Power Indicator: (figure 4) Indicates when power is present at the burner.

•

Run Indicator: (figure 4) Indicates that the burner is ready for operation after the initial

pre-heat time of approx. 5 minutes from initial power up.

•

Fuel Pump: (figure 7, 13) pumps fuel from fuel tank to burner.

•

Fuel Filter: (figure 7, 14) filters fuel prior to entering pump.

•

Fuel Regulator: (figure 7, 12) The fuel regulator increases or decreases delivery of fuel

to the burner. When you increase or decrease the fuel to the burner you will notice the

flame length will increase or decrease. Adjust flame to 3/4 length of combustion chamber

(figure 8) by increasing CW or decreasing CCW the fuel regulator located on the left side

of burner (figure 9).

1. 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.

2. Apply power to the heater. Switch heater main power switch to ON position. Burner motor

will start to run but will not attempt to ignite. After allowing the oil pre-heater time to establish

temperature setpoint, approximately 5 minutes, heater will start to establish flame. 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.

3. 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.

4. 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.

5. Combustion air band (figure 4) 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.
