12Vdc SDC Burner Manual

Section: General Information & Nozzle Assembly Maintenance

General Information

Your burner was designed, installed and adjusted at the factory prior to shipment and should not require additional adjustments. Refer to the Troubleshooting section of this manual when experiencing a possible fault condition.

Adequate Voltage Required

A low or erratic power supply could result in impaired burner operation, severe delayed ignition or an explosion inside the heat exchanger resulting in a burn and/or asphyxiation hazard.

The Model SDC requires a continuous supply of 11

to 16 volts DC at 25 amps measured at the burner during operation.

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.

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.

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.

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.

B. 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

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.

Nozzle manufacturers calibrate nozzle ﬂ ow rates at

100 psig.

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 2.

If the nozzle is already installed, remove the nozzle

3. 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 3.

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.

Inspect the nozzle adapter to insure that the sealing

surface is not grooved or scratched.

To insure that the nozzle functions properly, check the

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

Do NOT attempt to install or remove a nozzle without

securing the adapter to prevent seriously damaging the alignment.

Use care when handling the nozzle line assembly

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

Insure that the electrode setting match the values

shown in Figure 3.

B. Check/Adjust Electrodes

Check the electrode tip settings. Adjust if necessary to comply with the dimensions shown in Figure 3. To adjust, loosen the electrode clamp screw and slide/rotate electrodes as necessary. Securely tighten the clamp screw when ﬁ nished.
