I have a Pioneer with an 8" duct top. When the feeder is running near max the temp of the stove gets to about 550-600 degrees. I'm afraid that I'm overfiring the stove. What temps are you guys getting when the stove is near full feed?
At first, I thought the problem was that my duct fan was not pulling the heat off the stove quick eneogh (425cfm fan). Even though an 8" duct is fairly small the inlet for the blower can't be bigger than a 4x4 area so that would seem to limit air flow more than the duct size (thought to self...wonder if that hole can be increased in size??).
So for a test I let the stove cool down, I reconnected the blower on the stove and capped the duct top and let the blower blow the air out like normal. Temps climbed right back up.
