Is this normal for a brand new Lochinvar NCF150L
Everything I’ve read says the exhaust should be higher than the intake. Would there be any reason for that not to be the case? Mine just got installed and it’s opposite.

Do you have two separate pipes for the flue and intake? Or 1 concentric vent? I would be concerned about exhaust gas recirculation. Can you take a picture of the outside intake and vent?

@ebebratt-Ed Yes, there are 2 pipes. They just replaced the 2 that were there from the last unit (munchkin) i had there. I can get a photo soon but i believe there is one about a foot higher than the other which is directly underneath it. They are about 6' off the ground.

There is a leak somewhere or they fired it up with a bunch of fluid on top which burned off and left this. Can you share a photo of the boiler and piping from a few feet away so we can see how everything is oriented? It appears to be a condensate leak, which would show up while the unit is running. It's possible that they forgot to glue a joint or tighten the flue collar, maybe didn't insert the flue pipe far enough into the collar?

NO!
or maybe. Did the installed spill something and didn't clean it up?

After you make that expensive repair and you still have the same problem, What will you check next?

Edtheheaterman - Not that I'm aware of. the mark on the bottom of the inside seem to have got worse in a few days, i have old pictures i took when i first noticed it.
We're also getting intermittent Lockout errors now that say "fan speed". extremely frustrating being a new unit. Currently they are saying it could be the new digital thermostats using too much power (personally i dont think that's the case but im not a plumber). I'm hoping the Lochinvar rep who my plumber is using agrees to replace the entire unit. Not impressed so far.0 -
Did the installer do a combustion analysis? Not the source of your leak but could be the source of your problems with intermittent firing.

found one leak, the bottom of the drain. Oh don’t mind the wire nut they left behind.
Also wonder if water is coming out of the exhaust? See photo from the top, you can see water marks. Could be leaking down on top of the burner.
what are the chances water not getting drained and collecting up the pipe? I questioned the condensation pump but was told it’s not an issue.0 -
Condensate will form in the vent. It should be sealed and drip either out the termination or run back to the boiler and go to the condensate drain in the boiler. If there are leaks in the vent it will leak out (along with products of combustion).
It looks like it is further up on the vent somewhere than your pictures.
I'm not totally convinced there isn't something wrong with the boiler itself but it looks a whole lot like the boiler is fine and your issues are the result of installation problems.
Did you call the installer? Even the best miss gluing a joint or something every once in a while.Never mind, I see they are giving you some bull about the thermostat instead of figuring out the problem.0 -
They should ship these with a seal on the plug in the vent so you can tell when someone definitely hasn't put the probe of a combustion analyzer in there.

I’m still working with the plumber, the main guy has only been here once In 2 weeks since it was first installed. he’s been sending his younger guys to work through the issues. I’m thinking it’s an install problem too.
All I did was hit the reset button and watched the water start to drip as it started to turn on. Where do I send my bill? (He said half joking)
The condensation pump is empty so that is working.
The spot circled in the photo had a red light on this morning when the error occurred. Idk if that tells you anything.
Also thanks for the help and advice

looking at the top down from where the exhaust exits the case there’s standing water and worn out glue form what I’m guess is the water. The pipe itself is dry on the outside at least. So far.

That orange stuff looks like RTV silicone, i'm not sure why that would be there. If the condensate is dripping on that connector that could give incorrect readings. I'm not sure what that sensor is but the stainless steel wavy thing is a brazed plate heat exchanger for domestic hot water.
It doesn't really look like that joint is leaking but that something higher up is leaking.

Because they did it wrong! Have them show you in the install instructions where that is an approved venting configuration.

that’s what I thought. I’m not a plumber but I knew it seemed wrong. The intake is gonna suck up the exhaust. Thanks for confirming my suspicions. I read the manual and I couldn’t find anywhere that said it was ok to have it below. Smh.

Again, can you please share photos?

They probably connected the wrong pipes tell them to come fix it, nasty work with that foam too lol. That vent goes up pretty far ideally something would support it. Exhaust always goes above intake, or same level, never below

It's been a 3 week nightmare… thank for you for reply.

@GertFellow03, welcome to Heating Help! I've merged your duplicate discussions into one here to prevent confusion. Thanks.

There was a photo of the vents outside showing the vent pipes both coming out at the same level, then the intake goes up several feet and terminates while the exhaust is at the bottom. The pic was lost when the discussions were merged
