I put in a maxim 250 last January and it ran great until it started to get warm out. My boiler keeps over heating and it has the water protection system on it, so it soaks all the pellets in the feed system which creates a mess. My dealer does not seem to know much about this thing. I am burning a hardwood pellet. I set my water temp at 180. When the water gets to 180 the pellets stop feeding but the burn chamber is still heating the water, making the fire protection system go off at 200 degrees. Does anybody got any ideas on air setting or heat output ranges???? Thanks for your help in advance.
