Rauschert Ceramic infra-red plaque 26711-8101-101

This ceramic infra-red plaque is a spare part for gas burners. Its dimensions are 34.8 mm in diameter and 12.7 to 14 mm in length. The porous ceramic structure lets a gas-air mixture pass through and become incandescent, emitting infra-red radiation. The part is intended for burners that use surface combustion to produce radiant heat.

Parts of this type are selected by their physical dimensions, which must match the recess or mounting in the burner head. The diameter and length tolerances are intended to fit a specific seat, with the length on the positive side to ensure a snug fit against a retaining element. Before ordering, measure the original plaque and the burner head recess, and inspect the seating area for debris or damage. Choose a replacement of the same dimensions and porous ceramic structure.

Ceramic infra-red plaques of this kind can crack if mishandled or subjected to thermal shock. A cracked plaque allows gas leakage, causes an uneven flame, or leads to improper heat output. To check, inspect the plaque surface for cracks and make sure the burner head seating area is clean and undamaged.
