This is a good piece of equipment to have, don't know how I went so long without one. I bought it to keep an eye on my draft during the warm weather, but I find myself looking at it all the time...

. I was guessing on my baro setting without a mano, lucky for my it was dialed in right where it should be! Got my baro fine tuned, draft stays between .04 and .06 with my stove burning from 400* up. Anything below this temp and the draft sits around .03. Big piece of mind for my family knowing exactly what the draft is. Thanks for all the help with the install...

Absolutely.... In my opinion, its nearly a necessity if you want to know what's going on. Without it its like trying to guess how fast you are going thru a school zone while a cop has his speed gun pointed at you

I'd like to install one of these as well. Tcalo, what kind of fittings did you use to connect the copper pipe to the flue, and to to connect the manometer tube to the copper pipe? (please forgive the dumb question).

Not dumb at all, no worries! I drilled a hole in my flue pipe between the stove and MPD and attached a 1/4" compression fitting. Sorry I don't remember what size drill, just big enough to fit the compression fitting. I was able to thread the fitting right into the pipe, but I plan on installing the blank cap on the inside of the fitting when I shut down just for piece of mind. I used a flat washer to be sure it sealed, but I don't think it was necessary. I was worried the plastic line would melt so I ran 1/4" rolled copper from the flue back to the wall and attached it to another fitting. This fitting was 1/4" compression on one side and female thread on the other. I found a fitting that fit the plastic line into it and threaded into the female part of the compression fitting. I hope this makes sense. I've attached pictures to help you out. Any questions just pm me. Good luck!

Noticed online if you purchase the Dwyer A605 kit you get two tubes and two guage assembly's. You only need one to port into the stove right? Plug the other holes on the Magnehelic?

Blue

The mano needs a way to feel the ambient pressure of the room. Don't plug any holes yet. Hopefully someone with a magnehelic will be along to help.

Don't plug unused hole, but to stop debis from easy entry add a short piece of hose/tubing.

Ok im sure its listed in the instructions that I will get, looks like you only put one tube into the exhaust piping though.

Correct.

And the other end of the tube gets connected to the "low" port on the gauge. That way the gauge will display the negative pressure inside the stove pipe.

On the model 25, it's the right-hand port of the two ports on top of the gauge.

Instruction included address nothing in regards to stove or to stove pipes and their measurements.
These instruments have a wide and varied use of applications.
