    Well it looks like I need to practice what I preach more often.

    I took out a Meridian that work great in my showroom to install as a demo. Connected in up at the persons house works great

    then back out my store in the same spot connected a brand NEW made this year Meridian in the same place.
    It is burning like crap. the stove soots up black in 2 hours.
    I can only get .10 PAS on my magnahilic with the Air control All the way out. Need about .12 and you normally get that with the air half way out.
    I check the door GOOD
    Checked the Ash pan door GOOD
    Check the burnpot GOOD
    Decided to start over and test all the Voltage and Amp reading on the stove
    I spend 2 hours this morning before the store opened to figure this out.
    I had a Meter connected right on the board on the Common and Hot wires on the Molex plug
    Had another Amp meter on the Hot wire right at the blower.
    had my Magnahilic connected to the stove.
    Ran the stove
    Recorded all Reading at different times of start up cycle and then each feed rate
    All were good
    the Pressure was still low.
    Took the ash pan off again LOOKED at the gasket GOOD
    Pushed as hard as I could with my foot against the ash pan to see if the pressure changes
    NO change
    Check the door gasket
    Pushed on door hard on the sides and the front
    NO change in pressure

    Let me go look at the T clean out.
    keep in mind the other Meridian stove worked GREAT with the same venting just 2 days earlier.

    Pulled off the T cap
    it had just a little bit of ash in the cap but it was cool at the bottom.
    Banged on the pipe.
    A 3" ball of White Clump of what could have been a Rats Nest in the pipe fell out of the T clean out.

    Shut down the stove
    Pull it out away from the wall
    Run a brush out the horizontal pipe out the wall
    Run up to the roof.
    Clean the pipe from the roof down.

    Hooked it back up
    Start stove

    WORKS like a meridian
    HOT and clean.
    .13 WCI with the damper at 1/2 way out.

    Now I tell people over and over to clean the pipe and pull the blower
    Every time they say the stove is burning like crap
    I did not listen to myself the first time.

    Over confidence...why those jet pilots used the wrong (short) runway in Lexington last year!

    It is so easy to skip a step...when you "know" better.

    What do the Buddhists say? "Approach all situations with a beginners mind".

    LMAO!! i know how ya feel bro, had a bird nest in my flue after a summer once , didnt check it , figured aint nothin in there and it was swept in the spring and not used after, smoked up the house a bit , jumped on the roof and immediately spotted where the screen was bent back . cant believe a bird would have bent back the screen that way , but there was a nest , , dragged it out and the stove immediatly took off again. wife , watching the stove from inside yelled "what did you do???" i said come outside, and when she did i dropped the bird nest in front of her. since then i always visually inspect my flue before the first fire. even left a note in my stove for a couple years to remind myself.

    We took the Firebrick out and found more
    The Mouse Decided to make a home in the stove behind the firebrick
    It pulled at the KOAWOOL out from the back brick and stuff it in the exhaust passages.
    I will post photos Later.

    Should have seen me start the snowmobile first time last month. Mice come piling from out of everywhere under the engine. First 3 then about 5 more. They kept running back trying to hop onto the sled and climb back into the motor till I got it out of the area and then a couple more spilled out and kept trying to do the same thing. You have to watch the little vermin with stored machines. They build a nest on the aircleaner ( one of their favorite spots) and then you start it and run it and fry the engine. A guy I know killed his almost new riding lawn tractor like that once. Damned mice, where are the cats when you need em??
