Installing gas line

WARNING: A qualified ser- vice person must connect heater to gas supply. Follow all local codes.

IMPORTANT: See Connecting to Gas Supply in your log set owner’s manual for details on gas hookup.

You may run the gas line from either side of the firebox (see Figure 11). When you have deter- mined 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.Toomuchforcemaydamage the firebrick concrete insert.

Gas Line Installed Through Access Hole on One Side of Firebox

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.

A 36" long 1/2" NPT SCHD 40 flexible gas con- nector line complying with the National Fuel Gas code ANS Z223.1/NFPA 54, may be run from the regulator 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.

The incoming gas line may be routed into the vent- free firebox either from the left or right hand sides (see Figure 11). Remove the gas line cover plate from the vent-free firebox’s outer surround at the location to be used.
