INSTALLING GAS LINE

WARNING: A qualified service
person must connect heater to
gas supply. Follow all local codes.
IMPORTANT: See Connecting to Gas Sup-
ply in your log set owner's manual for
details on gas hookup.
Figure 11 shows the typical installation for
the gas line. When you have determined
how the gas line will run, locate the recessed
knockout 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 dam-
age the firebrick concrete insert.

A manual shutoff valve, AGA certified and
complying with the National Fuel Gas code,
ANS Z223.1-latest edition, 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 applicable installation re-
quirements.

A 36" long 1/2" NPT SCHD 40 flexible gas
connector line complying with the National
Fuel Gas code ANS Z223.1-latest edition,
may be run from the regulator to the incom-
ing 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 instal-
lation, as per ANS Z223.1-latest edition.
See Figure 14, page 11.
Prepare incoming black iron gas line with
Teflon tape or pipe joint compound (check
with local codes as to the use of Teflon tape).
Compounds used on threaded joints of gas
piping shall be resistant to the action of pro-
pane/LP and should be applied lightly to en-
sure excess sealant does not enter the gas line.
Complete your gas installation by connect-
ing the incoming gas line to the appliance
regulator. Secure all joints tightly with
wrench but do not overtighten. If a flexible
gas line is used, take care not to kink the
connector.
