Trained Service Technician’s Regular Maintenance

•Set Combustion with Test Instruments

1.Allow the burner to run for approximately 5 to 10 minutes.

2.Set the stack or over-fire draft to the level speci- fied by the appliance manufacturer.

•Natural Draft Applications; typically over-fire draft is -0.01” or -0.02” w.c.

•Direct Venting; typically may not require draft adjustment.

•High Efficiency/Positive Pressure Appliances; also vary from traditional appliances (see manu- facturer’s recommendations).

3.Follow these five steps to properly adjust the burner:

Step 1: Adjust the head/air until a trace of smoke is achieved. This can be accomplished by turn- ing the screw on the head/air adjustment plate assembly to increase air (CCW) or decrease air (CW).

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 the CO2 by 1.5 to 2 percentage points. (O2 will be increased by approximately 2.0 to 2.7 percentage points.) Ex- ample: Reduce CO2 from 13.5% to 11.5% (2.6% to 5.3% O2).

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 changed, recheck the smoke and CO2 levels and readjust burner, if necessary.

Step 5: Once the combustion has been set, tighten the lower acorn nut and splined nut on the air ad- justment assembly. See Figure 5.

4.Chimney Vent Systems: Install the burner cover and repeat Steps 2 and 4 above. If CO2 increas- es (O2 decreases), remove the cover and adjust the air setting so the CO2 (O2) with the cover installed meets the requirements of Step 3.

5.Direct Vent Systems with outside air ducted to burner: Install the burner cover.

6.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 manufactur- er’s specifications.

•Cover Installation

1.Install the four cover mounting thumb screws in the cover mounting plate.

2.Install the cover over the mounting plate while aligning the side slots with the installed cover

mounting screws. Page 10

!WARNING ProfessionalRequired Service

Incorrect installation, adjustment, and use of this burner could result in severe personal injury, death, or substantial property damage from

fire, carbon monoxide poisoning, soot or explo- sion.

Please read and understand the manual supplied with this equipment. This equipment must be installed, adjust- ed and put into operation only by a qualified individual or service agency that is:

•Licensed or certified to install and provide technical service to oil heating systems.

•Experienced with all applicable codes, standards and ordinances.

•Responsible for the correct installation and commis- sion of this equipment.

•Skilled in the adjustment of oil burners using combus- tion test instruments.

The installation must strictly comply with all applicable codes, authorities having jurisdiction and the latest revi- sion of the National Fire Protection Association Standard for the installation of Oil-burning Equipment, NFPA 31 (or CSA B139 and B140 in Canada).

Regulation by these authorities take precedence over the general instructions provided in this installation manual.

The following guidelines are provided for routine maintenance.

ˆReplace the oil supply line filter. The line filter car- tridge must be replaced to avoid contamination of the fuel pump and nozzle.

ˆInspect the oil supply system. All fittings should be tight and leak-free. The supply lines should be free of water, sludge and other restrictions.

ˆRemove and clean the pump strainer if applica- ble.

ˆReplace the used nozzle with a new nozzle that conforms to the appliance manufacturer’s speci- fications.

ˆClean and inspect the electrodes for damage, re- placing any that are cracked or chipped.

ˆCheck electrode tip settings. Replace electrodes if tips are rounded.

ˆInspect the igniter spring contacts.

ˆClean the cad cell lens surface, if necessary.
