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 fire, carbon

monoxide poisoning, soot or explosion.

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

Please carefully read and comply with the following instructions:

yNever store or use gasoline or other flammable liquids or vapors near this burner or appliance.

yNever attempt to burn garbage or refuse in this appliance.

yNever attempt to light the burner/appliance by throwing burning material into the appliance.

yNever attempt to burn any fuel not specified and approved for use in this burner.

yNever 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 specifications outlined in the table to the right.

yFor applications beyond these limits, consult Beckett Technical Service at 1-800-645-2876.

yNOTE: Some packaged appliances with burners may be agency listed as a unit to operate beyond these limits. Consult the appliance manufacturer’s specifications and agency approvals for verification.

Notice Special Requirements

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

the carrier at once and file the appropriate claim.

When contacting Beckett for service information — Please record the burner serial number (and have available when calling or

writing). You will find the serial number on the silver label located on the left rear of the burner. See Figure 1.

*Firing rate capacity is based on airflow volume. In the SDC burner, airflow volume and motor speed are proportional to the DC voltage. This results in a lower maximum firing rate at 24V.

Note 1. See equipment manufacturer’s burner specifications for recommended outlet pressure. Pressure is 100 psig unless otherwise noted.

High altitude installations – Accepted industry practice requires no derate of burner capacity up to 2,000 feet above sea level. For

altitudes higher than 2,000 feet, derate the burner capacity 2% for each 1,000 feet above the 2,000 feet.
