Fire Rock Conventional and Linear Models 60 and 72 Factory Built Fireplaces Company: Fire Rock Products LLC

PRODUCT DESCRIPTION
Product Solid Fuel Factory Built Fireplaces
Brand Name Fire Rock
Description The Conventional and Linear Series fireplaces are constructed from several precast concrete blocks of various shapes and sizes.  The blocks are assembled with the Fire Rock mortar according to the instruction manual.  The firebox is then lined on the sides, bottom, and back with traditional firebrick.   The formula for the construction of the precast concrete is held by the manufacturer and is reviewed by the regional Intertek inspector for accuracy.
These fireplaces are approved for use with Ciment Fondu and Secar 41 refractory cements for all construction components.  Refractory comprised of Ciment Fondu with 25% recycled refractory material added can be used for the smoke chamber components only.
Models Conventional 60 and 72, Linear 60 and 72
Model Similarity The two models (60 and 72) use all the same materials other than the base, firebox back, and the front and back panels of the smoke chamber, which are larger sections in respect to their size.
Additional models include the Linear Series fireplaces with three tiers of side and back blocks.  The 60" and 72" widths are included in the Linear Series.
