1. IMPORTANT - Prior to starting the unit, pre-fill the filter and fuel line with oil to assist priming procedure. Oil pump motor turns at low RPM's and would take significant time to complete priming process if not pre-filled. Make sure the oil supply line fittings are air tight. Vacuum leaks are notoriously hard to find. Pressurizing the line with oil in it can help to locate leaks.

2. Proper Draft: Draft Adjustment is accomplished by using the factory supplied gauge. For proper operation, the draft is to set between .02 and .06 on the negative scale. Rarely in the unlikely event the draft is rushing through the heater and out the stack at a higher rate, a barometric damper may be necessary to slow the draft down to appropriate parameters.

3. During the initial power up process the burner is locked out from energizing until the oil has been properly pre-heated to operating thermo setpoint, approx 3 to 5 minute duration. Once the oil has been pre-heated, power is then applied to burner componenets and oil pump.

4. Once the burner is running, temporarily jump the "F" terminals on the Oil Primary. This will allow the burner to run during the pump priming process.

5. Priming the oil pump: Open bleeder valve one turn until all air is expelled. This may need to be done twice to insure all air is removed. IMPORTANT: When fully purged and flame is established remove temporarily jumpers on "F" terminals of the Oil Primary to allow safety features of the unit to operate properly.

7. Adjust air supply of integrated air compressor to 8-12 P.S.I. This is factory preset, however, due to freight handling settings may be compromised.

8. Combustion air band should be open approximately 1/2" or until flame is clear yellow, not orange. Opening the air band too far may cause delayed in starting or even prevent the flame from starting

9. Air Band Adjustment: All models except the 500 series start with the air band preset from the factory 1 inch open. Next, with the burner running and the oil pump primed so oil is delivered to the burner to establish a flame, adjust the RPM’s at the pump motor to create a flame halfway down the main combustion chamber tube. This is established by viewing it through the vision port just above the burner gun assembly. There is one exception only, High Altitude. In the event of high altitude, set the flame with the same initial steps. Thereafter, opening the air band further may be necessary.

10. Inspect flame length through inspection door located above burner gun assembly. End of flame should reach no further than ½ way down combustion tube. To accomplish this flame length, use adjustment knob on opposite side of oil pump. NEVER ATTEMPT TO START HEATER WHEN COMBUSTION CHAMBER IS HOT AND A DELAYED START OCCURS.

Annual Maintenance: Replace nozzle every 3-5 years depending on usage. Will lose efficiency due to erosion. This can be accessed by swinging burner door open.

Due to erosion, adjustment may change.
CAUTION: TURN OFF MAIN ELECTRIC SUPPLY SWITCH BEFORE CHECKING OR ADJUSTING ELECTRODE SETTING.

MONTHLY (Recommended) --- clean stainless strainer in pre-filter periodically and drain off any water accumulation. Every application is different and may vary depending on contamination of oils being used.

Oil Valve: energizes when burner is running and de-energizes when burner is not running eliminating bleed back of oil out of the Pre-heater block.

Igniter Transformer: Supplies high voltage to the electrodes generating electrical arc igniting the oil.

Remove combustion chamber & heat exchanger clean out panels at same side of lift out door panel on heater and vacuum out the accumulated ash & soot.
