System Start-Up

All boilers equipped with burner swing door have a potential hazard which can cause severe property
damage, personal injury or loss of life if ignored. Before opening swing door, turn off service switch to boiler
to prevent accidental firing of burner outside the combustion chamber. Be sure to tighten swing door fastener
completely when service is completed.
A. ALWAYS INSPECT INSTALLATION BEFORE
STARTING BURNER.
1. Verify that the venting, water piping, oil piping,
and electrical system are installed properly.
Refer to Installation Instructions contained in
this manual.
2. Confirm all electrical, water and oil supplies
are turned off at the source and that the vent is
clear from obstructions.
!
WARNING
Completely read, understand and follow all
instructions in this manual before attempting
start up.
B. FILL HEATING SYSTEM WITH WATER.
NOTICE It is important, especially in a steam
system, to properly remove the oil and dirt from
the system. Failure to clean the system can result
in erratic water lines and surging.
CLEAN HEATING SYSTEM if boiler water or
condensate return water is dirty or if erratic water
lines or surging exist after a few days of boiler
operation.
Refer to Maintenance and Service Instructions
Section of this manual for proper cleaning
instructions for steam boilers.
1. STEAM BOILERS — Fill boiler to normal water
line. Refer to Figure 1-1.
!
is posted on the ASME Data Label located
on the top of the boiler. Never exceed this
pressure. DO NOT plug safety or relief valve.
C. CHECK CONTROLS, WIRING AND BURNER
to be sure that all connections are tight and
burner is rigid, that all electrical connections have
been completed and fuses installed, and that oil
tank is filled and oil lines have been tested.
D. ADJUST CONTROL SETTINGS with burner
service switch turned "ON".
1. SET ROOM THERMOSTAT about 10°F below
room temperature.

WARNING
2. PRESS RED RESET BUTTON on front of
Primary Control, hold button for one (1) second
and release to reset primary control.
3. STEAM BOILERS:
With an L404F Pressure Limit - set cut-out
pressure (MAIN scale) on the pressure limit
for (1) PSI and differential pressure (DIFF.) for
.5 PSI. These pressures may be varied to suit
individual requirements of the system.
4. STEAM BOILERS WITH TANKLESS
DOMESTIC WATER HEATERS, set boiler
water temperature dial on L4006 operating
control at 190°F (max.). Set differential at 10°.
5. CHECKOUT
Put the system into operation and observe
at least one complete cycle to make sure
that the controller operates properly. See
Troubleshooting Section to use LED to assist in
determining system operation.
E. ADJUST OIL BURNER BEFORE STARTING.
1. CHECK BURNER SETTINGS and readjust if
necessary, see Burner Specifications, Table 12
at the rear of this manual.
F. START OIL BURNER.
1. Open vent fitting on fuel pump.
2. TURN 'ON' BURNER service switch and
allow burner to run until oil flows from vent
fitting in a SOLID stream without air bubbles
for approximately 10 seconds.
3. Close vent fitting and burner flame should
start immediately after prepurge is completed.
Prepurge prevents burner flame until 10
seconds has elapsed after initial power is
applied to burner. During prepurge the motor
and igniter will operate but the oil valve will
remain closed. Refer to Oil Primary Control
Instructions for more details.
4. Adjust oil pressure.
a. When checking a fuel unit's operating
pressure, a reliable pressure gauge may
be installed in either the bleeder port or the
nozzle port. Refer to Figure 8-1.
b. Locate oil pressure adjusting screw and
turn screw to obtain proper pump pressure,
refer to Tables 14-1 and 14-2 at the rear of
this manual.
