7PN 28141 REV. K [10/30/2018]
9. Barometric Damper Control
Barometric damper control, also known as draft regulator,
is used on conventional chimney venting only. Control
automatically maintains constant negative pressure.
Ensures proper pressures are not exceeded. If chimney
does not develop sucient draft, draft control does not
function properly.
• Install draft regulator in same room or enclosure as
furnace. Draft regulator should not interfere with
combustion air supplied to the burner.
• Locate control near furnace ue outlet.
• Install per instructions supplied with regulator.
• Set over re draft, measured at oil burner mounting
plate over-re draft access port, to -0.02 in. w.c. See
Figure 2 page 6.
10. Optional Side Wall Venting

Refer to Appendix A, Table A2.
11a. Models with Electronic Fan Timer Control
and Snap-Disc Limit Control (See Figure 3)
Electronic Fan Timer integrates control of burner and
circulator fan operations. Control is central wiring point for
most of furnace electrical components.
• United Technologies 1158-120 has an adjustable
fan on time set by selecting dipswitch combination
displayed in Chart 1. Fan on delay can be set at 30,
60, 90 or 120 seconds. Provides a delay between
burner ignition and blower start-up to eliminate
excessive ow of cold air when blower comes on.
• United Technologies 1158-120 has an adjustable fan
o time of 2, 3, 4 or 6 minutes as displayed in Chart
1. Fan o delay time starts when burner motor is de-
energized at end of call for heat. Blower shutdown
is delayed to remove any residual heat from heat
exchanger.
• Electronic fan timer board works in conjunction with
snap disc limit controls, performing a safety function,
and breaks power to oil burner primary control,
shutting o burner if furnace over-heats.
• Limit control is thermally operated and automatically
resets. Limit control is factory installed, pre-set and
is not adjustable.
• If limit control opens with United Technologies
1158-120 electronic fan control, circulating fan will
energize. When limit closes, fan o timer begins.
At the end of fan o time cycle burner is energized,
initiating normal burner cycle.

11b. Models with Mechanical Fan And Limit
Control
Furnace equipped with White Rodgers 5D51 fan and limit
control. Temperature sensitive fan switch is actuated by a
helical bi-metal sensing element enclosed in a metal guard,
and controls the circulating air blower. This provides a delay
between burner ignition and blower start up to eliminate
excessive ow of cold air when blower comes on.
Blower shutdown is also delayed to remove any residual
heat from heat exchanger and improve annual eciency
of the furnace. Fan on settings of 110º F to 130º F (43º C
to 55º C) and fan o settings of 90º F to 100º F (32º C to
37ºC) will usually be satisfactory.
Limit switch performs safety function and breaks power
to oil burner primary control, which shuts o the burner if
furnace over-heats. Limit control is thermally operated and
automatically resets.
Limit control is factory installed, pre-set. Limit control
incorporates a limit stop which prevents the limit switch
from being set above the factory setting. Do not tamper
with or attempt to adjust limit stop. The limit control should
be set at or below the factory setting. DO NOT SET LIMIT
CONTROL ABOVE FACTORY SETTINGS.
Model Factory Limit Control Setting

1 HP Belt Drive 20
• Accessories requiring 120 VAC power sources such
as electronic air cleaners and humidier transformers
may be powered from furnace circuit, or from
electronic fan timer board where provisions have
been made for such connections, but should have
their own controls.
• Do not use direct drive motor connections as a power
source, there is risk of damaging accessories.
• Thermostat wiring connections are shown in wiring
diagrams in Appendix B. Some micro-electronic
thermostats require additional controls and wiring.
Refer to thermostat manufacturer's instructions.
• Locate thermostat approximately 5 feet above oor,
on inside wall, and where thermostat is exposed to
average room temperatures. Avoid locations where
thermostat is exposed to cold drafts, heat from
nearby lamps and appliances, exposure to sunlight,
heat from inside wall stacks, etc.
• Adjust thermostat heat anticipator to amperage
draw of heating control circuit as measured at "R"
and "W" terminals of thermostat. Do not measure
current with thermostat connected to the circuit.
Measure amperage by connecting ammeter between
two wires which connect to thermostat "R" and "W"
terminals.

9PN 28141 REV. K [10/30/2018]
13. Humidier
• Humidier is optional accessory available through
most heating supplies outlets.
• Follow humidier manufacturer's installation
instructions
• Protect furnace heat exchanger from water or water
droplets from humidier.
• Do not use direct drive motor connections as source
of power for 120 VAC humidiers and humidier
transformers.
14. Piping Installation
• Install fuel system in accordance with requirements
of CAN/CSA B-139, and local regulations.
• United States installation shall conform to NFPA No.
31 and local codes and authorities.
• Use only approved fuel oil tanks, piping, ttings and
oil lter.
• Install oil lter as close to burner as possible.
• Refer to instructions and illustrations in oil burner and
oil pump instructions shipped with the furnace.
15. Oil Filter
Install oil lter between fuel oil storage tank and oil burner.
When using oil burner nozzle smaller than 0.65 U.S.
Gallons Per Hour, install additional 7 to 10 micron lter as
close as possible to oil burner.
16. Oil Burner Nozzles
Furnaces are certied for multiple ring rates. Furnace
may be red at ideal rate for wide range of structures by
manipulating oil burner, nozzle, ame retention head, and
temperature rise. Refer to Table A-1 thru A-3, and furnace
rating plate to determine proper combinations.
17. Oil Burner Adjustment
• Adjust burner air supply to maintain fuel to air ratio
to obtain ideal combustion conditions.
• Lack of air causes "soft" and "sooty" ames, resulting
in soot build-up throughout heat exchanger passages.
• Excess combustion air causes bright roaring re and high
stack temperatures resulting in poor fuel eciency.
• Furnaces operate most eciently with No. 1 smoke
spot on Bacharach Scale. Dust will eventually build
up on air moving components of oil burner assembly
resulting in decreased air supply with potential soot
build up in ue gas passageways of heat exchanger.
Soot behaves as insulator and impairs good heat
transfer. Stack temperature increases, and eciency
decreases. To avoid this problem, adjust the air
supply to provide no more than trace smoke spot on
Bacharach Scale.
• See Venting Instructions included in Vent Kits for set-
up details for sidewall vented furnaces.
19. Burner Primary (Safety) Control
Furnace is equipped with primary combustion control, also
referred to as burner relay or burner protector relay, which
uses a cad cell located in burner housing, to monitor and
control combustion.
Dust or combustion residuals can build up on lens of
cad cell impairing its response to ame. Check cad cell
for cleanliness and proper alignment if primary control
frequently shuts down combustion.
20. Combustion Chamber
Furnace is equipped with cerafelt combustion chamber, held
in place by a retaining bracket.
Check the alignment of the combustion chamber
and oil burner before ring. It is possible for the
combustion chamber to shift if subjected to rough
handling during transit.
Inspect combustion chamber for damage or carbon build
up whenever oil burner is removed for repairs or routine
maintenance.
NOTICE
Set up sidewall vented models to deliver zero (0)
smoke.
NOTICE
Before operating furnace check burner alignment
with combustion chamber. End cone of air tube must
be centred to accommodating ring of combustion
chamber. Adjust as necessary.
18. Burner Electrodes
Correct positioning of electrode tips with respect to each
other, fuel oil nozzle, and burners is essential for smooth
light ups and proper operation.
Refer to oil burner instructions provided with furnace and
Appendix A Section A.2 for electrode specications.
NOTICE
Do not tamper with furnace controls they are
sensitive. If problems persist, call your service
contractor.

10 PN 28141 REV. K [10/30/2018]
Belt Drive Blower Systems
WARNING
Improper installation could result in death or serious
injury. Belt drive components operate at high speeds
and may snag loose clothing resulting in injury or
death. Have a trained service professional preform
the following instructions. Failure to follow these
instructions could result in death or serious injury.
!
Belt drive blower systems can be modied for speed and
air delivery by adjusting variable speed motor pulley and
changing blower pulley.
• Adjust variable speed motor pulley by loosening 5/32
allen set screw in outer sheave. Turn outer sheave
clockwise to increase blower speed, counter clockwise
to reduce speed.
• Verify setscrew is tightened at one of the at spots,
failure to do so will convert the variable speed pulley
to a xed speed pulley by ruining the threads.
• Modify blower speed by changing the blower pulley.
Smaller blower pulley will cause the blower to turn
faster. Large pulley reduces blower speed.
• Large increases in the blower speed may increase
power requirements.
• Check amperage draw of the blower motor after
making changes. If amperage draw is greater than
the value listed on the motor rating plate, replace
with motor of higher horsepower.
• Deection of 3/4 of an inch to 1 inch fan belt tension
is necessary. Less deection places a strain on the
blower bearings and increases start up amperage
draw.
• More deection allows excess slippage and causes
premature motor pulley wear.
• Automotive belt dressings are not recommended.
• Bar soap will work as belt dressing to reduce belt
squeaks, etc. If using soap apply to the sides of belt
only.
If operating belt drive blower at speeds above 1100
RPM, replace sintered bronze blower bearings with roller
bearings.
Blower assembly in BCL (170-2/190/200/225) models with
1 HP blower is equipped with roller bearings.
21. Circulating Air Blower
• BCL-S and BFL furnace models may be equipped with
either direct drive or belt drive blower systems.
• BCL high capacity furnace models are equipped with
belt drive blower systems.
Direct Drive Blower Systems
• Direct drive blower speed adjustments are not
normally required in properly sized extended plenum
duct systems. Motor RPM and air CFM delivery will
vary automatically to accommodate conditions within
usual range of external static pressures typical of
residential duct systems.
• Under-sized duct systems may require higher blower
speed to obtain system temperature rise.
• Some older duct systems were not designed to provide
static pressure. They typically feature special reducing
ttings at each branch run and lack block ends on the
trunk ducts. These systems may require modication
to provide some resistance to the airow to prevent
over-amping of direct drive blower motor. Selecting a
lower blower speed may correct this problem.
• Direct drive blower speeds are adjusted by changing
"hot" wires to motor winding connections. Refer to
wiring diagrams in Appendix B or wiring diagram label
axed to furnace.
• Do not move neutral wire (normally white wire)
to adjust blower speed.
• Single blower speed for both heating and cooling
modes may be used. Use a "piggy-back connector"
accommodating both wires on a single motor tap.
• It is also acceptable to connect selected motor speed
with a pigtail joined to both heating and cooling speed
wires with a wire nut.
• Safety precaution against accidental disconnection of
wires by vibration, secure wire nut and wires with few
wraps of electricians tape.
• Do not connect power leads between motor
speeds. Always connect neutral wire to motor's
designated neutral terminal.
• If joining blower speed wiring is done in furnace
junction box, tape o both ends of unused wire.
• Do not use blower speed wires as source of
power to accessories as electronic air cleaners
and humidier transformers. Unused motor
taps auto-generate suciently high voltages to
damage accessory equipment.
WARNING
Fire, burn, asphyxiation hazard. Do not start the
burner unless blower access door is secured in
place. Failure to follow these instructions could
result in death or serious injury.
!

11 PN 28141 REV. K [10/30/2018]
22. Maintenance And Service
Routine Maintenance By Home Owner
• Arrange for professional servicing of furnace by the
service or installation contractor annually.
• Homeowner is to maintain air lter or lters. A dirty
lter can cause furnace to over-heat, fail to maintain
indoor temperature during cold weather, increase fuel
consumption and cause component failure.
• Inspect, clean or replace lter monthly.
• Furnace is supplied with semi-permanent type lter.
If lter is damaged, replace with lters of same size
and type.
• During monthly lter inspection, inspect general
condition of furnace. Watch for signs of oil leaks in
vicinity of oil burner, soot forming on any external
part of furnace, soot forming around joints in vent
pipe, etc. If any of these conditions are present,
please advise your service or installation contractor.
Annual Service By Contractor
NOTICE
Combustion chamber (repot) is fragile. Use care
when inspecting and cleaning this area
• Inspect heat exchanger periodically and clean if
necessary.
WARNING
Electrical shock hazard. Turn OFF electrical
power supply at service panel before service or
maintenance Failure to do so could result in death or
serious injury.
!
• If cleaning is necessary, shut o oil supply, shut o
power to the furnace and remove burner.
• Use sti brush with wire handle, brush o scale and
soot from inside drum and ue pipe.
• Clean radiator, remove clean-out cap screws.
Remove caps carefully to avoid tearing gaskets.
• Wire brush can be used to loosen dirt and debris
on the inside surfaces of radiator. Clean out all
accumulated dirt, soot and debris with a wire handled
brush and an industrial vacuum cleaner.
• Before replacing clean-out caps, inspect gaskets. If
gaskets are broken, remove remnants and replace
with new gaskets.
• Blower motor is factory oiled and permanently
sealed. Do not lubricate. Excess oil causes
premature electric motor failure.
• Inspect blower fan. Clean if necessary.
• Oil Burner Maintenance: Follow oil burner
manufacturer instructions.
• Change oil burner nozzle and oil lter annually.
• Clean and inspect venting system for signs of
deterioration. Replace pitted or perforated vent pipe
and ttings.
• Barometric damper should open and close freely.
• Check electrical connections to ensure tight
connections. Safety controls such as the high limit
controls should be tested for functionality.
• Check fan control to ensure fan on and o delay
function continues to start and stop blower fan at
optimal settings.
WARNING
Electrical shock hazard. Turn OFF electrical power
supply at service panel before opening blower
access door. Failure to do so could result in death or
serious injury.

A.2 Burner Electrodes
Adjustment of electrode tips with respect to each other,
nozzle, burner head is very important to ensure smooth
start-ups and to permit ecient combustion.
Beckett AF and AFII Burners
• Electrode gap: 5/32 inch.
• Distance above horizontal center-line: 5/16 inch.
Older instruction sheets specify 7/16 inch. Current
specication is 5/16 inch.
• Distance ahead of nozzle: 1/16 inch.
• “Z” dimension, distance from front of end cone
(head) to face of nozzle should be 1-1/8 inches. If
ceramic head is used, distance from end cone to
nozzle face is increased to 1-3/8 inches.
Beckett NX Burners
• Electrode gap: 5/32 inch.
• Distance above horizontal center-line: 1/4 inch.
• Distance ahead of nozzle: 3/32 inch.
• Check/adjust zero calibration per Beckett NX Oil
Burner Manual supplied with furnace.
Riello 40F Burners
• Electrode gap: 5/32 inch.
• Distance above horizontal center-line: 13/64 inch.
• Distance ahead of nozzle: 5/64 to 7/64 inch.
A.3 Start Up
Use following instructions to set the burner:
1. Shut o electrical power to the furnace.
2. Install oil pressure gauge to pressure port on oil pump.
(Refer to oil pump specication sheet included with
burner instructions).
3. Restore electrical power to furnace.
4. Start furnace and bleed all air from fuel oil lines.
5. Close purge valve and re the unit.
6. Allow furnace to warm up to normal operating
temperatures. During this time, set pump pressure in
accordance with data provided in Appendix A, Table A-1
thru A-3.
7. Chimney vented units - Drill 1/4" test port in
venting between furnace ue outlet and draft regulator
(barometric damper) to take smoke readings.
8. Sidewall vented units - Do not drill. Use test port
in the supplied appliance connector to take smoke
readings.
9. When furnace has reached "steady state" (after
approximately 10 minutes). Set combustion air damper
to get TRACE of smoke for chimney vented units and
ZERO smoke for sidewall vented units.
10. Check system temperature rise. Temperature rise is the
dierence between return air temperature measured at
a point near return air inlet, and supply air temperature
measured near furnace outlet.
System temperature rise is listed on furnace rating
plate. If temperature rise is too high, airow must
be increased. If temperature rise is too low, slow fan
down.
11. After air adjustments have been completed, recheck
the over re draft at test port on burner mounting plate
shown in Figure 2. Over re draft should be adjusted to
-0.02 inches w.c.
12. Turn burner o. Observe duct thermometer in supply
air stream, note temperature blower fan stops. Fan on
delay and fan o delay adjustments can be made by
moving FAN ON and FAN OFF settings on fan and limit
control or by adjusting dipswitch settings on fan timer
board as applicable.
13. Check operation of limit switch.
A. Shut o power to furnace.
B. Temporarily remove neutral wire from blower
motor.
C. Restore electrical power to furnace.
D. Set thermostat above room temperature.
E. After three or four minutes of burner operation,
limit control should turn burner o.
F. When limit function test is complete, shut o
electrical power to furnace, replace neutral wire to
blower motor. Restore power.
G. Blower fan will start up immediately. Once
temperature has dropped and limit control has
reset, fan will operate until fan o temperature (fan
and limit control) or fan o time delay (fan timer
board) is reached.
H. Oil burner will resume operation and continue until
thermostat is satised.
I. Restore thermostat setting to comfortable
temperature.
APPENDIX A - CHECK OUT AND ADJUSTMENTS
