I am new to this forum,my first post was a few months back(difficult install).I purchased a floor model pc-45 and from the day it was installed july2 it has been a problem.I told my dealer I was only going to be burning pellets.In october I tried to fire the machine up to see how well it worked, (the installer never lit the machine the day of the install). The machine barely worked,which I came to find out the pellet pot and pellet inlet ring were not installed.They came out and installed the burn pot and inlet ring and changed the dip switches to 1,2,7,8 in the on position.He lit the stove it seemed better so he shut it down and left.A week or so later I lit the stove,there was smoke pouring out the back,so again he came out,siliconed where the unit connects to the exhaust.Next light by me,machine squeeling like a tea kettle,fire for 5 minutes then machine and fire shut down.Installer comes out does draft reading high60,low50? Silicones the whole hopper,no more squeel.Machine running at 72 feed rate of 4 room temp.The thing only stays on for about 5 minutes a pop,nice fire,dwindles in five minutes then nothing.Distribution blower only comes on for a few minutes most of the time and sometimes not at all.Is this normal?I bought this unit because it was supposed to be pretty trouble free and would burn anything. I am burning Barefoot pellets and the dealer is now telling me it might be my pellets why the machine is acting up,and to run my machine in stove mode.Went to dealer got new bag of pellets yesterday,new room sensor and ran on stove tem..it sucked up half the hopper of pellets in a couple hours,went back to room temp.My stove burns horrible with black soot all over the bricks(I clean this thing once a week) while at the dealers I asked how often his stove was cleaned and he said it wasn't cleaned YET...My stove is FILTHY after just a week and when I pulled the exhaust outside I got about a cup of black soot...he said it wont start a fire the chimney sweep will take care of all the soot..it been running a month and black already,when am i going to have to get the exhaust cleaned? Every month? I paid a fortune for this thing and it isnt even keeping my house warm.I have a VERY small row home in Philadelphia.My temps in the upstairs are at 58 degrees? Shouldn't there be some fire there other than on ignition? I go from large fire upon ignition to nothing in the span of 5 minutes? Isn't there a low fire present to keep the ignitor from working overtime? Please help,I am really disgusted at this point with this machine and the Dealer,Lisa
