This valve replaced an older one in a gas fireplace. However some changes were required to the connections. The old valve used two thermocouples, one for the pilot flame valve, and one for the main gas valve. This one eliminates the thermocouple for the pilot, and uses the one for the main gas valve to also maintain the pilot, via a jumper wire to the pilot flame valve. Also, the old valve used 1/8 inch gas tubing for the pilot flame whereas this valve uses 1/4 inch tubing . So a short piece of 1/4 inch tubing is needed along with a 1/8 to 1/4 adapter. The 1/8th tubing must be cut to connect the adapter. No changes were required for the main input and output gas lines. Also note this valve does not have a level control. One, available from Robertshaw, can be added.
