W-M Ultra80, install questions

Ultra prof, advise needed

Hi Guy's >> Just picked up my Utra 80 for install this summer >> While narrowing my search for a contractor who is experianced with the Ultra's, I would like you input on install issues and quirks.

There were some posts that talked about "cracked fittings" and possible relocation of primary wiring? any other know things to look for.

Is it recommended to put the unit up on a raised base for a grade for the condensate line? or just set on the floor>
Boiler will be for oversized Fintube BB, so hope to be operating in the 150-160+ range, so may not reach condensing

Many of the quality install PICs posted here, show the piping mounted to a backboard, given the size of the unit, I would assume this is the standard? as my current is not

Thanks to the wall, setup by D-C-A will be mandatory but so far 2 of my yocals, say it's not needed, so you know they been X'd

Greatly appreciate any input
Rich

Yep, long story

new construction >> 4 times oversized for heat loss , bangbang,>> short cycling you would laugh at>> will be taking legal action against builder and hope to recoupe some cash

spriovent

That taco scoop needs according to specs 18 inches of straight pipe to work correctly go with the spriovent and also do a good heat lose and size it all for low water temp if it's a total re do how about some panel rads then just do a 1/2 pex runs to the panel rads with some trv on them and one distrubtion manifold or as i have with success use some slant fin 80 size it all for design day lose and at a temp of 150 and just use 1 pump no zone valves install some balancing valves to equal your loop lengths out and your set if it's all done right it should cruise along and not cycle to much just modulate down real low .I really like mod/cond boiler they truely shine on fuel savings on the shoulder months and work excellent with low temp systems and high water volume systems with cast iron also .Hope i've help ed peace and good luck clammy

YIKES! 4x oversized...

How does the max output of the Ultra model in question compare?

Not sure what these guy's called themselves

If you notice, the circ is on the return as well>> so the scoop error is in line for thier quality

Fin tube baseboard is running at 88ft x550 btuh >> heatloss is in the low=mid 30K btuh, so hopefully my oversize, will net me the lower run temps

My savior so far [thanks to the input here] to aleviate my short cycling was eliminate a zone [was 2] and just run one big zone {only a 1300 sqft 3bed 2b ranch]

This was a big reduction in short cycling from on and off at the exact same time to running 8-10 mins twice and hr>> but still sucking 140,000 btu in for every firing

So I understand your thoughts on 1 pump and no valves, but i guess that will be in the hands of whoever

Thanks Brian

for the encouragement,,, >> I did alot of research and the Weil was right up my alley

Closest to existing piping

Outdoor reset

Energy Star {After boiler, everything in house will be]

Modulates to were I need to be

Easy convert to Propane [if ever need be]

Software to monitor by computer

Extended homeowner warrantee


I may have read their brochure wrong, it looked like it said the ODR was included. [did they mean a spot on the board] Don't have it in the crate, so I assume I have to buy?

ODR is in the bag....

or at least it is suposed to be according to page 9 in the control supplement....http://www.weil-mclain.com/FTP/Ultra 310/UltraControlSupplement.pdf

Are you or do you have an indirect??
Also if your loads are that light you may want to limit the fire of the boiler to say 45K.... that will keep it from over firing....if you do have an indirect you can let it run up to high fire for quicker recovery, although my 155 modulates back and runs at low fire even when my son is taking one of his twenty minute adventure in the shower....
Disable the "boost" feature and play with the curve and you can make it so the the boiler will not overheat the house no matter how high the wife runs the t-stat too......
I have many of the Ultra's installed and running, and the only problems I had that were not of my own making were surges by the Power Co. Good surge protection may be wise if there are problems in your area....A few of these have been running nostop for a few years now, in a very corrosive AG. application....haven't killed them yet and they paid for themselves a a few months....just in fuel savings.
Keep up the ??'s the only dumb one is the one you don't ask....

Pretty easy to wall mount

even without their expensive hard to find optional bracket. Merely drill the rivits out of the back bracket and bolt it to the wall.

They are fine wall mounted on concrete basement walls. A bit vibration noise when mounted on stud and sheetrock walls. Consider a quieter circ than the one that comes with it

I like to mount them 18" above the floor for easy service. then you don't have to kneel or lie down to work on them. Also leaves room for under mount expansion tank.

The 80 comes with the Taco 007 >> My existing DE-05 also uses the 007 and I can hear it come on/off [right under the master bedroom]

What other quieter circ choices? >>> thanks

Personally

I feel the Grundfos 15-58 is the quietest running circ out there. Speed 2, possibly even speed 1 may be provide enough flow, if piped P/S to drive tha boiler. Lower RPMs generally= quieter operation.

To use your current 40 gallon DHW tank you would need a heat exchanger, and at least one more circ. It may not pencil out to well especially with a tank that has a hole in the center. Be better to get a real indirect some day.

So long as it is

on the outlet of the water meter (I assume you are talking domestic cold water here) I do not see why not. May be a local inspectors thing. I see plugged/capped valves all the time but who knows if anyone saw it to object. It pays to be ready for the future!

One concern they may have is that they do not know what might be connected to it and fear some backflow of some sort, just a guess. But you do have hose bibbs over which they have no control so wonder what they are concerned about.

Key point would be that the connection is on your side of the meter for billing purposes though.

they don't ,make life easy

Brad,,, yes after the cold water meter on the supply inside the house >> Before there was any piping I asked,, they said NO

Uni,,, On the boiler supply and return piping

A couple of more questions

I plan an using a water treatment >> when the boiler is repiped >> Is it feasible to drain the loops and measure volume of water, to get the right mix % ?

Does a Masters licence, entitle a servicer to work in all States, or just the one of the install

BTW >>>
I set my local Lennox up with a couple of trailers for AC/heating? units for thier Demo's >> if you ever see them around, you get to see my craft....
