Question of Space and ASME or UL for Boiler

Question of Space and ASME or UL for Boiler

PostBy: Buck60 On: Mon Jul 07, 2008 9:18 pm

I've been lurking for a while and thought I had it just about figured out...then the bldg inspector said that anything going in would have to be listed by UL, ASME or some other recognized organization.

Thought of putting a Keystoker KA-6 multi-fuel (coal & oil) in place of the current boiler (112,000 net btu) but the current space is wedged between the base of the chimney and the stairs to the basement and is 6'4"l x 4'9"w. No extra flues. Another thought was to direct vent (there will not be another chimney says the boss) a KA-6 or KAA2 about 18 feet away, plumbed in with the current oil unit. It appears the current boiler space may be too tight for the KA-6, and I don't believe Keystoker has an ASME rating.

The AHS s130 has the ASME listing, looks compact could go into the chimney (not a direct vent candidate) as long as I could move the oil unit and direct vent that (tbd). The EFM multi-fuel would be great, but is too large for current boiler spot where the flue is, and a real coal bin would be difficult.

Does anyone have suggestions of units or configurations that might satisfy the building inspector? I'm thinking of 1) a listed unit that can be direct vented, 2) a compact multi fuel option that can go in the current flue 3) compact coal unit into the flue, provided I can direct vent the current boiler (tbd). I really want to go with coal, but the space in our basement (half of which used as a garage) is quite limited. Thanks in advance.

The AHS can be had with the ASME stamp but it will cost a lot more. Axeman-Anderson and EFMs are stamped and I think the Keystoker is too. They make boilers over 1,000,000 BTU's, I'm sure some of those will have an H stamped on it somewhere.

I'm not sure why he would accept a UL approval for a boiler install.

There are no UL rated boilers. UL labs does not rate, test or spec pressure vessels. A boiler my have electrical or other devices that are UL rated but that does not make the entire boiler UL rated.

Yes, I know the UL does not get involved with the boilers told the inspector so when he mentioned it - he then went on to say it had to be listed by someone like the ASME, or another recognized agency (if one exists), the point being he wants it to see some sort of listing.

Keystoker says they have an ASME relief valve and the design conforms to ASME guidelines, but that they don't have the units checked by the ASME. It may be Keystoker can provide enough info. to satisfy the inspector. If not, I'm not sure how best to proceed.

I went through the same thing when I was looking at boilers. I went down to the building insp. and showed him the info. on Keystoker, asked him if he would call them,I didn't have the extra money to go with AA or AHS system. A few hours later he called me back and said that the pressure relief valve is ASME cert. and that's what he was concerned with. Try talking to your building insp. maybe he's willing to listen and make a call for you.

I second talking to the inspector and have him talk to the people who build/designed your boiler.
This may answer any question he had/has with the boiler and you do not get involved in his 'education'.
The manufacture has all the engineering staff to overcome most objections a inspector may have other than code requiring the actual certificate.
Seems to me the inspector is carrying over the type of tag/cert from wood/coal stoves to the boiler arena.
