That gauge will serve you well. Direction are in it. It has a double tube you will only need to use one, the other can just do nothing or I suppose you could peel it off.

Do a search for Manometer Install. There are several pics that will help u.

How to fill it First Turn the lower knob all the way to the left until it stops then unscrew the fill port Put in a little fluid
I mean a little it does not hold a lot Then Turn the knob three full turns to the Right check and see if it is at 0 if not
Turn back to the left all the way and add more fluid Then turn back to the right three full turns check again for 0
Once your at 0 then take one of the tubes and stick it on the low side at the top Then with the other end use a 1/4 "
break tube or copper tube drill a 1/4 " hole in the stack pipe about 10 to 12" before the baro Stick the tube in and slide
the other end of the tube on it Now make sure the Manometer is level It should also be level when filling it with fluid
Your are now ready to use it your draft should be .04 to .05 with the stoker Running adjust the baro to the correct
setting when the stoker is on idle your draft should be .02 or close to it Have fun

What do I stick in the pipe? any 1/4 metal tube? So I stick the hose that comes with it on the meter and this metal tube?

I use a piece of automotive brake line, it is cheap, the meter's hose fits over it fairly easily and you don't have to drill a huge hole to poke the tube through.

Yes, just use the supplied hose to hook the tube to the meter.. the tube is just to protect the hose from the heat of the chimney flue.

I too have my brnady new Mark II 25

break line! I love it.....

ok, do you seal the tube in the chimney pipe?

I would put a piece of small copper tubing with a compression fitting or nut or a piece brake line (1-2') with a fitting, you can just make the hole a bit smaller and thread the fitting into the pipe or use a nut on the back side.

The fittings that come the manometer with will not get the rubber tube far enough away from the stove pipe and could melt.

Read this post, it has pics and write ups

I have mine right into my stove, since it's a direct vent. I have my other one, in the pipe about 2-3 feet from the Baro damper towards to the stove.

I just drilled a hole that is a snug fit for the steel brake line.. the chimney is under a slight vacuum, so flue gasses don't come out, room air is sucked in. You could put in a fitting or use a sealant on the hole around the steel tube if you want..
