INSTALLATION and OPERATING INSTRUCTIONS

EQUIPMENT SELECTIONAn accurate heating load calculation must be conductedusing American Society of Heating, Refrigeration andAir Conditioning Engineers (ASHRAE) or AirConditioning Contractors of America (ACCA) manuals.Do not add a large safety factor above the calculatedvalue. If the calculated heating load requirementexceeds the heating capacity rating of a given model,use only the next larger size available. Never increaseby any more than absolutely necessary based uponavailable equipment heating capacities. Always selectbased upon heat capacity (output), never use inputcapacities.

NOTE: It is the personal responsibility and obligationof the purchaser to contract a qualifiedinstaller to assure that installation is adequateand is in conformance with governing codesand ordinances.

LOCATING THE FURNACEWhen installing the furnace be sure to provide adequatespace for easy service and maintenance. Locate thefurnace as close to the chimney as practical, givingconsideration to the accessibility of the oil burner,controls, and blower for service. Allow a minimum of24 inches at front of furnace for servicing oil burner.Allow adequate room for filter and blowermaintenance. Clearance from combustible material asstated on the furnace and repeated in Table 1 must bemaintained. For damp basement installations, a raisedconcrete pad is recommended. This will help keep thebottom of the furnace dry and reduce rusting.

An oil burner must have a generous supply ofcombustion air to operate properly. The flow ofcombustion and ventilating air must not be obstructedfrom reaching the furnace. See “Ventilation andCombustion Air” section.

The furnace area must be kept clear and free ofcombustible materials, gasoline and other flammablevapors and liquids.

This unit is not designed for mobile home or trailerinstallations. Always install furnace in a level position.

� For the first three (3) feet from plenum. After three (3) feet, no clearance required.C Combustible flooring

NC Noncombustible floor* Maintained on one side or the other to achieve filter access and/or blower service.

** Floor must be noncombustible. For furnace only installation can be installed on combustibleflooring only when installed on special base part no. CFB7 available from factory. When airconditioning coil cabinet DCB23-22 is used then use special base part no. CFB23.

DUCT WORKThe air distribution system should be designed andinstalled in conformance with manuals published by AirConditioning Contractors of America (ACCA) as setforth in Manual D, or ASHRAE publications.

When the furnace is used in connection with a coolingunit*, the furnace shall be installed parallel with or onthe upstream side of the cooling unit to avoidcondensation in the heating element. With a parallelflow arrangement, the dampers or other means used tocontrol flow of air shall be adequate to prevent chilledair from entering the furnace, and if manually operated,must be equipped with means to prevent operation ofeither unit, unless the damper is in the full heat or coolposition.

* A cooling unit is an air conditioning coil, heat pumpcoil or chilled water coil.

See CFM versus static pressure tables on pages 23-26for additional information.

INADEQUATE SUPPLY AIR and/or RETURNAIR DUCT SYSTEMS

Short cycling because of limit control operation can becreated by incorrectly designed or installed supply and/or return air duct systems.

The duct systems must be designed using ASHRAE orACCA design manuals and the equipment CFM andexternal static pressure ratings to insure proper airdelivery capabilities.

INSTALLING THE FURNACEA typical installation is shown in Figure 4. All parts ofthe furnace installation (furnace, oil tank and pipingsystems, combustion and ventilation air, venting, etc.)must comply with NFPA31, Installation of Oil BurningEquipment -- latest edition. This drawing shows thetypical connecting parts needed to correctly install thisfurnace. Make sure that all parts of the heating systemcomply with the local codes.

Check the furnace and your load calculation to verifythat the unit is properly sized. (Refer to EquipmentSelection” section on Page 2.)

The correct size of unit needed may be substantiallysmaller than the unit being replaced due to homeimprovements and technology advancements since theinitial installation.

WIRING

FACTORY

All units are fully factory wired. Multispeed blowersare factory wired on high speed for cooling/manual fanoperation. Heating speeds are wired for the largestinput and may need lower speed for field installed lowinput nozzle. If replacement wire is necessary, use 105degrees C minimum. See electrical data, Table 5.

FIELD

All wiring must conform to the National ElectricalCode and all local codes. A separate fuse or breakershould be used for the furnace.

IMPORTANTWhen a furnace is installed so that supplyducts carry air circulated by the furnace toareas outside the space containing thefurnace, the return air must also be handledby a duct(s) sealed to the furnace casing andterminating outside the space containing thefurnace This is to prevent drawing possiblehazardous combustion products into thecirculated air.

On replacement installations, particularly if equipmentis oversized, the duct systems can easily be undersized.Modifications may be required to assure that theequipment is operating within the approvedtemperature rise range when under full rated inputconditions, and that no short cycling on limit controls isoccurring.

OIL LINE PIPINGFirst determine whether the pipe system is to be a singleline system or a two line system. All connections mustbe absolutely air tight or you will have a malfunction ofthe burner. When installing the piping, a good oil filtershould be installed close to the burner. A single linesystem is recommended for gravity feed.

A typical single inside tank installations shown inFigure 5. For installation details for this and other tankconfigurations, refer to NFPA31 -- latest edition. Alltank and pipe setups must comply with NFPA31.

BECKETT AFG OIL BURNERThis furnace is equipped with a high static Beckett AFGoil burner which is designed to produce adequate draftin nearly any vertically vented application. The burneremployees the latest time tested controls of the highestquality. The controls consist of a high voltage Beckettsolid state igniter, a Beckett “CleanCut” oil pump withan integral solenoid valve, and a Beckett R7184Bprimary control.

These controls were selected for their proven highquality, dependability, and serviceability. With propermaintenance this burner assembly will provide manyyears of reliable service.

All units are shipped with the oil burner installed, andwith high rate oil nozzle installed designed for use withNo. 1 or No. 2 fuel oil. Inspect firepot refractorybefore firing to be sure it has not been jarred out ofposition in shipment. Burner air tube must notextend beyond inside surface of firepot. Burnerhead should be centered on the combustion chamberopening. See Figures 16A and 16B.

FIGURE 5TYPICAL SINGLE INSIDE TANK INSTALLATION

WARNINGNever attempt to use gasoline in your furnace.Gasoline is more combustible than fuel oil andcould result in a serious explosion causingdamage, injury or death.

MIS-1340


The following is a detailed explanation of each controlincluded in the Becket AFG Oil Burner, how eachoperates, how to set up the burner, and how totroubleshoot problems should they occur.

BECKETT “CLEANCUT” OIL PUMPThis oil pump is equipped with an oil solenoid valveinstalled in the pump housing. This feature providesquick cutoffs resulting in reduction in smoke after theburner shuts down. This is a time proven pump designand is capable of both one and two pipe systems. Thispump requires a pre-purge style primary control such asthe R7184B primary. All installation and set upinstructions are outlined in the “Oil PumpSpecification” section of the installation instructionsmanual.

As an improved service feature Bard Manufacturing hasinstalled a brass tee fitting next to the oil line output ofthe pump for installing a pressure gauge to ensure thecorrect pump pressure. Refer to the “Burner Set Up andAdjustment” section in the manual.

BECKETT SOLID STATE IGNITERThis igniter differs from the traditional iron coretransformer in that it produces a 14,000 volt sparkinstead of a 10,000 volt spark of the iron core

BECKETT R7184B PRIMARY CONTROLThe R7184B Interrupted Electronic Oil Primary is aline voltage, safety rated, interrupted ignition oilprimary control for residential oil burners. The R7184Bused with a cad cell flame sensor, operates the oilburner and oil valve. The primary controls fuel oil,senses flame, controls ignition spark and is designed tonotify a remote alarm circuit before going into lockoutwhen equipped with a flame monitoring system.

This primary control, though it possesses the latesttechnology, is a very simple control to operate andprovides additions troubleshooting features to easeservice and reduce down time. Once the features andoperation of this control are understood the serviceperson will find it a welcomed addition. In an effort tohelp in the transition to the R7184B primary control theoperational guide is provided following on Page 10.

transformer. This hotter spark provides for cleaner,faster ignitions. Being solid state technology thisigniter is less susceptible to problems caused by voltagevariations. It also has a greater ability to ignite coldand/or inconsistent oil. The solid state igniter is wiredto the primary control the same as a standard iron coretransformer.


BECKETT R7184B PRIMARY

OPERATIONAL GUIDE

Pre-Purge Delay – 15 seconds on delay

LED Codes – Flashing 1/2 second on / 1/2 second off – system is locked out or in restricted mode(hard lockout).

– Flashing 2 seconds on / 2 seconds off – control is in recycle mode (soft lockout).

– ON – CAD cell is sensing flame

– OFF – CAD cell is not sensing flame.

Future Option – Flame Quality MonitorThis control is trained to recognize and remembera good flame based on initial burner set up.Control then monitors the flame via the CAD cellsignal for deviation in the combustioncharacteristics of the burner. If the control sensesa deviation on the high side or on the low sidefrom the original set up condition for threeconsecutive cycles, it will trigger an alarm circuitwhich can be tied to an audible local device tosignal the home owner or into the home security

system. Upon being notified of the of the alarm,the security agency will notify the dealer of choicebased upon information supplied by the homeowner. The system will also be capable of beingconnected to a phone line that will contact thedealer directly with the alarm. This alarm willtypical sound 3 to 5 days prior to the primarycontrol going into lockout giving the serviceagency a prior notice before a sooting condition orother failure can occur resulting in untold savings.

Ignition Trials – On any given call for heat thecontrol will allow three ignition trials. After thethree trials the control will go into a soft lockoutmode. The LED will flash 2 seconds on and 2seconds off when in this recycle mode. Thecontrol may then be reset by pressing the REDreset button on the control. If within the sameoriginal call for heat the control will again allowthree ignition trials followed by another softlockout and a 2 second on / 2 second off LEDcode. The control my be reset one additional timeby pressing the red reset button. This will allow

three final ignition trials. If all three of the finalignition trials fail then the control goes into a hardlockout or Restricted Mode. This series of ignitionfailures must all occur with the original call forheat in order to reach the Restricted Mode. TheLED will now flash 1/2 second on / 1/2 second offindicating the restricted mode. The control can beresurrected from the restricted mode only bypressing and holding the red reset button forapproximately 30 seconds until the LED flashestwice. Removing unit power or resetting thethermostat will not reset the control

Checking CAD Cell – With a call for heat and the burner ignited, press and release the red reset button.The LED will go out and then flash 1, 2, 3, or 4 times before returning to the run mode. The CAD cellresistance must be below 1600 ohms for proper operation.

– 1 flash – Less than 400 ohms

– 2 flashes – More than 400 and less than 800 ohms




BURNER SETUP AND ADJUSTMENTSAll oil burner installations should be performed by aqualified installer in accordance with regulations of theNational Fire Protection Standard for Oil-BurningEquipment, NFPA31 -- latest edition, and in completecompliance with all local codes and authorities havingjurisdiction. A qualified installer is an individual oragency who is responsible for the installation andadjustments of the heating equipment and who isproperly licensed and experienced to install oil-burningequipment in accordance with all codes and ordinances.

The proper installation and adjustment of any oil burnerrequires technical knowledge and the use of combustiontest instruments. The following procedure must befollowed to correctly adjust the burner to match thespecific characteristics of the installation.

CHECK AND ADJUSTMENT PROCEDURE:

1. Check all oil lines and connections for leaks.

2. Connect pressure gauge to pressure gauge port inbrass tee fitting. See Figure 6.

3. Operate the burner for 5 - 10 minutes so that thesystem is near steady state temperature conditions.

4. Check fuel pump pressure, and adjust to 100 PSIGif necessary.

5. Set the overfire draft to -.02” W.C. by adjusting thebarometric damper. The sample tube can beinserted into the heat exchanger over thecombustion chamber by loosening the two (2)screws securing the sliding door on the hingedburner observation door.

6. A small diameter hole will be required in the fluepipe between the flue connection on the furnaceand the barometric damper for purposes of takingthe smoke tests and measuring the CO

2 (or O

2) and

flue gas temperature.

7. The burner air adjustment shutters are factory set tothe recommended start up settings as shown inTable 9. These settings are for initial start up only.Reduce or increase the air supply until a trace ofsmoke is obtained on the smoke tester. This is areference point only not the final adjustment.

IMPORTANTAlways use combustion test instruments whenmaking burner adjustments and draft gaugewhen setting the barometric damper. It isvirtually impossible to make accurate andreliable adjustments using the “eyeball”method.


8. Measure the CO2 (or O

2) in the flue gas at the trace

of smoke level. Open the air control and addreserve air until the CO

2 is lowered by 1.5%.

Example: Original CO2 at trace of smoke level was

13.0% (3.30% O2). Lower to 11.5% CO

2 (5.3% 0

2).

See Table 7.

9. Perform the smoke test again. It should now be atzero. Lock the air settings securely.

10. Measure the stack temperature. Subtract the roomtemperature to obtain the net reading and use theEfficiency Chart, Table 8, to determine the steady-state efficiency.

IMPORTANTDo not set the blower “on” set point lever ofthe combination fan/limit control above 150.

LOUVERS AND GRILLESIn calculating free area for above ventilation andcombustion air requirements, consideration shall begiven to the blocking effect of louvers, grilles, orscreens protecting openings. Screens used shall not besmaller than 1/4 inch (6.3 mm) mesh and shall bereadily accessible for cleaning. If the free area througha design of louver or grille is known, it shall be used incalculating the size opening required to provide the freearea specified. If the design and free area is not known,it may be assumed that wood louvers will have 30-35percent free area and metal louvers and grilles will have60-75 percent free area.

VENTINGThe flue pipe to the chimney must be the same size asthe flue outlet of the furnace, have no reductions, be ofa corrosion-resistant material, and have an upward pitchof 1/4” for every foot of horizontal run. A barometricdamper is supplied with the furnace and should beinstalled in the flue pipe observing the instructionspackaged with the damper control. The barometricdamper opening must be located in the sameatmospheric pressure zone as the combustion air inlet tothe furnace. This furnace must not be vented into thesame chimney with any solid fuel burning appliance.Masonry chimneys must be lined with a listed system orother approved material that will resist corrosion,softening, or cracking from flue gas at temperatures upto 1800° F. See Standard for Installation of Oil BurningEquipment NFPA31 and Standard for ChimneysNFPA211 for additional information.

THERMOSTATNOTE: FC models do not wire directly to the

primary control. See wiring diagram onPage 33.

These furnaces are designed to be controlled with any24V heating or heating/cooling thermostat. Theheat/cool thermostats must be designed for independentheat/cool transformer circuits to assure that the 24Vtransformer built into the oil primary control does notconflict with the main furnace 24V transformer. Theheat anticipator should be set at 0.20A. This is anominal setting. The thermostat circuit should bechecked to verify setting.

FAN AND LIMIT CONTROLThe fan and limit control is factory installed in all units.See Table 13 for factory settings. The fan on/offsettings may have to be varied due to the static pressureimposed upon the system. The limit control is factoryset at maximum fixed stop allowable and must not bereset.

When the installation is completed, measure the airtemperature in the discharge plenum and return airplenum. The temperature rise across the unit shouldfall within the “Rise Range” as shown in Table 13. It isnormally desirable to operate in the middle of the rangeunless air conditioning or other installationrequirements make that unfeasible. The speed of theblower may have to be either increased or decreased toobtain this temperature. The blower is equipped with a3 or 4 speed motor to make these adjustments.

The fan and limit control in the burner compartmentgoverns the blower operation by means of twotemperature selections. One lever is set at 140 degreesfor example to start the blower, and the other lever is ata lower temperature, 110 degrees to stop the blower.These settings may be varied to suit the homeowner’scomfort. A greater temperature difference betweensettings may result in less repetition of the bloweroperation at the end of the heating cycle. A low “off”temperature is recommended for longer bloweroperation as this keeps the air of the home in moreconstant circulation.

NOTE: On model FC085D36D the blower “on”setting is timed to assure blower operation.This blower “on” setting cannot be adjusted.

COUNTERFLOW MODELS – FILTERLOCATIONSCounterflow models normally have filters installed inthe return air plenum above the furnace unless acommon return air/filter grille is used.

The electrical switch should be turned “off” before thefront door to furnace is removed. After removing thefront door, remove the left side filter door in the uppersection of the furnace. Refer to Figure 14 for properfilter locations.

Figure 13 shows a typical installation of a 20 x 25 x 1filter rack. The same 14 x 23 cutout is required in thefurnace side, and the bottom of the filter rack is alignedover the bottom of the 14 x 23 cutout. The top of thefilter rack rises approximately 6 inches above the top ofthe cutout. The 3 inch depth of the filter rack providesample spacing between furnace side and leaving edge offilter for the entire filter surface to be effective.

To remove filter from the filter rack (see Figures 12 &13), remove the filter access cover and grasp the end ofthe filter.

This filter is the high velocity type foam filter whichmay be washed and used over and over. Do not replaceit with a fiberglass disposable filter of the same size.

To replace filter, reverse the above procedure.

MAINTENANCE

INSPECT AIR FILTERWashable air filters are supplied with each furnace.Washable filters should not be replaced with disposabletype. Clean filters before each heating season begins.It is recommended that filters also be cleaned at leasttwice during the heating season.

Be sure the new filters are set securely in the filter rackso there can be no leakage around them. (Seeinstructions on inside of blower compartment door.)

FINAL INSPECTION AND TESTFinal inspection and test of an installation shall bemade to determine that the work has been done in fullaccordance with regulations and according to thehighest standards for safety, performance andappearance. Such an inspection and test shouldindicate the following as a minimum:

1. Determine that all parts of the oil storage andcirculating system, including tank, piping andburner, are free from oil leaks. Be sure that no oildischarges from the nozzle when burner is notoperating.

2. Be sure that the suction line and pump have beenentirely vented of air so that the burner hasinstantaneous oil shutoff at the nozzle and so thatthe pump operates without an air noise.

3. Check the flame adjustment to determine that theflame is clear, quiet, free of odor and oil nozzle isof proper size for the furnace.

4. Test operation of burner by operating thethermostat. First, set the thermostat above roomtemperature. Burner should start. Second, setthermostat below room temperature. Burner willstop.

5. Check operation of burner primary control inaccordance with manufacturer’s instructionsincluded with the control. Following is the methodwe recommend in checking the safety switch inthis primary control.

A. Flame Failure – Simulate by shutting off oilsupply manual valve while burner is on.Within 9 seconds the control will shut theburner down and flash a diagnostic code of1/2 second on / 1/2 second off. Ignition andmotor stop and oil valve closes

B. Ignition Failure – Test by closing oil supplywhile burner is off. Run through startingprocedure. The primary control will attemptthree trials for ignition. After three attempts,the control will lockout.

C. Power Failure – Turn off power supplywhile burner is on. When burner goes out,restore power and burner will restart.

D. If operation is not as described, check wiringand installation first. If trouble appears to bein the control circuit, replace the flamedetector. If trouble still persists, refer to“Common Causes of Trouble” section onpage 26.

SERVICE HINTSPreventive maintenance is the best way to avoidunnecessary expense, inconvenience, and retainoperating efficiency of your furnace. It is advisable tohave your heating system and burner inspected atperiodic intervals by a qualified serviceman. If troubledevelops, follow these simple checks before calling theserviceman.

1. Make sure there is oil in tank and valve is open.

2. Make sure thermostat is set above roomtemperature.

3. Make sure electrical supply to furnace is on andfuses are not blown or circuit breakers tripped.

4. Reset safety switch of burner primary control.

CAUTIONReset three (3) times only. More than threeresets can cause excessive oil to be pumpedinto combustion chamber which could result inexplosion upon ignition.

5. Press thermal protector button of burner motor.

6. Make sure air filters are in place and are clean.

7. Make sure all air openings in furnace, allventilation and combustion air openings, all returnair grilles, and all warm air registers areunobstructed and open.


COMBINATION COMBUSTIONCHAMBER/BURNER MOUNTINGSYSTEMThe furnace has been designed with a combustionchamber mounting system that enables servicepersonnel to remove the combustion chamber, itsmounting system, and burner assembly as one unit forinspection and/or service on the bench. It has also beendesigned to remove the burner assembly independentlyfrom the mounting system to perform basic annualservice and inspection. The mounting system iscompletely adjustable so exact alignment between theburner tube and combustion chamber may be assuredprior to installation into the furnace. See Figure 16Aand 16B.

WARNINGThe procedures described in Figures 16A and16B should be conducted only by a qualifiedservice technician.

Improper servicing could cause electric shockhazard, fires or explosion resulting in damage,injury or death.

PUMP SQUEALS OR CHATTERS

This may be caused by air in pipes. Check all joints inthe oil supply pipe for leaks. Check strainer in pump; ifdirty, clean.

INSUFFICIENT HEAT

Check limit control setting. It may be that flame is notallowed to stay on long enough to generate sufficientheat in furnace to heat the house properly. If the propersize furnace has been selected according to houserequirements and satisfactory heat is not obtained,recheck the heating plant for size and capacity inrelation to house. Check for clogged filters.

Check and make sure the heat anticipator on thethermostat is set correctly.

CARE OF FINISHYour unit is painted with baked enamel. Like a goodpiece of furniture, it has an excellent appearance and anoccasional waxing and dusting will keep it attractive foryears.

CLEANING OF FURNACEAll of these units have two clean out plugs for easycleaning of the heat exchanger. They are accessiblefrom the front of these units by removing the clean outaccess cover in the burner compartment. The furnaceshould be check annually by a qualified servicetechnician.

WARNINGUnder no circumstance should a sootdeterioration device be used in thecombustion chamber. These products knownas “soot busters” or “soot sticks” arecomprised of chemicals that burn at very hightemperatures which may exceed thetemperature rating of the combustion chambermaterial.

Use of these products are detrimental to thelife expectancy of the combustion chamberand will destroy the chamber. Refer to the“Cleaning of Furnace” section for propercleaning methods.

COMMON CAUSES OF TROUBLE

CAUTIONTo avoid accidents, always open main switch(OFF position) when servicing the burner.

BURNER WILL NOT PRODUCE FLAME

Check oil level gauge to see that there is sufficient oil intank or tanks. Check the burner mounted relay control.Do not adjust this control.

Check position of electrodes – incorrect position willcause slow or delayed ignition. Clean electrodes andnozzle. Check and clean strainer in pump. If oil linefilter is used, check filter condition.

If burner runs but there is no flame the fuel pump maybe air bound. Follow instructions for bleeding fuelpump.

Check and make sure the solenoid valve on the oilpump is being energized and opening.

BURNER STARTS OR STOPS TOO OFTEN

Limit control may be set too low. Make sure set pointindicator is against limit stop on dial. Refer to ratingplate for limit setting. Check heat anticipator setting onthermostat.

NOZZLE PRODUCES A STRINGY FLAME

Worn tangential grooves in nozzle. Replace nozzle.

BASEMENT TANK HUM

Occasionally with a two-pipe installation there may bea low return line hum. Eliminate hum by installing aspecial anti-hum valve in the return line near pump.

HEAVY FIRE OR PULSATING FLAME.

These may occur after burner starts. It may be causedby a slight oil leak in the fuel pump and cannot becorrected except by replacing the pump. This happensonly when the burner is started.

CHATTERING SOUND OR HIGH PITCH NOISE

This noise from motor can usually be traced to where aconduit or BX cable is fixed rigidly or attached to somepart of the building. Relieving this strain may eliminatenoise.
