GB 142 Install Pics

Darin Cook_3

We are trying to incorporate more zone valves into our designs to bring down electrical consumption as well as fuel consumption. We used the white tile board as the panel backer. I did not put the Noxon polish to the copper so it isn't all prettied up yet. But here it is. I made it a point to use all cushioned unistrut clamps on the panel. There is zero vibration transmission to the surrounding studs and joists. This system is so quiet you have to open the control on the 142 and see if the green ignition light is on. On a side note I piped the LWCO on the return from the indirect, it was the only place I could get it with no valve between it and the 142.

Beautiful work Darin.

What are all of the zones?

Thanks Ted

With the exception of the 3 slab zones it is all floor warming staple-up ( six zones). It is really about as simple as you can get control wise. People will get tired of me saying it, but this 142 is SO quiet, it just purrs along. People were laughing at us because we were just standing there daydreaming with a silly smile on our face thinking about all the jobs we can do with it.

Nice work! I am jealous we can't use them around here the inspectors will not pass them, I have had eight jobs I could have used them on and three more bids going out within the week that could have gone with them, oh well I can dream looking at your pictures.

Darin,

Nice Craftsmanship, 'was waiting on the other post for the pics.

Explain what's heating if you are just doing floor warming?

The primary heat source is forced air. Two Trane XV furnaces, nice equipment even for air smashers. We are not doing the tin work. Which is good because I am low on bandages.

lwco

question on the location of the lwco, being below the boiler, what good will it do? marc

Nice job Gents, well done !

THAT is how this boiler is supposed to look. Well thought out design.

The code states that there shall be no valves between the boiler and the LWCO, so that in this case or any other with this boiler, it is THE only place it can go. Remember this boiler has a low pressure switch( 10 psi ), so long before the pipe actually empties of water the boiler will have shut itself off. The LWCO is actually a redundant back-up safety in this case or any installation of a GB 142. Thanks for the question.

Thanks for the compliment. I take alot of pride in my piping work. The picture did not come out but I have a poster up along side this boiler right now with Dan's saying " A hundred years from now they gaze upon my work and marvel at my skills and never know my name and that will be good enough for me." That blew the electrician away he said " just think if everyone in all the trades thought like that." Food for thought there huh? Once again thank you for the compliments.

why bother putting it in, if the boiler can run dry, not serving any other purpose. some inspectors have approved the flow switches on the vitodens,11-44, 15-60, but they still want a lwco on the 6-24, 8-32 that have a pressure switch. i believe the lwco instructions want it above the boiler. just seems like a waste of 120 bucks when it wont do anything useful. marc

Great looking job! GB install looks great, fits well along with the near boiler piping! Your pride in workmanship shows. We have been suggesting to install a "U" bend that extends above the height of the top of GB in the domestic return line for the LWCO. Please contact us if any questions.
Thanks,

Constantin

Beautiful Work Darin!

As much as other people gush about the boiler, it's the overall install quality that gets my first vote!

I really like you have supported all the pipes on Unistruts to make them neat, orderly, and happy. The full-port valves with draincocks are a nice touch also, along with the built-in drain in the exaust stack.

The distribution wall is a work of art. So much going on, yet a very clear indication of how much thought went into organizing the whole enchilada before you began. The result speaks for itself.

I did wonder a bit about the TRV you're using for what I presume are the radiant circuits. Wouldn't it have made more sense to use a motorized version like the iSeries to ramp the temperatures up and down? Just wondering...

I'd also like to know more about how you stage the two pumps to feed the six zones... do you turn on the second one whenever more than 3 zones are calling for water or do you use a 3-stage lo, hi, and hi+lo setup to vary the pressure even more?

I also really like how you not only supported the black iron gas pipe but gave it a union too, just in case the boiler has to be replaced in the future. It is curious though to see a SST pipe feeding the black pipe. I suppose you had less to do with the SST than the restof the install?

Again, a beautiful install, congratulations!

Thanks for the compliment Constantin

All the zones are in blocks of three zones. Each block has its own circulator controlled by a Taco ZVC box. All the floor warming zones are controlled by a Wirsbo Floor temp controller. The radiant zones are a garage, a storage area, and the basement. So we opted for the simple Taco # 5000 mixing valve and that will be set at about 85'-90'. Control wise this system is as simple as it gets. The close gas piping is just the standard dirt leg set-up we use. The csst gas piping is something we use alot of here. We do not thread much pipe any more. A few dollars spent on white tile board has proved to be well worth the money for the compliments it gets on creating our pump panels. Thank you for the questions.

That's some really great craftsmanship Darin. The uni strut makes for such a nice neat job, one of these days I'll start to spec it on stock lists. With all of those soldered joints you did, ever think of investing in a pro press? BTW what size GB is that? and who makes those ball/purge valves I see? Those are slick.

The boiler has its own presure switch and will shut down if there isn't any pressure on the boiler. If there is pressure on the boiler it will force the air out of the auto air vent and fill the boiler with water. It may not be the same as the LWCO, but will protect the boiler.
