Key valve components.
Note:
It is recommended to use the key valve assembly provided in the Fire Ring kit. Otherwise, you will need to provide
a key valve for the installation.
Before you begin installing the fire ring into your burner
pan ensure the center hole is a minimum of 1¼ -inch in
diameter (See Fig. 9). Models FG-FR-30SSK,
FG-FR-36SSK, and FG-FR-48SSK come with a ¾” plug,
½” nipple, OAS and FIP x MIP flare fittings (U3-8E-S) and
¾” to ½” reducer (S4100-128).
Note:
The ½” reducer may not be needed depending
on the size of the inlet gas line coming into the fire ring.
These items must be installed into the fire ring as shown
in Fig. 10. Position the Fire Ring port holes facing upward
if using Natural or Propane (LP) gas.
Ensure each NPT
fitting has thread tape or pipe compound.
NOTE:
Flared fittings will not require tape or compound on
the flared side.
Step 1:
Install ¾” plug on top of fire ring and assemble the
remaining parts as shown in Fig. 10.
Step 2:
Install the fire ring through the pan and connect
inlet gas line as shown in Fig. 12 on page 10.
