Don Chamber Lid D10124 Rayburn 8"

Don Chamber Lid D10124 Rayburn 8"

The Don Chamber Lid (Part Number: D10124) is a heavy-duty cast-iron component designed for use with the 8" Don vaporizing oil burner. This lid sits on top of the burner chamber in Rayburn cookers that have been converted to oil (or originally manufactured) using the 8" sleeve burner system.

This is the standard full-size lid for the 8" burner, providing the correct flame path and structural seal for larger Rayburn models like the Rayburn Royal, Supreme, and 212/216 series. It ensures that the heat generated by the burner is efficiently directed into the cooker’s flueways while protecting the internal castings.

Key Features and Specifications

Part Number: D10124.

Application: Standard 8" Don vaporizing oil burners.

Material: High-grade cast iron for maximum heat retention and durability.

Compatibility: Fits 8" burner chambers in Rayburn Royal, Supreme, and Nouvelle oil conversions.

Function: Forms the top seal of the combustion chamber, stabilizing the air pressure around the burner sleeves for a clean burn.

Common Applications

Standard Maintenance: Replacing old lids that have warped or cracked due to years of high-temperature operation.

Burner Rebuilds: A vital part of any full burner overhaul to ensure the appliance operates at peak efficiency.

Efficiency Recovery: Replacing a degraded lid stops "false air" from entering the combustion zone, which helps prevent sooting and high fuel consumption.

Installation and Maintenance Tips

Check the Seating: The lid must sit flat and true on the chamber. Any gaps will cause air leaks, which results in a "smelly" burner and yellow flames. If the chamber rim is uneven, a small amount of fire cement or heat-resistant rope may be needed.

Cleaning: During every 6-monthly or annual service, the underside of the lid should be scraped to remove carbon and scale. This ensures the lid doesn't "grow" in thickness and affect the flame clearance.

Handling: While cast iron is tough, it can be brittle if dropped, especially after it has been through thousands of heating cycles.

Essential Companion Products
