EOGB Delavan Nozzle 1.35 x 45 A

The 1.35 x 45 A Delavan nozzle is an oil burner nozzle branded by EOGB and built to the Delavan designation system. It meters and atomises the oil supply so the burner can establish a stable, correctly shaped flame inside the combustion chamber. The nozzle carries the reference D04-0135-45-A.

• Soot deposits building up on the baffles, heat exchanger or boiler flueways
• Smoke or a persistently hazy exhaust reading that cannot be corrected by air adjustment
• An unstable or pulsating flame, or flame lift from the burner head
• Delayed ignition with a puff or rumble on start-up
• Rising CO readings or a combustion analyser result that drifts outside the expected band

• Confirm the flow rating required by the appliance's burner setting, as the nozzle's output must match the commissioned rate
• Check the spray angle and pattern letter against the specification for the burner and combustion chamber concerned
• Verify the nozzle reference D04-0135-45-A against the documentation or the marking on the part being replaced
• Check the nozzle body, thread and seat area are undamaged before fitting, as a poor seal at this point affects atomisation
