CFX Vent Free Fireplace System
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 1/8" NPT pressure
tapping point should be installed upstream of the appliance.
Figure 14
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 14. 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.
