Pre-installation checklist
❏ Combustion air supply
• The burner requires combustion air and ventilation air for
reliable operation. Assure that the building and/or combustion air openings comply with National Fire Protection
Standard for Oil-Burning Equipment, NFPA 31. For appliance/burner units in confined spaces, the room must have
an air opening near the top of the room plus one near the
floor, each with a free area at least one square inch per
1,000 Btu/hr input of all fuel burning equipment in the
room. For other conditions, refer to NFPA 31 (CSA B139M91 in Canada).
• If there is a risk of the space being under negative pressure
or of exhaust fans or other devices depleting available air
for combustion and ventilation, the appliance/burner
should be installed in an isolated room provided with outside combustion air.
❏ Clearances
• With the burner installed in the appliance, there must be
adequate space in front of and on the sides of the burner to
allow access and operation. Verify that the clearance dimensions comply with all local codes and with the appliance manufacturer's recommendations.
❏ Fuel supply
• The fuel supply piping and tank must provide #1 or #2
fuel oil at pressure or vacuum conditions suitable for the
fuel unit (oil pump) on the burner. Refer to fuel unit literature in the literature envelope in the burner carton to verify
allowable suction pressure.
❏ Vent system
• The flue gas venting system must be in good condition
and must comply with all applicable codes.
❏ Electrical supply
• Verify that the power connections available are correct for
the burner. All power must be supplied through fused disconnect switches.
❏ Verify burner components —
• Burner box, Model CF500 and CF800
• Air tube assembly (selected per following)
• Mounting flange kit
• Pedestal mounting assembly kit (recommended)
• Oil nozzle, per Table 1 — Use only 45° to 70° solid pat-
tern nozzles unless otherwise shown by appliance manufacturer.
Find the required firing rate in the 150 psig column (factory-set fuel unit pressure).
Select the corresponding nozzle from column 1 (Rated
gph @ 100 psig).
Table 1 - Nozzle capacities
The fuel unit is shipped without the by-pass
plug installed for CF500/CF800 ON/OFF
burners. You must install this plug on twopipe systems. DO NOT install the by-pass plug
in the fuel unit if connected to a one-pipe oil
If fuel supply is level with or higher than fuel unit —
• When the fuel unit is not required to lift the oil, the installation is usually suitable for either a one-pipe or two-pipe
oil system. The oil pressure at the inlet of the fuel unit must
not exceed 3 psig.
• See Figure 7 for one-pipe fuel supply installations. See
Figure 8 for two-pipe fuel supply installations.
If fuel supply is below the fuel unit —
• Use a two-pipe oil system when the fuel unit must lift the
oil more than 8 feet if burner is equipped with a B fuel unit.
The return line provided by the two-pipe system is needed
to purge the air from the fuel lines and minimize the
likelihood of air-related problems during operation.
system. Failure to comply could cause fuel
unit seal failure, oil leakage and potential fire
and injury hazard.

❏ Verify firing rate
• Refer to appliance manufacturer’s instructions (if available) for firing rate and nozzle selection. Otherwise, the
maximum recommended firing rate for the burner depends
on the length of the firing chamber and the distance from
the burner center to the chamber floor. Verify that the chamber dimensions are at least as large as the minimum values
given in Figure 1. If the appliance dimensions are smaller
than recommended, reduce the firing rate accordingly.
❏ Verify air tube
• The information in this section may be disregarded if the
air tube is supplied by the appliance manufacturer.

Connect fuel line(s)
Install the oil lines using the following
guidelines. Failure to comply could lead to
equipment damage and present a risk of severe
personal injury, death or substantial property
damage due to leakage of oil and potential
fire hazard.
Use only flare fittings at joints and
connections. Never use compression fittings.
Install fittings only in accessible locations to
assure any leak will be detected.
Where joint sealing is needed, use only pipe
dope. Never use Teflon tape. Tape strands can
break free and damage the fuel unit.
Never use a one-pipe oil system with a lift in
excess of 8 feet with
oil systems, verify that the suction line
vacuum does not exceed the fuel unit
manufacturer’s recommendation.
The fuel unit is shipped without the by-pass
plug installed for CF500/CF800 ON/OFF
burners. You must install this plug on twopipe systems. DO NOT install the by-pass plug
in the fuel unit if connected to a one-pipe oil
system. Failure to comply could cause fuel
unit seal failure, oil leakage and potential fire
and injury hazard.
B fuel unit. On two-pipe
❏ Fuel unit by-pass plug
• The CF500/CF800 burner is shipped without the by-pass
plug installed in the fuel unit.
• The by-pass plug must not be installed in the fuel unit for
one-pipe oil systems.
• You must install the by-pass plug if using on a two-pipe
oil system.
❏ Oil supply/return lines
• Install the oil tank and oil lines in accordance with all
applicable codes.
• Size the oil supply and return lines using the guidelines
given in the fuel unit literature included in the literature
envelope. Oil line flow rate will equal the burner rate for
one-pipe systems. For two-pipe systems, refer to Table 3
for the fuel unit gearset capacity - the rate at which fuel is
recirculated when connected to a two-pipe system. Size
two-pipe oil lines based on this flow rate.
• Use continuous lengths of heavy-wall copper tubing,
routed under the floor where possible. Do not attach fuel
lines to the appliance or to floor joists if possible. This will
reduce vibration and noise transmission problems.
• Install an oil filter sized to handle the fuel unit gearset flow
capacity (Table 3) for two-pipe systems. Size the filter for
the firing rate for one-pipe systems. Locate the filter immediately adjacent to the burner fuel unit.
8
• Install two high-quality shut-off valves in accessible locations on the oil supply line. Locate one valve close to the
tank. Locate the other valve close to the burner, upstream
of the fuel filter.

Sequence of operation — typical
1. Standby — The burner is idle, waiting for a call for heat.
When a call for heat is initiated, there is a 2- to 6-second
delay while the control performs a safe start check.
2. Valve-on delay — As applicable, the ignition and motor
are turned on for a 15-second prepurge.
3. Trial for ignition (TFI) — The fuel valve is opened, as
applicable. A flame should be established within the 15second lockout time (30-second lockout time is available).
4. Lockout — If flame is not sensed by the end of the TFI,
the control shuts down on safety lockout and must be
manually reset. If the control locks out three times in a
row, the control enters restricted lockout. Call a qualified
service technician.
5. Ignition carryover — Once flame is established, the
ignition remains on for 10 seconds to ensure flame
stability. It then turns off.
6. Run — The burner runs until the call for heat is satisfied.
The burner is then sent to burner motor-off delay, as
applicable, or it is shut down and sent to standby.
7. Recycle — If the flame is lost while the burner is firing,
the control shuts down the burner, enters a 60-second
recycle delay, and then repeats the ignition steps
outlined above. If the flame is lost three times in a row,
the control locks out to prevent continuous cycling with
repetitious flame loss caused by poor combustion.
8. Burner motor-off delay — If applicable, the fuel valve is
closed and the burner motor is kept on for the selected
postpurge time before the control returns the burner to
standby.

Start the burner
Do not proceed unless all prior steps in this
manual have been completed. Failure to
comply could result in severe personal injury,
death or substantial property damage.
Do not attempt to start the burner when excess
oil has accumulated, when the appliance is
full of vapor or when the combustion chamber
is very hot. Do not attempt to re-establish
flame with the burner running if the flame
should be extinguished during start-up,
venting or adjustment. Allow the unit to cool
off and all vapors to dissipate before
attempting another start. Failure to comply
with these guidelines could cause an
explosion or fire, resulting in severe personal
injury, death or substantial property damage.
If control is not an R7184 refer to
manufacturer’s literature for specific
control.
❏ Starting the burner and venting air
Priming the pump
Resetting from restricted lockout
• If the control locks out three times in a row without a
complete heat cycle between attempts, the lockout
becomes restricted. A qualified service technician
should be called to inspect the burner.
Disable function
• Any time the motor is running, press and hold the reset
button to disable the burner. The burner will remain off
as long as the button is held and will return to standby
when released.
Cad cell resistance check
• While the burner is firing, and after the ignition has been
turned off, press and release the reset button (hold ½second or less) to check the cad cell resistance. The LED
will flash 1 to 4 times, depending on the cad cell
resistance (see the table below). For proper operation, it
is important that the cad cell resistance is below 1600
Ohms.
1. Initiate a call for heat.
2. While the ignition is on, press and release the reset button
(hold ½-second or less). If the control has not locked out
since its most recent complete heat cycle, the lockout time
will be extended to 4 minutes (45 seconds in earlier units),
and the ignition will remain on the entire heat cycle.
3. Bleed the pump until all froth and bubbles are purged. If
prime is not established within the extended lockout time,
the control will lock out. Press the reset button to reset the
control and return to step 2.
The reset button can be held for 30 seconds at
any time to reset the control’s lockout counter
to zero and send the control to standby.
4. Repeat steps 2 and 3, if needed, until the pump is fully
primed and the oil is free of bubbles. Then terminate the
call for heat, and the control will resume normal operation.

❏ Set air adjusting plate
1. Allow the burner to run until the appliance has warmed
sufficiently.
2. Visually check the flame. The flame should not be dark
orange or smoky.
If the flame appears to be smoking, increase the amount
of air by re-adjusting the air band to a higher number.
3. Once the appliance has warmed, the air setting can be
checked and adjusted.
4. Use combustion test instruments to adjust the burner.
a. Adjust the air until a trace of smoke is achieved with
CO2 level as high as possible (lowest possible O2).
Example: 13.5% CO2 (2.5% O2) with a trace of smoke.
5. Check the breech draft pressure against the appliance
6. If the breech pressure is higher or lower than recommended
Maintenance and service
b. Increase the air to reduce CO2 by 2 percentage points
at a zero smoke level. (Increase O2 by 3 percentage
points at a zero smoke level.)
Example: Reduce CO2 from 13.5% to 11.5%, with zero
smoke (or increase O2 from 2.5% to 5.5%).

level, adjust the appliance breech damper to achieve the
specified setting. Recheck the smoke and CO2 levels. Adjust burner air if necessary.
The burner must be serviced at least annually by a qualified service technician to assure continued reliable
operation. Operation and adjustment of the burner requires technical knowledge and the use of combustion test
instruments. Do not tamper with the burner or controls. Failure to comply could result in failure of the burner or
system, resulting in severe personal injury, death or substantial property damage.
Annual service
— by qualified service technician
Have the burner inspected, tested and started at least annually
by a qualified service technician. This annual test/inspection
should include at least the following:
❏ Replace oil nozzle.
❏ Clean burner and blower wheel (if needed to remove
lint or debris).
❏ Test ignition and combustion and verify air settings.
❏ Test oil supply line vacuum - verify that it is within
allowable range indicated in fuel unit literature.
❏ Check pump pressure to nozzle.
❏ Inspect fuel system (including tank, lines and all
connections).
❏ Inspect combustion air and vent systems.
❏ Replace oil filter.
❏ Oil motor (if not permanently lubricated).
Monthly maintenance
— by owner
❏ Observe combustion air openings and vent system for
integrity. Openings must be clean and free of obstructions.
❏ Check oil lines and fittings to verify there are no leaks.
❏ Observe burner ignition and performance to verify
smooth operation.
❏ Shut the system down if you observe abnormal or ques-
tionable operation. Call a qualified service agency for
professional inspection and service.
