Gas valve question on an American Standard boiler

My gas valve went bad over the weekend.The one we took off was a Honeywell VR8200A 2132.The only one we could find in such short notice and on a weekend was a Honeywell VR8300A 3500.We installed it and everything seems to be working fine.Will this valve be okay to leave on or should I go ahead and find a VR8200A 2132 like we took off??

Thanks in advance,Kevin

From what I read in one of my catalogs, the 8300 would seem to be a comparable valve with a higher capacity. Anytime a gas valve is changed, the gas pressure should be checked so you know you are not putting more or less gas into the appliance than it is designed for.

Thanks for the reply Grady.I know the 8300 had a maximum capacity of 190k btu and the 8200 was 130k btu I think.When I questioned the guy I bought the valve from about this he said there shouldn't be a problem because the burners were regulated by the orifice size I believe he called them.I was just wanting to get a second opinion since I was worried about the difference in the max btu ratings.Do you think I should be worried about the difference or do you think the guy was telling me the truth??

Thanks again,Kevin

Gas Valve

From what I see in my catalog, you should be fine. The 8300 has a higher capacity than did the original 8200. I saw nothing about minimums.

That makes me feel better Grady.Now I just found out another possible mistake we made.We used white teflon tape to help seal the connections.Was that a big mistake and should we redo everything??

Thanks Kevin

Teflon Tape

Most definately a major boo-boo. Take the valve off blow it out well but gently with canned air & reinstall using pipe dope sparingly. Be sure to leak check when done.
FYI: The teflon tape can get under the seat of the valve & cause it not to close completely.

I will definately try and get that done this weekend.Can I use the yellow teflon tape I heard about or should we use the pipe dope?? Didn't know if all teflon tape was a no no to use when working with gas or just the white tape.

Thanks again for all your help.

Teflon tape

Do not use any kind of teflon tape on a gas valve, pipe dope only & then sparingly.
