My PF100 forced air pellet furnace had to be located towards the opposite end of the main duct from my oil furnace. I'm curious if the other pellet furnace owners adjust their duct registers when switching from one furnace to the other. I tweak the registers on each end of the main duct. The difference is usually only 1 or 2 degrees between rooms; but when I adjust them all the rooms in the house stay the same. My kids call me a nit-picker so that could be the main issue.
