in damage to the equipment, asphyxiation, explosion or fi re hazards.
The burner cannot properly burn the fuel if it is not
•
supplied with a reliable combustion air source.
Follow the guidelines in the latest editions of the
•
NFPA 31 and CSA-B139 regarding providing adequate air for combustion and ventilation.
See NFPA Standard 31 for complete details.
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 burner or provide
a sealed enclosure for the burner and supply it with
its own combustion air supply.
Inlet Ring
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 70 equivalent feet.
Allow 6 feet for each elbow.
1. Remove the inlet cover.
2. Insert 4” duct into the inlet ring.
3. Fasten duct into place using at least 3 sheet metal screws evenly spaced around the inlet ring.
Refer to Figure 2.
4. Remove the barometric draft control unless it is
in the same atmospheric pressure zone as the
inlet.
On the outside of the home use a 90° elbow pointed
downward with a 1/4” mesh screen over its opening.
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.

Fuel Line Installation •
CAUTION
!
Damage to the pump could cause impaired burn-
er operation, oil leakage and appliance soot-up.
Never use Tefl on tape on fuel oil fi ttings.
•
T ape fragments can lodge in fuel line components
•
and fuel unit, damaging the equipment and preventing proper operation.
Use oil-resistant pipe sealant compounds.
•
For fuel line installation, continuous lengths of heavy
wall copper tubing are recommended. Always use
fl are fi ttings. Never use compression fi ttings.
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 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.
Do Not Use Tefl on Tape
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
Maintenance section.
•
Remove / install burner nozzle
•
Check head/air adjusting plate
•
Mount Burner on Appliance
Verify that the air tube installed on the burner pro-
vides the correct insertion depth. Refer to Figure
3.
The end of the air tube should normally be
1/4” back
from the inside wall of the combustion chamber.
Never allow the leading edge of the retention ring
to extend into the chamber, unless otherwise specifi ed by the appliance manufacturer.
NOTICE
For protection in the event of fi re, some states require the
shutoff valves to be a fusible-handle design. R.W. Beckett Corporation recommends this design as good industry
practice for all installations.
NOTICE
To further protect the fuel supply system and reduce noz-
zle orifi ce plugging with fi ring rates below 0.75 gph, a dual
fi ltration system can be installed. This typically consists of
a 50 micron primary fi lter, located near the fuel tank and a
secondary fi lter rated for at least 10 microns located near
the burner.
Also install a generous capacity fi lter, rated for 50
microns or less, inside the building between the
fuel tank shutoff valve and the burner. Locate both
the fi lter and the valve close to the burner for ease
of servicing.
Bolt the burner to the appliance using the factory-
welded fl ange.

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 100 psig.
This burner utilizes pressures higher than 100
•
psig, so the actual nozzle fl ow rate will be greater
than the gph stamped on the nozzle body . (Example: A 1.00 gph nozzle @ 140 psig = 1.18 gph)
For typical nozzle fl ow rates at various pressures see ac-
companying chart.
Turn off power to burner before proceeding.
1.
Disconnect copper oil connector tube from noz-
2.
zle line.
Loosen the screw that fastens the rear access
3.
door.
Remove splined nut.
4.
5.
Remove the nozzle line assembly from the burner, being careful not to damage the electrodes or
insulators while handling. Stop halfway to remove
igniter/transformer wires.
6.
To replace the nozzle assembly, reverse the
above steps. “HLX” head air tubes – Be sure stop
screw is fastened securely. Seat stop screw on
back of choke ring to set the position of the head.
“FBX” head air tubes – Use T gauge to set the “Z”
dimension to 1-1/8” +/- 1/32”
Nozzle Installation
•
Perform the following steps when replacing a noz-
zle.
1.
Remove the nozzle line assembly to gain access
to the nozzle.
2.
Use a 3/4” open-end wrench to hold the nozzle
adapter. DO NOT attempt to remove or replace
the nozzle without securing the adapter, as nozzle alignment could be seriously affected.
3.
Do not squeeze the electrodes when handling
the nozzle line assembly. Excessive force could
change the electrode tip settings or damage the
ceramic electrode insulators.
4.
Use a 5/8” open-end wrench to carefully remove
the 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 in-
6.
stalling. 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 install-
8.
ing. This will cause deep grooves in the nozzle
adapter, preventing a seal when a new nozzle is
installed.
Carefully check and realign the electrode tips af-
9.
ter replacing a nozzle, ensuring the electrode settings comply with Figure 6a or 6b.
If the head was removed when replacing the
10.
nozzle, carefully reconnect the head to the nozzle adapter. Push the head support until it stops
against the nozzle shoulder. Verify the dimension between the nozzle face and the back of the
head is 5/32”.

The Oilheat Manufacturers’ Association supports the use of low sulfur fuels as defi ned by ASTM D396, Grades No. 1 Low Sulfur
and No. 2 Low Sulfur, as the preferred heating fuel for the following reasons:
• Low sulfur fuels reduce deposits on heat exchanger surfaces, extending the service interval between cleanings.
• The reduced deposits increase the effi ciency of the appliance.
• Low sulfur fuels reduce particulate emissions.
