Rayburn Removable Rear Fire Brick Summer Use R1362

RO4F3-20291 SUMMER USE

The Don Vapour Chamber Lid (Part Number: D10014 / D10114) is a specialized cast-iron plate used in the 8" Don vaporizing oil burner system. This lid is a critical component of the "Vapour Chamber" (VCL) assembly, specifically designed for converted Rayburn Supreme and Rayburn Nouvelle oil cookers.

The Vapour Chamber Lid sits atop the burner housing to create a controlled environment for the oil to gasify (vaporize) efficiently. By maintaining the correct internal pressure and temperature, this lid ensures the burner produces the steady, clean-burning blue flame required for high-output cooking and water heating.

Key Features and Specifications

Part Number: D10014 (often cross-referenced with D10114).

Size: Designed specifically for 8" diameter Don vaporizing burners.

Material: Heavy-duty, heat-resistant cast iron.

Application: Found in Rayburn Supreme and Nouvelle models converted to oil via the Don system.

Function: Seals the top of the vapour chamber to prevent air leaks and direct the flame path into the burner sleeves.

Common Applications

Supreme/Nouvelle Oil Conversions: This lid is essential for the larger, higher-output vaporizing burners used in these specific "wide" Rayburn models.

Burner Overhauls: Replaces original lids that have suffered from "thermal fatigue," manifesting as warping, thinning, or cracking.

Combustion Troubleshooting: A faulty or ill-fitting lid is often the cause of "pulsing" flames or heavy carbon buildup (sooting) in the burner base.

Installation and Maintenance

Air-Tight Seal: For the VCL system to work correctly, the lid must sit perfectly flush on the vapour chamber rim. Any ingress of "false air" will disrupt the vaporization process.

Cleaning: During service, use a wire brush or scraper to remove all carbon deposits from the underside of the lid and the seating rim of the chamber.

Inspection for Warping: Place the lid on a flat surface to check for light gaps. Even a minor warp can lead to inefficient combustion and increased fuel smells.

Thermal Stress: Be aware that cast iron becomes more brittle over time. Avoid striking the lid when it is hot or using cold water to clean it while it is still warm.

Essential Companion Products
