    I just put one up for sale... Old school style (less $$$), works perfectly!

    Easy as can be to use, just need a small tube and whatever method necessary to connect to your particular stove. Since I could take my pressure measurements while the stove was cold, I used modeling clay to form a seal around the tube/hole to prevent any air leaks around the measurement hole. Ideally, you'd want a small fitting that would screw in and attache to the hose, but it's not rocket science.

    Really can't adjust draft (to any real extent) on my stove, so I really only need it once to see what my baseline was. So, might as well make room in the closet and let someone else use it...

    I have Dwyer MARK 22 that bought in a yard sale for almost nothing. Brand new are as high as Ibcynya's. I use a rubber stopper with 1/8" brass tubing bought in ACE hardware to connect in the stove. I have to plug one of the holes for the air wash inlet and connect the meter in the other hole to get better readings. When the 25-PI is cold readings go to 0.3" and hot go to 0.13 - 0.15", anything below 0.10" means the stove or burn pot needs cleaning even with the flame looking good.

    Thanks, I appreciate the thought...It was only $37, so it didn't hurt the pocket book!

    Can a magnehelic be used on Quadrafire Castile stoves? I am not aware of a test port?

    Yes you are right.But what I did was take a reading from the test hole and set the damper.Then I teed into the line at the back.My reading is about .1 inch off the spec.. I just make sure it stays in that new range.

    Sure you can tee it into the vacuum switch hose. But there is no damper adjustment on the quads. So it would be for giggles and maybe keeping tabs on your venting.
