This was an exact replacement for the old one that lasted about 10 years. czcams.com/users/postUgkx7yWIKcrbA9KMHkGSfcgxW2lsjHT6B8Sh The top of my mitigation tube by my roofline was just a 90 elbow which allowed too much debris to fall down into the fan, eventually ruining it. Without this issue, I bet it would have kept running another 10 years. When I replaced this fan, I added an extra elbow joint so the top tube now it does a 180, which should solve that problem. The radon guys around here wanted to charge me a $300 diagnostic fee, then parts/labor (probably close to $600 total). I installed this all by myself in about an hour for the cost of the fan; it would probably be even easier/faster with two people. FYI the manufacturer's warranty greatly differs depending on whether you install it yourself (1 yr warranty) or have a licensed installer do it (10 yrs).
Good install! But just a warning to you or anyone else looking to embark on this journey of installing a tankless water heater yourself; if you’re not a professional plumber you will get ZERO warranty support from the manufacturer. I installed my Navien myself in 2019 and it’s been perfect, but just keep that in mind.
I saw that same info on Navien but my local plumbing supply place said it’s not true that they provide parts for warranty repair on Navien tankless and no proof that the install was by a licensed plumber is required.
The manufacturer recommends you do a combustion analysis on these units followed by an adjustment of the gas valve or different orifice used if needed. This is one of the advantages of having a professional install
What are you babbling about. This unit is completely automated and adjusts every parameter instantly. As long as you have sufficient gas service and water pressure you walk away
He shouldn't be using dwv PVC fittings. Only PVC Sch 40 to match the pipe. Many of the dwv PVC fittings are made of a thinner PVC. Navien mentions this in their install manual.
You have absolutely got to use pvc solidcore pipe! You cannot use regular pvc dwv piping!!!!! It’s a condensating tankless unit and that vent pipe is not rated for a Navien!! Read your manual!!!
They probably should if they are running a recirc line. The IPC does not require one, but even then most new tankless units have a buffer tank and that creates high system pressure so it never hurts to install an expansion tank.
IPC/ upc requires expansion tank if a PRV is installed on the water delivery line... also with simple knowledge of the plumbing system any pro would put on in.
That extra tank is a safety measure for units that are hooked up to a "city water" connection. Sometimes the water company turns their pumps on and off for whatever reason, and the initial start of their pumps going may cause a very high pressure flow that can possibly damage residential plumbing. So that tank is installed to take the load of that pressure if an event like that were to ever occur.
Cpvc is rated for potable water. Says it right on it. Or are you talking about the black iron? That would be the gas supply. CPVC may be acceptable install per code but I will never use it on new work again. Turns brittle after a couple years.
@@jasonsmith6408 Dan is an old-timer, and that's okay. There's a reason copper is being installed in homes less and less everyday. Just ignore him. CPVC is actually junk and it really does go brittle relatively quickly. I personally would have used PEX, much cleaner look, and doubling the benefits of copper and others.
@@g00fyscientist Nothing looks worse than Pex Cpvc definately looks cleaner but Neither Pex nor CPVC is as good as copper in my book PEX might be better than cpvc though
@@jeffreyplumber1975 PEX has more beneficial advantages than all other applicable potable water lines. Copper has a nice look to it, but that's about it. A big one being time, since in this trade time is money and although it doesn't take a whole lot of time to sweat the joints, I can still clear a whole house replumb with PEX way faster than you can with copper.

What were those products called he applied? My navien went bad n I'm getting a replacement today
@@kevinvarma5603 Just soapy water.

Where do you see that info? I don’t see it in the NPN-180U installation manual/user guide.
A disadvantage of a professional install would be the cost.

I’m learning how to install, just wondering if a check valve go before the expansion tank?
might it have been easier to install the valve set , while off the wall, up side down ?
Is there a maintenance schedule for the condensate neutralizer? Does it need to be changed periodically?
It's recommended to replace the crystals yearly
@@fortunatedad7695 what crystals?
Manufacturing locations in Southern Korea .
My Navien takes around 40 seconds to ignite, is that what your seeing?
Thanks Lance
Sounds like you may have a low water pressure making it tough for the unit to detect flow to start up the unit 🤔
@@fortunatedad7695 does it require 80 PSI?
The plumber jut installed a Navien gas - does it not require a "metal double wall exhaust flue" as this exhaust is HOT ?? thank you ! nice viedo !
Not on high efficiency units just like furnaces.
Exhaust gases are so low because they reuse the heat and expel lower temperatures. Pvc all day long
I'm installing a navien at my house. My hot and cold fittings were loose, just this the in the video @5:58, is that normal?
Yes
How's it holding up?
What was the clear cylinder with all the pebbles in it?
I believe it neutralizes the condensate fluid's acidity.
@@ringodingo yes it's a condensate neutralizer

Should have put all fittings on before hanging on wall.

No flares?
The video is very good. One question. I see more Videos of these because some use an expansion tank and others don't.

I just can’t believe that people still use sea PVC pipe. Worst thing that was ever invented.
Its so common in here in FL. I hate it...
What are your issues with it?
C-pvc*
@@mickeyromero9233 there are no issues, pvc is the only option
What was the extra tank for and I didn’t understand the hookup of the filter?
That extra tank is a safety measure for units that are hooked up to a "city water" connection.

That condensate filter is plumbed all wrong.
agreed
Where is this and who uses cpvc anymore? Well water? Use a tank. You'd have to flush that thing every 3 months with a filter having well water.
Sprinkler pipe? 40 plus years in the biz and I have never seen that. Use copper or hire a real plumber that does.
😂😂😂!

This is a video on how to fail inspection.
Idk I’m assuming you not getting it inspected since you doing it yourself?
Speak…!
Neutralizer is not set up correctly
