FIREROCK ADHESIVE MORTAR
FireRock Adhesive Mortar must be used to install the firebox and FireRock masonry chimney in order for the
FireRock warranty to be valid. It may also be used to install the firebrick, though substitutions are allowed.
Substitutions in the firebox will result in a non-compliant unit and will invalidate the FireRock warranty.
