Hello, recently purchased a used Northstar CS550 and moved on from a conventional woodburner. Everything appears to operate as it should, the only issue I am having is getting the corn ignited. It seems to ignite slightly and smolder out. The corn is below 14% moisture and appears to be dry. When the stove room blower gets to temp and runs the fire pot just appears to fill with corn and never fully burn. Upon inspection, I have only noticed the damper in the fresh air intake seems to need more air pressure to be pulled open. Anyone have any experience with these stoves? Thanks.
