START OIL BURNER .
1. Open vent fitting on fuel pump.
2. PRESS RED RESET BUTTON on primary
control, hold for ten (10) seconds and release
to reset primary control.
3. 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.
NOTE:
For Primary Control "Pump Priming
Cycle" details, see Paragraph I, No. 2., Step a.,
Item
ii
.
4. Close vent fitting and burner flame should
start immediately after prepurge is completed.
Prepurge prevents burner flame until 15
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.
5. 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. For Beckett burner refer to
Figure 32.
b. Locate oil pressure adjusting screw and
turn screw to obtain proper pump pressure,
refer to Tables 9A, 9B and 10 at the rear of
this manual.
c. To check the cut-off pressure, deadhead
a reliable pressure gauge onto the copper
connector tube attached to the nozzle port.
Run the burner for a short period of time.
Shut the burner off. The pressure should
drop and hold.
d. Turn "OFF" the burner. Remove the
pressure gauge and install port/bleeder
plug and/or reconnect the nozzle port line
and tighten. Start the burner again.
G .
ADJUST OIL BURNER WHILE
OPERATING .
(flame present)
1. ADJUST DRAFT REGULATOR (Natural Draft
only) for a draft of zero inches (water gauge)
in the canopy (see Figure 15) after chimney
has reached operating temperature and while
burner is running. (At least five minutes)
See Tables 9A, 9B and 10 at the rear of this
manual for additional details.
2. READJUST THE AIR DAMPER SETTING
(Air Band/Air Shutter/Air Gate) on burner for
a light orange colored flame while the draft
in the canopy is zero inches water column
("w.c.). Use a smoke tester 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 13.0% with draft of zero inches
water column ("w.c.) (water gauge) in canopy.
These settings will assure a safe and efficient
operating condition. If the flame appears
stringy instead of a solid fire, try another
nozzle of the same type. Flame should be
solid and compact. After all adjustments are
made recheck for a draft of zero inches water
column ("w.c.) in the canopy. Replace plug at
completion.
See Tables 9A, 9B and 10 (at the rear of this
manual) for details regarding the overfire
pressure when baffles are both installed and
removed.
NOTE
: Paragraph G, Step 1
MUST BE
repeated every time the Air Damper Setting is
readjusted.
3. ONLY READJUST THE HEAD /
TURBULATOR SETTING, if necessary.
Beckett AFG Burners
a. EMP84E thru EMP140E:
Beckett MB(L1 & L2) Head burners have a
fixed head which are non-adjustable.
b. EMP182E and EMP224E:
Beckett MD(V1) (variable) Head burners
have the ability to control air by moving the
head. It might be necessary to move the
head forward or back one position at a time
to optimize the smoke and CO
2
readings.
See Figure 28.
