D. Inspect Firebox

Surface cracking or crazing of ﬁrebrick material is normal and expected. The following types of cracks are acceptable and do not require replacement of the unit or the ﬁrebox:

•Cracks that do not propagate entirely thru the material.

•Light fracture lines or “spider-webbing” on the surface of the material.

•Cracks that are less than 1/32 in. wide and less than 3 in. long.

•If cosmetically unacceptable, such cracks may be repaired with the SRV-PACK service kit. See Service Parts List.

Cracks that are unacceptable:

•Cracks greater than 1/32 in. wide and 3 in. long are at risk of growing.

•Cracks that penetrate entirely through the firebrick material.

Inspection for cracking should be run when the appliance is cool. Cracks tend to close as the appliance heats up.
