Service Note

Please note that the 37D0118 valve is similar in design and function to many other SIT valves. These valves look similar but have subtle differences that prevent them from being used interchangeably.

Consult the owner's manual for your propane gas fire appliance before installing a replacement gas valve.  Using an authorized replacement valve will guarantee the safe operation of your fireplace.
