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 Fuel Gas Code NFPA 54/CSA B149. 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 1000 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
The unit must be installed with minimum clearances of 16 inches on the sides, 12 inches from the top of
the unit, 16 inches from the flue (venting), 48” from the front, 0” from the floor, 48” from ductwork and 36
inches from the burner access side. The unit must be installed on a level floor.
DUCT INSTALLATION
- Duct diameter is 20 inches
- Use belt cuff ducting. Slide the cuff overtop of the duct inlet/outlet and tighten with the belt.
- The top two connections are the heated supply air into the building.
- The bottom two duct connections are for cold air or return air into the heater.
- The heater is approved use with or without ducting.
- Maximum duct length is 100 feed per supply opening. If return air ducting is used the length of
the return air duct must be subtracted form the allowable supply ducting length (i.e. if the return
air duct length is 30 feet the maximum supply duct length is reduced to 70 feet).
- Ducts should be rated for 300 F. minimum.
HIGH LIMITS
- The heater is supplied with manual reset high limits located behind marked panels on the left
side of the heater
- The high limit contacts are normally closed and open on the over temperature condition
- If a high limit trips allow the heater to cool down and then reset the high limit by manually
depressing the reset button located in the centre of the high limit.

VENT SYSTEM
The flue gas venting system must be in good condition and must comply with all the applicable codes.
OUTDOOR INSTALLATIONS:
For outdoor installation, vent cap must be installed and fastened.
INDOOR INSTALLATIONS:
Must be done in accordance to NFPA 54 (or CSA B149) with local authorities having jurisdictions.
1. The flue must be securely attached to the unit with tight joints.
2. The flue must not be sized to have a cross-sectional area less then that of the flue
collar at the unit.
3. Other appliances must not be connected so as to vent through the vent of this unit.
4. Do not use 90-degree tees or elbows greater than 45 degrees.
5. Do not support the weight of the stack on the flue connection of the heating system.
6. The maximum flue gas temperature is 650 F. “A” vent, or single wall steel pipe must
be used.
7. Minimize connecting pipe length and the number of bends by locating the unit as close
to the flue pipe as possible.
8. Maintain clearances between the flue pipe and combustible materials that are
acceptable to the Federal, Provincial and local authorities having jurisdiction.
9. Unit must be connected to a flue having sufficient draft to ensure proper operation of
unit.
VERTICALLY VENTED UNITS
1. Maximize the height of the vertical run of
vent pipe. A minimum of five (5) feet
(1.5m) of vertical pipe is required. The
top of the vent must extend at least two
(2) feet (0.61m) above highest point on
the roof. A weatherproof vent cap must
be installed to the vent termination.
2. Horizontal runs must not exceed 75% of
the vertical height of the vent pipe, up to
a maximum of ten (10) feet (3m).
Horizontal runs should be pitched upward
¼” per foot
(21 mm) and should be supported at 3
foot (1m) maximum intervals.
3. Design vent pipe to minimize the use of
elbows. Each 90 is equivalent to 5 feet
(1.5m) of straight vent pipe run.
4. Vent pipe should not be run through
unheated spaces. If such runs cannot be
avoided, insulate vent pipe to prevent
condensation inside vent pipe. Insulation
should be a minimum of ½” (12.7mm)
thick foil faced fibreglass, minimum 1 ½#

INSTALLING THE OPTIONAL THERMOSTAT
Plug the thermostat directly into the receptacle. WARNING: THE RECEPTACLE IS USED FOR
INSTALLING THE THERMOSTAT ONLY! THIS IS NOT A POWER SOURCE.
CONNECT THE FUEL LINE(S) - REFER TO CHART BELOW FOR FUEL LINE LENGTH
WARNING Install the oil lines using the following guidelines. Failure to comply could lead to equipment
damage and present a risk of sever 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 pipes dope. Never use Teflon tape. Tape strands
can break free and damage the fuel unit.
On two-pipe oil systems verify that the suction line vacuum does not exceed the fuel
manufacturer's recommendation.
WARNING Do not operate the burner unless a return line or a by-pass loop is installed. Failure to
follow this guideline will cause damage to the fuel seals and consequent fuel leakage. This
could result in severe personal injury, death or substantial property damage.
OIL SUPPLY / RETURN LINES
Install the oil tank lines in accordance with all applicable codes.
Use continuous lengths of heavy wall copper tubing, routed under the floor, where possible. Do not attach
fuel lines to the fuel unit or to the floor joists if possible. This reduces vibration and noise transmission
problems.
Install a high quality shut-off valve in an accessible location on the oil supply line. Locate one valve close
to the tank.

SEQUENCE OF OPERATION – TYPICAL
1. Turn the unit switch to manual.
2. Power is applied to the R7184B black wire (BK).
3. After 10 seconds, the F7184B applies 120 volts to the orange wire (OR),
activating the burner motor (M1) and the ignition transformer (TR). The oil
pump is operated by the burner-motor, so oil pressure is delivered to the oil
valve inlets.
4. Power is applied to the oil valve circuit. After a ten second pre-purge. When
the timer times out, oil valves (S1 and S3) are activated, allowing oil to flow to
the nozzle.
5. Trail for ignition (TFI). A flame should be established within the 15-second
lockout time. If no flame is sensed after 15 seconds, the R7184B will terminate
all power to the blower and oil circuits, shutting the burner down. The control
will electrically lock out and has to be manually reset. If the control locks out
three times in a row, the control enters restricted lockout. Call a qualified
service technician.
6. After the flame is established, there is a 30 second warm-up. After the 30
seconds the main blower starts.
7. When the call for heat signal terminates (at the black wire of the R7184B), the
R7184B terminates power to all circuits, closing the oil valves and stopping the
burner motor. The main blower motor stays in operation for 3 minutes, then the
blower shut down.
(Optional)
If a thermostat is used, the thermostat is plugged into the receptacle on the side of unit. The sensor unit
should be placed in the heated space. On a call for heat the unit will be activated as above.

PREPARE THE BURNER FOR START-UP
Start-up checklist – Verify the following before attempting to start burner
o Combustion air supply and venting have been inspected and verified to be free of obstruction
and installed in accordance with all applicable codes.
o Fuel connection to nozzle line assembly is secure.
o Fuel supply line is correctly installed, the oil tank is sufficiently filled, and shut-off valves are
open.
START THE BURNER
WARNING 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.
WARNING 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 flames 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.
AIR SETTING
The low fire cam should be set at 30 and the
high fire cam at 45. Refer to figure shown below.
In some cases these air-setting needs to be adjusted.
To do this insert your flue gas analyzer into the flue, 6 inches above the top of unit.
Measure you excess O2% and CO2% levels. Set your air shutter to bring your O2% levels
between 5-6%. Your CO2% will be between 9-10% and your CO levels should be around
zero. Alternately, set the burner for #1 smoke spot on the Bacharach scale.

INITIAL AIR SETTINGS
If your burner was built for a specific OEM (Original
Equipment Manufacturer) application, the manufacturer
will indicate the initial air settings made at Beckett.
Please verify those settings using the following procedure.
The following steps outline the procedure for initially setting
the damper (these settings may be different from
settings specific to a particular OEM).
Remove the cover screw (A) then the cover (B) and
set aside.
Push in on pin (B) to disengage the motor from the
damper shaft and cam stack. Rotate the damper
shaft by hand to place the adjustment cams in a
position where their adjustment scale can be easily
seen. Release pin (G) to secure the damper shaft
and cam stack to the motor.
Using the wrench (C) supplied with the damper
motor, adjust the blue low fi re cam (D) to the initial
setting listed in Table 4.
Using the same wrench, adjust the red high fi re
cam (H) to the initial settings listed in Table 4.
To adjust the high fi re transition, use a small straight
edge screwdriver. Turn the white adjustment screw
located in the orange transition cam (J) until the
cam indicator is half way between the high and low
settings on the scale.
After setting all the cams, make sure the damper
shaft and cam stack is set between its low fi re
setting and its high fi re setting. (If you don’t it may
not move when it is powered.) Push in pin (G),
move the damper by hand so that notch (E) is
between the low fi re setting and high fi re setting
on scale (F), then release pin (G) to re-engage the
motor. When the motor is powered it will go to its
low fi re setting.
This initial setting should be adequate for starting the
burner at low fi re. Once the burner is in operation,
the air setting will be adjusted for best performance as
discussed later in this manual. Don’t forget to re-install
the cover after all adjustments have been made.
The damper plate is attached
by screws to its shaft, and bears
against a fl at on the shaft for alignment. The shaft is
secured to the damper motor by a sleeve coupling with
two setscrews bearing against the damper shaft and two
more against the motor shaft. The motor shaft has a
fl at matching the one on the damper shaft. The fl ats on
the damper shaft and the motor shaft should be aligned
so that the position indicator in the damper motor reads
accurately. The best way to align the fl ats is to tighten
the set screws that bear against the fl ats on the shafts
fi rst, and then tighten the ones that bear against the
round surface of the shafts afterward.
The test for proper alignment is to disengage the damper
motor from its shaft using the disengaging pin (Item G in
Figure 17) and rotate the damper plate to its full closed
position. The position indicator should point to 0° within
+ 5° tolerance.

SET “Z” DIMENSION
The air slider (z dimensions) settings should be set at 2 on the drawer assembly, which is located
on the right hand side of the burner.
Replace the rear access door on the burner, making sure that the adjusting plate assembly is seated in
the recessed area in the housing. Loosen acorn nut (item c) and spline nut (item b). Move nozzle line to
the head setting #2 and tighten acorn nut (item c) and spline nut (item b).

MAINTENANCE AND SERVICE
WARNING 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 or the burner or system, resulting in severe personal injury,
death or substantial property damage.
ANNUAL SERVICE
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:
o Clean burner and blower wheel (to remove lint and debris).
o Test ignition and combustion and verify air damper settings.
o Test fuel lines and all connections
o Inspect combustion air and vent systems.
o Oil motor (if not permanently lubricated).
MONTHLY MAINTENANCE
o Observe combustion air openings and vent system for integrity. Openings must be clean
and free of obstructions.
o Check the fuel lines and fittings to verify there are no leaks.
o Observe burner ignition and performance to verify smooth operation.
o Shut the system down if you observe abnormal or questionable operation. Call a
qualified service agency for professional inspection and service.
o Grease the main supply blower bearings.
CLEANING THE HEAT EXCHANGER
To clean the secondary of heat exchanger remove the clean out panel located above the burner. This
gives you access to the heat exchanger. Remove the exchanger panel and flue baffles. With a brush
clean out the secondary walls. When re-installing the exchanger panel replace the gasket and re-apply
high temperature silicone rated to 800F. To clean out the main drum, remove the burner and with a brush
clean the sides of the drum. To re-install the burner replace the gasket and insure the burner inserts into
the exchanger 3 ¾ inches. Run the unit at full fire.
12

INSTALL NOZZLE
Install the oil nozzle in the nozzle adaptor. Use a ¾” open-end wrench to steady the nozzle adaptor and
use a 5/8” open-end wrench to turn the nozzle. Tighten securely but do not over-tighten.
Verify that the oil tube assembly and electrodes are in good condition, with no cracks or damage.
WARNING Failure to properly set and maintain the electrode and nozzle spacing dimensions can
cause incorrect burner ignition or poor combustion. This could result in severe personal
injury, death or substantial property damage.
13

BEARING INSTALLATION AND MAINTENANCE
NOTE: To prevent premature failure – please ensure greasing instructions below are applied. As well,
tighten bearing set screws, collars, and wheel lugs every four to six months.
ENGINEERING – BALL & ROLLER BEARINGS LUBRICATION
For bearings that are equipped with a hydraulic grease fitting threaded into the housing for ease of
lubrication, the proper amount of lubricant in the bearing is important. Both excessive and inadequate
lubrication may cause failure. The bearings should be re-lubricated while they are rotating (if it is safe to
do so); the grease should be pumped in slowly until a slight bead forms around the seals. The bead in
addition to acting as an indicator of adequate re-lubrication provides additional protection against the
entry of foreign matter and helps flush out contaminates in the bearing.
By the time the slight bead is formed, it will be noticed that the bearing temperature will rise. It is not
uncommon for the temperature to rise as much as 30 degrees Fahrenheit after re-lubrication. If
necessary to re-lubricate while the bearing is idle, refer to the recommended re-lubrication grease chart
tables on the following page for various sizes of the bearings.
LUBRICANT-STANDARD BEARINGS:
All bearing units are pre-lubricated at the factory with a lithium soap grease which is compatible with
multi-purpose grease readily available from local suppliers. The lubricant selected for factory lubrication
uses a highly refined mineral oil with a high viscosity index, thickened with lithium soap to conform to
NLGI grade 2 consistency. A suitable additive package is added to protect the highly polished rolling
contact surfaces from corrosion and oxidation of the lubricant. The lubricant is satisfactory for an
operating temperature range of –30 F to +250 F.
Select standard industrial grade greases that conform to the following specification for optimum bearing
performance:
General Duty Ball & Roller;
58-75 SUS @ 210 F
450-750 SUS @ 100 F
Premium Duty Ball & Roller;
68-75 SUS @ 210 F
600-750 SUS @ 100 F
Heavy Duty Roller Bearing;
82 SUS @ 210 F
886 SUS @ 100 F
NOTE: For heavy loaded roller bearing applications, grease with EP additives are often recommended
for optimum performance.
14

TABLE I. RECOMMENDED LUBRICATION
Frequency of re-lubrication depends upon operating conditions. The bearing operating temperature is the
best index for determining a re-lubrication schedule. The following chart gives the frequency of re-lubrication
based upon continuous operation for various operating temperatures and can be used as a satisfactory guide
for determining when bearings should be re-lubricated.

TENSIONING V-BELT DRIVES
1. Ideal tension is the lowest tension at which the belt will not slip under peak load conditions.
2. Check tension frequently during the first 24-48 hours of operation.
3. Over-tensioning shortens the belt and bearing life.
4. Keep belts free from foreign material that may cause slip.
5. Make V-drive inspection on a periodic basis. Tension when slipping. Never apply belt dressing
as this will damage the belt and cause early failure.
Check and tighten belt tension. The following procedure is recommended for tightening belts:
a) Measure span “X” shown in Figure A.
b) At the center of span length “X”, apply a force perpendicular to the span and large enough to deflect
belt 1/64” for each inch of span length. Example- the required deflection for a 40” span would be
40/64” or 5/8”.
c) Compare the force applied with the values given in Table III. If force is between the minimum and
maximum range shown, the drive tension should be satisfactory. A force below the minimum value
indicates an under tightened belt and force that exceeds the maximum value indicates an over
tightened belt.

three minute cool down period the supply fan shuts down.
3. SYSTEM SWITCH “THERMOSTAT” (the Heat Switch is inoperative in this mode)
On a call for first stage heat from the thermostat, after a ninety second purge period, the burner fires on
low fire. Thirty seconds after the burner fires the supply fan starts. On a call for second stage heat from
the thermostat the burner goes to high fire. When the call for heat from the thermostat is satisfied the
burner and supply fan shut down.
4. SYSTEM SWITCH “OFF”
The heater is inoperative.
NOTES:
- When the “VENTILATION SWITCH” is in the “ON” position the supply fan will run continuously.
- When the system switch is turned off the supply fan will continue to run for three minutes to cool down
the heat exchanger
- Do not shut down the heater by disconnecting the power supply to the heater as this could damage the
heater. To shut down the heater turn the SYSTEM SWITCH to the “OFF” position and wait for the three
minute cool down cycle to complete before disconnecting the power supply.
SEQUENCE OF OPERATION
BECKETT GENISYS 7505
Burner States
1. Standby: The burner is idle, waiting for a call for heat.
2. Valve-on Delay: The igniter and motor are on while the control delays turning on the oil solenoid valve
for the programmed time (45 seconds).
3. Trial for ignition: The oil solenoid valve is energized. A flame should be established within the factory
set trial for ignition time (”lockout time”).
4. Lockout: The control has shut down for one of the following safety reasons:
a. The trial for ignition (lockout) time expired without flame being established
b. The cad cell detected flame at the end of the Valve on Delay state.
To reset the control from lockout click the button 1-second.
NOTE: A recurrence of the above failure modes or a failed welded relay check could cause the control to
enter a Hard Lockout state that must be reset only by a qualified service technician.
To reset from Hard Lockout, hold the reset button for 15 seconds until the yellow light turns on.
5. Ignition Carryover: Once flame is established, the igniter remains on for 10 additional seconds to
ensure flame stability.
6. Run: The flame is sustained until the call for heat is satisfied. The burner is then sent to Motor-Off
Delay, if 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 repeats the ignition sequence. The control will continue to Recycle each time
the flame is lost, until it reaches a pre-set time allotment. The control will then go into a Hard Lockout
instead of recycle. This feature prevents excessive accumulation of oil in the appliance firing chamber.
8. Motor-Off Delay: If applicable, the oil solenoid valve is turned off and the control delays turning the
motor off for the set motor-off delay time before the control returns to standby.
9. Pump Prime: The igniter and motor are on with the oil solenoid valve energized for 4 minutes. During
Pump Prime mode, the cad cell is disregarded, allowing the technician to prime the pump without having
to jumper the cad cell.

RESET BUTTON OPERATION
Table 2 explains what action the control will take when the reset button is pressed for different lengths of
time during the various burner operating states.
Priming th Pump
1. Prepare the burner for priming by attaching a clear plastic hose over the bleed port fitting and fully
opening the pump bleed port. Use a suitable container to collect purged oil.
WARNING 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 spray into a hot combustion chamber while bleeding air from the pump.
