SAVE THESE INSTRUCTIONS FOR FUTURE REFERENCE
1. INTRODUCTION
Please read these instructions completely and carefully
before installing and operating the furnace.
The furnace must be installed and set up by a qualified
contractor
MODEL 80F
Model 80F is an oil-fired upflow forced air furnace, with
an output capacity range of 58,100 BTU/Hr. to 78,900
BTU/Hr. The 80F furnace equipped with a direct drive
blower may be installed in both horizontal positions.
MODEL 120F
Model 120F is an oil-fired upflow forced air furnace, with
an output capacity range of 87,700 BTU/Hr. to 113,400
BTU/Hr. The 120F furnace equipped with a direct drive
blower may be installed in both horizontal positions.
NOTE: Furnace models equipped with belt drive blowers
are not suitable for horizontal applications.
Both 80F & 120F Model furnaces are listed with the
Canadian Standards Association, (CSA), complies with
both Canadian and American (U.S.) standards for use
with No. 1 (Stove) and No. 2 (Furnace) Oil. Please refer
to the tables in the appendix for performance and
dimensional data.
All models are shipped assembled and pre-wired. The
furnace should be carefully inspected for damage when
being unpacked.
2. HEAT LOSS
To determine the correct furnace and firing rate for an
application, it is necessary to calculate the maximum
hourly heat loss of the building based on local design
conditions. In new construction, the heat loss should be
calculated on a room-by-room basis to enable proper
sizing of the trunk and branch ducts. In retrofit
applications, a building shell (overall) heat loss
calculation may be used.
In the United States, Manual J.
titled, "Load
Calculation" published by the Air Conditioning
Contractors of America, describes a suitable procedure
for calculating the maximum hourly heat loss.
In Canada, the maximum hourly heat loss may be
calculated in accordance with the procedures described
in the manuals of the Heating, Refrigeration and Air
Conditioning Institute of Canada (HRAI), or by other
method prescribed by authorities having jurisdiction that
are suitable for local conditions.
3. LOCATION OF UNIT
DO NOT USE GASOLINE, CRANK CASE OIL,
OR ANY OIL CONTAINING GASOLINE.
In the United States of America, the installation of the
furnace and related equipment shall be installed in
accordance with the regulations of NFPA No. 31,
Installation of Oil Burning Equipment
accordance with local codes.
In Canada, the installation of the furnace and related
equipment shall be installed in accordance with the
regulations of CAN/CSA - B139, Installation Code For
Oil Burning Equipment, as well as in accordance with
local codes.
When installation or application questions arise,
regulations prescribed in the National Codes and Local
Regulations take precedence over the general
instructions provided with this installation manual. When
in doubt, please consult your local authorities.
, as well as in
The furnace should be located such that the flue
connection to the chimney is short, direct and consists of
as few elbows as possible. When possible, the unit
should be centralized with respect to the supply and
return air duct work. A central location minimizes the
trunk duct sizing. All models may be installed on
combustible floors.

UP-FLOW INSTALLATION
Both furnaces models have been assembled for
installation in the up-flow position. Maintain all clearances
to combustibles as outlined in Table 1. Suggestion; as a
measure to prevent fuel oil from accumulating in
locations other than the fire pot, as could be the case in
the event of nozzle drip, install the furnace with an
approximate 2 degree slope from the oil burner casing
towards the fire pot. Use shims made of noncombustible
material.
Heat
Exchanger
Support
Screw
In the upflow position, the heat exchanger support screw
shown in picture may be removed. This may be
preferable if the furnace rear panel will be inaccessible
after installation. The screw must be removed if the heat
exchanger must be removed from the cabinet. Do not
remove this screw if installing furnace in a horizontal
position.
HORIZONTAL INSTALLATION
The furnaces are assembled and shipped ready for
installation in the up-flow position. The direct drive
equipped furnace may be installed in either of the
horizontal positions; warm air discharging left or warm
air-discharging right by following these steps:
1. Rotate the furnace 90° to the desired position.
2. Remove the three nut and washer sets fastening the
oil burner assembly to the furnace (Beckett Burner)
or loosen the burner mount Allen screw (Riello
burner). Rotate the oil burner assembly to be in the
normal upright position.
3. Re-align the oil burner assembly to the combustion
chamber (fire-pot), then secure into place with the
three nut and washer sets (Beckett burner) or by retightening the mounting Allen screw (Riello burner).
5
29733 R2 06/01/2003
NON-SUSPENDED INSTALLATION
Maintain clearances to combustibles as outlined in Table
1. Installation on a combustible floor requires a clearance
of 1 inch. This can be done by using a noncombustible
material such as one-inch thick channel iron or similar
material. The furnace must be supported in such a way
as to not allow twisting or sagging of the cabinet.
Suggestion; as a measure to prevent fuel oil from
accumulating in locations other than the fire pot, as could
be the case in the event of nozzle drip, install the furnace
with an approximate 2 degree slope from the oil burner
casing towards the fire pot. Use shims made of
noncombustible material.
SUSPENDED INSTALLATION
Refer to Figure 1. Maintain clearances to combustibles
as outlined in Table 1. The furnace may be suspended by
field fabricating a cradle of angle iron and threaded rod.
Secure the furnace with 2 inch minimum slotted angle or
equivalent, as shown in Figure 1. The furnace must be
supported in such a way as to not allow twisting or
sagging of the cabinet. Position the supports so as to not
interfere with accessing the burner and blower
compartments. Suggestion; as a measure to prevent fuel
oil from accumulating in locations other than the fire pot,
as could be the case in the event of nozzle drip, install
the furnace with an approximate 2 degree slope from the
oil burner casing towards the fire pot.
4. AIR CONDITIONING APPLICATIONS
If the furnace is used in conjunction with air conditioning,
the furnace shall be installed in parallel with or upstream
from the evaporator coil to avoid condensation in the heat
exchanger. In a parallel installation, the dampers or air
controlling means must prevent chilled air from entering
the furnace. If the dampers are manually operated, there
must be a means of control to prevent the operation of
either system unless the dampers are in the full heat or
full cool position. The air heated by the furnace shall not
pass through a refrigeration unit unless the unit is
specifically approved for such service.
The blower speed must be checked and adjusted to
compensate for the pressure drop caused by the
evaporator coil. Refer to Appendix B for recommended
wiring and electrical connections of the air conditioning
controls.
5. COMBUSTION AIR
When a furnace is installed in the full basement of a
typical frame or brick house, infiltration is normally
adequate to provide air for combustion and draft
operation. If the furnace is installed in a closet or utility
room, two (2) ventilation openings must be provided
connecting to a well ventilated space (full basement,
living room or other room opening thereto, but not a
bedroom or bathroom). One opening shall be located 6"
from the top and bottom of the enclosure at the front of
the furnace. For furnaces located in buildings of
unusually tight construction, such as those with high
quality weather stripping, caulking, windows and doors, or
storm sashed windows, or where basement windows are
well sealed, a permanent opening communicating with a
well ventilated attic or with the outdoors shall be provided,
using a duct if necessary. Size all of the openings and
associated ductwork by the standards provided in the
latest Oil Installation Code editions; NFPA 31 in the
United States, CAN/CSA B139 in Canada. Take all fuel
burning appliances in the area into consideration when
calculating combustion and ventilation air requirements.
The Model CAS-2B-90E Furnace Boot manufactured by
Field Controls, Inc. may be used with the furnace to
obtain combustion air directly from outdoors. Use of this
device does not alter the need for ventilation air;
however, it does provide a good direct source of
combustion air and is connected directly to the oil burner.

29733 R2 06/01/2003
Figure 2: Common Chimney Problems
6. CHIMNEY VENTING
The chimney must be sized correctly and be in good
repair. If the chimney is oversized, there is a high risk of
the flue gases condensing resulting in damage to the
chimney and other venting parts. This problem may be
corrected by the use of an appropriately sized chimney
liner.
If the chimney serves the furnace only, the vent should
be sized at 4 inch minimum, 5 inch maximum. The table
below is based on dedicated venting. If the furnace is to
be co-vented with other appliances, refer to NFPA 31,
Standard for the Installation of Oil Burning Equipment
NFPA 211, Standard for Chimneys, Fireplaces, Vents,
and Solid Fuel-Burning Appliances or CAN/CSA B139,

IMPORTANT: The chimney must be capable of providing
sufficient draft at all times for the safe removal of the
products of combustion.
The chimney should be tested under “winter” conditions;
doors and windows closed, all other fossil fuel burning
appliances on, clothes dryer on, bathroom fans on, etc. If
the chimney cannot overcome the competition for air, it
will be necessary to access the reason for it, and take
corrective action. If the chimney is found to be sized
correctly and in good repair, it will probably be necessary
to re-evaluate the availability of combustion and
ventilation air, and take corrective action.
The flue pipe should be as short as possible with
horizontal pipes sloping upward toward the chimney at a
rate of one quarter inch to the foot. The flue pipe should
not be smaller in cross sectional area than the flue collar
on the furnace. The flue pipe should connect to the
chimney such that the flue pipe extends into, and
terminates flush with the inside surface of the chimney
liner. Seal the joint between the pipe and the lining. The
chimney outlet should be at least two feet above the
highest point of a peaked roof. All unused chimney
openings should be closed. Chimneys must conform to
local, provincial or state codes, or in the absence of local
regulations, to the requirements of the National Building
Code.
See Figure 2 and Table 3 for common chimney problems
and their remedies.
THE FURNACE MUST BE CONNECTED TO A FLUE
HAVING SUFFICIENT DRAFT AT ALL TIMES TO
ENSURE SAFE AND PROPER OPERATION OF THE
APPLIANCE.
The flue pipe must not be routed through concealed
space, because it must be visually checked for signs of
deterioration during the annual inspection and servicing.
The flue pipe must not pass through any floor or ceiling,
but may pass through a wall where suitable fire protection
provisions have been installed. Refer to the latest edition
of CAN/CSA B139 for rules governing the installation of
oil burning equipment. In the United States, refer to the
latest edition of NFPA 31 for regulations governing the
installation of oil burning equipment.
7. BAROMETRIC DAMPER CONTROL
This device is used in conjunction with conventional
chimney venting. This control (or draft regulator)
automatically maintains a constant negative pressure in
the furnace to obtain maximum efficiency. It ensures that
proper pressures are not exceeded. If the chimney does
not develop sufficient draft, the draft control cannot
function properly. The draft regulator, must be installed
within the same room or enclosure as the furnace, and
should not interfere with the combustion air supplied to
the burner. The control should be located a minimum of 3
flue pipe diameters from the furnace breeching and
8
29733 R2 06/01/2003
installed in accordance to the instructions supplied with
the regulator.
8. FURNACE CONTROLS
The furnace is controlled by either of two systems,
depending on the oil primary control and electronic fan
timer combination. System 1, used with Beckett burners,
includes the blower mounted Honeywell ST9103
LECTRONIC FAN TIMER (EFT) combined with the R7184
E
IL PRIMARY CONTROL. System 2, used with Riello
O
burners, includes the blower mounted Honeywell ST9103
LECTRONIC FAN TIMER (EFT) combined with a
E
transformer / burner relay mounted internally on the 40F3
burner housing to operate the oil burner.
Figure 4: ST9103 EFT
condition is detected, one or both limit switches will
interrupt power to the oil primary control, which will shut
of the oil burner. The circulating fan will continue to
operate. The high limit switches will automatically reset
when the furnace returns to a safe temperature.
Figure 3: R7184 Oil Primary
The furnace functions are controlled by either System 1
or System 2, and bi-metallic snap disc limit switches.
These groupings also provide control for add-on air
conditioning. The ST9103 EFT is located in a control box
mounted to the blower support rails.
The circulating fan is controlled by the ST9103 EFT. The
heat delay-on time is fixed, at 30 seconds. This provides
a delay between the start of the burner and the start of
the circulating fan to reduce the amount of ambient
unheated air flowing through the ductwork. The end of
the circulating fan cycle is also delayed to remove
residual heat from the furnace. There are four delay-off
choices, 60, 90, 120 and 150 seconds, which are field
adjustable by manipulating the DIP switches on the
ST9103 EFT board.
The cooling delay-on and delay-off times are fixed at 30
seconds.
The furnace is protected against over-heating by fixed
high temperature limits. These controls are factory set
and are not field adjustable. If an over temperature
9. ELECTRICAL CONNECTIONS
The furnace is listed by the Canadian Standards
Association (CSA). It is factory wired and requires
minimal field wiring. In the United States, the wiring must
be in accordance with the National Fire Protection
Association NFPA-70, National Electrical Code, and
with local codes and regulations. In Canada, all field
wiring should conform to CAN/CSA C22.1 Canadian
Electrical Code, Part 1, and by local codes, where they
prevail.
The furnace should be wired to a separate and dedicated
circuit in the main electrical panel; however, accessory
equipment such as electronic air cleaners and humidifiers
may be included on the furnace circuit. Although a
suitably located circuit breaker can be used as a service
switch, a separate service switch is advisable. The
service switch is necessary if reaching the circuit breaker
involves becoming close to the furnace, or if the furnace
is located between the circuit breaker and the means of
entry to the furnace room. The furnace switch (service
switch) should be clearly marked, installed in an easily
accessible area between the furnace and furnace room
entry, and be located in such a manner to reduce the
likelihood that it would be mistaken as a light switch or
similar device.
9
29733 R2 06/01/2003
The power requirements for the HO-B Series models are:
120 VAC, 1 Æ, 60 Hz., 12A. 5-ton models: 120 VAC, 1 Æ,
60 Hz., 16A.
Accessories requiring 120 VAC power sources such as
electronic air cleaners and humidifier transformers may
be powered from the ST9103 EFT. Do not use the direct
drive motor connections as a power source, since there
is a high risk of damaging the accessories by exposure to
high voltage from the auto-generating windings of the
direct drive motor.
Thermostat wiring connections and air conditioning
contactor low voltage connections are shown in the wiring
diagrams. Some micro-electronic thermostats require
additional controls and wiring. Refer to the thermostat
manufacturer's instructions.
The thermostat should be located approximately 5 feet
above the floor, on an inside wall where there is good
natural air circulation, and where the thermostat will be
exposed to average room temperatures. Avoid locations
where the thermostat will be exposed to cold drafts, heat
from nearby lamps and appliances, exposure to sunlight,
heat from inside wall stacks, etc.
Normal heat anticipator setting: 0.1 A. For more precise
adjustment, the heat anticipator may be adjusted to the
amperage draw of the heating control circuit as
measured between the "R" and "W" terminals of the
thermostat. To reduce the risk of damaging the heat
anticipator, do not measure circuit without first removing
one of the two wires first. To determine the heating circuit
amperage draw:
1. Disconnect one of the “R” or “W” wires from the
thermostat terminal.
2. Connect an ammeter between the wire and the
thermostat terminal to which it was attached.
3. Note the amperage reading when the heating
contacts are closed. (System switch must be on
HEAT” if so equipped.
“
4. Re-connect the thermostat wire. If the thermostat is
serving a combination heating and air conditioning
system, pay particular attention to polarity.
5. When the thermostat is reconnected and replumbed, adjust the heat anticipator setting to match
the observed amperage reading.
10. HUMIDIFIER
A humidifier is an optional accessory available through
most heating supplies outlets. Installation should be
carried out in accordance with the humidifier
manufacturer's installation instructions. Water or water
droplets from the humidifier should not be allowed to
come into contact with the furnace heat exchanger.
Terminals (115 v) are provided on the ST9103 EFT
control. Do not use direct drive motor connections as a
source of power for 120 VAC humidifiers and humidifier
transformers.
11. OIL TANK
Oil storage tanks must be selected and installed in
compliance with applicable codes; in the United States,
NFPA 31, Standard for the Installation of Oil Burning
Equipment, Chapter 2. Observe all local codes and by-
laws. And in Canada, CAN/CSA-B139, Installation Code
for Oil Burning Equipment, Section 6
In general, the oil tank must be properly supported and
remain stable in both empty and full condition. The oil
tank must be fitted with vent and supply pipes to the
outdoors. Refer to the above-mentioned codes for sizing.
The vent pipe must be no less than 1¼ inches I.P.S., and
terminate with an appropriate vent cap in a location
where it will not be blocked. The fill pipe must be no less
than 2 inches I.P.S., and terminate with an appropriate
cap in a location where debris will not enter the fill pipe
during oil delivery.
If located indoors, the tank should normally be in the
lowest level, (cellar, basement, etc.). It must be equipped
with a shut-off valve at the tank outlet used for the oil
supply. The oil tank must be located as to not block the
furnace / room exit pathway. Observe all clearances
specified in the above-mentioned codes.
12. PIPING INSTALLATION
In the United States the installation must be in
accordance with the requirements of NFPA No. 31 and
local codes and regulations.
In Canada, the entire fuel system should be installed in
accordance with the requirements of CAN/CSA B139,
and local regulations. Use only approved fuel oil tanks
piping, fittings and oil filters.
Ensure that all fittings used in a copper oil line system are
high quality flare fittings. Do not use compression fittings
Do not use Teflon tape on any fittings.
Pressurized or gravity feed installations must not exceed
3 PSIG. Pressures greater than 10 PSIG may cause
damage to the shaft seal. If the height of the oil stored in
a tank above the oil burner exceeds 11½ feet, it may be
necessary to use a pressure-regulating device approved
for this purpose.

The furnaces may be installed with a one-pipe system
with gravity feed or lift. The maximum allowable lift on a
single line system is 8 feet. Lift should be measured from
the bottom (outlet) of the tank, to the inlet of the burner.
Sizing a single line system is complex because of the
difficulty estimating the pressure drop through each
fitting, bend and component in the line. In general, keep
single line systems short as possible. If the furnace is to
be installed in a suspended position, a two-pipe system
may be the better alternative. 2-stage oil pumps are not
available for either the Beckett or Riello burner. The
following chart shows the allowable line lengths
(horizontal + vertical) for single and two stage oil pumps.
All distances are in feet.
In retrofit applications, where an existing oil line system is
in place, a vacuum check will help determine the efficacy
of the existing oil line system The vacuum in a system
featuring a Beckett burner should not exceed 6” Hg. for a
single pipe system, nor 12” Hg. for a two-pipe system.
The vacuum in a system featuring a Riello burner should
not exceed 6” Hg. for a single pipe system, nor 11.44”
Hg. for a two-pipe system.

For additional information, see the installation information
sheet included in the documents envelope or affixed to
the oil burner.
NOTE: Both the Beckett and Riello oil burners require the
use of a bypass plug when converting from single-pipe to
two-pipe oil piping systems. See burner manufacturer’s
instructions.
NOTE: The Riello oil burner is manufactured with British
Parallel Thread pump ports. Adapters are supplied with
the oil burner to convert from British Parallel Thread to
NPT (National Pipe Thread). Direct connection of NPT
fittings to the Riello oil burner ports will result in damage
to the pump body. This also applies to pressure and
vacuum gauges. (See Riello manual)
13. OIL FILTER
All fuel systems should include an oil filter between the
fuel oil storage tank and the oil burner. For best results,
install the oil filter as close to the burner as possible.
When using an indoor oil tank, the oil filter may be
installed at the tank downstream from the shut-off valve.
If firing the furnace under the 0.65 gph rate, a 7 to 10
micron line filter should be installed as close to the oil
burner as possible.
14. OIL BURNER NOZZLES
The 80F Series furnace is certified for multiple firing
rates, ranging from 58,100 to 78,900 BTU/hr, while the
120F Series Furnace is certified for multiple firing rates of
87,000 113,400 BTU/hr. By changing the oil burner
nozzle within the specific Model Range, and temperature
rise, the furnace may be fired at an ideal rate for a wide
range of structures.

15. COMBUSTION CHAMBER
This furnace is equipped with an efficient cerafelt
combustion chamber. It is held in place by a retaining
bracket.

CHECK THE ALIGNMENT OF THE COMBUSTION
CHAMBER AND OIL BURNER BEFORE FIRING. IT
IS POSSIBLE FOR THE COMBUSTION CHAMBER
TO SHIFT IF SUBJECTED TO ROUGH HANDLING
DURING TRANSIT.
The cerafelt combustion chamber is quite soft initially.
After firing, it becomes very brittle. Be sure to do all
alignment and positioning adjustments before the first
firing.
The combustion chamber should be inspected for
damage or carbon build up whenever the oil burner is
removed for repairs or routine maintenance.
BEFORE OPERATING THE FURNACE CHECK

AND AMULET POSITION (RIELLO BURNER) AS
NECESSARY BEFORE FIRST FIRING.
build-up throughout the heat exchanger passages.
Excess combustion air causes a bright roaring fire and
high stack temperatures resulting in poor fuel efficiency.
PREPARATIONS:
Drill a ¼” test port in the venting, ideally at least 2 flue
pipe diameters away from the furnace breeching, if
venting horizontally from the furnace, or from the flue
pipe elbow if venting vertically before reaching the
furnace. (see Figures 5 and 6).
The test port will allow flue gas samples to be taken and
stack temperatures to be measured.
Before starting the burner, check the burner alignment
with the combustion chamber (fire pot), check that the
correct nozzle is tightened into place, and that the burner
electrodes are properly positioned. The Beckett burner
bulk air band is should be closed, and the air shutter
initial setting should be approximately 7.00.
Refer to Table A-2, page 18, for Riello oil burner air
damper and turbulator settings.

16. BURNER ELECTRODES
Correct positioning of the electrode tips with respect to
each other, to the fuel oil nozzle, and to the rest of the
burners is essential for smooth light ups and proper
operation.
Beckett Oil Burner:
The electrode tips should be adjusted to a gap of 5/32”,
1/16” ahead of the nozzle, 5/16” above the centerline of
the nozzle. The “Z” dimension (front edge of the burner
head to the front face of the nozzle is 1-1/8 inches.
Riello Oil Burner:
The electrode tips should be adjusted to a gap of 5/32”,
3/32” ahead of the nozzle, 13/64” above the centerline of
the nozzle.
The electrode porcelains should be free of cracks, the
electrode tips should be tapered and free of burrs, and
the contact rods must be clean and be in firm contact
with the ignition transformer contact springs. The
electrodes must not come into contact with the burner
head.
17. OIL BURNER SET UP
Note A: Locate hole at least 6 inches on the furnace side
of the draft control.
Note B: Ideally, hole should be at least 12 inches from
breeching or elbow.
The burner air supply is adjusted to maintain the fuel to
air ratio to obtain ideal combustion conditions. A lack of
air causes "soft" and "sooty" flames, resulting in soot
