INST ALLATION and OPERA TING INSTRUCTIONS

EQUIPMENT SELECTION

An accurate heating load calculation must be conducted
using American Society of Heating, Refrigeration and
Air Conditioning Engineers (ASHRAE) or Air
Conditioning Contractors of America (ACCA) manuals.
Do not add a large safety factor above the calculated
value. If the calculated heating load requirement
exceeds the heating capacity rating of a given model,
use only the next larger size available. Never increase
by any more than absolutely necessary based upon
available equipment heating capacities. Always select
based upon heat capacity (output), never use input
capacities.

NOTE: It is the personal responsibility and

obligation of the purchaser to contract a
qualified installer to assure that installation
is adequate and is in conformance with
governing codes and ordinances.

LOCATING THE FURNACE

When installing the furnace be sure to provide adequate
space for easy service and maintenance. Locate the
furnace as close to the chimney as practical, giving
consideration to the accessibility of the oil burner,
controls, and blower for service. Allow a minimum of
24 inches at front of furnace for servicing oil burner.
Allow adequate room for filter and blower
maintenance. Clearance from combustible material as

stated on the furnace and repeated in Table 1 must be
maintained. For damp basement installations, a raised

concrete pad is recommended. This will help keep the
bottom of the furnace dry and reduce the risk of rusting.

An oil burner must have a generous supply of
combustion air to operate properly. The flow of
combustion and ventilating air must not be obstructed
from reaching the furnace. See “Combustion Air
Requirements” section.

The furnace area must be kept clear and free of
combustible materials, gasoline and other flammable
vapors and liquids.

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

INSTALLING THE FURNACE

INSTRUMENTS REQUIRED FOR PROPER
SETUP OF THE FURNACE

It is important that a set of instruments capable of the
following requirements be used for the setup of this
furnace to ensure proper and safe operation:

1. Oil pump pressure gauge that measures up to
150 PSI.

2. Smoke gun to pull smoke samples from flue.

3. Draft gauge that will measure -.02” water column
(W.C.)

4. Duct static pressure gauge 0-1.0” W.C. range.

5. Temperature gauge that can read from 50° F up to
700° F.

6. A gauge to measure CO2 or O2.

DUCT WORK

The air distribution system should be designed and
installed in conformance with manuals published by Air
Conditioning Contractors of America (ACCA) as set
forth in Manual D, or ASHRAE publications.

IMPORTANT

When a furnace is installed so that supply
ducts carry air circulated by the furnace to
areas outside the space containing the
furnace, the return air must also be handled
by a duct(s) sealed to the furnace casing and
terminating outside the space containing the
furnace This is to prevent drawing possible
hazardous combustion products into the
circulated air.

INSTALLATION

A typical installation is shown in Figures 4 and 5. All
parts of the furnace installation (furnace, oil tank and
piping systems, combustion and ventilation air, venting,
etc.) must comply with NFPA31, Installation of Oil
Burning Equipment -- latest edition. This drawing
shows the typical connecting parts needed to correctly
install this furnace. Make sure that all parts of the
heating system comply with the local codes.

Check the furnace and your load calculation to verify
that the unit is properly sized. (Refer to Equipment
Selection” section on Page 2.)

The correct size of unit needed may be substantially
smaller than the unit being replaced due to home
improvements and technology advancements since the
initial installation.

INADEQUATE SUPPLY AIR and/or RETURN
AIR DUCT SYSTEMS

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

The duct systems must be designed using ASHRAE or
ACCA design manuals and the equipment CFM and
external static pressure ratings to insure proper air
delivery capabilities.

On replacement installations, particularly if equipment
is oversized, the duct systems can easily be undersized.
Modifications may be required to assure that the
equipment is operating within the approved

temperature rise range when under full rated input
conditions, and that no short cycling on limit controls is

occurring.

INSTALLING A COOLING UNIT

When the furnace is used in connection with a cooling
unit*, the furnace shall be installed parallel with or on
the upstream side of the cooling unit to avoid
condensation in the heating element. With a parallel
flow arrangement, the dampers or other means used to
control flow of air shall be adequate to prevent chilled
air from entering the furnace, and if manually operated,
must be equipped with means to prevent operation of
either unit, unless the damper is in the full heat or cool
position.

* A cooling unit is an air conditioning coil, heat

pump coil or chilled water coil.

When installing a cooling unit above an FH or FL
(below on an FC) series furnace, the coil must be
spaced far enough from the furnace outlet to assure
proper operation of the furnace. Bard supplied coils,
when used with Bard supplied coil cabinets, are
automatically positioned.

For top discharge FH and FL models, when coils are
installed without using Bard coil cabinets or coils of
another brand are used, the coil drain pan should be
located a minimum of two (2) inches above the top of
the furnace cabinet. If a greater clearance is specified
by the coil manufacturer then it would apply.

NOTE: IF DRAIN PAN IS ANYTHING OTHER

THAN A STEEL PAN PARTICULAR
ATTENTION MUST BE GIVEN TO THE
INSTALLATION INSTRUCTIONS FOR
THE COIL TO MAKE SURE IT IS
ACCEPTABLE FOR USE WITH THESE
OIL FURNACES HAVING MAXIMUM
OUTLET AIR TEMPERATURE OF 200° F.

See CFM versus static pressure curves on pages 33-36
for additional information.

OIL LINE PIPING

First determine whether the pipe system is to be a single
line system or a two line system. All connections must
be absolutely air tight or you will have a malfunction of
the burner. When installing the piping, a good oil filter
should be installed close to the burner. A single line
system is recommended for gravity feed.

A typical single inside tank installations shown in
Figure 6. For installation details for this and other tank
configurations, refer to NFPA31 -- latest edition. All
tank and pipe setups must comply with NFPA31.

These controls were selected for their proven high
quality, dependability, and serviceability. With proper
maintenance this burner assembly will provide many
years of reliable service.

All units are shipped with the oil burner installed, and
with high rate oil nozzle installed designed for use with
No. 1 or No. 2 fuel oil. Inspect firepot refractory

before firing to be sure it has not been jarred out of
position in shipment. Burner air tube must not
extend beyond inside surface of firepot. Burner
head should be centered on the combustion chamber
opening. See Figures 19 and 20.

WARNING

Never attempt to use gasoline in your furnace.
Gasoline is more combustible than fuel oil and
could result in a serious explosion causing
damage, injury or death.

BECKETT SOLID STATE IGNITER

This igniter differs from the traditional iron core
transformer in that it produces a 14,000 volt spark
instead of a 10,000 volt spark of the iron core
transformer. This hotter spark provides for cleaner,
faster ignitions. Being solid state technology this
igniter is less susceptible to problems caused by voltage
variations. It also has a greater ability to ignite cold
and/or inconsistent oil. The solid state igniter is wired
to the primary control the same as an iron core
transformer.

BECKETT R7184B PRIMARY CONTROL

The R7184B Interrupted Electronic Oil Primary is a
line voltage, safety rated, interrupted ignition oil
primary control for residential oil burners. The R7184B
used with a cad cell flame sensor, operates the oil
burner and oil valve. The primary controls fuel oil,
senses flame, controls ignition spark and is designed to
notify a remote alarm circuit before going into lockout
when equipped with a flame monitoring system.

The following is a detailed explanation of each control
included in the Becket AFG Oil Burner, how each
operates, how to set up the burner, and how to
troubleshoot problems should they occur.

BECKETT “CLEANCUT” OIL PUMP

This oil pump is equipped with an oil solenoid valve
installed in the pump housing. This feature provides
quick cutoffs resulting in reduction in smoke after the
burner shuts down. This is a time proven pump design
and is capable of both one and two pipe systems. This
pump requires a pre-purge style primary control such as
the R7184B primary. All installation and set up
instructions are outlined in the “Oil Pump
Specification” section of the installation instructions
manual.

This primary control possesses the latest technology, is
a very simple control to operate and provides additional
troubleshooting features to ease service and reduce
down time. The operational guide for the R7184B
primary control is provided following on
Page 12.

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.

Ignition Trials – On any given call for heat the
control will allow three ignition trials. After the three
trials the control will go into a soft lockout mode. The
LED will flash 2 seconds on and 2 seconds off when
in this recycle mode. The control may then be reset
by pressing the RED reset button on the control. If
within the same original call for heat the control will
again allow three ignition trials followed by another
soft lockout and a 2 second on / 2 second off LED
code. The control my be reset one additional time by
pressing the red reset button. This will allow three
final ignition trials. If all three of the final ignition trials

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 cell resistance
must be below 1600 ohms for proper operation.

– 1 flash – Less than 400 ohms
– 2 flashes – More than 400 and less than 800 ohms
– 3 flashes – More than 800 and less than 1600 ohms
– 4 flashes – More than 1600 and less than 5000 ohms

Burner Option – Flame Quality Monitor
This control is trained to recognize and remember a
good flame based on initial burner set up. Control
then monitors the flame via the CAD cell signal for
deviation in the combustion characteristics of the
burner. If the control senses a deviation on the high
side or on the low side from the original set up
condition for three consecutive cycles, it will trigger
an alarm circuit which can be tied to an audible local
device to signal the home owner or into the home
security system. Upon being notified of the of the

fail then the control goes into a hard lockout or
Restricted Mode. This series of ignition failures must
all occur with the original call for heat in order to
reach the Restricted Mode. The LED will now flash
1/2 second on / 1/2 second off indicating the
restricted mode. The control can be resurrected from
the restricted mode only by pressing and holding the
red reset button for approximately 30 seconds until
the LED flashes twice. Removing unit power or
resetting the thermostat will not reset the control

alarm, the security agency will notify the dealer of
choice based upon information supplied by the home
owner. The system will also be capable of being
connected to a phone line that will contact the dealer
directly with the alarm. This alarm will typical sound
3 to 5 days prior to the primary control going into
lockout giving the service agency a prior notice
before a sooting condition or other failure can occur
resulting in untold savings. This monitor system is
available through your local distributor under the
Honeywell part no. QS7100F.

Electronic Blower Control Board (EBC)

This furnace is equipped with an Electronic Blower
Control (EBC) which controls all comfort air blower
operations. This EBC has three relays; one for
heating speed, one for cooling speed, and one which
isolates the T–T signal from the oil primary control.

This EBC is designed to be very simple and
dependable. This basic control allows for easy
troubleshooting and maintenance. As illustrated in
Figure 7 all connections are well marked. The

BURNER SETUP AND ADJUSTMENT
PROCEDURES

All oil burner installations should be performed by a
qualified installer in accordance with regulations of the
National Fire Protection Standard for Oil-Burning
Equipment, NFPA31 -- latest edition, and in complete
compliance with all local codes and authorities having
jurisdiction. A qualified installer is an individual or
agency who is responsible for the installation and
adjustments of the heating equipment and who is
properly licensed and experienced to install oil-burning
equipment in accordance with all codes and ordinances.

The proper installation and adjustment of any oil burner
requires technical knowledge and the use of combustion
test instruments. The following procedure must be
followed to correctly adjust the burner to match the
specific characteristics of the installation.

1. PREPARATION STEPS

A. Calibrate and Check Operation of

Measuring Equipment Follow
manufacturer’s recommended procedures for
calibration and equipment check out.

B. Prepare Heating Unit for Testing Drill two

1/4 inch holes in the flue between the heating
plant and the barometric draft regulator. If
space permits, the holes should be located in a
straight section of the flue, at least two flue
diameters from the elbow in the flue pipe and at
least one diameter from the draft regulator. The
purpose of the two holes in the flue pipe is to
speed up testing and reduce instrument
handling.

C. Clean and Seal Heating Plant Make sure the

burner blast tube, fan housing, and blower
wheel are clear of dirt and lint. Seal any air
leaks into the combustion chamber.

Always use combustion test instruments when
making burner adjustments and draft gauge
when setting the barometric damper. It is
virtually impossible to make accurate and
reliable adjustments using the “eyeball”
method.

Check all oil lines and connections for leaks.
Connect pressure gauge by removing bleed fitting and

screwing in pressure gauge. See Figure 9.

Manual 2100-422
Page 14

D. Nozzle Inspection Annual replacement of

nozzle is recommended. The nozzle size
should match the design load . DO NOT
OVERSIZE. (Determination of oversizing can
be determined prior to your adjustment. If the
firing rate should be reduced refer to Table 4.)
Short cycles and low percent :on: time result in
higher overall pollutant emissions and lower
thermal efficiency. An in-line oil filter will
reduce service problems due to nozzle clogging.

It should be located as close as possible to the
oil burner. Care should be taken to prevent air
leakage in the oil suction line. Use continuous
runs of copper tubing and use minimum
number of joints and fittings. Always use flare
fittings.

E. Adjustment of Electrodes Adjust ignition

electrodes as specified in Figure 10.

F. Operate Burner Operate burner, adjust air

setting for good flame by visual observation,
and run for at least 10 minutes or until
operation has stabilized.

G. Check Burner Pressure Bleed air from

pump and nozzle piping. Check pump pressure
and adjust to 100 psi, if necessary.

2. COMBUSTION ADJUSTMENT STEPS

H. Set Draft Check the draft reading over the

fire with a draft gauge through a hole in the
inspection door. The hole is above the flame
level. Adjust the barometric draft regulator on
the flue to give the over fire of -.02” W.C.

I. Check Smoke Readings After burner has

been operating 5 or 10 minutes, make a smoke
measurement in the flue, following the smoke
tester instructions. Oily or yellow smoke spots
on the filter paper are usually a sign of
unburned fuel, indicating very poor
combustion (and likely high emissions of
carbon monoxide and unburned hydrocarbons.)
This condition can sometimes be caused by too
much air, or by other factors. If this condition
cannot be corrected, major renovation or even
burner replacement may be necessary.

J. Develop Smoke - CO2 Curve Record

measurements of smoke and CO

from the

2

flue. Then establish the smoke - CO2 curve by
taking readings over a range of air settings, as
shown in Figure 8.

To do this, start with the air gate set at nearly
full open and then take smoke and CO
readings at progressively lower air settings, as
necessary to visualize the general shape of the
curve. (The CO2 readings will increase as the
air setting is decreased, unless combustion is
incomplete.) Do not set the air gate to give a
smoke reading above No. 4 or No. 5. Plot the
points on graph paper, as in Figure 8. Usually
3 or 4 readings are enough to establish the
curve.

In adjusting each air setting, it is helpful to
note the various positions of air gate at which
measurements are made so that the final setting
can be located quickly.

K. Adjust Air Setting Examine the smoke - CO

2

plot and, keeping in mind the curve of
Figure 6,note the location of the “knee” where
the smoke number begins to rise sharply.
Noting the air gate position marks, adjust the
air setting to a CO

level 1/2 to 1 percent lower

2

than the CO2 level at the “knee”. (This
provides a tolerance against possible shifts in
the setting over a period of time.) Do not
increase the air setting any more than necessary
on the lower portion of the curve below the
“knee”

The characteristic curve for some burners may
not yield a distinct “knee” in the curve. In such
cases, the setting should be made near the
minimum smoke, (using judgement).

Lock the air adjustment and repeat draft,
CO2 and smoke measurements to make sure
the setting has not shifted.

3. COMBUSTION DIAGNOSIS

L. Check Performance A well-matched and

well-tuned burner should be capable of
operation with smoke not greater than No. 2
and at a CO2 level not less than 10%.

If this cannot be reached, check the following:

1. Air leaks into the combustion chamber or
heat exchanger can dilute the combustion
gases and prevent normal CO2 readings.
Such leaks should be sealed with furnace
cement or other high-temperature sealant.

To check for dilution by leakage, measure
the CO2 at as high a point as possible over
the fire, using a stainless steel tube
inserted through the fire door sample hole
(as described earlier for overfire draft
measurements), and compare this with the
CO2 measured in the flue. A difference of
more than 1 percent CO2 between the flue
and overfire reading usually indicates air
entry through leaks that have not been

2

properly sealed.
Seal between the probe and inspection door

sample hole during test. The inspection
door hole should be sealed when not being
used to avoid leakage of air through it.
(See Step H.)

2. If the CO2 level of 10% cannot be reached
without exceeding No. 2 smoke, poor
mixing of air and fuel is likely.

It may be necessary to replace the
combustion head or try different settings.

Manual 2100-422
Page 15

4. FINAL CHECKS

M. Measure Stack Temperature Operating the

unit at an excessive firing rate will generate
more heat than the heat exchanger can utilize
and result in unnecessary heat loss up the
chimney. Other causes of excessive heat loss
are badlysooted heat exchanger surfaces and
excessive draft. The temperature of the flue gas
provides an indication of these heat losses.

Measure flue temperature by subtracting the
room air temperature from the thermometer
reading. Excessive stack loss is indicated of the
net stack temperature during steady operation
exceeds 600° F.

N. Check Ignition Check operation over repeated

cycles to insure prompt ignition on starting.

O. Check Pump Cutoff Slow pump cutoff at the

end of a firing cycle can cause smoke and other
pollutant emissions. Check for prompt pump
cutoff by observing flame or by testing smoke at
shutdown. If poor cutoff is observed, make sure
air is purged from the pump and nozzle line.
Air trapped in the pump or nozzle line will
expand when heated, thus causing oil to drip
into the combustion chamber after shutdown. If
poor cutoff persists, repair or replace pump.
Also make sure the pump solenoid is working.
If not replace.

SHORT FORM ADJUSTMENT
PROCEDURE

Some burner service organizations may wish to
perform a shorter procedure for the adjustment of oil
burners. The following is an example of such a short
form prepared by the National Association of Oil Heat
Service Managers.

1. SERVICE AND CLEAN BURNER

Follow company procedure to complete the
cleaning and servicing. Operate burner for ten
minutes while tools are gathered and are cleaned.

2, CHECK DRAFT

Set draft regulator, if necessary. Regulator should
be adjusted to achieve a -.02” W.C. over fire
condition. The more restricted and lengthy the
flue, the higher the draft necessary to obtain the
accepted over fire conditions.

3. SMOKE TEST

Follow the instructions of the manufacturer of the
smoke tester and take a smoke sample. Adjust the
air to obtain a preliminary reading of about No. 3
spot. Then readjust the air to obtain the lowest
possible reading, but do not open the air
adjustment more than absolutely necessary to
obtain a trace or No. 0 spot.

4. CO2 TEST

Check CO2 levels. This level should be between
10% and 12%.

SPACING OF ELECTRODES

The electrodes should be spaced 5/32” apart. They
should extend 1/16” beyond the end and 5/16” above
the center of the nozzle tip as shown in Figure 10.

GUN ASSEMBLY ADJUSTMENT

The gun assembly can be adjusted in the slot inside of
fan housing by loosening screw holding slot cover in
position. Nozzle tip should ordinarily be located 1-1/8”
behind the front face of the cone.

REMOVING GUN ASSEMBLY

Disconnect the oil line at the fan housing and remove
lock nuts on copper tube fitting. Loosen igniter hold
down clamps, then swing igniter up and backward. Gun
assembly can now be removed through this opening.

COMBUSTION AIR REQUIREMENTS

This furnace must be installed in a location where a
sufficient supply of combustion air is available for the
complete combustion of the fuel oil. Keep in mind that
a certain amount of excess air is required as well to
ensure complete combustion of the fuel oil.

When structures are constructed too tightly to supply
sufficient combustion air, air from outside the structure
is required to be brought in directly to the furnace. This
furnace has been conveniently designed to accept a
combustion air boot which is attached directly to the
outdoors by means of a 4” pipe. This pipe can be rigid
or flexible, but it is recommended that a metallic
material be used. Refer to Figure 11. The air boot used
for this design is a Field Controls model number
CAS-2B-90E that can be purchased through your local
distributor. Follow all installation procedures as
specified in the instructions packaged with the air boot
kit.

In unconfined spaces in buildings, infiltration may be
adequate to provide air for combustion, ventilation, and
dilution of flue gases. However, in buildings of
unusually tight construction, additional air shall be
provided using the method described under “All Air
From Outdoors” in Figure 13.

An unconfined space (such as an open basement) must
have a minimum volume of 50 cubic feet per 1,000
BTUH of total of all appliances in area. Adjoining
rooms may be counted as one area only if there are not
doors between the rooms.

Shown in Table 8 are the required minimum areas in
square feet to qualify as an unconfined space for
various total BTUH input ratings. The table is based on
a room(s) with 8 foot ceiling heights.

If the unconfined space is within a building having
insufficient air because of tight construction, the air for
combustion and ventilation shall be obtained from
outdoors or from spaces freely communicating with the
outdoors. Under these conditions a permanent opening
or openings have a total free area of not less than one
square inch per 5,000 BTU per hour (28 square inches
per hour ) of total input rating of all appliances shall be
provided. For combustion air options see Page 20,

LOUVERS AND GRILLES

In calculating free area for ventilation and combustion
air requirements, consideration shall be given to the
blocking effect of louvers, grilles, or screens protecting
openings. Screens used shall not be smaller than 1/4
inch (6.3 mm) mesh and shall be readily accessible for
cleaning. If the free area through a design of louver or
grille is known, it shall be used in calculating the size
opening required to provide the free area specified. If
the design and free area is not known, it may be
assumed that wood louvers will have 30-35 percent free
area and metal louvers and grilles will have 60-75
percent free area.

A barometric damper is supplied with the furnace and
must be installed in the flue pipe observing the
instructions packaged with the damper control. The
barometric damper opening must be located in the same
atmospheric pressure zone as the combustion air inlet to
the furnace. The furnace must not be vented into the
same chimney with any solid fuel burning appliance
such as a wood burner or pellet burner. Masonry
chimneys must be lined with a listed system or other
approved material that will resist corrosion, softening or
cracking from flue gas temperatures up to 1800° F. See
Standard for Installation of Oil Burning Equipment
NFPA31 latest edition and Standard for Chimneys
NFPA211 latest edition for additional information.

VENTING OPTIONS

This furnace is designed to be vented conventionally
into a vertical chimney or horizontally through a side
wall with an optional Field Controls side wall power
venting system.

Note that the FH, FC and FLF series furnaces have been
designed to allow for bringing the vent system through
the cabinet side for increased venting flexibility. To
take advantage of this feature, simply remove the
desired knockout from either side or top of unit and
rotate flue box accordingly by removing four (4) screws
under cleanout plate as shown in Figure 4. Make sure
smoke pipe gasket is in place before reinstalling flue
box screws.

VERTICAL VENTING

If the unit is to be vertically vented make sure the flue
pipe from the furnace to the chimney is the same size
diameter as the flue outlet of the furnace which is 6”.
The flue pipe must have no reductions in diameter, be
made of a corrosion-resistant material having an
upward pitch of 1/4” for every foot of horizontal run,
and be made of material capable of handling
temperatures up to 1800° F.

HORIZONTAL VENTING

This furnace is designed to be horizontally vented
through a side wall with an optional side wall power
vent. The recommended side wall venter is the Field
Controls model number SWG-4HDS for 085 and 110
models, and SWG-5S for 140 models only. This venter
can be purchased through your local distributor. Follow
all installation instructions packaged with the venter
system.

THERMOSTAT

These furnaces are designed to be controlled with any
24V heating or heating/cooling thermostat. The
heat/cool thermostats must be designed for independent
heat/cool transformer circuits to assure that the 24V
transformer built into the oil primary control does not
conflict with the main furnace 24V transformer. The
heat anticipator should be set at 0.20A. This is a
nominal setting. The thermostat circuit should be
checked to verify setting.

AIR FIL TERS

Only Lo-Boy models are shipped with air filters. Filter
kits are available from your local distributor for Upflow
and Counterflow models. Knockouts are provided in
the sides of the FH series models to facilitate the
cutting of the return openings.

The upflow filter kit part numbers are FR23 for a
16x25x1 filter size and FR24 for a 20x25x1 filter size.
These filter kits come complete with the filter and all
necessary brackets for installing on the furnace. Each
comes with a washable aluminum mesh filter. When
installing a five ton AC unit on the furnace, one FR24
or Two FR23 must be used due to the high airflow
requirements. It is important to note that a minimum of
one inch spacing is required between the filter and the
unit side. Do not exceed 400 fpm for fiberglass
(disposable) type filters and 575 fpm for washable type
filters. See Figure 16.

The counterflow filter kit part number FR25 comes
with two washable filters. If not installing the FR25 kit
remember not to exceed 400 fpm for fiberglass
(disposable) type filters and 575 for washable type
filters. See Figure 17.

MAINTENANCE

LUBRICATION

No lubrication is required for either the burner or the
blower motor. Both are permanently lubricated.

INSPECT AIR FILTER

Replace filters before each heating season begins. It is
recommended that filters also be replaced at least twice
during the heating season.

Be sure the new filters are set securely in the filter rack
so there can be minimal leakage around them.

FINAL INSPECTION AND TEST

Final inspection and test of an installation shall be
made to determine that the work has been done in full
accordance with regulations and according to the
highest standards for safety, performance and
appearance. Such an inspection and test should
indicate the following as a minimum:

1. Determine that all parts of the oil storage and
circulating system, including tank, piping and
burner, are free from oil leaks. Be sure that no oil
discharges from the nozzle when burner is not
operating.

2. Be sure that the suction line and pump have been
entirely vented of air so that the burner has
instantaneous oil shutoff at the nozzle and so that
the pump operates without an air noise.

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

4. Test operation of burner by operating the
thermostat. First, set the thermostat above room
temperature. Burner should start. Second, set
thermostat below room temperature. Burner will
stop.

5. Check operation of burner primary control in
accordance with manufacturer’s instructions
included with the control. Following is the method
we recommend in checking the safety switch in
this primary control.

A. Flame Failure – Simulate by shutting off oil

supply manual valve while burner is on.
Within 9 seconds the control will shut the
burner down and flash a diagnostic code of
1/2 second on / 1/2 second off. Ignition and
motor stop and oil valve closes

B. Ignition Failure – Test by closing oil supply

while burner is off. Run through starting
procedure. The primary control will attempt
three trials for ignition. After three attempts,
the control will lockout.

C. Power Failure – Turn off power supply

while burner is on. When burner goes out,
restore power and burner will restart.

D. If operation is not as described, check wiring

and installation first. If trouble appears to be
in the control circuit, replace the flame
detector. If trouble still persists, refer to
“Common Causes of Trouble” section on
page 28.

SERVICE HINTS

Preventive maintenance is the best way to avoid
unnecessary expense, inconvenience, and retain
operating efficiency of your furnace. It is advisable to
have your heating system and burner inspected at
periodic intervals by a qualified serviceman. If trouble
develops, follow these simple checks before calling the
serviceman.

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

2. Make sure thermostat is set above room
temperature.

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

4. Reset safety switch of burner primary control.

CAUTION

Reset three (3) times only. More than three
resets can cause excessive oil to be pumped
into combustion chamber which could result in
explosion 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, all
ventilation and combustion air openings, all return
air grilles, and all warm air registers are
unobstructed and open.

COMBINATION COMBUSTION
CHAMBER/BURNER MOUNTING
SYSTEM

The furnace has been designed with a combustion
chamber mounting system that enables service
personnel to remove the combustion chamber, its
mounting system, and burner assembly as one unit for
inspection and/or service on the bench. It has also been
designed to remove the burner assembly independently
from the mounting system to perform basic annual
service and inspection. The mounting system is
completely adjustable so exact alignment between the
burner tube and combustion chamber may be assured
prior to installation into the furnace. See Figure 19
and 20.

COMMON CAUSES OF TROUBLE

CAUTION

PUMP SQUEALS OR CHATTERS

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

To 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 in
tank or tanks. Check the burner mounted relay control.
Do not adjust this control.

Check position of electrodes – incorrect position will
cause slow or delayed ignition. Clean electrodes and
nozzle. Check and clean strainer in pump. If oil line
filter is used, check filter condition.

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

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

BURNER STARTS OR STOPS TOO OFTEN

Check heat anticipator setting on thermostat.

NOZZLE PRODUCES A STRINGY FLAME

Worn tangential grooves in nozzle. Replace nozzle.

BASEMENT TANK HUM

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

HEAVY FIRE OR PULSATING FLAME.

These may occur after burner starts. It may be caused
by a slight oil leak in the fuel pump and cannot be
corrected except by replacing the pump. This happens
only when the burner is started.

CHATTERING SOUND OR HIGH PITCH NOISE

This noise from motor can usually be traced to where a
conduit or BX cable is fixed rigidly or attached to some
part of the building. Relieving this strain may eliminate
noise.

INSUFFICIENT HEAT

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

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

CARE OF FINISH

This furnace cabinet is made with a very durable and
corrosion resistant finish. With normal cleaning it will
last for many years.

WARNING

Under no circumstance should a soot
deterioration device be used in the
combustion chamber. These products known
as “soot busters” or “soot sticks” are
comprised of chemicals that burn at very high
temperatures which may exceed the
temperature rating of the combustion chamber
material.

Use of these products are detrimental to the
life expectancy of the combustion chamber
and will destroy the chamber. Refer to the
“Cleaning of Furnace” section for proper
cleaning methods.

CLEANING OF THE HEAT EXCHANGER

All of these units have four clean out plugs for easy
cleaning of the heat exchanger. They are accessible
from the front and back of these units by removing the
clean out access cover in the burner compartment and at
the back of unit. The furnace should be checked
annually by a qualified service technician.
