Safety controls are designed and installed to provide protection. Do not tamper with, or bypass any safety control. If a safety control is not functioning properly, shut off all main electrical power and fuel supply to the burner and call a qualifi ed service agency immediately. .. .. .. Keep Service Access Covers Securely Installed These covers must be securely in place to prevent electrical shock, damage from external elements, and protect against injury from moving parts. All covers or service access plates must be in place at all times except during maintenance and service. This applies to all controls, panels, enclosures, switches, and guards or any component with a cover as part of its design. .. ..

Appliance has been filled with water (boilers) andcontrols have been operationally checked. . Burner has been installed in accordance with appliancemanufacturer’s instructions (when available). . Also refer to appliance manufacturer’s instructions (when available) for start-up procedures. Initial head position (Reference Figure 8) 0 The indicator plate assembly markings correspond to head position settings. 0 Loosen the fastener (Figure 8, item d) and slide the indicator plate until the number on the indicator plate corresponds to the initial head setting listed in Table 5, for the desired fi ring rate. 0 When the head position has been set, tighten the fastener and the spline nut. Initial air settings (Reference Table 6) Loosen the air band and shutter, and adjust to the approximate firing rate settings given in Table 6. These 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. Follow the procedures described later in this manual for fine-tuning the air settings. Set appliance limit controls Set the appliance limit controls in accordance with the appliance manufacturer’s recommendations. Prepare the fuel unit for air venting To vent air from one-pipe oil systems, attach a clear hose to the pump air bleed valve (figure 10 & 11) on the fuel unit. Provide a container to catch the oil. Loosen the pump air bleed valve. Vent the air as described in the next section under Start the burner.

Start the Burner Explosion and Fire Hazard Failure to follow these instructions could lead to equipment malfunction and result in heavy smokeemission, soot-up, hot gas puff-back, fi re and asphyxiation hazards. • Do not attempt to start the burner when excess oil has accumulated in the appliance, the appliance is full of vapor, or when the combustion chamber is very hot. • Do not attempt to re-establish flame with the burner running if the flame becomes extinguished during start-up, venting, or adjustment. • Vapor-Filled Appliance: Allow the unit to cool off and all vapors to dissipate before attempting another start. • Oil-Flooded Appliance: Shut off the electrical power and the oil supply to the burner and then clear all accumulated oil before continuing. • If the condition still appears unsafe, contact the Fire Department. Carefully follow their directions. • Keep a fire extinguisher nearby and ready for use. Starting the burner and venting air Hot Gas Puff-back and Heavy Smoke Hazard Failure to bleed the pump properly couldresult in unstable combustion, hot gaspuff-back and heavy smoke. • Do not allow oil to intermittently spray into a hot combustion chamber while bleeding. • Install a gauge in the nozzle discharge port tubing or fully open the pump bleed valve to prevent oil spray from accumulating in the combustion chamber when venting air from the fuel pump. • Ensure that all bubbles and froth are purged from the oil supply system before tightening the pump air bleed valve. 16 Section: Start the Burner -Priming the Pump For 7505 Control: screen.
