7) Run the burner until the fuel pump has been purged of air, then tighten the bleeder valve and immediately
shut down the burner.
8) Reinstall the air tube cover and nozzle line.
9) The burner can now be started normally.
WARNING: Omitting steps 2 and 3 will result in a collection of unburned oil in the combustion chamber creating a haz-
ardous situation upon burner startup.
B) TWO LINE (LIFT SYSTEM)
Turn off the main power source to the burner and remove the air tube cover.
Shines a light source on the photocell (now visible where the air tube cover was removed), return power to the burner
and activate the burner. With the light source in place, the burner will operate in prepurge only. When the pump is suffi-
ciently purged, the hydraulic air shutter will open.
Once the burner is purged, turn off the power source and replace the air tube cover.
Return power to the burner. The burner is now ready to operate.
ATTENTION: It is important that the fuel line be completely sealed and free from air leaks or any internal blockages.
WARNING! WHEN THE BYPASS PLUG IS INSTALLED, A TWO-PIPE SYSTEM MUST BE USED OR FAILURE OF
THE PUMP SHAFT WILL OCCUR.

SETTING THE AIR ADJUSTMENT PLATE

A) Regulation of the combustion airflow is made by adjustment of
the manual AIR ADJUSTMENT PLATE (4) after loosening the
FIXING SCREWS (3 & 5). The initial setting of the air adjust-
ment plate should be made according to BURNER ADJUST-
MENT TABLE.
B) The proper number on the manual AIR ADJUSTMENT PLATE
(4) should line up with the SETTING INDICATOR (2) on the fan
housing cover. Once set, the air adjustment plate should be se-
cured in place by tightening FIXING SCREWS (3 & 5).
C) The final position of the air adjustment plate will vary on each in-
stallation. Use instruments to establish the proper setting for
maximum CO and a smoke reading of zero.
