    Question about the readings and weather or what ever. The reason I am asking is the week after I installed my stove, I purchased a gauge, after the stove was running on high for an hour, I set the the intake to the specs for the stove. Two weeks later, I check the stove again and the reading is quite a bit lower. Stove was set at .11 to .12 and the new reading was at about .08.

    Didn't include my queastion. Does anything affect the reading, or should it remain consistant.

    Nah, clean as a whisle. The change was within three weeks of being installed. With the pellet testing, it was being cleaned out every day or twop and every weekend shut down and vacuumed.

    The stove is installed with a 5 ft rise inside into a 4 inch flex liner up 15 ft to a cap.

    You cleaned the hole venting each time?

    Three weeks shouldn't require that kind of cleaning. The stove is brand new put in on November 12th.

    Also, do you have a link to the gauge you used? I wouldn't be surprised if .02 is within the accuracy of the instument.

    How many bags? And it very well could change the reading. .02 is very little change in pressure.

    The change occurred over about 12 to 15 bags.

    I would think that is plenty enough to change the pressure. On one of my stoves, you double those numbers and it needs a full cleaning because you can see the changes in burn pattern.
    .03 is very little pressure change. So much so I question the ability to actually adjust stoves with any confidence unless it can be done by changing voltage via the controller. Any manual damper adjustment I wouldn't personally rely on except for a ball park.

    The ones in the picture? Ballast Point Sculpin is one of my favorites. I'm a hop head, working on a pellet head. The other one is really interesting. Its a double IPA fermented with brettanomyces, a little funky, then added blood oranges. Really nice sipping beer.

    When you first set it up did you let it rip for at least an hour before setting draft? My first attemp I didn't think it mattered, But when I checked it a few weeks later on a long burn it was lower than what it was on initial start. My Omega has a range 0.12 to 0.15 on high. After a good long burn I set it to 0.13 1/2 and its been pretty steady since.

    I'd check the cap(screen) JIC. If it starts to get even a little build up it might effect draft.

    FWIW, I have gone to a digital meter, easier to use, a higher range (the model shown only goes up to -.5 ".......this number can "peg" in some cases, never giving you a true draft reading......)

    Digital is nice and lots of choices but the manual ones are good to leave on the unit if needed;)
