This was an exact replacement for the old one that lasted about 10 years. kzread.infoUgkx7yWIKcrbA9KMHkGSfcgxW2lsjHT6B8Sh 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

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 ?

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.

How's it holding up?

Should have put all fittings on before hanging on wall.

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!!!

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 🤔

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.

@sykedem_yt6254

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.

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.

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.
