    hello everyone, Im new to burning wood. I have a clayton 1600m. I was under the impression that you want your pipe that is exiting the furnace to be around 350 deg or so. I thought I was doing well with everything, such as getting my BD all dialed in and getting the firebox up to 450-500 then I checked the exhaust pipe and its steady around 180-200. is this normal or should it be higher? I took the reading about 2 feet past the cast iron collar coming out of the furnace.

    How (with what) are you measuring that?

    Where is your BD with respect to your temp measurement?

    im using a magnetic and a digital thermometer halfway between the 45 coming out of the furnace and the BD. the baro is about 2 and a half feet from the exhaust elbow.

    I don't think I would worry about it if your draft is in spec. You mentioned playing with your BD - but do you know how much draft you actually have? That usually means measuring with a manometer. Even then, if it seems to be working OK, it likely is. External pipe temps are a LOT cooler than what it is inside the pipe - I think I would be more concerned seeing 350 external with a magnetic guage - that might mean it is too hot in the pipe. I have one of those right beside a probe thermometer on my pipe, and when I'm burning the magnetic reads a full 100c less than the probe.

    the draft is spot on at .06. i know the cast iron collar coming out of the furnace is up there in temp. Thanks for the quick response and the help!
