CL Installation & Service Manual
c. To check the cutoff 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. Remove the gauge and install bleeder port
and/or reconnect the nozzle port line.
G. ADJUST OIL BURNER WHILE OPERATING.
(flame present)
1. SET ROOM THERMOSTAT about 10°F below
room temperature.
2. PRESS RED RESET BUTTON on Oil Primary
Control and release.
3. READJUST THE HEAD SETTING only if
necessary.
4. ADJUST DRAFT REGULATOR for a draft of
-0.02" (water gauge) over the fire after chimney
has reached operating temperature and while
burner is running.
WARNING
DO NOT loosen or remove any oil line fittings
while burner is operating.
5. READJUST THE AIR SETTING on the burner
for a light orange colored flame while the draft
over the fire is -0.02". 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 -0.02" (water
gauge) in fire box. 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 -0.02" over the fire.
6. FLAME FAILURE
The CL 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 XV, Troubleshooting,
Paragraph B. If the failure re-occurs, call your
heating contractor immediately before pressing
the reset button.
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, No. 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.
2. VERIFY OIL PRIMARY CONTROL FEATURES
using procedures outlined in Instructions
furnished with control or burner:
WARNING
Cad Cell Jumper must be removed after this
check.
3. CHECK HIGH LIMIT
a. Adjust system thermostat(s) to highest
setting.
b. Allow burner to run until boiler water
temperature exceeds high limit setting. The
burner should shut down and circulators
continue running.
c. Allow the temperature to drop below control
setting. The burner must restart.
d. Boiler installation is not considered
complete until this check has been made.
