Manometer & Powervent Advice Please

Manometer & Powervent Advice Please

PostBy: bud bubba On: Thu Oct 30, 2008 4:33 pm

I have a Poconno top vent that also uses a power vent with a barometric damper. after removing the stove pipe for cleaning the damper did not seem to operate right, and I am not sure what the counter weight was set at prior but. After Playing around with it now it is set at .02 I attached a Dwyer Manometer to the pipe below the BD and set the power vent to achieve a .045 setting. the question is why do I need to turn the power vent to near a lowest setting to get this reading, as last winter when the unit was set the reostat was nearly at 50% as the installer marked it. Is this reasonable or am I running this wrong?

I'd guess that last yrs installer didn't use a gauge, or wasn't familiar with what you needed. If the book calls for .045 and that's what you have it set at, you're all set. The reason that it is set so low is that a powerventer fits many things. Your thing just doesn't need all the powerventer power.

The rheostat on the power vent will not give you an exact reading at the very same point everytime. Its not calibrated that close. I think I would try a 3 or 3.5 setting for draft.

After the fact, I have realized the barometric damper counter weight had been installed in the wrong position. after looking at long enough I read on the damper that for horizontal installations the weight should go on the left scale slot and it has been in the right slot that is for vertical pipe installations. I corrected this and set it at the 2 setting and still getting .045 on the mano with the PV reostat at the lowest setting. :shock:

Bud,
Inside the rheostat box, on the rheostat itself, there is a fine tuner. You need a very small slotted screwdriver to turn the adjuster. This will fix the problem. Make sure you have the electric unplugged. BE CAREFUL, don't call me with a burnt out rheostat. :)

Thanks for having patience with some of us on this forum I''m sure most of these questions have been answered several times before and is posted somewhere on here. I found the adjustment screw you mentioned and was able to achieve the mano. setting of .02-.03 but now I am not getting any movement(fluttering) on my damper, which is set at 2. I know this stuff was in the DVD and manual but I have neither, anyway I am not too concerned because I have two O2 monitors in the basement.

Bubba,
I don't want the co alarms to go off. Turn up your rheostat to a 3.5 draft. I will cost you an extra $20.00 a year in coal, but not co poisoning. BE SAFE!!!!!!!
