Pilot Light Adjustment Issue

Hello! I just had my gas valve replaced on our burner. It's a honeywell/Resideo vr8300A3518 and was a direct replacement. It was installed by the people I usually have do any hvac/plumbing work on my house.

The problem is that once it was installed, the technician told me the pilot light was high and that he wasn't able to adjust it. He said it is OK but just using a bit more gas for the higher pilot light. No big deal.

I went to look at it a day or two later and it is pretty high! About an inch tall. I also tried the adjustment screw and it doesn't matter which way I turn it, it doesn't move. Any idea what would cause this? Are the adjustment screws replaceable at all? The valve works fine so I don't want to replace the entire thing again.

As a side note, I purchased the part (new) myself and matched up part numbers. The tech did double check everything was correct and was OK using the part. I don't normally do that but I was going to change it myself before realizing there was pressure limits and I didn't have the right gauges and tools to check them.

Welcome to the forums.

The Honeywell VR-8300A gas valve has adjustable pilot gas pressure.

The pilot flame should envelop 3/8 to 1 /2 in. [10 to 13 mm] of the thermocouple tip.
To adjust the pilot flame:
1. Remove the pilot adjustment cover screw.
2. Turn the inner adjustment screw clockwise to decrease or counterclockwise to increase the pilot.
3. Be sure to replace the cover screw after adjustment and tighten firmly
