H. REMOVE GUN ASSEMBLY
1. Check nozzle size, head size, gun setting, and
positioning of electrodes. This information is shown
in Figure 25 and Tables 7 and 7A for Beckett burner,
Figure 25A and Table 7B for Carlin EZ-1HP burner.
2. Reinstall gun assembly.
I.
VERIFY OIL BURNER SETTINGS BEFORE
STARTING
1. BURNER AIR BAND AND AIR SHUTTER
SETTINGS, see Tables 7 and 7A for Beckett burner,
Table 7B for Carlin EZ-1HP burner.
2. OPEN ALL OIL LINE VALVES.
3. Attach a plastic hose to fuel pump vent fitting and
provide a container to catch the oil.
4. REMOVE GAUGE PORT PLUG from fuel pump
and install pressure gauge.
J. 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 pre-purge is complete. Pre-purge
prevents burner flame until 10 seconds has elapsed
after initial power is applied to burner. During
pre-purge, the motor and ignitor will operate but the
oil valve will remain closed. Refer to Oil Primary
Control Instructions for more details.
4. For Carlin burner, refer to “Installation and
Operating Instructions for Packaged Heating/
Burner Units, Carlin Elite Oil Burner” (Form
CCT-569A) for instructions for Bleeding the Pump
and Starting the Burner.
K. ADJUST OIL PRESSURE
1. Locate oil pressure adjusting screw and turn screw
until Pressure Gauge reads the correct pump
pressure required for the specific boiler. Refer to
Tables 7 & 7A for Beckett burners or Table 7B for
Carlin burner (set pump pressure to 150 for Carlin
EZ-1HP Burner).
2. DO NOT REMOVE PRESSURE GAUGE until
later.
L.
OTHER ADJUSTMENTS
Beckett Burner
1. ADJUST THE AIR BAND AND/OR AIR
SHUTTER.
a. Adjust air supply by loosening lock screws and
moving the air shutter and if necessary the air
band. Refer to Tables 7 and 7A preliminary
settings.
2. ADJUST DRAFT REGULATOR for a draft of -
.02” (water gauge) over the fire after chimney has
reached operating temperature and while burner is
running.
3. READJUST AIR BANDS on burner for a light
orange colored flame while draft over the fire is
-.02” w.c. Use a smoke test and adjust air for
minimum smoke (not to exceed #1) with a minimum
of excess air. Make final check using suitable
instrumentation to obtain a CO
2
of 11.5 to 12.5%
with draft of -.02” w.c. in fire box. These settings
will assure a safe and efficient operating condition.
If the flame appears stringy instead of a solid flame,
try another nozzle of the same type. Flame should
be solid and compact. After all adjustments have
been made, recheck for a draft of -.02” w.c. over the
fire.
4. TURN “OFF” BURNER and remove pressure
gauge. Install gauge port plug and tighten. Start
burner again.
Carlin Burner
1-4. Refer to “Installation and Operating Instructions
for Packaged Heating/Burner Units, Carlin Elite
Oil Burner” (Form CCT-569A) for instructions for
Bleeding the Pump and Starting the Burner.
5. Turn “off” Burner and remove pressure gauge.
Install gauge port plug and tighten. Start burner
again.
6. CAD Cell Location and Service. The burner is
supplied with a cadmium sulfide flame detector
mounted at the factory, mounted on the bottom of
the transformer. See “Installation and Operating
Instructions for Packaged Heating/Burner Units,
Carlin Elite Oil Burner” (Form CCT-569A). To
service cad cell or to replace the plug in portion,
swing open the transformer. After service is
complete, be sure to fasten down the transformer.
M. FLAME FAILURE
The RSA boiler controls operate the burner
automatically. If for unknown reasons the burner
ceases to fire and the reset button on the primary control
has tripped, the burner has experienced ignition failure.
Before pressing the reset button, call your serviceman
immediately.
WARNING
Do not attempt to start the burner when excess oil
has accumulated, when the unit is full of vapor, or
when the combustion chamber is very hot.
N. CHECK FOR CLEAN CUT OFF OF BURNER
1. AIR IN THE OIL LINE between fuel unit and
