Update.....
The tech came out two weeks ago, looked over the stove install..... said it was great, nothing wrong with the venting / install.
Looked the stove over, he asked if there was a baffle plate to cover the heat tubes, I said no, this stove does not have them. The plates / ash traps to the left and right of the heat tubes inside the firebox had warped, a sign of over fire.
Fired up the stove, checked the startup, so far so good. As soon as the stove came out of it's startup, he noticed the burn was not right and could see that the fire was like a forge. Exhaust motor spinning too fast ? Maybe.
I asked the tech if the over fire was a cause for the firebrick behind the pot to disintegrate like it has, he said yes, if the burn is too hot it will.
He checked the timing of all the feed rates 1 - 5 for the auger.
1 and 2 was spot on with the timings in the manual, but still had that forge like burn.
3 - 5 was off ........ the on timings was correct for the fuel feed (on), but the off timing was out (short) should have been 3 seconds off as per the manual, timing the tech got was 1.5 / 2 seconds off and not 3 seconds, based on that the stove is over feeding fuel. Still had that forge like burn.
The next day I get a call from US Stove, they said that a new stove was going to be sent to me, sweet, I asked if I could have the pedestal version, sure they said, not a problem.
Friday, last week, new stove arrives. Installed it the same day, so far so good, no problems at the moment.
Stove is burning different too, not getting that forge looking burn in the pot like I did with the other stove. Also, the air damper on the new stove seems to work better, I can see a more noticeable change in the flame height / brightness when adjustments are made, I did not have this effect with the other stove, it made little change when adjustments where made.
Did a 'glow' test, heat settings 3, 4 and 5, pot still glows red, so I will keep watch on this and see what happens.
Again, US Stove's customer service has been great, they have bent over backwards to service me and sort out my stove problem(s).
I hope that this new replacement stove holds up, and no other problems arise.
