Fire, Smoke & Asphyxiation
Hazard

Carefully inspect the chimney or exhaust vent

y

system.

Make sure it is properly sized and in good working

y

condition.

Follow the instructions supplied by the appliance

y

manufacturer.

The installation must strictly comply with all

y

applicable codes, authorities having jurisdiction and
the latest revision of the National Fire Protection
Association Standard NFPA 31 for the installation of
chimneys and vent sizing, (or CSA-B139 and CSA­B140 in Canada).

Regulation by these authorities take precedence

y

over the general instructions provided in this
installation manual.

The new designs of high effi ciency oil furnaces and
boilers in conjunction with fl ame retention oil burners
are more effi cient. One result of increased effi ciency is
lower fl ue gas temperatures. As fl ue gases rise in the
chimney, they will cool and condense when they reach
the dew point. The condensation will mix with the sulphur
in the fl ue gases creating sulphuric acid. The acid will
attack the chimney mortar, brick and clay liners causing
corrosion, deterioration and blockage of the chimney.

6

Section: Inspect/Prepare Installation Site

Eventually the blockage could prevent exhausting the
fl ue gases. Instead, the fl ue gases could vent out the
barometric damper into the living space.

Therefore, it is strongly recommended that an approved
insulated stainless steel liner be installed.

Combustion Air Supply Information

Adequate Combustion
and Ventilation Air Supply
Required

Failure to provide adequate air supply could
seriously affect the burner performance and result in
damage to the equipment, asphyxiation, explosion or
fi re hazards.

The burner cannot properly burn the fuel if it is not

y

supplied with a reliable combustion air source.

Follow the guidelines in the latest editions of the

y

NFPA 31 and CSA-B139 regarding providing
adequate air for combustion and ventilation.

the burner or provide a sealed enclosure for the burner
and supply it with its own combustion air supply.

Direct/Sidewall Venting Application

When sidewall venting appliances, carefully

○

follow appliance and power venter instructions for
installation and wiring.
AFII burners are equipped with a removable air

○

inlet to allow use of a 4” duct to supply outside air
for combustion. Do not exceed 50 equivalent feet.
Allow 6 feet for each elbow.

Remove the inlet cover.

1.

Insert 4” duct into the inlet ring.

2.

Fasten duct into place using at least 3 sheet

3.
metal screws evenly spaced around the inlet
ring. Refer to Figure 3.

Remove the barometric draft control unless it is

4.
in the same atmospheric pressure zone as the
inlet.

Figure 3. Outside Air Connection

Appliances located in confi ned spaces: All confi ned
spaces should have two (2) permanent openings; one
near the top of the enclosure and one near the bottom
of the enclosure. Each opening must have a free area
of not less than one (1) square inch per 1,000 BTU’s per
hour of the total input rating of all appliances within the
enclosure. The openings should have free access to the
building interior, which should have adequate infi ltration
from the outside.

Exhaust fans and other air-using devices: Size air
openings large enough to supply all air-using devices
in addition to the minimum size required for combustion
air. If there is any possibility of the equipment room
developing a negative pressure due to exhaust fans,
clothes dryers, etc., either pipe combustion air directly to

The air inlet elbow must be located above the snow
line and in such a way as to prevent leaves and/or
other debris from blocking the air fl ow. Such debris
will prevent proper operation of the burner. Refer to
local codes for proper location of inlet.

Installing the Oil Tank and Supply System

Oil Leak and Fire Hazard

Install the oil tank following applicable standards
in the U.S. by referring to the latest edition of NFPA
31 or CSA-B139 & CSA-B140 in Canada, and all
authorities having jurisdiction.

Do Not Use Tefl on Tape

Damage to the pump could cause impaired burner
operation, oil leakage and appliance soot-up.

Never use Tefl on tape on fuel oil fi ttings.

y

Tape fragments can lodge in fuel line components

y

and fuel unit, damaging the equipment and
preventing proper operation.

Use oil-resistant pipe sealant compounds.

y

For fuel line installation, continuous lengths of heavy
wall copper tubing are recommended. Always use fl are
fi ttings. Never use compression fi ttings.

Note: to determine the proper fuel line size, refer to the
fuel pump manufacturer’s instructions provided with
the burner. Refer to Figure 4 or Figure 5 for typical
installation layouts.

Always install fi ttings in accessible locations. To avoid
vibration noise, fuel lines should not run against the

appliance or ceiling joists.

Fuel Line Valves and Filter

Install two high quality, oil duty rated, fusible handle
design shutoff valves in accessible locations on the oil
supply line. Locate one close to the tank and the other
close to the burner, upstream of the fi lter for service
access.

Prepare the Burner

General

In most cases, the burner is ready to mount to the
appliance. There can be situations where the burner
needs to be reconfi gured to perform properly in the
appliance. Review the appliance manufacturer’s
specifi cations prior to installing to determine if any
modifi cation is required to properly confi gure the burner.
Instruction on how to perform the following burner
preparation tasks can be found in the Professional

Refer to the appliance manufacturer’s wiring diagram for actual specifi cations.

1.

STANDBY. The burner is idle, waiting for a call for

heat. When a call for heat is initiated, there is a 3­10 second delay while the control performs a safe
start check.

2.

VALVE-ON DELAY. The ignition and motor are

turned on for a 15 second valve-on delay.

3.

TRIAL FOR IGNITION (TFI). The fuel valve is

opened. A fl ame should be established within the
15 second lockout time.

4.

LOCKOUT. If fl ame is not sensed by the end of

the TFI, the control shuts down on safety lockout

RECYCLE. If the fl ame is lost while the burner is

7.

fi ring, the control shuts down the burner, enters
a 60 second recycle delay, and then repeats the
above ignition sequence. If fl ame is lost three
times in a row, the control locks out to prevent
cycling with repetitious fl ame loss due to poor
combustion.

BURNER MOTOR-OFF DELAY. The fuel valve

8.

is closed and the burner motor is kept on for the
selected motor-off delay time before the control
returns the burner to standby.

and must be manually reset. If the control locks out
three times in a row, the control enters restricted
lockout.

5.

IGNITION CARRYOVER. Once fl ame is

established, the ignition remains on for 10 seconds
to ensure fl ame stability before turning off. If the
control is wired for intermittent duty ignition, the
ignition unit stays on the entire time the motor is
running.

RUN. The burner runs until the call for heat is

6.

satifi ed. The burner is then sent to burner motor off
delay, if applicable, or it is shut down and sent to
standby.

Start Up Burner and Set

Combustion

Hot Gas Puff-Back and
Heavy Smoke Hazard

Failure to prime the pump properly could result in
unstable combustion, hot gas puff-back and heavy
smoke.

Do not allow oil to spray into a hot combustion

y

chamber while bleeding air from the pump.

Install a gauge in the nozzle discharge port tubing

y

or fully open the pump bleed valve to prevent oil
spray from accumulating in the combustion chamber
during the air bleed procedure.

Ensure that all bubbles and froth are purged from the oil

y

supply system before tightening the pump bleed valve.

Ensure that the appliance is free of oil and oil vapor

y

before starting or resetting the burner.

Open the shutoff valves in the oil supply line to the

1.
burner.

Open the air dial. This is an initial air setting for

2.
the pump bleeding procedure only. Additional
adjustments must be made with instruments.

3.

Set the thermostat substantially above room
temperature.

4.

Close the line voltage switch to start the burner.
If the burner does not start immediately you may
have to reset the safety switch of the burner primary
control.

5.

Priming the Pump

6.

Prepare the burner for priming by attaching a
clear plastic hose over the bleed port fi tting and
fully opening the pump bleed port. Use a suitable
container to collect purged oil.

7.

Initiate a call for heat.

8.

After the burner starts, press and hold the reset
button for 15 seconds until the yellow light turns on.
This indicates that the button has been held long
enough.

9.

Release the reset button. The yellow light will turn
off and the burner will start up again.

10.

At burner start up, click the reset button while the
igniter is still on. This will transition the control
to a dedicated Pump Prime mode, during which
the motor, igniter, and valve are powered for four
minutes. The yellow light will be on.

11.

Bleed the pump until all froth and bubbles are
purged. If desired, terminate the call for heat or
hold the reset button for at least one second to exit
Pump Prime mode and return to Standby.

12.

At the end of 4 minutes, the yellow light will turn off
and the control will automatically return to standby
mode.

13.

If prime is not established during the four minute
pump prime mode, return to the previous steps
to re-enter Pump Prime mode. Repeat Step 5
until the pump is fully primed and the oil is free of
bubbles..

14.

For R7184 primary controls, see part number 61351
or 61465, for special pump priming sequence.

15.

Prepare for combustion tests by drilling a 1/4”
sampling hole in the fl ue pipe between the
appliance and the barometric draft regulator.

Initial air adjustment — Using a smoke tester, adjust

16.
the air dial (and change fi ring pin on HLX ATC’s, if
necessary) to obtain a clean fl ame. Now the additional
combustion tests with instruments can be made.

○

Direct Venting; typically may not require draft
adjustment.

○

High Effi ciency/Positive Pressure Appliances;
also vary from traditional appliances (see
manufacturer’s recommendations).

3.

Follow these four steps to properly adjust the burner:

Step 1: Adjust the air dial until a trace of smoke is

achieved.

Step 2: At the trace of smoke level, measure the

CO2 (or O2) . This is the vital reference
point for further adjustments. Example:

13.5% CO2 (2.6% O2)

Step 3: Increase the air to reduce the CO2 by

1.5 to 2 percentage points. (O2 will be
increased by approximately 2.0 to 2.7
percentage points.) Example: Reduce
CO2 from 13.5% to 11.5% (2.6% to 5.3%
O2).

Step 4: Recheck smoke level. It should be Zero.

This procedure provides a margin of

○

reserve air to accommodate variable
conditions.

If the draft level has changed, recheck

○

the smoke and CO2 levels and readjust
the burner if necessary

Once combustion is set, tighten all fasteners on air

Section: Perform Regular Maintenance

Shutting the Burner Off

Always keep the fuel oil

supply valve shut off if the
burner(s) is shut down for an extended
period of time.

Turn off all electric power to the burner. Note: There
could be more than one disconnect switch.

Removing Nozzle Line for Service

Correct Nozzle and Flow
Rate Required

Incorrect nozzles and fl ow rates could
result in impaired combustion, under­fi ring, over-fi ring, sooting, puff-back of
hot gases, smoke and potential fi re or
asphyxiation hazards.

Use only nozzles having the brand, fl ow rate (gph), spray
angle and pattern specifi ed by the appliance manufacturer.

Follow the appliance manufacturer’s specifi cations for
the required pump outlet pressure for the nozzle, since
this affects the fl ow rate.

Nozzle manufacturers calibrate nozzle fl ow rates at

y

100 psig.

When pump pressures are higher than 100 psig, the

y

actual nozzle fl ow rate will be greater than the gph
stamped on the nozzle body. (Example: A 1.00 gph
nozzle at 140 psig = 1.18 gph)

Securely tighten the nozzle (90 torque inch pounds). For
typical nozzle fl ow rates at various pressures refer to Table 5.

Nozzle Installation

Perform the following steps when replacing a nozzle.

Remove the nozzle line assembly to gain access to

1.
the nozzle.

Use a 3/4” open-end wrench to hold the nozzle

2.
adapter. DO NOT attempt to remove or replace
the nozzle without securing the adapter, as nozzle
alignment could be seriously affected.

Do not squeeze the electrodes when handling the

3.
nozzle line assembly. Excessive force could change
the electrode tip settings or damage the ceramic
electrode insulators.

Use a 5/8” open-end wrench to carefully remove the

4.
existing nozzle.

Inspect the nozzle adapter before installing the

5.
new nozzle. If it is grooved or scratched on the
sealing surface, replace the nozzle line assembly.
If the surface is damaged, oil could leak at the
nozzle to adapter joint, causing serious combustion
problems.

Protect the nozzle orifi ce and strainer when

6.
installing. If the orifi ce gets dirt in it or is scratched,
the nozzle will not function properly.

To install a new nozzle, place a 3/4” open-end

7.
wrench on the nozzle adapter. Insert the nozzle
into the adapter and secure fi nger tight. Finish
tightening with a 3/8” open-end wrench. Use care
to avoid bending the burner head support legs or
electrodes.

Do not over-torque the nozzle when installing. This

8.
will cause deep grooves in the nozzle adapter,
preventing a seal when a new nozzle is installed.

Carefully check and realign the electrode tips after

9.
replacing a nozzle, ensuring the electrode settings
comply with Figure 11a or 11b.
