manometer to check draft

manometer to check draft

PostBy: millrrr On: Wed Dec 05, 2012 12:49 pm

hello,
i'm new to the board and have a question i hope someone can help me with. i have a 70,000 direct vent keystoker that when i turn down the stove the fire backs up into the hopper. my grates are sealed properly so i think it might be a draft issue. i would like to purchase a manometer to check the draft using the 1/4 in port hole above the ash door. problem is i dont know much about the manometer and from what the keystoker service guy told me is i only have to check it once a yr? i would like to have one at all times but i dont know which to buy?i did see some digital on ebay but i dont know what specs or if u use the plastic tube or a metal nozzle to put in the port hole on my stove? also will the metal fit in my port hole because they dont give the size of the nozzle? any help would be greatly appreciated, thanks tom

This is what most everyone on the forum uses............including me. It's very simple to operate. Be sure to read the threads posted above for excellent directions on how to use.

Should work fine for any draft measuring on any coal burning appliance..
Yes get the Dwyer Mark II cheap and reliable and easy to read :D

Just a note here: Most of us hook them up BACKWARDS so that the negative pressure is displayed on the positive side of the scale as shown in the picture. Remember that when you install it ;)

Note the scale on the pic posted, it goes from 0 to .3..
There is a Mark II model 27 that goes from 0 to 1.0 DO NOT buy this one, get the Model 25, with the expanded scale.
As it is with the model 25, the portion of the scale we are reading is only about1/2" long, on the model 27, it's about 1/8" long,
not easy to read or use.

Just my opinion .... but I'd steer clear of anything digital next to a stove.

This is the model I have and it works very well.

In the first few posts of this thread, there are links that go into great detail on setting up and using these :)

I would instead recommend a Magnahelic off of Ebay. I have mine connected all the time and I can see the draft in real time anytime.

My Dwyer Mark II is permanently installed also. I would tend to think the Dwyer with the oil would be more reliable and easier to calibrate since its a simpler design. But thats totally an opinion :)
