condition for use.
For those installations not requiring a chimney, such as through-the-wall
•
vented appliances, follow the instructions given by the appliance and
power venter (if used) manufacturers.
Direct air supply and sidewall venting

applications.
Combustion air supply
See NFPA Standard 31 for complete details.
WARNING
If the burner is not supplied with a reliable combustion air
source, the burner cannot properly burn the fuel. This would result in
incomplete combustion, causing sooting and possible emission of carbon
monoxide. Severe personal injury, death or substantial property damage could
occur.
Appliance located in confined space
The confined 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 infiltration from the outside.
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.
Outside air kit applications
Refer to separate instruction sheet supplied with AF outside air kit for
installation. This optional kit allows combustion air to be piped directly to the
burner (Beckett part number 51747).
WARNING
You must install the outside air kit strictly following the kit
installation instructions. Do not attempt to install outside air piping without
using the AF outside air kit and instructions. Failure to do so could result in
burner or heating appliance failure, causing potential severe personal injury,
death or substantial property damage.
Clearances to burner and appliance
• Provide space around burner and appliance for easy service and
maintenance.
Check minimum clearances against those shown by the appliance
•
manufacturer and by applicable building codes.
Combustion chamber — Burner retrofitting
Verify that the appliance combustion chamber provides at least the minimum
dimensions given in Table 2.
CAUTION
When retrofitting an appliance that has an unlined stainless
steel combustion chamber, chamber burnout could result from the use of a
high performance burner. Protect the chamber from high temperatures
through the use of "wet-pac" or a similar ceramic liner. Some equipment may
utilize a stainless steel combustion chamber that has been designed and
tested by the manufacturer for use with a flame retention burner, therefore
ceramic protection would not be necessary. Refer to appliance manufacturer’s
instructions. Failure to comply could result in damage to heating equipment.

Service & maintain burner
Owner service and maintenance
Properly installed and maintained, your AF burner will provide years of
efficient, trouble-free operation. Please take care of your equipment by
following the warnings provided and by doing the following (notify your
qualified service agency if you find anything wrong):
Regular Service
Have your burner/heating appliance serviced annually by your qualified
•
service agency, unless an extended service interval has been
determined as follows.
With properly configured burners, there are special Clearburn® practices
•
(such as low sulfur fuels, fuel additive programs, outside combustion air,
high effectiveness filtration, etc.) that can extend service intervals.
Discuss this with your qualified service agency to determine the proper
regular service interval for your heating system.
Daily
Check the room in which your burner/appliance is installed. Make sure:
air ventilation openings are clean and unobstructed
•
nothing is blocking the burner inlet air openings
•
no combustible materials are stored near the heating appliance
•
there are no signs of oil or water leakage around the burner or
•
appliance
Beckett
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.
Warranty
Beckett warrants its equipment specifically to those who have purchased it for
resale, including your qualified service agency (dealer). In the event of any
problems with your equipment or its installation, you should contact your
dealer for assistance.
The Oilheat Manufacturers' Association supports the use of low sulfur fuels as defined 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 efficiency of the appliance.
• Low sulfur fuels reduce particulate emissions.
• Low sulfur fuels reduce oxides of nitrogen emissions.
