B40 OIL BURNER START-UP
(Refer to Figure 22-1 to identify burner parts)
1. Remove the enclosure panel cover on the water
heater or boiler to expose the control circuit. The
wiring diagram, located on the backside of the
cover, will show the controls used in our circuitry.
2. Visually check that all components are intact and
no damage has occurred during transit.
3. Check all connections in control cabinet. A loose
connection could cause intermittent shutdowns.
4. Check oil supply lines to insure proper practices
have been followed and installation complies with
local codes. Use only a two-pipe system. Check
for adequate burner intake air supply.
NOTE: Do not tamper with or readjust program
dipswitch settings. This will cause the control
to become inoperable. Damage resulting from
tampering will be excluded from coverage
under the warranty of this unit.
5. Remove the flame safeguard control from its
base. Check the connections in control mounting
base; loose connections can cause nuisance
shutdowns. When applicable, check the time card
or programmer, for good connection.
6. With electrodes exposed, check them for the
proper settings as in Figure 22-4 & 7, pages 7 & 8.
Check for any hairline cracks in the insulators.
Should replacement of burner electrodes be
required, certain procedures must be followed. In
all cases, removal of electrodes is accomplished
by loosening the electrode mounting clamps.
Draw electrodes out of the nozzle assembly
through the holes in the pressure plate.
7. Open manual oil valve(s). Make certain check
valves are positioned for the correct oil flow. There
should not be a manual shut-off valve in the return
line from the pump to the tank.
8. Pull the nozzle assembly to check the ignition
electrodes. See Figure 22-3 & 6, pages 7 & 8.
9. Inspect the electrodes for cracked ceramic or
loose retaining studs that hold the wire within the
ceramic. Select the proper pressure plate hole to
place each electrode and insert the electrode
through the hole, retaining stud end first.
10. Tighten the electrode mounting clamp slightly until
electrode ceramics are seated firmly and
completely in the mounting bracket without gaps
between ceramics and mounting bracket at the
bearing faces.
11. Measure and set electrodes according to Figure
22-4 & 7, pages 7 & 8. After gaps and setting are
complete, fully tighten electrode mounting clamp.
Do not overtighten or insulation may crack.
12. Replace nozzle assembly; be sure to connect the
spark rod wires before installing nozzle assembly
fully into blast tube. Check connections on the
ends of the flame and spark rod wires for good
contact. Look for properly stripped wire ends. Be
sure connectors are firmly attached to the ignition
rod ends. Insulating boots can give a false feeling
of proper seating.
DO NOT MOVE
ELECTRODES. Be careful not to bump
electrodes. Check fan wheel for free rotation.
13. Connect a test meter to the control for reading the
flame response signal.
NOTE: Some controls read the flame signal in
micro amps and some in volts DC. The MC120
series control has two terminals marked for
reading volts DC.
14. Be sure tank is filled with water. Once the burner
is reassembled, a gauge to read pressure,
preferably a 300 psi gauge, will be needed to read
oil pressures. Connect gauge to the pressure side
of the oil pump. Connect vacuum gauge to supply
side of oil pump (15”HG maximum allowed).
15. Single stage oil burners. Before turning the unit
on, make sure all valves in the oil supply and
return lines are on. Check the air damper setting
against the setup tag attached to the burner.
Turn the unit on using the rocker switch on the
side of the control cabinet. If the operating
control switches are closed, the burner blower
should come on and prepurge begins.
If nothing happens, check the control to be sure it
is not in the tripped position and reset it by
pushing the flame safeguard reset button. Burner
should prepurge for no more than thirty seconds.
