Burner Application Scope

and Intended Use

The ADC burner is designed for use in road maintenance equipment applications that have DC voltage charging systems capable of sustaining the speciﬁ ed voltage requirements. For other equipment applications, please contact Beckett Technical Services at 1-800-645-2876.

Section: Prepare Before Installing

Prepare Before Installing

Owner’s Responsibility

Incorrect installation, adjustment, and use of this burner could result in severe personal injury, death, or substantial property damage from ﬁ re, carbon monoxide poisoning, soot or explosion.

Contact a professional, qualiﬁ ed service agency for the installation, adjustment and service of your oil heating system. This work requires technical training, trade experience, licensing or certiﬁ cation in some states and the proper use of special combustion test instruments.

Please carefully read and comply with the following instructions:

y Never store or use gasoline or other ﬂ ammable liquids

or vapors near this burner or appliance.

y Never attempt to burn garbage or refuse in this

appliance.

y Never attempt to light the burner/appliance by throwing

burning material into the appliance.

y Never attempt to burn any fuel not speciﬁ ed and

approved for use in this burner.

y Never restrict the air inlet openings to the burner or

the combustion air ventilation openings in the room.

Impaired Burner Performance and Fire Hazard.

Do NOT operate the burner beyond speciﬁ cations outlined in the table to the right.

y For applications beyond these limits, consult Beckett

Technical Service at 1-800-645-2876.

y NOTE: Some packaged appliances with burners

may be agency listed as a unit to operate beyond these limits. Consult the appliance manufacturer’s speciﬁ cations and agency approvals for veriﬁ cation.

12 Vdc ADC Burner Manual

If you discover damage to the burner or controls during unpacking, notify

the carrier at once and ﬁ le the appropriate claim.

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. See Figure 1.

Section: General Information

Adequate Voltage Required

A low or erratic power supply could result in impaired burner operation, severe delayed ignition

General Information

Refer to the Troubleshooting section of this manual when experiencing a possible fault condition.

or an explosion inside the heat exchanger resulting in a burn and/or asphyxiation hazard.

y The Model ADC requires a continuous supply of 11 to

16 volts DC at 15 amps measured at the burner during operation.

y An automotive or small engine charging system that is

capable of supplying the required continuous voltage/ amperage is recommended with certain road equipment, such as asphalt hot patchers and similar applications.

y This is especially true while maintaining nominal load

temperatures during idle periods.

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.

y The burner cannot properly burn the fuel if it is not

supplied with a reliable combustion air source.

y Follow the guidelines in the latest editions of the NFPA

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

(‘A’ in inches see Fig. 2)

A. Equipment Located in Conﬁ ned Space

The conﬁ ned space should have two 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 then one square inch per 1,000 BTU’s per hour of the total input rating of all equipment within the enclosure. The openings shall 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 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, for example), either pipe combustion directly to the burner or provide a sealed enclosure for the burner and provide it with its own combustion air supply.

C. Clearances to Burner and Equipment

Provide space around burner and equipment for easy service and maintenance. Check minimum clearances against those shown by the equipment manufacturer and by applicable codes.

D. Exhausting Hazardous Fumes

See warning on this page. Also be conscious of any fumes produced by the materials that are being heated. Always ensure adequate ventilation to exhaust all fumes.

Section: Nozzle Assembly Maintenance

E. Low Firing Rate Bafﬂ e.

The low ﬁ ring rate bafﬂ e (See LFRB in Replacement Parts) reduces the air ﬂ ow and pressure. The LFRB is sometimes used for ﬁ ring rates under 1.00 gph as listed in

Table 1. Refer to the equipment 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 poor burner performance.

Nozzle Assembly

Maintenance

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.

y Nozzle manufacturers calibrate nozzle ﬂ ow rates at

100 psig.

y When pump pressures are higher than 100 psig, 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 Table 3.

2. Place a 3/4” open-end wrench on the nozzle adapter. Insert the nozzle into the adapter and ﬁ nger tighten. Finish tightening with a 5/8” open-end wrench.

3. If the nozzle is already installed, remove the nozzle line assembly to verify that the nozzle size and spray pattern are correct for the application (per equipment manufacturer’s information). Verify that the electrode tip settings comply with Figure 2.

Use care when removing or installing an oil nozzle

A damaged nozzle could cause impaired combustion, sooting, puffback of hot gases, oil leakage and potential ﬁ re or asphyxiation hazards.

y Inspect the nozzle adapter to insure that the sealing

surface is not grooved or scratched.

y To insure that the nozzle functions properly, check the

oriﬁ ce and strainer for dirt, scratches or other damage before installation.

y Do NOT attempt to install or remove a nozzle without

securing the adapter to prevent seriously damaging the alignment.

y Use care when handling the nozzle line assembly

to prevent changing the electrode tip settings or damaging the ceramic electrode insulators.

y Ensure that the electrode settings match the values

shown in Figure 2.
