APPENDIX 5 - REFRACTORY SLABS REPLACEMENT
The intense heat of the fire will normally cause hairline cracks in the refractory slabs. These cracks can be
minimized by proper curing as described in "First Fires". They will not normally diminish the effectiveness of
the refractory slabs. If large cracks develop, then the refractory slabs should be replaced. To replace the
refractory slabs, follow these steps:
1- Remove the inner ash retainer and the
floor refractory slabs (A & B).
3- Remove the rear refractory slab (E).

2- Using a power screwdriver and hex tip 5/16",
remove the slab holders (D) and the left and
right refractory slabs (C).
To install new refractory slabs, follow the above
steps in reverse.
