Big Beam and I are running.
A close friend has the 1557, we set it up last year as well, he burns wood for the most part. It took time to get the disc adjusted. Part of what we found is we were pulling cold air off the basement floor and cooling the disc rapidly shutting down the fan . We directed supply air towards the return air fans. This helped until the basement got heated up.
Hope this helps.
Big Beam is right with:
"The secret to these furnaces is PATIENCE,They're finicky but when you learn what they like they make a lot of heat with great burn times."
