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 12.5% 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 Table 9 (at the end 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. FORCEOL084 through FORCEOL147
Beckett MB(L1 & L2) Head burners have a fixed
head which are non-adjustable.
b. FORCEOL189:
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 33.
Beckett NX Burners
Move the Head/Air Setting forward or back one
position at a time to optimize the smoke and CO
2
readings. See Figure 36.
NOTE : Step outlined in Paragraph g, Steps 1 and 2
above MUST BE repeated every time the Head/
Turbulator or air Damper Setting is readjusted.
WARNING
DO NOT loosen or remove any oil line fittings
while burner is operating.
4. FLAME FAILURE
The FORCEOL 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. Refer to Oil Primary Control
features, Paragraph I, Step 2 of this section and
Section XIV, Troubleshooting, Paragraph B. If
the failure re-occurs, call your heating contractor
immediately before pressing the reset button.
WARNING
DO NOT attempt to start the burner when excess
oil has accumulated, when the boiler is full of
vapor, or when the combustion chamber is very
hot.
5. 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 electronic ignitor. See Figure 38. To
service cad cell or to replace the plug in portion,
swing open the ignitor. After service is complete, be
sure to fasten down the ignitor.
H. CHECK FOR CLEAN CUT OFF OF
BURNER.
1. AIR IN THE OIL LINE between fuel unit and
nozzle will compress when burner is on and will
expand when burner stops, causing oil to squirt from
nozzle at low pressure as burner slows down and
causing nozzle to drip after burner stops. Usually
cycling the burner operation about 5 to 10 times will
rid oil line of this air.
2. IF NOZZLE CONTINUES TO DRIP, repeat
Paragraph H, Step 1 above. If this does not stop the
dripping, remove cut-off valve and seat, and wipe
both with a clean cloth until clean, then replace
and readjust oil pressure. If dripping or after burn
persist replace fuel pump.
I. TEST CONTROLS.
1. Check thermostat operation. Raise and lower
thermostat setting as required to start and stop
burner.
WARNING
Before installation of the boiler is considered
complete, the operation of all boiler controls must
be checked, particularly the primary control and
high limit control.
