Photos of lightweight fiber 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 assembly for -2 through -6-B burners (4-9513-1) is on the right.
Smaller, lightweight fiber tiles are available for 4422 Gas burners. They are round, self-supporting, designed for fiber-lined thin wall furnaces up to 2000°F operating temperatures.
Standard mounting plate for these tiles is 12 ¼ " diameter for 4422-2 through -6-B, 14 ½ " diameter for -7 and -8.
An optional special 16" diameter mounting with compatible bolt spacing is available to retrofit old thin wall 4422 Burners that need replacement tiles (the former tile was 12" diameter cast refractory).
The 4-9515-_ tiles have 3" of expanded alloy mesh supporting them on the back end. As indicated, they are field replaceable.
Order them by specifying 4-9515-_ for tiles only, or 4-9513-_ for mounting and tile assemblies (see chart on back).

NOTE: The Mounting Plate and Fiber Tile Assembly must be shipped separately, so that the weight of the burner dœs not damage the fiber-tile during shipment.
WARNING: Situations dangerous to personnel and property may exist with the operation and maintenance of any combustion equipment. The presence of fuels, oxidants, hot and cold combustion products, hot surfaces, electrical power in control and ignition circuits, etc., are inherent with any combustion application. Components in combustion systems may exceed 160°F (71°C) surface temperatures and present hot surface contact hazard. Fives North American Combustion, Inc. suggests the use of combustion systems that are in compliance with all Safety Codes, Standards, Regulations and Directives; and care in operation.
