Rear Refractory Replacement Procedure – Continued
IMPORTANT
If the rear refractory (part no. 83027) was damaged during removal, it
should be replaced with a new part. If rear refractory replacement is
required, a 2 hour burn-in period at a 30% fire rate must be performed to
drive off organic binders. These organic binders are not hazardous
materials, however they may emit an odor similar to burning wood.
