1. EZ-1/2/3 Application Information
Conversion burners
General information — conversion burners
Carlin EZ burners are shipped for general distribution, with fuel
units set for 100 psig. Burners are usually shipped assembled, with
a universal slip-on ange. Air tubes and housings will be installed
or shipped in separate boxes for eld assembly.
Before installing the burner, follow guidelines in this manual to
ensure you are using the correct nozzle, head-positioning bar and
air tube length.
Oil nozzle selection — conversion burners
If oil nozzle selection information for the application is not avail-
able from appliance documents, you can use Table 1, page 4, for
an initial nozzle selection for the application. Specic applications
may require testing more than one nozzle to obtain both clean
combustion and a good match of ame shape to the com-
bustion chamber.
OEM burners
General information — OEM burners
EZ burners manufactured for heating appliance manufacturers
(OEM’s) are generally identical to conversion burners (distributed
through supply houses) with one or more of the following differ-
ences:
• Burners may be fully assembled, with a welded ange set at
the proper insertion depth and pitch for the appliance.
• Burners may be installed on the appliance or shipped in a
separate carton.
• Burner nozzles may be installed in the burner, bagged or tied
onto the burner chassis, or located in the appliance packaging.
• Head positioning bars may be installed or bagged to the burner
chassis. Up to seven bars may be supplied. Use the bar with
a range that includes the nozzle size used.
EZ burners with the “-HP” sufx are only supplied through the heat-
ing appliance manufacturer (OEM) market. These burners differ
from standard models as follows:
• Fuel unit pressure is factory-set between 130 and 150 psig.
Check heating appliance manufacturer’s specications for the
correct pressure setting.
• The air band scale is calibrated for the fuel unit pressure. Set
the air band to match the nozzle size installed. See page 11 in
this manual for further information.
Installing OEM burners
• Burner anges are welded to the air tube to ensure the correct
pitch. Do not attempt to adjust the pitch using the air tube lock-
ing screws.
Oil nozzle selection — OEM burners
• Use only the nozzle speciced in the heating appliance manu-
facturer’s manual or burner supplement.

1. In general, all the nozzles shown above will burn well. However, in short combustion chambers, solid nozzles are not recommended because the ame may impinge
on the back wall.
2. If the nozzle selected for a retrot application results in a smoky re, you can sometimes determine the best nozzle to use by observing the ame. To do this, slowly
cover the air band slots with your ngers while the burner is ring. The ame will begin to smoke in the area where there is more fuel than air. If the smoke begins on
the outer edges, try a narrower or more solid nozzle spray pattern. If the ame begins to smoke at the tips, try a wider or more hollow nozzle spray pattern.
3. For a packaged appliance application on which the burner has been tested, use the nozzle given in the appliance manufacturer’s instructions or supplement for the
best results.

2. Prepare Site • Assemble Burner • Mount Burner
Inspect/repair/replace vent system
Do not install this burner unless you have veried
the entire vent system and the appliance are in good
condition and comply with all applicable codes. And ...
The vent and chimney must be sized and constructed
in accordance with all applicable codes.
Do not install or use an existing manual damper in the
breeching (vent connector) or chimney.
Do not connect the appliance vent connector to a
chimney or vent serving a replace, incinerator or
solid-fuel-burning apparatus.
In a cold climate, do not vent into a masonry chimney
that has one or more sides exposed to the outside.
Install a listed stainless steel liner to vent the ue
products.
A defective vent system could result in severe personal
injury, death or substantial property damage.
Prepare vent/chimney
• Secure all metal vent joints with screws, following the vent
manufacturer’s instructions. Seal all joints in the vent system
and chimney. Repair masonry chimney lining and repair all
mortar joints as needed.
• Install a barometric draft regulator in the vent piping if specied
in the appliance manual. (The damper must be located in the
same space as the appliance.)
• Provide support for the vent piping. Do not rest the weight of
any of the vent piping on the appliance ue outlet.
Combustion/ventilation air openings
Even if combustion air is piped to an (optional) burner
air intake adapter, the boiler room must still have the
minimum air openings listed in Table 2 and described
in the following paragraphs. This is to provide needed
ventilation to keep the burner and appliance cool and to
avoid the boiler room developing negative pressure.
The combustion air openings MUST be sized based
on the total input of all appliances in the room.
Check appliance manual and applicable codes for required sizing/
design/placement of combustion/ventilation air openings. You can
use the following general guidelines, taken from NFPA 31, provided
they meet all local requirements.
Louvers/screens
• Air opening sizes are always given in free area. This means
after deduction for louver obstruction. If you can’t nd the louver
reduction for the grilles used, assume free area is 20% of total
for wood louvers, or 60% of total for metal louvers.
• Screens can be no ner than ¼-inch mesh, and must be ac-
cessible for cleaning.
Residential installations
Unconned spaces (at least 7,000 cubic feet per GPH)
• An unconned space means a room with at least 7,000 cubic
feet volume for each GPH input (or 50 cubic feet per MBH) of
all appliances in the room. Example: For each 1 GPH oil input,
Table 2 Minimum combustion/ventilation air openings
the room must have 7,000 cubic feet (875 square feet with an
8-foot ceiling height.)
• Open basements and crawl spaces are usually large enough,
and will generally allow enough air inltration so special provi-
sions will seldom be required.
• If the building is tightly constructed, you will have to provide
outside air openings into the building. The total free area of the
openings must be at least 1 square inch per 5,000 Btuh (28
square inches per GPH) of all appliances in the space.
• See Table 2 for summary.
Air openings to conned spaces
(less than 7,000 cubic feet per GPH)
• Air taken from inside building only —
• Provide two openings — one near oor, the other near ceiling.
Provide free area of 140 square inches per GPH input. If build-
ing is tightly constructed, provide air opening(s) into building
providing 30 square inches per GPH as well.
• Air taken from outside —
• Direct through outside wall or vertical ducts: Provide two
openings — one near oor, the other near ceiling. Provide
free area of 35 square inches per GPH input.
• Through horizontal ducts: Provide two openings — one near
oor, the other near ceiling. Provide free area of 70 square
inches per GPH input.
• Ventilation air from inside/combustion air from outside
Size openings to interior to provide 140 square inches free area
per GPH input. Size outside air duct to provide 28 square
inches free area per GPH.
• See Table 2 for summary.

Model EZ-1/2/3 oil burners — Instruction manual
2. Prepare Site • Assemble Burner • Mount Burner (continued)
The burner may operate successfully under
momentary downdraft conditions, but sus-
tained downdraft is unsafe. This can occur
with an inadequate or incorrectly installed
chimney/vent. It can also occur in rooms/
buildings equipped with exhaust fans or un-
sealed return air ducts.
Always check operation of the burner under
all conditions to verify vent system operates
correctly.
Combustion/ventilation air openings:
Always provide combustion/ventilation air to
the appliance room sufcient to prevent any
negative pressure in the space — if neces-
sary, install new or additional air openings.
See instructions in this manual.
Piped combustion air applications:
Burners with piped combustion air require
the Field CAS-1 combustion air system. This
includes a vacuum relief valve that will cause
combustion air to be taken from the room if
the combustion air piping becomes blocked
or if any condition causes a vacuum in the
air piping. The equipment room must have
adequate air openings to provide combustion
air should this occur. See instructions in this
manual for combustion air openings.
Failure to correct downdraft or negative room
pressure operation could result in severe
personal injury, death or substantial property
damage.
Combustion/ventilation air checklist
:Verify that openings are unobstructed.
:Verify that appliance space and air source spaces are free of:
• Gasoline or other ammable liquids or vapors.
• Combustible materials.
• Air contaminants and chemicals, such as laundry products, paint,
thinner, varnish, etc.
:Conrm with the building owner that the area will be kept free of these
materials at all times and that air openings will be kept unobstructed.
Optional air intake systems
• Combustion air can be piped to the burner from outside if the burner
is tted with either a Burner Cover or P/N 97406 Air Intake System.
• You must use a Field Controls Model CAS-1 Combustion Air Supply
Duct Kit or equivalent, and install as per kit manufacturer’s instruc-
tions and any associated instructions in the Burner Cover or 97406
Air Intake System instructions.
Even if using an (optional) air intake system, make sure
the space provides enough ventilation to prevent overheat-
ing of the appliance, burner and controls. The equipment
room must have combustion air/ventilation openings sized
large enough to provide air for cooling the equipment and
for combustion when needed. Failure to comply can result
in severe personal injury, death or substantial property
damage.
Air piping
Follow all manufacturers’ instructions carefully when install-
ing the air intake duct assembly. Failure to carefully follow
all instructions can result in hazardous operating condi-
tions.
1. Install the optional air inlet adapter if the burner is tted with a Burner
Cover.
Air piping must be 4-inch diameter metal or PVC. Install a
4x3 reducer at the air adapter (if using a burner cover).
2. Connect air piping to the Field Controls Model CAS-1 Combustion Air
Supply Duct Kit and install as per Field Controls’ instructions.)
Maximum air piping length
1. USE ONLY 4-inch air piping.
2. DO NOT exceed 80 equivalent feet of air piping. NOTE: Install
vent piping as specied in appliance manufacturer’s instructions.
3. Reduce maximim length by 10 equivalent feet for each elbow in the
air piping.
4. Example: The air piping could consist of (3) elbows (equals 30 equiv-
alent feet) and 50 feet of straight piping; or (4) elbows (equals 40
equivalent feet) and 40 feet of straight piping.
Burner adjustments with optional Burner Cover
1. Follow the instructions in this manual for nal adjustments to the
burner using combustion test instruments.
2. Once combustion is initially set, re-install the cover and test again.
If necessary, remove the cover and readjust the burner. Repeat the
process until combustion is correct with the cover in place.
3. You must also measure air inlet temperature during start-up to prop-
erly the set combustion. Follow the instructions in this manual.
Burner adjustments with optional Air Intake System
1. Follow the instructions in this manual and in the Air Intake System
instructions for adjustments to the burner using combustion test
instruments.
2. You must also measure air inlet temperature during start-up to prop-
erly the set combustion. Follow the instructions in this manual.

2. Prepare Site • Assemble Burner • Mount Burner (continued)
Verify combustion chamber
General guidelines
• If retrotting the burner to an appliance, install the burner in ac-
cordance with the appliance instruction manual, when available.
If no specic application data is available from the appliance
manufacturer, apply the guidelines in Table 3 to check whether
the burner is likely to work acceptably in the application.
• Clean all appliance ues and heating surfaces thoroughly,
removing all soot and scale.
• Seal all joints and gaps using furnace cement to prevent excess
air inltration.
Minimum combustion chamber dimensions
• Illustrations A to C in Table 3 show different chamber congu-
rations.
• Do not attempt to re the burner in a chamber with dimensions
smaller than shown in Table 3 unless the application has been
Table 3 Burner retrot applications — guidelines and minimum dimensions for combustion chambers
Verify clearances
Verify that the burner/appliance will maintain all clearances from
combustible construction and clearances for service/maintenance
as required in the appliance manual and applicable codes.
Verify that the vent system components maintain all necessary
clearances to combustible construction, including the correct design
of thimbles and insulation where penetrating combustible walls.
specically tested and listed by the appliance manufacturer
and/or Carlin.
• Please notice the special requirements given in Table 3 notes.
Using chamber linings and lightweight chambers
• When using refractory liners or lightweight chambers, use
insulating-type refractory rated 2300°F minimum.
• You must install a target wall liner if ame length is close to the
length of the chamber.
• Use a oor liner when possible. The oor liner will improve ring
in most applications. Extend oor liner 3 to 4 inches up side wall.
• Target wall liners — Corbel the top of target wall liners 1½ to
2½ inches deep and extend at least 3 to 4 inches above the
center of the ame.
• Use pre-formed chamber liners when available.
• For ring rates below 0.75 GPH, it is best to apply in a refractory-
lined or stainless tube (designed for application) chamber.
Lining the oor and target wall of the chamber with lightweight
insulating refractory will accomplish the same.
• When conversion ring coal-red units, install a combustion
chamber in the ashpit area, or ll ashpit with sand up to 2 inches
above the “mud ring” of a boiler (ring through the door). Install
a lightweight refractory liner on the target wall as in Table 3,
Figure C. Make sure the minimum dimensions comply with
those listed.
A. Conversion ring coal-red units
1. Install a combustion chamber in the ashpit area, or ll
ashpit with sand up to 2 inches above the “mud ring”
of a boiler (ring through door).
2. When ring through door, install a lightweight refractory
“target” on the rear wall, as shown.
B. Conversion ring dry-base units
1. Applies to brick, refractory, precast and preformed
refractory ber chambers. Lightweight, insulating-type
materials are preferred because of their quick warm-up.
Use material rated at least 2300°F.
2. Dimensions in the table can be exceeded without much
effect for dry-base units.
C. Conversion ring wet-based units
1. Apply recommendations here to prevent ame from
impinging on surfaces or being cooled too much by the
cool walls of the heat exchanger. Do not exceed dimen-
sions of table more than 50% to avoid ame chilling.
2. Install a ceramic ber oor liner (extended 3 to 4 inches
up the side walls) and a ceramic ber rear target the
full width of the back wall as well. Corbel the top of
the target 1½" to 2½" deep and extend at least 3 to 4
inches above the center of the ame. Use preformed
chambers and/or target walls if available.
3. Set the fuel unit pressure for approximately 150 PSIG
and use a nozzle rated about 20% less than the ring
rate to compensate for the higher pressure. This will
improve atomization, making the ame more intense,
shorter and hotter. Use a head bar matched for the
nozzle size, but set the air band to match the ring rate.

Model EZ-1/2/3 oil burners — Instruction manual
Removing/installing head assembly
Use care when handling burner components after
the burner has been ring. Components can be
hot and could cause severe personal injury.
You will need to remove the combustion head assembly for
inspection of the assembly, replacement of the oil nozzle or
adjustment of electrodes.
Note: Do not have to remove access cover unless combus-
tion head has bafe.
To remove the assembly:
1. Loosen, and then rotate the two screw clamps securing
the ignitor in place. Swing the ignitor plate open.
2. Disconnect the nozzle line heater harness.
3. Unscrew the oil line tting and thumb nut at the burner
housing.
4. Pull the threaded end of the oil tube into the blower hous-
ing (Figure 5).
5. Rotate the assembly 180° so the electrodes are upside
down. This places the electrode insulators out of the way
for easy removal.
6. Remove the combustion head assembly, as shown in Fig-
ure 5, by pulling the assembly up and out of the housing.
7. Handle the assembly with care to avoid bending/mov-
ing the electrodes, or damaging the electrode ceramic
insulators.
8. Inspect the gasket on the bottom of the ignitor plate. The
gasket prevents air from escaping from the housing.
Replace the gasket if not in good condition.
9. Inspect the ignitor contact clips. Clean or replace if nec-
essary to ensure reliable contact with the electrodes.

3. Prepare Burner
Install nozzle/check electrodes
1. Loosen the clamp screw on the retention ring assembly
(see Figure 6). Slide the retention ring assembly off of
the nozzle adapter.
2. Install and tighten the nozzle shown in Table 1, page 4,
for retrot applications. Install the nozzle given in the
appliance manual when application information for the
EZ-1/2/3 oil burner is given.
3. Hold the nozzle adapter securely when removing or re-
placing the nozzle (Figure 7). Take care not to damage
the electrode insulators or to bend the electrodes in the
process.
Figure 6 Electrode placement, retention ring assembly and
nozzle adapter
Inspect the nozzle adapter before replacing
the nozzle. If the threads have been damaged
or shows score marks, replace the nozzle line/
adapter assembly.
4. Replace the retention ring assembly by slipping one of
the riveted arms through the gap between the electrode
tips. Align this arm straight up, with the ring clamp rmly
against the nozzle adapter shoulder. Then tighten the
clamping screw.
5. Check the electrode settings. Position the electrodes as
shown in Figure 6. These settings are critical in ensuring
a reliable ignition. Once the electrodes are set, check all
clamps to be sure they are securely tightened.

the air band until the pointers line up with the setting
indicated in the OEM Set-up Table or to a setting that
matches the nozzle size (for a retrot burner). The EZ-LF
uses an airband that indicates percentage of opening.
See gure 10.
2. NOTE: For high altitude installations above 2,000 feet,
increase the air supply setting 4% for each 1,000 feet
above 2,000 feet above sea level.
3. The burner is now adjusted to the approximate air band
setting for the nozzle size indicated. When you check
combustion with instruments during start-up or servicing,
you may have to adjust the air band slightly to achieve the
desired combustion readings. See “Adjust burner using
test instruments,” page 15.

Model EZ-1/2/3 oil burners — Instruction manual
3. Prepare Burner (continued)
Inspect/install fuel supply
Inspect the oil supply system. Ensure that the fuel
lines are correctly sized and installed and that the
fuel ow is unobstructed, the oil tank is clean and
only #1 or #2 heating oil are supplied. Failure to
supply a reliable oil ow could result in loss of heat
and potential severe equipment damage.
Nozzle line heater
• Oil burners often operate in spaces where temperatures tend
to be cool, typically 60°F or lower. Cool oil has higher viscos-
ity, which can affect atomization, ignition, combustion and fuel
consumption. The nozzle line heater avoids this problem by
heating the nozzle line oil to between 120°F and 130°F, result-
ing in smoother ignition and improved combustion.
General guidelines:
• When installing oil lines, use continuous runs of heavy-wall
copper tubing if possible.
• Check fuel unit (oil pump) data sheet for recommended line
sizing, lift limitations and maximum length.
• Check all connections and joints to ensure they are air-tight.
• Use are ttings. Do NOT use compression ttings.
• Never use pipe sealing tape. Fragments can break off and plug
fuel line components.
• Install a shut-off valve at the tank and one near the burner. (Use
fusible handle design valves when possible or when required
by codes.)
• Install a large capacity fuel lter (rated for 50 microns or less)
near the burner.
Fuel unit bypass plug
The fuel unit is shipped ready for a one-line oil system
(bypass plug is shipped loose). Install the bypass plug
only if connecting to a two-line oil system. Operating
with the plug in place on a one-line system will dam-
age the fuel unit and could lead to oil leakage and re
hazard.
If the fuel line or fuel supply is above burner, never
exceed 3 psig pressure at the fuel unit inlet. Install a
suitable OSV to reduce the pressure. Operating the
fuel unit with higher inlet pressure could result in fuel
unit seal damage, oil leakage and potential re hazard.
• The nozzle line heater needs power when the burner is in
standby (no call for heat from the appliance). Make sure the
nozzle line heater is powered directly from the 120 vac HOT line,
not through the appliance operating control circuit. The nozzle
line heater wiring should be shown on the wiring diagram sup-
plied with the appliance/burner unit.
• The nozzle line heater is supplied with an electrical disconnect
harness, allowing removal of the combustion head assembly
without disconnecting wires. Position the heater harness discon-
nect in the rear of the blower housing, above the blower access
cover. The wire leads to the disconnect route through the side
of the housing into the junction box.
When rst starting the burner, or after the service switch
has been off for some time, the heater requires about
15 minutes to bring the oil to operating temperature.
Figure 11 One-line fuel system
One-line fuel system requirements
See Figure 11. The standard burner fuel unit is a single-stage, 3450-
RPM oil pump. Apply this fuel unit only on one-line systems where
the fuel supply is on the same level with, or higher than, the burner.
This ensures oil ow by gravity. Also make sure the total lift does
not exceed 8 feet (height difference from bottom of oil tank to fuel
unit). For other conditions, you must provide a two-line fuel system.
You may also have to change the fuel unit to a two-stage type.

unit data sheet for any other fuel unit.
Perform checkout procedures
Verify before starting burner
Should overheating or an emergency occur, immedi-
ately:
• Shut off oil supply line valve.
• Under some circumstances power should remain
on for water pumps or blowers. Determine proper
response before attempting start-up.
• If burner fails ignition on several attempts, use burner
blower to purge appliance chamber before restart.

3. Prepare Burner (continued)
Two-line fuel system requirements
See Figure 12 and Table 4. Use Table 4 only for burners equipped
with Suntec fuel units. For burners using other fuel units, read the
fuel unit manufacturer’s data sheet to determine maximum lengths
and lifts.
The standard burner fuel unit is a single-stage, 3450-RPM oil pump.
Use this fuel unit only on two-line oil systems that do not exceed
the total tubing lengths allowed in Table 4 (for Suntec fule units
only). For longer systems (or where lift exceeds 10 feet), replace
the one-stage fuel unit with a two-stage unit.
Always size fuel lines using an oil ow rate based on the fuel unit
gearset capacity, not the burner ring rate. See fuel unit data sheet
for information.
Install the fuel unit bypass plug when connecting to a
two-line system. The plug is shipped in a bag attached
to the fuel unit, along with a fuel unit data sheet.

Model EZ-1/2/3 oil burners — Instruction manual
5. Adjustment and Verification
Perform combustion test
COMBUSTION MUST BE VERIFIED WITH THE
(OPTIONAL) BURNER COVER IN PLACE —
Remove the burner cover if installed. Set up and adjust the
burner using the following procedure. Replace the burner
cover, allow the burner/appliance to run at least 15 minutes,
then check combustion again. Readjust the burner is nec-
essary. The CO2 will increase when the cover is put on,
particularly if combustion air is piped to the burner.
If air is ducted to an (optional) air adapter, combustion must
be set based on the air inlet temperature. Air temperature
variations will change how much air enters the burner, so the
combustion must be set to anticipate the variations. Follow
the guidelines below.
Adjust burner using test instruments
1. Operate burner for 15 minutes before making nal adjustments using
test equipment.
2. Check for leaks in fuel piping.
Inspect fuel piping system for leaks. Repair any leaks to avoid
re hazard from oil leakage or combustion problems due to
air inltration into oil.
3. Inspect ame
• Look at ame through appliance combustion chamber observation
port. The ame should be well-dened and should not impinge on any
appliance surface. (If you make air or gas pressure changes later,
inspect the ame again.)
Do not attempt to conrm combustion simply by inspecting
the ame visually. You must use combustion test instruments.
Failure to properly verify/adjust combustion could allow unsafe
operation of the burner, resulting in severe personal injury,
death or substantial property damage.
4. Insert test probe into vent or appliance ue damper sample opening
to sample ue products.
Heating units designed for natural draft operation are normally
set for a slightly negative pressure, usually –0.01 to –0.02
inches w.c. draft at the combustion chamber test port. Ap-
pliances designed for forced draft (positive pressure in the
chamber) must be air-tight to prevent exltration of harmful
combustion products. Failure to properly set draft for the
appliance could result in severe personal injury or death.
5. Use combustion test equipment to verify that the burner is properly
set up for your installation. Appliances with positive pressure in the
chamber may require a wider air opening. See appliance instructions
for details. Verify/adjust settings by testing with instruments.
• With the EZ burner equipped with the correct positioning bar, oil
nozzle and initial air band setting, the ue products will usually
contain between 11½% and 12½% CO2 (5.9% and 3.8% O2) and
zero (Bacharach) smoke. (Based on air inlet temperature of 70°F
— see Table 5 for the proper values at other air temperatures for
burners with ducted combustion air.)
• Depending on length of air piping (when used) and on air tempera-
ture, CO2may change one per cent or more with the cover in place.
• Check smoke. It should be zero on the Bacharach scale.
• Set the appliance ue damper or barometric draft regulator so the
draft or pressure in the vent complies with the appliance manufac-
turer’s instructions.
Re-install (optional) burner cover and check combustion
again
1. Allow the burner to operate with the cover on for at least 15 minutes.
(Insert a temperature probe to measure incoming combustion air tem-
peature if combustion air is ducted to the burner.)
• Retest CO2(or O2) and smoke again. The values will change when
the cover is installed. Depending on length of air piping and on
air temperature, CO2may change one per cent or more with the
cover in place.
• Make sure the CO2(or O2) values are in the range given in Table 5
for the inlet air temperature measured. IF NOT, remove the cover
and adjust the air band more open to decrease CO2(increase O2)
or close the air band slightly to increase CO2(decrease O2).
• Tighten air band clamping screw.
All installations should be checked after one to two weeks of
operation to ensure the appliance/burner units are operating
correctly.

Model EZ-1/2/3 oil burners — Instruction manual
Perform the following
This burner must be started and serviced at least annually
by a qualied service technician. Failure to properly maintain
and service the burner could result in severe personal injury,
death or substantial property damage.
• Discuss burner/appliance operation with user to determine any problems
that may have occurred during the previous season and to verify user
is aware of proper operation and care of the burner/appliance.
• Review proper operation of the appliance/burner unit with the user.
• Turn off power to appliance.
• Remove combustion head assembly to clean and adjust if necessary.
(See procedure on page 10.)
• If the inside surface of the air tube and/or retention ring need to be
cleaned, clean them with a vacuum cleaner with brush attachment
while the combustion head assembly is out of the burner.
• Replace the oil nozzle with the correct size.
• Inspect and adjust the ignition electrodes and insulators per instructions
on pages 10 and 11 of this manual. Replace if proper spacing cannot
be achieved or if components are damaged.
• Close the housing cover plate and secure in place.
• Inspect the fuel line oil lter. Replace if necessary.
Oil line lters — Use a non-bypassing lter to prevent nozzle
plugging caused by poor oil ltration. Non-bypassing lters
prevent small foreign particles from bypassing the lter, a
common problem with ber element type lters. Another
problem of some lters is the ber from lter element tears
can break away and plug the nozzle or fuel unit.
• Perform the complete checkout procedures of pages 10 to 13, including
system inspection and checks.
• Inform the user of any problems found.
Verify burner/appliance operation
Check burner/appliance/controls operation
• Test operating and limit controls on appliance as specied in appliance
instructions.
• Check operation of the primary control by forcing lockout to occur.
For primary controls that enter latch-up after multiple lockouts, force
latch-up to occur as well. Reset primary control per control data sheet
instructions after each test.
• Start and stop the burner several times, allowing the primary control to
sequence through normal operation. Verify correct operation of burner
and primary control throughout.
Verify vent system operation
• Verify vent is operating correctly and ue products are properly ex-
hausted from building. If the building contains any exhaust fans or
conditions that could affect vent performance, check burner/appliance/
vent operation with exhaust fans (or other conditions) operating.
Combustion/ventilation air
• Verify combustion/ventilation air openings are not/will not be obstructed.
• Verify air opening louvers are full open.
• If louvers are motor-operated, verify motor and end switch are inter-
locked with appliance/burner wiring to prevent operation of the burner
if the air louvers are not fully opened.
Prepare burner for normal operation
• Cycle burner off with appliance controls.
• Turn off power to the appliance.
• Seal the appliance ue damper test opening.
• Verify all components and wires are in place and burner is ready for
operation.
• Restore power to the appliance.
Train the user
• Train the user to operate the burner and appliance under normal
conditions.
• Explain procedure to shut down burner/appliance when required.
• Review rear cover of this manual (and the appliance manual) with
the user.
• Verify the user is aware of all procedures specied in the manuals.
• Verify user will not store or use combustible liquids or materials or
contaminants in the vicinity of the burner/appliance.

8. Maintenance Procedures
Maintenance/service procedures
Turn off power to appliance when servicing burner. Failure
to comply could result in severe personal injury, death or
substantial property damage.
Cleaning blower wheel
1. The blower wheel accumulates dust and debris from normal operation.
You will need to clean the wheel blades periodically to prevent reduction
in airow.
• Inspect the blower wheel by removing the blower wheel access
cover.
• To remove the cover, open the ignitor plate and loosen the blower
wheel access cover screw about three turns.
• Inspect the blower wheel to see if it needs to be cleaned. Dirt and
lint on the wheel reduce air ow, and must be removed if the burner
is to operate correctly.
2. To clean blades, remove the two bolts securing the motor to blower
housing.
a. Slide the motor out and rotate to remove and access blower wheel.
b. Use a brush and vacuum to clean each blade and the blower hous-
ing interior.
c. Replace motor/wheel in blower housing and secure with the two
bolts.
d. Push wire slack back into junction box.
Replacing blower motor or wheel
1. If either the blower wheel or motor must be replaced, remove the two
bolts securing the motor to housing.
2. Disconnect the motor wires in the burner junction box.
3. Loosen the Allen screw securing the blower to the motor shaft and
remove the wheel.
4. When assembling the replacement assembly, slide the wheel onto the
motor shaft and use feeler gauges to set a space of 3/64 inch between
the blower wheel and the motor face.
5. Replace the motor/wheel assembly in the housing, wire the motor leads
and secure the motor with the two bolts.
Motor maintenance
• The Carlin PSC motor is constructed with permanently-lubricated bear-
ings, and requires no oiling. Should you replace the original motor with
another type of motor, occasional oiling may be required, depending
on motor design and manufacturer’s recommendations.
• Any time you replace a component or disassemble any part of the
burner for service/maintenance, perform a complete operational test
after reassembly to verify the burner operates correctly. Failure to verify
operation could result in severe personal injury, death or substantial
property damage.
Checking ignitor
Never test an ignitor by placing a screwdriver (or other me-
tallic object) across the high voltage clips. Check 40700 &
40900 ignitors only by observing spark at appliance ignition
electrodes, with fuel supply OFF. Using any other method
could cause ignitor damage and severe personal injury.
1. Checking 41000 ignitors only:
• Disconnect electrical power to burner.
• Remove hold down clips or screws. Lift ignitor mounting plate to
the full-open position. Set high voltage clips to a ½” to ¾” gap.
• Carefully energize ignitor and check for spark arcing at the high
voltage terminals. If spark jumps the gap, ignitor is good.
Ceramic ber materials
The appliance may contain ceramic ber and/or berglass
materials. Ceramic ber materials, such as chamber liners, may
contain carcinogenic particles (chrystobalites) after exposure
to heat. Airborne particles from berglass or ceramic ber
components have been listed as potentially carcinogenic by
the State of California. Take the following precautions when
removing, replacing and handling these items.
Avoid breathing dust and avoid contact with skin or eyes. Wear
long-sleeved, loose-tting clothing, gloves and eye protection.
Use a NIOSH N95 certied respirator. This respirator meets
requirements for protection from chrystobalites. Actual job
requirements or NIOSH regulations may require other or
additional protection. For information, refer to the NIOSH
website, http://www.cdc.gov/niosh/homepage.html.
Ceramic ber removal: To prevent airborne dust, thoroughly
wet ceramic ber with water before handling. Place ceramic
ber materials in a plastic bag and seal to dispose.
Avoid blowing, tearing, sawing or spraying berglass or ce-
ramic ber materials. If such operations are necessary, wear
extra protection to prevent breathing dust.
Wash work clothes separately from other laundry. Rinse clothes
washer thoroughly afterwards to prevent contamination of
other clothing.
NIOSH First aid procedures:
Eye exposure — irrigate immediately
Breathing — fresh air.

For other than routine maintenance, con-
tact a qualied service company. Perform
the following as needed.
• Keep the area around the burner clear
and free from combustible vapors and
liquids.
• Do not obstruct the ow of combustion
and ventilating air.
• Most motors currently used on resi-
dential type burners use permanently-
lubricated bearings, and do not require
eld lubrication. Read the label on the
motor to determine oiling needs, if any.
Do not over-lubricate. This can cause
as much trouble as not lubricating at all.
Never attempt to use gasoline as
a fuel for this burner, as it is more
combustible and could result in
a serious explosion. Never at-
tempt to burn refuse or use any
fuel other than #1 or #2 heating
oil (ASTM D396).

User Care and Maintenance
Refer only to the information on
this page, intended for your use.
The remainder of this manual is
intended only for your service techni-
cian. Failure to comply could result
in severe personal injury, death or
substantial property damage.
Should overheating occur:
1. Shut off the oil supply to the burner.
2. DO NOT shut off the control switch to
the circulator or blower.
3. Contact your oil dealer or service
technician and the re department (if
needed).
The burner must be cleaned, tested and
adjusted annually by a qualied oil burner
service technician.
