Rayburn Bottom Side Brick No1 Old Pattern 47/95 R1682

F/BRICK NO.47-95 IOP R&LHO REG R1682

The Rayburn Bottom Side Brick No.1 (Part Number: R1682), often referred to in trade catalogs as the Old Pattern 47/95, is a specific refractory firebrick used in the firebox of older Rayburn solid fuel cookers. This brick is most commonly associated with the classic Rayburn No.1, No.2, and No.3 models, as well as the early Rayburn Royal (pre-1970s "old pattern" configurations).

Its primary role is to insulate the lower side of the firebox, protecting the heavy cast-iron side plates from direct flame impingement and helping to direct heat upward toward the oven and boiler.

Key Features and Specifications

Part Number: R1382 / R1682.

Pattern Reference: 47/95 (Old Pattern).

Compatibility: Rayburn No.1, No.2, No.3, and early Royal "Old Pattern" solid fuel cookers.

Material: High-temperature refractory fireclay.

Position: Bottom Side (usually sits beneath the top side bricks and adjacent to the firebars).

When to Replace

Structural Erosion: If the brick has worn thin to the point where the cast iron behind it is visible or glowing red during use.

Deep Fissures: Large cracks that allow ash and embers to build up behind the brick, which can cause the side plates to warp or crack.

Crumbling: If the face of the brick is shedding material into the ash pan, reducing the efficiency of the firebox insulation.

Installation Tips

De-ash the Firebox: Thoroughly clean out all old ash and clinker. Any debris left behind the bricks will prevent the new ones from sitting flush.

Dry Fitting: Always "dry fit" the brick first to ensure it seats correctly before applying any fire cement.

Seal the Joins: Use a small amount of fire cement to seal the joints between the bricks. This prevents air from bypassing the firebed and protects the casting joints.

Gentle Initial Firing: Light a small, slow fire for the first 2-3 hours after installation. This allows any moisture in the brick and cement to evaporate slowly, preventing the new brick from cracking due to steam expansion.

Essential Companion Products

Top Side Bricks: Often replaced as a set with the bottom bricks.

Fire Cement: 1kg or 2kg tubs for sealing joints.

Firebars: Replacement "Old Pattern" bottom grates or circular riddling grates.

Operating Tools: Ashpans and riddling tools.
