American Granby a00-bn-4050-90 Oil Burner 56000-420000 Btu/h

Product Description

The AMERICAN GRANBY a00-bn-4050-90 is a 120-volt, flame retention oil burner rated from 56,000 to 420,000 BTU/h at 3,450 RPM. It uses a permanent split capacitor (PSC) motor mounted in a NEMA 48M frame, built for continuous duty and extended service life under daily commercial and residential demand. A die-cast aluminum housing precisely aligns the pump and motor to reduce coupling wear. The integrated Genisys burner control, CleanCut pump, Beckett igniter, and one-piece flame retention head work together to deliver consistent, efficient combustion across its full firing range.

This oil burner is suited for residential and light commercial heating applications where a reliable, high-output burner is required. It is designed for forced-air furnaces, boilers, and water heaters that fire on No. 2 fuel oil. The self-centering nozzle line and electrode assembly delivers oil precisely to the combustion zone, while the static plate evens airflow to the head for smooth ignition and stable flame. The electrically balanced and shielded ignition transformer supports consistent electrode performance across the rated BTU range.

Key Features

• Firing range of 56,000 to 420,000 BTU/h covers a wide range of heating load requirements
• NEMA 48M frame PSC motor rated at 3,450 RPM for continuous duty operation
• One-piece flame retention burner head with static plate for even, controlled airflow
• Self-centering nozzle line and electrode assembly for repeatable fuel delivery and ignition
• Genisys burner control and CleanCut pump included as integrated advanced components
• Precisely machined die-cast aluminum housing aligns pump and motor for reduced coupling wear

Compatibility

Designed as an OEM-style replacement or new-install oil burner for residential and commercial heating equipment firing on No. 2 fuel oil, including forced-air furnaces, boilers, and water heaters requiring a flame retention head burner.

Installation Notes

Installation should be performed by a licensed oil burner technician in accordance with applicable local codes and NFPA 31 standards. Shut off all electrical power and close the fuel supply valve before servicing or replacing the burner. Verify nozzle sizing, pump pressure, and electrode gap settings against the equipment manufacturer's specifications before startup. Do not operate without confirming proper combustion through flue gas analysis.
