The gas line connection may be made using 1/2" rigid tubing or an approved flex connector.

(1 or 2) Installation Code.
A listed manual shutoff valve must be installed upstream of the appliance. Union tee and plugged
1/8" NPT pressure tapping point should be installed upstream of the appliance. Figure 30
Install main gas valve (equipment shutoff valve) in an accessible location. The main gas
valve is for turning on or shutting off the gas to the fireplace.
Check your building codes for any special requirements for
locating equipment shutoff valve to fireplaces.
Apply pipe joint sealant lightly to male threads. This will prevent
excess sealant from going into pipe. Excess sealant in pipe
could result in clogged burner system valves.
We recommend that you install a sediment trap/drip leg in
supply line as shown in Figure 30. Locate sediment trap/drip leg where it is within reach for clean-
ing. Install in piping system between fuel supply and burner system. Locate sediment trap/drip leg
where trapped matter is not likely to freeze. A sediment trap collects moisture and contaminants and
keeps them from going into the burner system gas controls. If sediment trap/drip leg is not installed
or is installed wrong, burner system may not run properly.
