Gas Line & Valve Box Installation
This appliance must be connected to the gas line in accordance with local codes and/or the National Fuel Gas Code, ANSI
Z223.1. After connecting the gas line, all joints in the line and connections at the valve should be checked for leaks before final
positioning of the unit. Conduct a gas leakage test of the appliance piping and control system downstream of the shutoff valve
in the supply line to the appliance.
1.
The valve control box comes with an 84” pilot assembly lead; therefore, the box must be mounted within 5’ of the fireplace
for models ISF24/36/48LB and within 2’ for models ISF72/96LB.
(Figure 35)
2.
Attach the metal enclosure to the studs using standard building materials. The metal enclosure must be mounted in a
location that can be accessed in the future for additional connections & future servicing.
3.
Installation and servicing of gas appliances and ignition systems must only be performed by qualified personnel.
4.
Turn off gas and electricity before starting installation or service.
5.
Make sure gas piping is pressure tested before gas control valve is connected. High pressure can damage the control
causing a hazardous condition.
6.
Make sure piping is clean and free from burrs. Apply a small amount of good quality pipe thread compound or plumbers’
tape suitable for the gas being used. Thread compound should be used sparingly on male threads only, leaving the first two
threads clean.
7.
It is recommended that a safety shut off valve is installed on either the gas in or gas outside of the valve.
8.
It is recommended to hard pipe in the connections with unions installed inside the box.
9.
Uncoil the pilot assembly. Be careful to not create unwanted kinks in the pilot tubing.
10.
Feed the spade connector ends of the pilot hood assembly from inside the fireplace to the outside being careful not to clog
the flared fitting of the pilot tube or damage the spade connectors.
11.
Plug the spade connectors into the module according to the below wiring diagram
(Figure 42)
, insert the pilot tubing into
the right side of the valve, using a wrench, tighten the nut so that the pilot tubing cannot be pulled out

NOTE: Gas and electrical connections
may be brought through the rear wall of
the unit and into the area of the firebrick
cavity. A gap will need to be left in the
firebrick extending from the cavity to the
rear wall of the unit for passage of the
3/8” gas line, pilot tube, and electrical
connections. Ensure all holes are filled
with mortar after installation.
