Re: Cleaning HVAC Ductwork?
Your right but it wasn't always that way. With modern burners and boilers, I don't consider oil boilers dirty but they have to be set up properly.
I agree that a lot of boilers can go maybe 4-5 years without being cleaned. But they are still thing that need to be done during a proper tune up. Nozzle, filter, electrodes check combustion and oil pressure and test safety controls as a minimum. In fact the nozzle can go many years with clean oil.
Re: Adding a radiant manifold to existing single zone loop
I would purchase a Taco SR 502 (or 503) to operate the zone one and the zone 2 circulators separately using separate thermostats. Here is that diagram
Any Questions?
Re: Need help with Radiant How to go laying panels over existing floor
Thank you everyone for the input, I agree abandon redoing the floor especially having to modify the rest of the house for the new height. @PC7060 The boiler is going to have to have re-piping done regardless of which way I choose to go. Which I'm looking at going towards the Ceiling heat option.
@hot_rod Can you refer me to any training for radiant installation? for the future? any suggestions would be great, or books/ literature . Thank you for your time
Re: Help with screw nut
Be advised we can be more powerful than the metal, it may fail when you succeed.

Re: Where's the capacitor?
I can tell you since those motors first came out, I've never replaced a capacitor. Can't even remember replacing a psc burner motor in the last 8 years.
What problem are you having?

I wanted to follow up on original post because I appreciate everyone's help and wanted to thank you. I had the original installer of the boiler come out and ran another combustion test (results in image). Tech took the sample from under the draft hood. We also discovered a little nozzle looking piece on the ground next to boiler. I believe he said it was an orifice that goes over the pilot burner, and without that orifice on there the pilot would be burning unrestrained and could give some crazy numbers in a combustion test. So basically the tech who took the original test sampled from wrong location and did not reassemble all the parts!

Re: Cost to clean a heat exchanger?
Did the tech leave behind a printout of the combustion test? At 3 years old, that boiler should be spotless inside. At 20 years it should be spotless. If there's soot, then the tech needs to find out why, not just clean it.

Re: Vent piping advice
follow the manual,
except, that air intake, looks weird, I would expect you want the 12 inches from the bottom of the intake gooseneck, to the roof deck directly below the intake, not to bottom of rafters at the deck penetration,
call them and ask to explain why the intake is on the deck

Re: Vent piping advice
Do what is in the installation manual. That is the best advise. If there are several options, then select the one that you are the most comfortable with. But don't just make something up that is not in the manual because of some other piece of equipment used that design. Only use those options that are listed by the manufacturer. If for some reason you have an existing vent from an old appliance that you wish to re-use, then take a picture of that exhaust/inlet vent system and see if you can get the Tech Support people at the manufacturer to approve it. Email is the best way to do this, because you can print their reply and keep it with your I/O manual for future reference.
Re: Vent piping advice
That 12 inch minimum to the rafters on a sloping roof might work — if you never see snow and the roof is flat or nearly so. Otherwise it's just insane.
