Photos of lightweight fi ber tiles for gas service only, installed in smaller mountings designed for new installations
in thin wall furnaces. In both photos the larger assembly for -7 and -8 burners (4-9513-3) is on the left , the smaller

Smaller, lightweight fi ber tiles are available for 4422 Gas burners. They are round, self-supporting, designed for fi ber-lined thin wall
furnaces up to 2000 F operating temperatures.
Standard mounting plate for these tiles is 12

An optional special 16" diameter mounting with compatible bolt spacing is available to retrofi t old thin wall 4422 Burners that need
