My stove is the MF3800. When I burn corn I throw a handful of pellets in the burn pot before lighting. Then I run it with the thermostat off. We have had 20 below zero temps and it easily heats the house. The local thermostat only measures the temperature near the stove, so you will have to turn it up to get the desired temp in your whole house. I find my stove stays cleaner and uses less fuel with the thermostat off.

The recommended settings in the manual & on the stove are way off. I burn a corn pellet mixture which I find burns a lot hotter than just pellets. It gets cold here in northern NY and on the coldest days I burn pure corn on range 3 or 4 without the thermostat on. Adding as little as 20% corn to pellets produces much more heat. I dump my pot every day and clean out the stove every 2 weeks or so. If you call the factory they can run you through the steps to increase the output of the combustion fan.

The stove was supposed to come with a locking burn pot and I had problems with it sliding off the ignitor. The factory sent an upgraded pot to my dealer. The stove throws plenty of heat but my only complaint is that if you burn corn or a corn/pellet mixture the factory recomends you do not use the thermostat. When I looked at different stoves I definitely wanted one with the thermostat so I could leave it unattended with no worries. The burn pot does not have a stirrer so when it is in thermostat mode the corn clinkers tend to fill up the holes in the pot making it harder to ignite each time.

I have a Cumberland MF3800 stove that I have been using for about a month now. Any other owners of this stove with info on settings or advice.
