Owner’s Responsibility

To the Owner:

Thank you for purchasing a Beckett burner

for use with your heating appliance. Please pay at­tention to the Safety Warnings contained within this
instruction manual. Keep this manual for your records
and provide it to your qualifi ed service agency for use
in professionally setting up and maintaining your oil
burner.

Your Beckett burner will provide years of effi cient op-

eration if it is professionally installed and maintained
by a qualifi ed service technician. If at any time the

burner does not appear to be operating properly, im-
mediately contact your qualifi ed service agency

for consultation.

We recommend annual inspection/service of your

oil heating system by a qualifi ed service agency.

Daily – Check the room in which your burner/appli-

ance is installed. Make sure:

Air ventilation openings are clean and unobstruct-

•
ed
Nothing is blocking burner inlet air openings

•
No combustible materials are stored near the heat-

•
ing appliance
There are no signs of oil or water leaking around

•
the burner or appliance

Weekly

Check your oil tank level. Always keep your oil tank

•

full, especially during the summer, in order to pre­vent condensation of moisture on the inside surface
of the tank.

WARNING

!

Tampering with or altering the burner design

could seriously impair performance, resulting
in loss of static pressure, damage to the system
components, reduced air volume, heavy smoke,
fl ame impingement, appliance sooting, hot gas
puff-back, and asphyxiation or fi re hazards.

Maintain the design to its original confi guration.
Only use parts specifi ed for AF or AFG Burners
Do NOT remove the air guide from the AFG chassis.
Do NOT use ‘M’ Series air tube combinations on AF Burn-

ers.
Never try to convert and AF to and AFG or vice versa
Any design alteration will:

codes, authorities having jurisdiction and the latest revi­sion of the National Fire Protection Association Standard
for the installation of Oil-burning Equipment, NFPA 31 (or
CSA B139 and B140 in Canada).

Regulation by these authorities take precedence over the

general instructions provided in this installation manual.

Notice Special Requirements

y

For recommended installation practice in Canada,
refer to the latest version of CSA Standard B139
& B140.

y

Concealed damage — If you discover damage to
the burner or controls during unpacking, notify the
carrier at once and fi le the appropriate claim.

y

When contacting Beckett for service information
— Please record the burner serial number (and
have available when calling or writing). You will
fi nd the serial number on the silver label located
on the left rear of the burner. Refer to Figure 1.

Combustion air supply

See NFPA 31 Standard for complete details.

Appliance located in confi ned space
The confi ned space should have two (2) permanent

openings: one near the top of the enclosure and
one near the bottom of the enclosure. Each open­ing shall have a free area of not less than (1) one
square inch per 1,000 BTU’s per hour of the total
input rating of all appliances within the enclosure.
The openings shall have free access to the build­ing interior, which should have adequate infi ltration
from the outside.

Inspect/Prepare Installation Site

Chimney or vent

Inspect the chimney or vent, making sure it is

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.
