Follow These
Instructions Exactly
50 Hz motors — The burner ratings, air settings and nozzle
ratingsarebased onstandard60 hzmotors(at 3450rpm).Derate
all ratings 20% when using 50 hz motors. Consult factory for
specific application data.
NOTICE
High altitude installations — Accepted industry practice
requires no derate of burner capacity up to 2,000 feet above
sea level. For altitudes higher than 2,000 feet, derate burner
capacity 2% for each 1000 feet above sea level.
NOTICE
Pre-installation checklist
The burner cannot properly burn the fuel if it is not
supplied with a reliable combustion air source.
Follow the guidelines in the latest editions of the NFPA
31 and CSA-B139 regarding providing adequate air for
combustion and ventilation.
y
y
Failure to provide adequate air supply could se-
riously affect the burner performance and result
in damage to the equipment, asphyxiation, ex-
plosion or fire hazards.
Adequate Combustion
and Ventilation Air
Supply Required
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
B1139-M91 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.
y

Form 6104BCF5 R09, Printed in the USA 01/08
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.
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.
Refer to the Mount the Burner Section of this manual for
one-pipe or two-pipe fuel supply installation instructions.
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 Bfuel
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.

y
y
y
y
Oil Supply Pressure
Control Required
Damage to the pump, filter or other compo-
nent seals could cause possible oil leakage
and potential fire hazard.
The oil supply inlet pressure to the fuel unit cannot
exceed 3 psig.
Do NOT install valves in return line.
Ensure that a pressure-limiting device is installed in
accordance with the latest edition of the NFPA 31.
y
y
y
Nozzle pressure
The fuel unit nozzle port pressure is factory set at 140
psig. Some original equipment manufacturer burner appli-
cations may call for a lower pressure to obtain a required
firing rate. Do not change this pressure unless directed to
do so by the appliance manufacturer.
Electrical supply
Verify that the power connections available are correct for
the burner. Refer to Figure 1. All power must be supplied
through fused disconnect switches.
Vent system
The flue gas venting system must be in good condition and
must comply with all applicable codes.
y

y

y
Use only nozzles having the brand, flow rate (gph),
spray angle and pattern specified by the appliance
manufacturer.
Follow the appliance manufacturer’s specifications for
the required pump outlet pressure for the nozzle, since
this affects the flow rate.
Nozzle manufacturers calibrate nozzle flow rates at
100 psig.
This burner utilizes pressures higher than 100 psig, so
the actual nozzle flow rate will be greater than the gph
stamped on the nozzle body. (Example: A 4.00 gph
nozzle at 140 psig = 4.70 gph.
For typical nozzle flow rates at various pressures
see accompanying chart.
y
y
y
Incorrect nozzles and flow rates could
result in impaired combustion, under-
firing, over-firing, sooting, puff-back
of hot gases, smoke and potential fire
or asphyxiation hazards.

Figure 3 - Air Tube Mounting Dimensions
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 2. 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.
Two tube arrangements are available –
CF500 1.75 to 5.50 GPH
CF800 Tube A— 3.00 to 7.00 GPH
Tube B— 5.00 to 8.00 GPH
Maximum firing capacity depends on the firebox pressure.
Use Table 2 to verify the correct air tube type for the fir-
ing rate required. Use Tube Bonly when Tube Acannot
provide the firing rate required.
See Figure 3 to verify the correct air tube length and air
tube combination code.

Sequence of operation
— typical
Standby -- The burner is idle, waiting for a call for heat.
When a call for heat is initiated, there is a 3- to 10-second
delay while the control performs a safe start check.
Valve-on delay — As applicable, the ignition and motor are
turned on for a 15-second prepurge.
Trial for ignition (TFI) — The fuel valve is opened, as ap-
plicable. A flame should be established within the 15-second
lockout time (30-second lockout time is available).
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.
Ignition carryover — Once flame is established, the ignition
remains on for 10 seconds to ensure flame stability. It then
turns off.
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.
Recycle — If the flame is lost while the burner is firing, the
control shuts down the burner, enters a 60-second recycle de-
lay, and then repeats the ignition steps outlined above. If the
flame is lost three times in a row, the control locks out to pre-
vent continuous cycling with repetitious flame loss caused by
poor combustion.
Burner motor-off delay — If applicable, the fuel valve is
closed and the burner motor is kept on for the selected post-
purge time before the control returns the burner to standby.
Resetting to cad cell
If the control locks out three times in a row without a com-
plete heat cycle between attempts, the lockout becomes re-
stricted. A qualified service technician should be called to
inspect the burner.

Step 1: Adjust the air shutter/band until a trace of smoke
is achieved.
Step 2: At the trace of smoke level, measure the CO2
(or O2) . This is the vital reference point for further
adjustments. Example: 13.5% CO2(2.6% O2)
Step 3: Increase the air to reduce the CO2by 1.5 to
2 percentage points. (O2will be increased by
approximately 2.0 to 2.7 percentage points.)
Example: Reduce CO2from 13.5% to 11.5% (2.6%
to 5.3% O2).
Step 4: Recheck smoke level. It should be Zero.
This procedure provides a margin of reserve air
to accommodate variable conditions.
If the draft level has changed, recheck the
smoke and CO2(or O2) levels and readjust the
burner, if necessary
Once combustion is set, tighten all fasteners on air band, air
shutter and escutcheon plate.
Start and stop the burner several times to ensure satisfactory
operation. Test the primary control and all other appliance
safety controls to verify that they function according to the
manufacturer’s specifications.
Check the breech draft pressure against the appliance man-
ufacturer’s recommended setting (typically + 0.1” W.C.). If
the breech pressure is higher or lower than recommended
level, adjust the appliance breech damper to achieve the
specified setting. Recheck the smoke and CO2(or O2) levels.
Adjust burner air if necessary.

Annual Professional
Service Required
Annual service — by qualified service techni-
cian
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 the oil supply line filter. The line filter cartridge
must be replaced to avoid contamination of the fuel unit
and nozzle.
Inspect the oil supply system. All fittings should be leak-
tight. The supply lines should be free of water, sludge and
other restrictions.
Remove and clean the pump strainer if applicable.
Replace the nozzle with the exact brand, pattern, gph, flow
rate and spray angle.
Clean and inspect the electrodes for damage, replacing
any that are cracked or chipped.
Check electrode tip settings. Replace electrodes if tips are
rounded.
Inspect the igniter spring contacts.
Clean the cad cell lens surface, if necessary.
Inspect all gaskets. Replace any that are damaged or would
fail to seal adequately.
Inspect the combustion head and air tube. Remove any
carbon or foreign matter. Replace all damaged units with
exact parts.
Clean the blower wheel, air inlet, air guide, burner hous-
ing and static plate of any lint or foreign material.
If motor is not permanently lubricated, oil motor with a
few drops of SAE 20 nondetergent oil at each oil hole.
DO NOT over oil motor. Excessive oiling can cause mo-
tor failure.
Check motor current. The amp draw should not exceed the
nameplate rating.
