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.
Pre-installation check-
list
Protect Against Stray Light Lockout
Failure to follow these instructions could cause loss of burner operation resulting in no heat, an unplanned process interruption, work stoppage and the potential for frozen plumbing or other cold weather property damage.
The control must detect a dark, no-fl ame condition in
y
order to start the burner or it will hold in the stray light lockout mode. Shield the burner view window from direct exposure to
y
intense light.
Protect Against Dust and Moisture
Wet, dusty environments could lead to blocked
air passages, corrosion damage to components, impaired combustion performance and result in asphyxiation, explosion or fi re.
This burner is designed for clean, dry installations.
y
Electrical controls are not protected against rain or
y
sprayed water. Keep the installation clear of dust, dirt, corrosive va-
y
pors, and moisture. Protective covers and more frequent maintenance may
y
be required.
Adequate Combustion and Ventilation Air Supply
Required
Failure to provide adequate air supply could se-
riously affect the burner performance and result in damage to the equipment, asphyxiation, ex­plosion or fi re hazards.
The burner cannot properly burn the fuel if it is not sup-
y
plied with a reliable combustion air source. Follow the guidelines in the latest editions of the NFPA
y
31 and CSA-B139 regarding providing adequate air for combustion and ventilation.
Form 6104 BCF10-R06

Page 6
Combustion air supply
The burner requires combustion air and ventilation air for
y
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 confi ned spaces, the room must have an air opening near the top of the room plus one near the fl oor, 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 NFP A 31 (CSA B1139­M91 in Canada).
If there is a risk of the space being under negative pres-
y
sure 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
y
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
Nozzle pressure
Correct Nozzle and Flow Rate Required
Incorrect nozzles and fl ow rates
could result in impaired combustion, under-fi ring, over-fi ring, sooting, puff-back of hot gases, smoke and potential fi re or asphyxiation haz- ards.
Use only nozzles having the brand, fl ow rate (gph), spray angle and pattern specifi ed by the appliance manufac- turer.
Follow the appliance manufacturer’s specifi cations for the required pump outlet pressure for the nozzle, since this affects the fl ow rate.
Nozzle manufacturers calibrate nozzle fl ow rates at 100
y
psig. This burner utilizes pressures higher than 100 psig, so
y
the actual nozzle fl ow rate will be greater than the gph stamped on the nozzle body. (Example: A 5.00 gph noz­zle at 150 psig = 6.12 gph and at 300 psig = 8.66 gph)
The fuel supply piping and tank must provide #1 or #2 fuel
y
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.
Oil Supply Pressure Con­trol Required
Damage to the pump, fi lter or other compo- nent seals could cause possible oil leakage and potential fi re hazard.
The oil supply inlet pressure to the fuel unit cannot ex-
y
ceed 3 psig. Do NOT install valves in return line.
y y
Ensure that a pressure-limiting device is installed in ac­cordance with the latest edition of the NFPA 31.
If fuel supply is level with or higher than fuel unit
When the fuel unit is not required to lift the oil, the instal-
y
lation 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 8 for one-pipe fuel supply installations. See
y
Figure 9 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
y
oil more than 8 feet if burner is equipped with a B fuel unit, or more than 2 feet if burner is equipped with an H 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.

tighten the nuts on the mounting studs. The burner should be pitched downward 2° as shown in Figures 2 and 3.
See Figure 7. Install the pedestal support kit (recommend-
y
ed) by attaching the ¾” NPT fl ange (item a) to the bottom of the burner using the (4) #10 screws provided. Cut and thread (one end only) a ¾” pipe nipple (item b) with length 10 inches less than dimension D in Figure 7. Thread the pipe into the fl ange. Then slip the pipe end into the fl oor ange (item c).
Secure the burner to the appliance by tightening the nuts on
y
the burner fl ange mounting studs. Then secure the pedestal support fl oor fl ange set screw to the pipe.
Connect Fuel Lines
Fuel unit by-pass plug
Oil supply/return lines
Install the oil tank and oil lines in accordance with all
y
applicable state and local codes. Size the oil supply and return lines using the guidelines
y
given in the fuel unit literature included in the literature envelope. Oil line fl ow rate will equal the burner rate for one-pipe systems. For two-pipe systems, refer to Table 3 for the fuel unit gear set capacity - the rate at which fuel is recirculated when connected to a two-pipe system. Size two-pipe oil lines based on this fl ow rate. Use continuous lengths of heavy-wall copper tubing, routed
y
under the fl oor where possible. Do not attach fuel lines to the appliance or to fl oor joists if possible. This will reduce vibration and noise transmission problems. Install an oil fi lter sized to handle the fuel unit gearset fl ow
y
capacity (Table 3) for two-pipe systems. Size the fi lter for the fi ring rate for one-pipe systems. Locate the fi lter immediately adjacent to the burner fuel unit. Install two high-quality shut-off valves in accessible
y
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 fi lter.
Do Not Install By-pass Plug with 1-Pipe System
Failure to comply could cause immediate pump
seal failure, pressurized oil leakage and the po­tential for a fi re and injury hazard.
The burner is shipped without the by-pass plug in-
y
stalled. Intall the by-pass plug in two-pipe oil supply systems
y
ONLY.
Use a two-pipe system, one-pipe system with by-pass
y
loop, or remove the by-pass plug when using with a one-pipe system and no by-pass loop

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

Prepare the fuel unit for air venting
T o vent air from one-pipe oil systems, attach a clear hose to
y
the vent plug on the fuel unit. Provide a container to catch the oil. Loosen the vent plug. Vent the air as described under Start the burner.
y
Start the Burner
Explosion and Fire Hazard
Failure to follow these instructions
could lead to equipment malfunction and result in heavy smoke emission, soot-up, hot gas puff-back, fi re and asphyxiation hazards.
Do not attempt to start the burner when excess oil has
y
accumulated in the appliance, the appliance is full of vapor, or when the combustion chamber is very hot. Do not attempt to re-establish fl ame with the burner
y
running if the fl ame becomes extinguished during start- up, venting, or adjustment. V apor-Filled Appliance: Allow the unit to cool off and
y
all vapors to dissipate before attempting another start. Oil-Flooded Appliance: Shut off the electrical power
y
and the oil supply to the burner and then clear all ac­cumulated oil before continuing. If the condition still appears unsafe, contact the Fire De-
y
partment. Carefully follow their directions. Keep a fi re extinguisher nearby and ready for use.
y
Starting the burner and venting air
Hot Gas Puff-back and Heavy Smoke Hazard
Failure to bleed the pump properly
could result in unstable combustion, hot gas puff-back and heavy smoke.
Do not allow oil to intermittently spray into a hot com-
y
bustion chamber while bleeding. Install a gauge in the nozzle discharge port tubing or
y
fully open the pump bleed valve to prevent oil spray from accumulating in the combustion chamber when venting air from the fuel pump. Ensure that all bubbles and froth are purged from the
y
oil supply system before tightening the pump air bleed valve.
Verify that the air adjusting plate (Figure 12, item m) has
1. been set to the initial air position as described on page 14 under Initial air settings.
Open the oil shut-off valves in the oil supply (and return)
2. line(s) to the burner.
Form 6104 BCF10-R06
Set the thermostat (or operating control) to call for heat.
3.
Close the line switch to the burner. The burner motor should
4. start immediately.
15
Page 16
If the burner motor does not start, reset the motor overload
5. switch (if so equipped) and press the reset switch of the burner primary control.
V ent the fuel unit as soon as the burner motor starts rotating.
6. To vent —
Attach a clear plastic tube to the air bleed valve (Figure
8 or 9 as applies, item p). Place the end of the tube in a container to catch the oil.
Then loosen the fuel unit air vent valve. Tighten the air vent valve after all air has been purged.
IF burner stops during venting —
The burner primary control will lockout if fl ame is not
y
established within its time limit. This is typically 15 seconds for R7184B primary controls, but may be less for other fl ame supervisory controls. The burner may lockout several times during the period
y
needed to purge all the air. Press the red reset button for ½ second during the prepurge cycle to extend air venting time.
IF burner stops after fl ame established —
Additional venting is probably required. Repeat the
y
air venting procedure.
7. Once fl ame is steady, proceed to Set air adjusing plate.
Set air adjusting plate (Figure 12)
Allow the burner to run until the appliance has warmed
1. sufciently.
Visually check the fl ame. The fl ame should not be dark
2. orange or smoky. If the fl ame appears to be smoking, increase the amount of air by re-adjusting the damper indicator to a higher number.
Once the appliance has warmed, the air setting can be
3. checked and adjusted.
Use combustion test instruments to adjust the burner.
4.
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.
b. Increase the air to reduce CO
at a zero smoke level. (Increase O points at a zero smoke level.)
Example: Reduce CO
zero smoke (or increase O2 from 2.5% to 5.5%).
c. This procedure provides a margin of reserve air to ac-
commodate variable conditions.
Check the breech draft pressure against the appliance
5. manufacturer’s recommended setting (typically + 0.1” W.C.).
If the breech pressure is higher or lower than recommend-
6. ed level, adjust the appliance breech damper to achieve the specifi ed setting. Recheck the smoke and CO2 levels. Adjust burner air if necessary and tighten the air adjust­ing plate screw securely.

Maintenance and Service
Inspect the igniter spring contacts.
Annual Professional Service Required
Tampering with or making incorrect
adjustments could lead to equipment malfunction and result in asphyxia­tion, explosion or fi re.
Do not tamper with the burner or controls or make
y
any adjustments unless you are a trained and qualifi ed service technician. To ensure continued reliable operation, a qualifi ed
y
service technician must service this burner annually. More frequent service intervals may be required in dusty
y
or adverse environments. Operation and adjustment of the burner requires technical
y
training and skillful use of combustion test instruments and other test equipment.
Annual service — by qualifi ed service techni-
cian
Have the burner inspected, tested and started at least annually by a qualifi ed service technician. This annual test/inspection should include at least the following:
Replace the oil supply line fi lter. The line fi lter cartridge
must be replaced to avoid contamination of the fuel unit and nozzle. Inspect the oil supply system. All fi ttings 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, fl ow
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.
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 car-
bon or foreign matter. Replace all damaged units with exact parts. Clean the blower wheel, air inlet, air guide, and burner
housing 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 motor failure. Check motor current. The amp draw should not exceed the
nameplate rating. Check all wiring for secure connections or insulation
breaks. Check the pump pressure and cutoff function.
Check primary control safety lockout timing.
Check ignition system for proper operation.
Inspect the vent system and chimney for soot accumulation
or other restriction. Clean the appliance thoroughly according to the manufac-
turer’s recommendations. Check the burner performance. Refer to the section “Set
combustion with test instruments”. It is good practice to make a record of the service performed
and the combustion test results.
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 fi ttings to verify there are no leaks.
Observe burner ignition and performance to verify smooth operation.
Shut the system down if you observe abnormal or questionable operation. Call a qualifi ed service agency for professional inspection and service.
