The 702GO advanced combination gas/oil burner features Carlin's adjustable combustion head assembly - for unmatched fuel/air mixing, smooth light-offs and quiet running. The automatically-closed air damper and low-high-low step modulation improves efficiency by closer matching the output to the demand and reduces stand-by losses.

• Simple adjustments of the air shutter and combustion head, set with Carlin's easy-access screw adjustment.
• Blower access cover allows full view of blower compartment. Burners use the same air handling parts for all firing rates. Burners use standard components, including Carlin electronic ignitor and standard primary controls.
• Jacob's ladder electrode tips for wide spark pattern and reliable ignition.
• Low-high-low step modulation, using low-and high-fire oil valves and nozzles and butterfly gas valve with motorized air damper. Requires high fire control on boiler by others.
• Positive ignition, stable operation, and compact flame. Gas pilot ignition for gas/spark ignition for oil.
• Compact flame for maximum versatility.
• Insensitive to draft or moderate back-pressure variations.
• Can operate in forced draft applications up to 0.60 inches w.c. positive overfire pressure.
• High resistance to pulsation.
• Excellent performance when tested in appliances that do not use refractory combution chambers.
• Rugged cast aluminum hoursing.
