INSTALLING GAS LINE
IMPORTANT:
See
Connecting to Gas
Supply
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 the edges. This hole will
line up with the hole in the metal floor.
A manual shut-off valve, AGA certified
and complying with
the National Fuel
Gas
code, ANSZ223.1-lastest edition,
must be included within (6’) six feet of
the vent free firebox gas supply system.
It may be convenient to install the gas
shuttoff 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
shut-off valves independently accessible
from both rooms. Check your local
codes for applicable installation
requirements.
A 36” long ½” NPT SCHD 40 flexible
gas connector line complying with the
National Fuel Gas code ANS Z223.1-
lastest edition, may run from the
regulator to the incoming ½” NPT black
iron gas line. You may also route the
eincoming ½ 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 gear 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 Z223.11-latest
edition. See Figure 14, page 10.
Prepare incoming black iron gas line
with Teflon tape or pipe joint compound
(check with the local codes as to the use
of Teflon tape). Compounds used on
threaded joints of gas piping shall be
resistant to the action of Propane/LP and
should be applied lightly to ensure
excess sealant does not enter the gas line.
Complete your gas installation by
connecting the incoming gas line to the
appliance regulator. Secure all joints
tightly with wench but do not over-
tighten. If flexible gas line is used, take
care not to kink the connector.
UNVENTED (VENT-FREE) FIREBOX
NOTICE: A qualified
service person must
connect heater to gas
supply. Follow all local
codes.
CAUTION: Do not use
excessive force to remove
the knockout. Too much
force may damage the
firebrick concrete insert.
