it looks like you are exposing your boiler to the serious potential of condensate production, which is not good for an appliance that was not designed for it.

    I should have included more details.
    Sys. temp is mixed temp. from boiler supply and return. boiler gets over 140-180°F depending on the weather and if I've fiddled with the bypass or not.

    Sounds quite reasonable to me. Judging by on-off times, you're operating at about 2/3 of boiler capacity. How was outside temp compared to design outside temp?

    Also looks like a nice and clean gravity conversion. Compression tank looks rather small, but considering how nice everything else looks, I'm sure you sized it properly for the volume of your system.
