Hi everyone,

I have a busted gas valve on my furnace. It is an American Standard furnace that is roughly 25 years old. I have been seeing Honeywell gas valves that are universal that states that they can replace an american standard standing pilot 24volt gas valve. It seems to have the right specs, but I'm unsure if I should do it.

Also, should I just do it myself or do I have to call a HVAC tech? Is there a legal matter with me touching it myself? It doesn't seem to be difficult changing it out. I know that I need to be dilligent about checking for gas leaks. I also know that you want to make sure that any and all wire connections need to be snug to elliminate posible electrical arching. My main question stems behind whether the factory pressure setting will be OK or is there special tools required to adjust the pressure.

A universal Honeywell standing pilot will work if you have a standing pilot valve now installed in your furnace.

There is a bit more to installing a valve than screwing it on the pipe.

Properly mount the valve on the pipe
Use teflon tape or pipe dope for the threads.
Adapt or install a new aluminum pilot line if the original will not work
While you are at it install a new thermocouple and CLEAN the pilot orifice.
LEAK CHECK all gas carring joints.
When all that is done you will have to set the pressure regulator on the gas valve. Sometime they are set at 3.5 in for natural gas but it should still be checked with a manometer to make sure you are not under or over firing the furnace. Read furnace tag and adjust to it.<<<VERY IMPORTANT. Special tool needed manometer.
If you are dealing with Propane call a professional since the valve will need to be converted and adjusted.

Good luck
If you feel you have the tools and the knowledge in how to use them fine. If not call a professional

HVAC thanks again for your help you're the best. I am going to do the procedure myself. I've taken everything you mentioned into consideration. Most of It I was already knew about except for the fact that all I needed a was manometer.

Post back with results

I will do I promise... Hopefully my info will help others
