NAVIEN COMBI BOILER NCB 240 COIL CLEANING

[@jaydraper6276]

Mega Press is a quick and clean way to install gas piping, but you need to install a union between the gas stop and the appliance.

[@ChuckBarron]

Great eye plumber. Some one caught it....I know i started at unit and had a fubarr.....its my shop and i may know a plumber who can fix it....lol

[@GammaDopplerr]

hi, do you have to open 3 way valve to flush the chemicals out from space heating system?

[@ChuckBarron]

No they are separate.

[@GammaDopplerr]

@@ChuckBarron thanks, but I saw some videos on youtube, when the person was trying to pump chemical into space heating coil, it didn't come out, he said because 3 way valve was shut?

[@amirseyal]

@@GammaDopplerr, I had the same problem with not being able to flush the heating side. Do you have a link to the video where he refers to opening the 3 way valve?

[@kylemierau6367]

took a minute, missing a union on that gas line. im curious to hear if there are pro press unions that would be interesting. I haven't used pro press yet but im getting the chance to in a few weeks at a potash mine. all the mines in the area are hot and horny for pro press cause you don't need to solder/hot work permits, so I cant wait to experience the game changer.

[@ChuckBarron]

Yes....Good eye plumber. I was like dam you idiot....I started at valve and worked backwards and when I was done with gas I said oh crap.....gonna have to use a flex I think. I will check on unions for sure.

[@throttlebottle5906]

lol!

[@higherstandardservice9877]

The pro press is the absolute way to go now, you can press everything all coppers, black iron everything, and they will keep coming up with more. I Think it should become the standard at some pioint soint, that or sharkbiite push on pex, believe it not Im in new england my climate has a big influence on this opinion.

[@tierneymichael51]

It’s mega press not pro press.

[@Falco45able]

No coils in a navian fella , DHW heat exchanger plate, Maine exchanger stainless box small parallel tubes burner above, If you fit a filter on the heat return, and cold water supply you will stop the crap entering the boiler..😉

[@ChuckBarron]

how long have magnetic filters been in effect? thanks for tip falco

[@Falco45able]

Chuck Barron you need to have one fitted on installation, in the uk to meet guarantee criteria, and water scale filter on cold feed! Enjoyed your vid stay safe fella 😉

[@davidabineri908]

Lots of valves being turned on and off with no explanation or close-up video of how to tell which is which. More details would have been more useful. Thanks for the video.

[@eddyvideostar]

Dear Chuck: How can I turn off the Naveen boiler other than the thermostat? It keeps running even though the thermostat is in an off position. Thank you.

[@ChuckBarron]

Eddy, do you have your manual? my navien is the bottom right button. press and hold and it will shut down.

[@eddyvideostar]

@@ChuckBarron To Chuck Barron: Yes. I did view the manual and succeeded in shutting off the boiler. Thank you.

[@mikegartland7756]

I have had many issues with the burner gasket leaking on the heat exchanger. By spraying the top of the heat exchanger, above ignition rods and across front, with leak detector upon start up, you can see how much gas is actually leaking through. This cannot be "fixed" by tightening the 3 screws, Navien will swap out heat exchanger if still under 10 year warranty. This leak will eventually damage the fan, damage the interior of the cabinet and ruin proper combustion. Most units checked do not pass inspection.

[@PARKERBROTHERSPLUMBING]

Chuck, how many days a week do you work? And what time do you run calls?

[@ChuckBarron]

Monday through Friday generally. also what ever it takes especially emergencies

[@heslind]

Do you recommend the combi boiler? I have a 1500 sq house 1.5 bathrooms.

[@ChuckBarron]

Yes. Fantastic set up. I install them all the time.

[@heslind]

@Chuck Barron thanks so much!

[@tierneymichael51]

Go with high efficiency boiler and a indirect water tank. And don’t go with Navien. Go with lochinvar.

[@heslind]

@@tierneymichael51 thank you. One of our quotes was for a Lochinvar combi. I’ll check out the indirect option as well.

[@todddunn945]

If you had three hoses you could do both sides at the same time - pump to domestic in, domestic out to heater in, heater out to bucket. Fresh water rinse both at the same time too. About an hour for the job. Charge 1.5 hour + materials. Teach one of your apprentices to do it and you will make some money.

[@ChuckBarron]

Great idea....I was so focused on doing both coils separate I could of did em both together. I would have to ask tech support first but I don't why I could not. I like all those ideas Todd. Thank you for sharing

[@throttlebottle5906]

you should never flush/clean both into the same bucket/cleaner, for the fact of cross contamination. you never know whats in the "heating side" nasty bugs and high concentrations of heavy metals is possible and flushing afterwards can still leave the domestic side contaminated...........

[@throttlebottle5906]

also good trick is using panty hose or some cheese cloth on the hose coming back to bucket to filter it somewhat ( yes you can go crazy and use high pleated filters setups) ;)

[@ChuckBarron]

oh ok...so you dont mix it back into system.....well it could act like flying brillo pad as it cleans.....lol

[@RunE076]

No isolation valves to do maintenance and galvanized pipes for the expansion tank, that’s some fked up installation

[@ChuckBarron]

Fast, come on dude...all valved off. how did I work on system to do coil cleaning? You know plumbers shop or house is last to get fixed but I for surely set it up to be maintained. Let me know where dawg...also I never put a valve on expansion tank. Ya man....but good eye on expansion and please no FBOMBS here daddy....Plumb On!

[@throttlebottle5906]

side note, you should use separate flushing chemical/fluid from heating to domestic side. or make sure to do the domestic side first. don't want possible contaminates from heating into domestic. even with good flushing you never now, if the heating system never nears the 140F mark, it could be chock full of nasties :)

[@ChuckBarron]

good point. Thanks throttle

[@diymadness2330]

Thanks for all the videos, keep them coming. You should consider branching off from Navien to the AO Smith proline and the Weil-Mclain Aquabalance. On paper, the AO Smith with their warranty and stats, looks the best.

[@ChuckBarron]

Yes, So many options out there. Im open for all suggestions. Thank you

[@hectorcastrellonjr.4058]

Láser Weld Heat Exchangers on Navien... go for longevity

[@broderp]

I just dudnt think you knew what you were doing. If I dudnt know how to do this job already, your video would be confusing to follow.

[@streetgainer]

You’re not suppose to run anything through the heat side, ONLY the domestic side

[@straightupplumbing]

Not according to naviens maintenance manual, section 4.5

[@joshmcfate9687]

Lol brezzzzzz plundering and pillaging... heck yea!!!! It depends on how big there house is.. I sold 2 cleanings the other day 200.00 a unit but i sold more work there too.. typically $275.00 a unit and sell more work while your there... sell sell sell... 🤑🤑🤑

[@ChuckBarron]

man......Sounds good josh....Im trying to get them solder lessons in too.

[@higherstandardservice9877]

not that its gunna kill you but ur supposed to shut off the gas supply nearest the unit "by the book " u keep referring to. Also I didn't zoom in yet, to see what your missing yet either, but i accept your challenge.

[@ChuckBarron]

oh yes...silly on my part..its my shop..I was like of crap.

[@throttlebottle5906]

woah 4 to 5 years, the water must not be that bad then, or it's not used heavily. Many areas here it would have been plugged beyond cleanable within 1 year! nothing like bi-yearly+ cleaning or adding mage costly filtering (yes, I usually suggest they convert back to standard tanks) the closed loop/hydronic heat side shouldn't be that bad if there's no leaks and no make-up water always entering. domestic side yikes!

[@ChuckBarron]

oh wow....some area's that bad? well water?

[@brezzz0077]

$1000.00

[@ChuckBarron]

Bank!! Nice Price Brezzz

[@uttamchauhan1486]

wow that's more than a electric water heater - that's nice business - good they made on demand water heaters
