Section: Prepare the Burner for Start-up

Set Appliance Limit Controls

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

○Move the low-ﬁre hold switch (not shown) to the low ﬁre hold position. This will hold the burner in low ﬁre during initial start-up.

Prepare the Fuel Unit for Air Venting

1.To vent air from one-pipe oil systems, attach a clear hose to the pump bleed port (item p in Figures 9 & 10) on the fuel unit. Provide a container to catch the oil. Loosen the pump bleed port.

2.Vent the air as described in the ‘Start the Burner’ Section.

Professional Service

Required

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 explosion.

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

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

yExperienced with all applicable codes, standards and ordinances.

yResponsible for the correct installation and commission of this equipment.

ySkilled in the adjustment of oil burners using combustion test instruments.

The installation must strictly comply with all applicable codes, authorities having jurisdiction and the latest revision 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.

Do not proceed unless all prior steps in this manual have been completed.

Explosion and Fire Hazard

Failure to follow these instructions could lead to equipment malfunction and result in heavy smoke emission, soot-up, hot gas puff-back, ﬁre and asphyxiation hazards.

yDo 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.

yDo not attempt to re-establish ﬂame with the burner running if the ﬂame becomes extinguished during start-up, venting, or adjustment.

yVapor-Filled Appliance: Allow the unit to cool off and all vapors to dissipate before attempting another start.

yOil-Flooded Appliance: Shut off the electrical power and the oil supply to the burner and then clear all accumulated oil before continuing.

yIf the condition still appears unsafe, contact the Fire Department. Carefully follow their directions.

yKeep a ﬁre extinguisher nearby and ready for use.

Start Burner and Vent Air from Oil Line

Hot Gas Puff-back and

Heavy Smoke Hazard

Failure to bleed the pump properly could result in unstable combustion, hot gas puff-back and heavy smoke.

yDo not allow oil to intermittently spray into a hot combustion chamber while bleeding.

yInstall 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.

yEnsure that all bubbles and froth are purged from the oil supply system before tightening the pump air bleed valve.

1.Move the low-ﬁre hold switch to the low ﬁre hold position (to hold burner in low ﬁre when started).

2.Verify that the air adjusting cam (Figure 17B, item d) has been set to the initial low-ﬁre air setting as described in the ‘Initial Air Settings’ Section.

3.Open the oil shutoff valves in the oil supply line to the burner.

4.Set the thermostat (or operating control) to call for heat.

5.Close the line switch to the burner. The burner motor should start immediately.
