Commercial ultra

Steve_210

I was at a function on Tuesday night where a Weil McLain rep was speaking.
Asked what was that in a MAWP on the commercial ultra his response was 100 psi.
It is an aluminum heat exchanger.
Has anybody seen this on the literature anywhere.
I know Johnny asked this question a while back but I did not see if it was resolved.

I could not find it in the main literature but if you look at the replacement parts list the relief valves go from 30 to 100PSI. You would think they would want to make it a little easier to find. It's a selling and design feature.

3 Pressure relief valve ASME 30 PSI, 1¼” NPT female
ASME 50 PSI, 1¼” NPT female
ASME 80 PSI, 1¼” NPT female (includes new P/T gauge)
ASME 100 PSI, 1¼” NPT female (includes new P/T gauge)
383-600-093
383-600-101
383-600-299
383-600-298

Rob, is this the boiler you are looking for? You have to look farther into the Weil-McLain site. Its under commercial condensing gas boilers.

Better check the literature on their website. 30# is listed currently as the MAWP. It's in their specification.

According to the W-M Website under Commercial Ultra's, you can gang them up, and they come up to 100# if needed. Read the above PDF from their website.
