FINISHING FIREPLACE
Combustible materials, such as wallboard,
gypsum board, sheet rock, drywall, plywood,
etc. may make direct contact with sides and
top around fireplace face. It is important that
combustible materials do not overlap face
itself. Brick, glass, tile or other noncombustible
materials may overlap front face provided
they do not obstruct essential openings like
louvered slots or any other opening. When
overlapping with a noncombustible facing
material, use only noncombustible mortar or
adhesive.
3. Repack insulation around gas line and into
sleeve opening. Seal any gaps between
gas line and refractory knockout hole with
refractory cement or commercial furnace
cement, Install gas appliance or cap off
gas line if desired.
