Hi, I have a Vermont castings encore 0028 that I recently rebuilt.  New gaskets, lower firewall, upper fire wall, refactory assembly, and a new condar catalytic combustor.  I have read both the owners and service manuals from front to back and I'm positive I rebuilt the stove properly.  On my first burn everything work great.  Stove was brought up to 500+ degrees and I engaged the by-pass.  I quickly noticed the temperature continue to rise which tells me the combustor was doing it's job.  I then lowered the thermostat all the way and continued to burn at 550-650 degrees for the next 5-6 hours.  Fast forward to my next burn.  Did everything the same as my first burn and when I engaged the by-pass at 500+ degrees I noticed the temperature started going down.  I have had an addition 2-3 fires and still can't get the combustor to work properly.  At best, when I've been burning for an hour + and engage the by-pass the temp will stay the same, but never go up.  Any suggest would be greatly appreciated.
