y

properly sized and in good condition for use.
For those installations not requiring a chimney,

y

such as through-the-wall vented appliances, fol­low the instructions given by the appliance and
power venter (if used) manufacturers.

WARNING

!

Failure to provide adequate air supply could se-

riously 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.

Figure 1. Burner label location

Adequate Combustion

and Ventilation Air Supply
Required

Exhaust fans and other air-using devices
Size air openings large enough to allow for all air-

using devices in addition to the minimum area re­quired for combustion air. If there is any possibility
of the equipment room developing negative pres­sure (because of exhaust fans or clothes dryers, for
example), 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.

Direct air supply and sidewall venting

Some AFG burners are equipped with combus-

y

tion air boots to allow use of outside air for com­bustion.
When sidewall venting appliances, carefully fol-

y

low appliance and power venter instructions for
installation and wiring.

WARNING

!

Follow the Outside Air Kit

Instructions Exactly

Failure to comply could result in impaired com-

bustion, appliance soot-up, puffback of smoke,
and fi re or asphyxiation hazards.

Do not attempt to install outside air piping to the

y

burner without using the outside air kit and in­structions.

SK9475

RWB 6104 BAFG R02 Page 5

Outside air kit applications
Refer to separate instruction sheet supplied with

AF/AFG outside air kit for installation. This optional
kit allows combustion air to be piped directly to the
burner (Beckett part number 51747).

Clearances to burner and appliance

Provide space around burner and appliance for

y

easy service and maintenance.
Check minimum clearances against those shown

y

by the appliance manufacturer and by applicable
building codes.

ting

Verify that the appliance combustion chamber pro-

vides at least the minimum dimensions given in
Table 3.

WARNING

!

Protect Steel Combustion

Chamber From Burnout

Prepare the Burner

Low Firing Rate Baffl e

The AFG Low Firing Rate Baffl e (LFRB) reduces

the air fl ow and pressure. The LFRB is sometimes
used for fi ring rates under 1.00 gph as listed in
Table 4. Refer to the appliance manufacturer’s in­structions. Do not omit the LFRB when specifi ed.
Omitting the baffl e when specifi ed or installing the
baffl e when not specifi ed could result in impaired
burner performance.

Failure to comply could result in damage to the

heating equipment and result in fi re or asphyxi-
ation hazards.

When retrofi tting appliances that have unlined

y

stainless steel combustion chambers, protect the
chamber by lining the inside surfaces with a ce­ramic fi ber blanket, such as a wet-pac or other
suitable refractory material.
Some steel chambers may not require liners be-

y

Nozzle and Pump Pressure

WARNING

!

Incorrect nozzles and fl ow rates

could result in impaired combus­tion, under-fi ring, over-fi ring, soot-
ing, 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 manufac-
turer.

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

y

at 100 psig.
When pump pressures are higher than 100 psig,

y

the 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 Ta-
ble 5.

Check/Adjust ‘Z’ Dimension for ‘F’ Heads

WARNING

!

Adjust the ‘Z’ dimen-

sion to the required
specifi cation.

Incorrect Adjustments could cause combus-

tion problems, carbon deposition from fl ame
impingement, heavy smoke generation and
fi re hazard.

Make all adjustments exactly as outlined in

y

the following information.

Check/Adjust ‘Z’ Dimension - ‘F’ heads

1. The important ‘Z’ dimension is the distance from the face of the nozzle
to the fl at face of the head (or heat shield, if applicable). This dis-
tance for F heads is 1-⅛” (1-⅜” if the air tube has a heat shield). The
“Z” dimension is factory set for burners shipped with the air tube in­stalled. Even if factory set, verify that the “Z” dimension has not been
changed.

2. Use the following procedure to adjust the “Z” dimension, if it is not
correct:

Turn off power to the burner.

y

Disconnect the oil connector tube from the nozzle line

y

See above fi gure. Loosen the splined nut from the nozzle line.

y

Loosen the hex head screw securing the escutcheon plate to the
burner housing.
Place the end of a ruler at the face of the nozzle and, using a

y

straight edge across the head, measure the distance to the face of
the head. A Beckett T501 gauge may also be used.
Slide the nozzle line forward or back until this dimension for F

y

heads is 1-⅛” (1-⅜” to the face of the heat shield, if applicable).
Tighten the hex head screw to secure the escutcheon plate to the

y

burner chassis. Then tighten the splined nut and attach the oil con­nector tube.

3. Recheck the “Z” dimension periodically when servicing to ensure the
escutcheon plate has not been moved. You will need to reset the “Z”
dimension if you replace the air tube or nozzle line assembly. The
Beckett Z gauge (part number Z-2000) is available to permit checking
the F head “Z” dimension without removing the burner from the appli­ance.

Check/Adjust ‘Z’ Dimension - V1 Heads

Figure 5. ‘V1’ Head

V1 heads (see Table below and Figure above for dimensions)

1. See fi gure above. The important “Z” dimension is the distance from
the leading edge of the head to the end of the air tube. This distance
for V1 heads is 1-¾”. The “Z” dimension is factory set for burners
shipped with the air tube installed. Even if factory set, verify that the
“Z” dimension has not been changed.

Set head position adjusting plate (V1 head only)

1. After setting “Z” dimension, loosen head adjusting plate hex head
screw and nozzle line splined nut. Move the nozzle line assembly until
the burner reference indicator lines up with the head adjusting plate
setting number given in Table shown below.

2. Tighten the hex head screw and splined nut. (DO NOT loosen the
acorn nut when setting head position.) Refer to the manufacturer’s in­structions for OEM settings.

3. The position of the head affects air fl ow volume and pattern. For most
applications, the burner will perform satisfactorily with the air adjust­ment plate setting of Table shown below.

4. If combustion results indicate the need for change, adjust the head po­sition adjusting plate forward or back one position at a time to optimize
combustion.

2. Use the following procedure to adjust the “Z” dimension, if it is not
correct:

Turn off power to the burner.

y

Disconnect the oil connector tube from the nozzle line.

y

See fi gure above. Loosen the splined nut from the nozzle line.

y

Loosen the hex head screw securing the head adjusting plate to
the burner housing.
Loosen the acorn nut. Move the head adjusting plate until the “0”

y

lines up with the reference indicator on the housing, and retighten
the hex head screw. Place the end of a ruler at the leading edge of
the head and, using a straight edge across the end of the air tube,
measure the distance to the end of the tube. A Beckett T501 gauge
may also be used.
Slide the nozzle line forward or back until this dimension is 1-¾” for

y

V1 heads. Tighten the acorn nut.
Tighten the hex head screw to secure the head adjusting plate to

y

y

for electrical connections.

Burner installed at jobsite

Refer to Figure 7, for typical burner wiring, show-

y

ing cad cell primary controls. Burner wiring may
vary, depending on primary control actually
used.

The R7184 primary control with valve-on delay

(prepurge) and burner motor-off delay (postpurge),
requires a constant 120 volts AC power source sup­plied to the BLACK wire on the control. The RED
wire goes to the appliance limit circuit. Please note
that other control manufacturers may use different
wire colors for power and limit connections.

Special wiring required with covered

burners

The mounting plate is not a conduit connec-

tion point. Pass conduit and attached connector
through the opening in the mounting plate and at­tach it directly to the burner-mounted 4x4 electrical
box.

If attaching a burner cover to a previously installed

burner, attach the mounting plate and then slide the
conduit into the “J” shaped conduit slot.

Typical Burner Wiring & Burner Sequence of Operation for R7184P Control.

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

Figure 7. – Typical Burner Wiring

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
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 estab-

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

6. RUN. The burner runs until the call for heat is sati-

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

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

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.

8. BURNER MOTOR-OFF DELAY. The fuel valve

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

WARNING

Explosion and Fire Hazard

!

Failure to follow these instructions

could lead to equipment malfunc­tion and result in heavy smoke
emission, soot-up, hot gas puff­back, fi re and asphyxiation hazards.

Do not attempt to start the burner when excess oil

y

has accumulated in the appliance, the appliance
is full of vapor, or when the combustion chamber
is very hot.
Do not attempt to re-establish fl ame with the

y

burner running if the fl ame becomes extinguished
during start-up, venting, or adjustment.
Vapor-Filled Appliance: Allow the unit to cool off

y

and all vapors to dissipate before attempting an­other start.
Oil-Flooded Appliance: Shut off the electrical

y

power and the oil supply to the burner and then
clear all accumulated oil before continuing.
If the condition still appears unsafe, contact the

y

Fire Department. Carefully follow their directions.
Keep a fi re extinguisher nearby and ready for

y

use.

Open the shutoff valves in the oil supply line to the

1.

burner.
Close air band and partially open air shutter. This

2.

is an initial air setting for the pump bleeding pro­cedure only. Additional adjustments must be made
with instruments.
Set the thermostat substantially above room tem-

3.

perature.
Close the line voltage switch to start the burner.

4.

If the burner does not start immediately you may
have to reset the safety switch of the burner pri­mary control.
Bleed air from fuel unit as soon as burner motor

5.

starts rotating.

To bleed the fuel unit, attach a clear plastic hose

y

over the vent fi tting. Loosen the fi tting and catch
the oil in an empty container. Tighten the fi tting
when all air has been purged from the oil supply
system.
If the burner locks out on safety during bleeding,

y

reset the safety switch and complete the bleed­ing procedure. Note — Electronic safety switches
can be reset immediately; others may require a
three- to fi ve-minute wait.
If burner stops after fl ame is established, addi-

y

tional bleeding is probably required. Repeat the
bleeding procedure until the pump is primed and
a fl ame is established when the vent fi tting is
closed.

y

For R7184 primary controls, see Technician’s
Quick Reference Guide, part number 61351 for
special pump priming sequence.

y

Prepare for combustion tests by drilling a ¼” sam­pling hole in the fl ue pipe between the appliance
and the barometric draft regulator.

6.

Initial air adjustment — Using a smoke tester, ad­just the air shutter (and air band, if necessary) to
obtain a clean fl ame. Now the additional combus-
tion tests with instruments can be made

Set combustion with instruments

1.

Allow the burner to run for approximately 5 to 10
minutes.

2.

Set the stack or over-fi re draft to the level specifi ed
by the appliance manufacturer.

y

Natural Draft Applications; typically over-fi re

draft is -0.01” or -0.02” w.c.

y

Direct Venting; typically may not require draft

adjustment.

y

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 shutter/band until a trace of

smoke is achieved.

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

(or O2) . This is the vital reference

CO

2

point for further adjustments. Example:

13.5% CO

Step 3: Increase the air to reduce the CO

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 CO
the burner if necessary

4.

Once combustion is set, tighten all fasteners on air
band, air shutter and head adjusting plate or es­cutcheon plate.

5.

Burner equipped with cover - Reinstall the cover
and repeat Steps 2 and 4 above. If CO2 increases

2 decreases), remove the cover and adjust the

(O
air setting so the CO2 (O2) with cover on meets
requirements of Step 3.
Start and stop the burner several times to ensure

6.
satisfactory operation. Test the primary control and
all other appliance safety controls to verify that they
function according to the manufacturer’s specifi ca-
tions.
