the oil in an empty container. Continue to bleed for 15 seconds after oil is free of air bubbles. Tighten the vent fitting when all the air is purged. NOTE: Bleeding might not be necessary with a two pipe system. When vent fitting is closed, burner flame should start immediately.
8.INSTALL PRESSURE GAUGE
a.Either, remove plastic hose and oil pump vent fitting, then, install a reliable pressure gauge into vent fitting port, or install the gauge into the nozzle port. See Figure 20B.
