Honeywell 1020 Manual

[Latanya Hariri]

AmericanStandard hasn't made boilers since 1974, but I am hoping someone may have knowledge on replacement options. I am hoping Honeywell, or some other manufacturer, may offer a gas valve with similar specs that may work.

That must be a pretty big boiler. Codes have changed since then, you'd now need a redundant (dual-seated) gas valve, or a second valve. Also, not sure what the pilot setup is, but it would now have to be 100% shutoff, where the thermocouple would shut off the pilot gas as well as the main burner gas if the pilot goes out.

Is that the rule for reparing the existing equipment in your area @Steamhead? I might think that equipment passed inspection when installed many years ago and might be grandfathered in. If however, you were to make any type of upgrade like adding electronic ignition then you would be required to bring it up to today's standard. then the pilot valve would need to be incorporated into the 100% shutoff control system with additional manual reset limit controls and the like.

I agree that you have a valid point about making it safer, but you may not be able to just make one part of the system safer without going the full FM, CSD-1, CFR or what ever applies to the AHJ. Make one change and you have to bring it up to code. Keep it the same and leave it the way it is. "All or Nothing"

I might argue that the Honeywell V8943A is the direct replacement even though it is not equipped with the manual lever for power failure. that will in it self make the system safer by using the available honeywell replacement valve. Time was if an inspector wanted to be a hard a** you would need to use OEM specified parts. That is where cross reference charts become important. If the literature in the box with the part had a list of all the previous models and brands that the current part is a direct replacement for, then you were good to go. I was unable to find that list for this valve, however the size and BTU capacity are within the capacity of the boiler specifications. Just don't install it wrong. If it is as standing pilot system, there may already be a Penn Baso thermocouple safety already there pilot line.

I would need to see it in person to evaluate the safety of repllacing the valve vs. a comlete new gas train. The burners mignt not be in good enough shape to allow the boiler to stay in operation. I was just offering the answer to the question posed. "Looking for help replacing an old V530 Gas Valve"

I think that it is good to have others voice the concerns in case @diesteldorf is a DIY building owner with no boiler experience. If @diesteldorf is a first time contractor with boiler experience then he has come to the right place to find help on really old stuff.

I don't think any specific information should have been given to the OP. If he came here for that info then we know he's not a tech. And what he's asking about can go boom. Why give him the match? Oooh! Nice double entendre!
