FINISHING 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 noncom -
bustible 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.

10 FOOT RULE
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 high -
est point of the roof that is within a horizontal
distance of 10 feet (see Figure 17).
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 appropri -
ate fittings.
1. Remove knockout indentation on refrac -
tory or firebrick wall located above refrac -
tory 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 insu -
lation from gas line conduit sleeve. Save
insulation for reuse. Replace screws.
3. Run a 1/2" black iron gas line into fire -
place 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 cement or commercial furnace
cement, Install the gas appliance or cap
