Drilled 1/4" hole in the stack between the stove and the baro damper and inserted a piece of brake line. I hooked the red striped tube into the brake line with a fitting and the other end into the low port on my Dwyer. I hooked the white stripe into the high port and left the other end open. I've got it adjusted to read roughly .04. My baro damper is open about 2" and the powervent is set at 45 degrees. The gentleman at Alaska said my baro damper should be open roughly 3/4" or about the width of my index finger if I was setting it up without a manometer. My question....should I adjust the the powervent angle then the damper so it is roughly 3/4" open until I get a reading of .04 or should I just leave it as is? I am unfamiliar with this stuff, so is a .04 reading sufficient enough the way it is or should I be concerned that the baro damper is open so wide? Thanks for any assistance you may provide!
I'm a little confused here. Normally a power vent comes with a rheostat to increase or decrease the motor speed which would increase or decrease the draft.
You would turn the rheostat to get your manometer reading .04 and the baro just slightly opening. Maybe that 3/4" you mentioned would be the proper setting.
Now if there is no method to change the fan speed, there should be a shutter or piece of metal which could be moved over the intake opening to vary the amount of air being sucked through the power vent. This shutter would have to be moved to reach that poiunt where the baro slightly opens at .04.
You would keep an eye on the manometer reading to maintain that reading. Either turning the rheostat to change the speed or move the shutter again to match the .04 reading while the baro is just slightly opening.
