ARNING
Only persons licensed to work with gas
piping may make the necessary gas
connections to this appliance.
A 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 40
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 28
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 stove.
Check your building codes for any special requirements for locating equipment shutoff valve to
stoves.
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 28. 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.
CAUTION
Use pipe joint sealant that is resistant to
liquid petroleum (LP) gas.
