Final inspection was today.

Tinman

All good. The boiler room was easy. Outside the boiler room, not so much. We ran almost 3000' of Pex-Al-Pex, refitted every radiator and fan coil, pressure tested each one, flushed each one, had to contend with 22" thick stone walls, and brutal crawl spaces but we won.

Next week, we start the SpacePak systems and Mitsubishi ductless splits.

nice job!! @Stephen Minnich .....on the KHN's ...how do you like them? i have a couple scheduled for install this September

Tinman

I love them so far and thank you. We only ran them for a short time for the heating system so we could complete the start-up and combustion analysis. They are running for the indirect/domestic hot water. I still have some fine tuning to do in terms of setting up the parameters but nothing major.

Harvey Ramer

That's a very nice looking job! I'd let you work at my house ;-)

Gordy

Setting the bar Stephen!! Beautifully done.

Tinman

Quite the compliments coming from you guys! Thank you. I learn something from you guys all the time.

EzzyT

Great looking mechanical room.

gerry gill

Damn,that's nice looking!

Paul48

For me.....It's missing one thing. A fridge, because I'd be sitting down there drinking my beers. I'd drive the wife nuts, giving tours to guests. Beautiful Job!

Tinman

Gerry Gill - I'm going to needs guys like you real soon. I'm all in on any steam that comes my way now. Just sold one today. Seems like there's 100 different steam systems.
No discomfort, no growth.

Yeah, the old timers patented the two pipe systems so they all had to do something slightly different from each other..makes it fun tho..I have the paperwork on most of the two pipe systems so if you need something just reach out to me.

Tim McElwain

Steve e-mail me some pictures so I can show them in class. E-mail is gastc@cox.net thanks.

Tinman

Thanks Gerry. I've been watching your videos on YouTube.

Tinman

Be glad to Tim. Thank you.

Nice clean install. Love using strut to make for a plumb, level, professional install. Do you do your own electrical work as well?

SFM

Tinman

Thanks SFM - Yup, I do the electrical too.

That sure is some intense paint on those gas lines!
I sure am liking the KHN's. Just had a problem with one that turned out to not be a problem, but in the meantime was able to speak with a local rep, well 2000 miles away anyway, and was able to get quite a bit more pointers on it. Sure wish I could go to an all day class just to learn all the different capabilities of the control. It can really do a lot of cool things. Especially the ramp delays.
He also informed me the newer ones are being shipped with the gas piping undone so there is less chance of venturi's breaking. Apparently the bouncing during deliveries was causing it. Glad they pay attention and rectify problems when they occur.
Great looking job, by the way.

Nice Mechanical Room, very well done. You take pride in your work and it shows!

Tinman

@rick in Alaska - I painted the concrete pads and the gas lines to differentiate us from the pack, I guess.

I've done the diamond plate thing and it just doesn't appeal to me.

Plus, there's a total of about $15 worth of paint. It was an easy choice.

Danny Scully

You know, if you paint the gas piping, you're suppost to test it under a lot higher pressure

Tinman

Even if I tested before painting?

Last chance leak stop.

Gordy

I think it's a nice balance the pads bring out the hint of red in the Khns.,,...... Omg sounding like the wifey....

Tinman

@Gordy - That's exactly why I used the red.

Smart minds?

Gordy

Think alike

JUGHNE

Where do you locate the probe for the LWCOs?

The instructions show it on the inlet to the boiler, that seems pretty low. The high limit might open first.
I put mine higher thinking to maybe save a pump from running dry. FWIW

Tinman

They're about 8" above the boiler. They're hard to see because the bull of the T is facing the back wall and the wire is tie strapped on the back side of the pipe down to the control.

JUGHNE

That is about where mine is located.....my I&O papers had it where I thought it was too low.

However will your boiler inlet & outlet isolation valves isolate the each probe from its respective boiler?

Did that test tee in the exhaust come with the boiler?

I like the looks of your installation....very neat.

Tinman

The boiler isolation valves won't and I may change that on the next one. There are other valves on the system side where everything on the boiler side can be isolated. That's how I wanted it really. If the gaskets on the Caleffi Sep. ever have a problem I'm covered there too.

Those test tees did come with the KHN's. I love that.

Thank you. I've never been 100% satisfied so I'm always looking for ways to get better. I'm not sure that's a good thing or a bad thing or an OCD thing?

ChrisJ

Did you clearcoat all of the copper?

Tinman

Not yet but you gotta know it's coming

ChrisJ

I'll be honest,
It'd look better if the boilers came in black diamond plate.

Can you imagine giving a customer options for their mechanical room similar to when someone is buying a car?

JUGHNE

What I mean is if you shut down boiler A, closed the in/out valves for A (leaving B unit in operation) and drained that boiler A , would the LWCO A be dry when boiler A is dry.

So LWCO A is not sensing water from the wet system and able to fire IF it was somehow powered up while dry?

Sandcloth and Scotchbrite work on the copper is part of the annual service agreement isn't it?

Tinman

Not with the valves closed, no. But each individual boiler has its own on/off switch and I added another for each. If someone is going to drain a boiler, they better have sense enough to turn off that boiler. Yes?

Tinman

Lock out/tag out and all that stuff. Me? I'm turning power and gas off.

JUGHNE

I realize that isolating the LWCO from the boiler is not like having a valve between the boiler and the PRV (pop off).

But to clean that probe in the future, you would have to drain more piping and that would shut down the other heating source.

Common sense doesn't always exist as we all know. You never know who will be putting fingers in the wrong place.

For instance:
I repaired a pool heater in May, it is 70 miles away.
Last week a call that the electronic t-stat I put on it is not working, the display is dead.
I called back 3 times with really dumb questions:
Is the CB on?
Is the pilot control switch on?
Did you reset the high limit t-stat?
Each call the 2 maintenance guys replied those items were OK.
(I know they were thinking.....do you think we are dummies or what?)

I drove 140 miles round trip to reset the emergency pool heater shut down switch next to the CB panel.........Damn! they said....that happen last year too!

keyote

Not A plumber but in NY painted gas pipe must be tested at 20 lbs not 3 lbs so if there's an addition to system or if say the gas company shuts system because leak or even bill payment or between owners, when its re commissioned the test must be done at the higher pressure. theory is paint could mask minor leaks. reality is higher pressure might even cause them. people buying old houses often find themselves having to re pipe four stories of gas before service will be restored. I know this happened to me.

Fred

I don't know what other state requirements are but here in Ohio (at least our local utility, Vectren, says it is a State PUCO requirement) requires a physical, inside inspection from the meter back to where the pipe enters the house every three years. They schedule it and if it is not completed within 30 days of that scheduled date, they shut the gas off at the street and the home owner then has to pay a "Turn-on fee, and when they come out to turn it back on, they complete the inspection. It's not a pressure test though, they just use a detector at each connection up to and around the meter. If there are gas appliances connected within a few feet of the meter, they check those as well.

Tinman

Gas pipe installation was complete and leak tested long before any paint was applied.

Yeah, that would be the smart way......

jonny88

You make it look easy.I bet that boiler room was laid out in your mind before anything went in there.Fantastic work,thanks for sharing.
