Combustible materials, such as wallboard, gypsum

board, sheet rock, drywall, plywood, etc. may make

direct contact with sides and top around the replace

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.

INSTALLATION

Gas line hook up should be done by your supplier

or a qualied service person.

Note: Before you proceed, make sure your gas

supply is turned off.

Use only a 1/2" black iron pipe and appropriate

ttings.

1. Remove knockout indentation on refractory or

rebrick wall located above the refractory hearth

oor. The knockout indentation must be rmly

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 replace and pull out insulation from gas

line conduit sleeve. Save insulation for reuse.

Replace screws.

3. Run a 1/2" black iron gas line into the replace

through the rear at gas line conduit sleeve (if

using a raised platform, add height). Provide

sufcient gas line into replace chamber for

tting connection (see Figure 19, page 11).

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.
