Figure 11 shows the typical installation for the
gas line. When you have determined how the gas
line will run, locate one of the recessed knockouts
in the firebrick floor (see Figure 12). Firmly tap
the center of the knockout with a chisel until it is
released. Carefully chisel the rough edges of the
hole you have made to smooth edges. This hole
will line up with the hole in the metal floor.
CAUTION: Do not use exces-
sive force to remove the knock-
out. Too much force may damage
the firebrick concrete insert.
A manual shutoff valve, CSA certified and com
-
plying with the
National Fuel Gas code, ANS
Z223.1/NFPA 54
, must be included within (6') six
feet of the vent-free firebox gas supply system. It
may be convenient to install the gas shutoff outside
the vent-free firebox enclosure where it can be
accessed with a key through a wall as shown in
Figure 13. Depending on the type of installation,
some local codes may require you to install two
(2) manual shutoff valves independently accessible
from both rooms. Check your local codes for ap-
plicable installation requirements.

, may be run from the regula-
tor to the incoming 1/2" NPT black iron gas line.
You may also route the incoming 1/2" NPT black
iron gas line directly to the appliance regulator.
Remove the gas line cover plate from the vent-free
firebox’s outer surround and route the gas line into
the rear of the firebox (see Figure 11).
If a sediment trap is not incorporated as a part of
the gas utilization equipment, one shall be installed
as close to the inlet of the equipment as practical at
the time of installation, as per
ANS Z223.1/NFPA
54
. See Figure 14.
