Only persons licensed to work with
gas piping may make the necessary
gas connections to this appliance.
NOTE : The gas line connection may be made using 1/2" rigid tubing or an approved flex connector.
Since some municipalities have additional local codes it is always best to consult your local authorities
and the current edition of the National Fuel Gas Code ANSI.Z223.1, NFPA54. In Canada CSA B149 (1 or
2) Installation Code.
A listed manual shutoff valve must be installed upstream of the appliance. Union tee and plugged
sure tapping point should be installed upstream of the appliance. Figure 40
IMPORTANT: 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 40. Locate sediment
trap/drip leg where it is within reach for cleaning. 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.
