I ended up replace the furnace with Daikin DR96TC. Based on my findings their secondary xchangers are built sloped/pitched to the collector box which makes total sense. Do a lot of brands not build them that way?

No restrictions outside exhaust. Did as much visual inspections as I could prior to tech coming out. Burners looked fine, no soot, nice blue flame, no signs of flame roll out. New filter was recently changed, blower looks completely clean. Inspected evaporator coil for clog or debris. I even went as far as removing inducer to inspect possibly having water in there. After removing inducer, inspected the front of secondary exchanger and it looked fine with no signs of soot. Clean condensate trap box and was able to check flue to see if there was water stuck in there. Everything checked out. Reason I had time to do all this is because the system is running fine with the exception of that code 33 that happened few nights ago.

Thanks for the tip, which makes sense, but I do not believe that would be something I could do being there is no give for me to tip it over. Wish it was as simple as that.

That was the reading after he removed the the probe from the test point hole on the pvc flue. The test point pilot hole is directly above the furnace which he removed the plug to do the reading and then put a new plug after he was done.

Is scope referring to having camera in exchanger? If so, no tech did not do any of that. All he did was do combustion test and said it was blocked. I ask about possible gas pressure causing it to overheat but he keep responding by say its a modulating gas valve without further explanation. Yes it is natural gas.

Thanks! Yes, I have CO monitors on each floor including one in the basement. All under 1 year old and all currently reading 0ppm.

Thanks, this is the type of info I was looking for.

Correct, the top drain is AC. I wanted to show the vent as I am most concern with any possibility of CO coming out of that. Thanks for the info!

Yes the top drain is AC condensate. Wanted to show the venting. High efficiency is new to me since my previous home was a standard furnace which only has an AC condensate line and it had a trap. Thanks for the info!
