Post Furnace gas valve replacement

Hi!

My Westinghouse gas furnace has been disconnected by the gas company because it wouldn't shut off the gas when the pilot light was out. I think I need to replace the gas valve.

Furnace details:
Model FGBE137MA
Series NIBE
Serial M38778
The gas valve has a serial number of V8146A 1017, and though I can find a (vintage) V8146A 1033 for sale, I can't find mine.
Input BTU/hr: 137,500

Photos.

The PG&E guy said that the valve should be replaced by one with a rating of within 5% of 137500. I've been looking and I've come up with these two:

VR8300
VR8200

The first one seems better because I do have a 12" input and a 3/4" output (by my reckoning) but it's 190000 BTU/hr which is significantly more. The second one has a 130000 BTU/hr which is just about 5% less than my furnace is rated for, but it has a 1/2" output and so I guess I'd need an adapter.

Which one is better, or would you recommend another one entirely?

Thanks in advance.

Replacing a gas valve is best left to a service agency that knows what they are doing.

You don't have the skill and judgment to do the job.


Sorry.

Sorry.
I'm not planning to do the replacement myself. I had a guy come out but he was more interested in replacing the furnace than fixing it, and he said he'd 'look for' the replacement part but I don't think he's going to. He'll install it, but I said I'd find and buy the part.

Replacement Valve

I searched Honeywell's site for a replacement for your V8146A-1017 valve. They suggest a V800A-1070.

Thank you! That's a good recommendation. I was on that site earlier but wasn't able to find that.

I'm surprised the PG&E guy is such a schlub.


You need a gas valve that has a greater capacity to pass gas than the BTU input for your furnace (presumably the 137500 you mention).

The gas input to the match your furnace is adjusted with a pressure regulator built into the gas valve. Correctly adjusting the burner input is one of several reasons why replacing a gas valve is not a good DIY job.

What was the symptom that this was found out?

Does this furnace only have a thermocouple or flame sensor at the pilot?, Or is there also one for the burners?
