• Precision Combustion: Pre-aligned burner head provides stable flame propagation and reduced soot accumulation.
• Durable Construction: Heavy-gauge materials resist warping and corrosion during thermal cycling.
• Simplified Service: Standard footprint allows for rapid field replacement and reduced labor hours.

Common Questions

Does this burner assembly include the gas orifice?
The assembly typically includes the primary burner tube and mounting hardware; however, verifying the specific BTU rating and orifice size against your serial number is recommended to ensure proper manifold pressure.

What are the signs of a failing Nordyne burner?
Technicians should look for uneven flame distribution, whistling sounds during ignition, or visible cracks in the burner tube, which indicate the need for a 903406 replacement.

Can I use this in both propane (LP) and natural gas furnaces?
While the assembly is compatible with both fuel types, the correct conversion kit and orifice must be installed to match the specific gas supply of the unit.
