‰Start-up checklist

‰Combustion air supply and venting have been inspected and verified to be free of obstructions and installed in ac- cordance with all applicable codes.

‰Oil nozzle has been selected correctly and securely in- stalled in the nozzle adapter.

‰Fuel unit by-pass plug has not been installed for one- pipe oil system.

‰By-pass plug has been installed for two-pipe oil system.

‰Fuel connection to nozzle line assembly is secure.

‰Dimension Z has been set per this instruction manual.

‰Fuel supply line is correctly installed, the oil tank is suf- ficiently filled, and shut-off valves are open.

‰Burner is securely mounted in appliance, with pressure firing plate and gasket installed for pressurized chamber application.

‰Appliance has been filled with water (boilers) and controls have been operationally checked.

‰Burner has been installed in accordance with appliance manufacturer’s instructions (when available).

‰Also refer to appliance manufacturer’s instructions (when available) for start-up procedures.

‰Z dimension

Should be set per the Set Z Dimension instructions detailed earlier in this manual. The acorn nut (Fig- ure 6, item c) should never be loosened once the Z dimension is initially set.

‰Initial head position (Figure 6)

yThe indicator plate assembly markings correspond to head position settings.

yLoosen the fastener (Figure 6, item d) and slide the indicator plate until the number on the indicator plate corresponds to the initial head setting listed in Table 3, for the desired firing rate.

yWhen the head position has been set, tighten the fastener and the spline nut.

‰Initial air settings (Table 4)

yLoosen the air band and shutter, and adjust to the approximate firing rate settings given in Table 4.

yThese initial settings should be adequate for starting the burner. Once the burner is in operation, the air settings will be adjusted for best performance as discussed later in this manual.

yFollow the procedures described later in this manual for fine-tuning the air settings.

‰Set appliance limit controls

ySet the appliance limit controls in accordance with the appliance manufacturer’s recommendations.

‰Prepare the fuel unit for air venting

yTo vent air from the oil supply line, attach a clear hose to the vent plug on the fuel unit. Provide a container to catch the oil. Loosen the vent plug.

yVent the air as described in the next section under Start the burner.
