Resumen del manual
Disconnect power before servicing. Text Box: Electrical shock hazard. Disconnect power before servicing. Text Box: SK9437 Text Box: SK9359 Text Box: DANGER Startup burner/set combustion Do not attempt to start the burner when excess fuel or vapor has accumulated in the appliance. Starting the burner under these conditions could result in a puffback of hot combustion gases, high smoke levels, or otherwise hazardous operation. 1. Open the shutoff valves in the oil supply line to the burner. 2. Open the air dial. This is an initial air setting for the pump bleeding procedure only. Additional adjustments must be made with instruments. 3. Set the thermostat substantially above room temperature. 4. Close the line voltage switch to start the burner. If the burner does not start immediately you may have to reset the safety switch of the burner primary control. 5. Bleed air from the fuel unit as soon as burner motor starts rotating. To bleed the fuel unit, attach a clear plastic hose over the vent fitting. Loosen the fitting and catch the oil in an empty container. Tighten the fitting when all air has been purged from the oil supply system. • If the burner locks out on safety during bleeding, reset the safety switch and complete the bleeding procedure. Note — Electronic safety switches can be reset immediately; others may require a three- to five-minute wait. • If burner stops after flame is established, additional bleeding is probably required. Repeat the bleeding procedure until the pump is primed and a flame is established when the vent fitting is closed. • For R7184 primary controls, see Technician’s Quick Reference Guide, part number 61351 or 61465, for special pump priming sequence. • Prepare for combustion tests by drilling a ." sampling hole in the flue pipe between the appliance and the barometric draft regulator. 6. Initial air adjustment — Using a smoke tester, adjust the air dial (and change firing pin on HLX ATC’s, if necessary) to obtain a clean flame. Now the additional combustion tests with instruments can be made. Set combustion with instruments The combustion must be adjusted using test instruments. Failure to do so could result in burner or appliance failure, causing potential severe personal injury, death or substantial property damage. 1. Let burner run for approximately 5 to 10 minutes. 2. Set the over-fire or stack draft to level specified by appliance manufacturer (usually –0.01 to –0.02 inches w.c. over-fire for natural draft applications). 3. Follow these four steps to properly adjust the burner: Step 1: Adjust air until a trace smoke level is achieved Step 2: At the trace of smoke level, measure the CO2 (or O2). This is the vital reference point for further adjustments. • Example: 13.5% CO2 (2.6% O2) Step 3: Increase the air to reduce CO2 by 1 to 2 percentage points. (O2 will be increased by approximately 1.4 to 2.7 percentage points.) • Example: Reduce CO2 from 13.5% to 11.5%. (O2 – 2.6% to 5.3%) Step 4: Recheck smoke level. It should be zero. • This procedure provides a margin of reserve air to accommodate variable conditions. • If the draft level has to be changed, recheck the smoke and CO2 levels. Adjust the burner air if necessary. 4. Once combustion is set, tighten all fasteners on air dial, rear access door and escutcheon plate. 5. Start and stop the burner several times to ensure satisfactory operation. Test the primary control and all other appliance safety controls to verify that they function according to the manufacturer’s specifications. Perform regular maintenance This equipment must be serviced only by a qualified service agency. The appropriate test instruments must be used. Failure to do so could result in burner or appliance failure, causing potential severe personal injury, death or substantial property damage. .. Replace the oil supply line filter. The line filter cartridge must be replaced to avoid contamination of the fuel unit and nozzle. .. Inspect the oil supply system. All fittings should be leak-tight. The supply lines should be free of water, sludge and other restrictions. .. Remove and clean the pump strainer if applicable. .. Replace the nozzle with an equivalent nozzle. .. Clean and inspect the electrodes for damage, replacing any that are cracked or chipped. .. Check electrode tip settings. Replace electrodes if tips are rounded. .. Inspect the igniter cables and connections. .. Clean the cad cell grid surface, if necessary. .. Make sure the burner housing baffle is in place if required for the burner application (AFII 85 & AFII 100). Omitting the baffle can result in unacceptable burner combustion. .. Inspect all gaskets. Replace any that are damaged or would fail to seal adequately. .. Clean the blower wheel, air inlet, air guide, and retention head of any lint or foreign material. .. If motor is not permanently lubricated, oil motor with a few drops of SAE 20 nondetergent oil at each oil hole. DO NOT over oil motor. Excessive oiling can cause motor failur...
