FINISHING THE FIREPLACE
Combustible materials, such as wallboard, gypsum
board, sheet rock, drywall, plywood, etc. may make
direct contact with sides and top around the fireplace
face. It is important that combustible materials do
not overlap the face itself. Brick, glass, tile or other
noncombustible materials may overlap the front
face provided they do not obstruct essential open-
ings like louvered slots or any other opening. When
overlapping with a noncombustible facing material,
use only noncombustible mortar or adhesive.
opTional gas line
insTallaTion
Gas line hook up should be done by your supplier
or a qualified service person.
Note
: Before you proceed, make sure your gas
supply is turned off.
Use only a 1/2" black iron pipe and appropriate
fittings.
1. Remove knockout indentation on refractory or
firebrick wall located above the refractory hearth
floor. The knockout indentation must be firmly
tapped with any solid object such as a 1/2" dowel
until it is released. Remove fragmented portions
of refractory (see Figure 18).
2. Remove gas line cover plate located on either
side of fireplace and pull out insulation from gas
line conduit sleeve. Save insulation for reuse.

All flue gas outlet chimney terminations must
extend a minimum of 3 feet in height above the
highest point where it passes through the roof and
must be at least 2 feet above the highest point of
the roof that is within a horizontal distance of 10
feet (see Figure 17).
3. Run a 1/2" black iron gas line into the fireplace
through the rear at gas line conduit sleeve (if
using a raised platform, add height). Provide
sufficient gas line into fireplace chamber for
fitting connection (see Figure 19). Note:
Secure incoming gas line to wood framing to
provide rigidity for threaded end.
4. Repack insulation around gas line and into
sleeve opening. Seal any gaps between gas line
and refractory knockout hole with refractory ce-
ment or commercial furnace cement, Install the
gas appliance or cap off gas line if desired.
