K2 WTC combi boiler

I'm having trouble locking my boiler in high/low fire for combustion analysis. Also, manual shows how to install flue attenuator with cpvc flue pipe but as per their options I've used PolyVent piping. I don't think it'll fit in the polyvent socket.

    Having trouble as in you don’t know how to lock it or it won’t stay locked long enough to read?

    I am not familiar with that model. Sometimes you need to give it a big enough load so it won't overheat.

    It won't stay on high fire more than a few moments. I tried with all three zones calling, then I tried wth dhw call.

    FYI- TECH says the harmonic noises can be resolved by removing the 1.5" pvc pipe on the blower intake. Worked for me. I don't have to worry about installing the attenuator.
