Munchkin HX plugging

I got fed up with P.O.S boiler and removed it. It was in my own home so it was naturally the last on my to do list. I inherited problem it was in home when purchased. It was set up for LP combustion test was within factory specs. and sat level. It was piped correct - that was the first thing I tried. Anyway I have since installed a triangle tube solo 110 and love it.

    Munchkin HX plugging

    cleaned EX 3 months ago, plugged again checked trap/drain did combustion test, venting fine - what is causing this?
  • Environmental contamination...

    Looks like your munchie is sucking in some extra goodies. Could also be a contaminated fuel source (LP).

    Could put an air filter on it and reduce the garbage load...

    Are you near some place that genrates a lot of air borne contamination, like open field, corn field, pollen from trees, dusty road, and on and on...

    I changed LP suppliers after the first problem. No combustion pollutants as far as I can tell home is in woods away from dusty roads ect. anybody else have these problems before?
  • Tree pollen...

    can cause problems...

    Pine for sure.

    Based on the yellow tinge, I'd supect that or sulpher as the contaminate.

    Welcome

    to the expensive world of mis-applied mod/cons

    Bill, I'm considering a mod/con for my house. Why is it misaplied here? When are mod/cons justifed? What type of high efficiency boiler would you have used for this installation?
  • Funny...

    I didn't know there WAS an improper application. Enlighten us, please...

  • Right there with you ME.

    I cant agree more.

    Tree pollen may be the culprit, there is nothing but pine in the area. But this happened in the last 3 months, is pine pollen airborne in winter? LP supplier was changed since last problem. Is sulfer a common problem with mod/cons?

    Contamination

    Where's the dryer vent in relation to the intake for this boiler ?

    There shouldn't be enough sulfur present in LP gas to cause a problem. If the solids are sulfur then the tank needs to be cleaned or replaced and the lines flushed.

    dryer vent is on other side of house

    Contaminants

    That is truly excessive. I would make sure the condensate is flowing freely. This can cause buildup if the condensate is flashed off inside the boiler. Make sure your not pulling indoor contaminants. Did you do combustion test? That is a lot of crap in three months.

    better late than never

    I,m new to internet this is my favorite site i couldn't sleeep after i saw picture of this boiler hx man thats bad i'm certain its a leaking hx possible causes:water quality, non barrier tubing with iron pumps/iron components, blocked condensate,piping may not be as per manufacture instructions. correct any installation issues when you replace that boiler.

    Combustion Side!

    Gerry, unless the exchanger is leaking none ox or water(system fluid) should Have nothing to do with this!!

    This is on the combustion side!
  • gerry_6

    Der Heatmeister, so do you agree its the leaky heatexchanger that fouled the combustion chamber destroyed the target wall?
  • gerry_6

    Der Heatmeister, do you agree the leaky heat exchanger caused the combustion chamber to foul so badly and destroy the target wall?

    Pics of boiler piping

    Could you post some pics of the Munchie piping and pumping. Also, are you sure it's set up for LP? You said you did a combustion test, what were the numbers? It may be running way too hot from maybe a natural gas orfice or under pumping causing the condensate to get baked before it drains. The unit really needs to be lower in the back so the condensate drains easily.

    Can be,but i have also seen Contaminated air do this!, Just as Mark E has.

    Also i do not know the extend of the Cleaning!

    I had one similar to that,We had to remove the boiler to clean it in a tub with CLR.

    The exchanger was a PIA to clean and while we were at it we changed the Trap on the Bottom of the Boiler (Dry rotted)

    WE also gave the Boiler pitch toward the Back so that the Condensate can flow better.

    I keep hearing good things about the triangle tube solo 110.

    Jason, thanks for the update on your boiler, that settles that, since HTP warranty is only good to original purchaser I would have done the same thing, enjoy your TT Prestige! Gerry

    Mystery

    I personally like the prestige 10 X than the Munchie..

    I never installed a munchkin but serviced some..

    Starts when they first introduced a SS Condensing boiler without Outdoor reset (They could not integrate a simple old technology with a condensing boiler)..

    Even though you had all of these Problems and are PO about it!

    The boiler did not just produce this problem!

    It still would be nice to know what the Cause of it was....

    EGR?, Improper Adjustments?,Combustion Contaminants?

    Was this boiler installed in a Laundry room?

    Were there Chemicals in the same room?

    As you Know the Munchkin cover is not the best fit and most of the older boilers had screws that mostly were lost or not used!
    Best equipment may still malfunction if subjected to these sort of environments!!

    Like i said before ,i like the Prestige very much!

    Good luck with your new Boiler !?!

    OT : If you are "In the woods" were is your exhaust/Intake air coming from ??

    And a very important question:Sewer or septic system????.

    Richard :)

    boiler was in mech room no chemicals anywhere near it intake & exhaust terminated directly out approx 10 feet. I have septic system - why does that matter? pine woods nearby but happened throughout winter so pollen I don't think was problem

    Do you have a Neutralizer for you Condensate ??
  • Jason_39
    Jason_39 Member Posts: 3


    No neutralizer why?
  • Derheatmeister
    Derheatmeister Member Posts: 1,579


    If your boiler is condensing (Which is what you want it to do hopefully all of the time ) .the condensate is going down you drain into your septic system.

    The PH from the Condensate is Low ,kinda like acid.

    Your poop Breaks down in your septic system because your have an "Nitrobacter" in your tank that helps you with this process.

    When you kill that "Nitrobacter" your septic system is not working so that solids are not breaking down properly

    With that said the solids can enter your leach field which can get clogged up and will be in need of replacement

    I have seen $50000 in redos because of this!!
  • HOW?

    Do you go about treating a new tank with bacteria? We had one installed two years ago and they just pumped it and said the solids weren't breaking down and it's probably becasue thwere's no bacteria. Ahhhh!! We spent $25,000. $15,000 was for sand. :(

    Flue gas re-circ

    I would have a close look at the vent termination, flue gas re-circ is a sure killer of these heat exchangers and yellow/green discolouration is a tell tale sign.

    Bacteria

    Bacteria can be started by throwing a 5 block pound of yeast in the tank.After the tank has been pumped out of course. Even heard of "road kill" being thrown in to get the bacteria going but I use the yeast in mine. Thats why it's not a good idea for antibacterial soap,bleach and tobacco products to be flushed into a tank connected to a septic system.
  • Thanks!

    We just had it done so I guess I'd better get on it. I haver to look more carefully into what's going down the drain. Seems like a gray water tank or something might not be a bad idea. Like for the washer.

    Post purge

    Do these boiler come with a post purge cycle? I've seen this type of problems on gas pack that do not have post purge cycle.
