5.4 Heater Startup

Prior to the initial startup of the heater, make sure the power has been on at least 10 minutes

for the nozzle block to heat up. Once the burner is operating, the system should be checked

and necessary adjustments made. It takes some time for fuel to reach the nozzle and push all

the air out of the system.

DO NOT START THE BURNER UNLESS ALL CLEANOUT COVERS

AND THE FLUE PIPE ARE SECURELY IN PLACE.

This section explains how to prime the metering pump and start the heater.

1. Make sure the used oil storage tank has adequate oil, with oil level above the low fuel

cut off float switch. Do NOT fill with new motor oil as it will not burn properly!

2. If power to the heater is off, switch it on. Wait 10 minutes for the oil preheater to heat up.

3. Verify that the primary control is not displaying any errors or lockouts. You may need

to reset the controller by pressing the reset button.

4. Bridge the T1 and T2 terminals of the primary control with an alligator clip or short wire.

5. Once the burner motor starts running, bridge the F1 and F2 terminals of the primary control.

6. Monitor the view port on the side of the heater to confirm the presence of ignition spark

and observe the status of the flame. If no spark is visible in the view port, remove the

F1-F2 bridge and allow the primary control to automatically reset and reattempt light

off, then replace F1-F2 bridge and confirm that continuous spark has now been

established. If continuous spark cannot be established, stop priming by removing both

bridges and turning off the thermostat; troubleshoot the issue to restore ignition spark,

then return to Step 3.

7. If no fuel sprays from the burner nozzle after 10 minutes of priming, call for technical

support to troubleshoot the issue to restore fuel delivery to the system.

8. When priming is achieved, the flame should light right away. Do not continue to spray

fuel into the chamber if it is not burning!

9. Remove the T1-T2 and F1-F2 bridges to return the unit to normal operation.

Continue to the next section for important checks and adjustments.

10. If the heater will not light, call for technical support.
