On my new (floor model) Monia 2.0, something seems to be wrong with automatic grate cleaning (Message “Cleaning Grate”). This is my theory. This stove is 1 1/2 months since installation, I have seen “Cleaning Grate” only once. We always run on p3, 66-68 degrees. Sudden, loud increase in exhaust fan RPM, for 2-3 seconds, frequently and irregularly (I’m assuming it’s the exhaust fan) at least 10 times a day. Never “Cleaning Grate” message.

We clean grate, ash tray, glass, etc. daily, vacuum out all ashes and so on. Combustion chamber every 2 weeks. Quite a bit of incrustation in grate a couple times, had to take the buildup out with ice pick and woodworking chisel.

This all makes me think the problem is self-cleaning of grate. When installed, no cold test was run by technician, no instructions of panel functions, and so on. I probably should have run away. I’m thinking I should set the stove back to factory settings, take it from there. I suspect someone messed with settings before I bought it. I don’t feel competent to alter settings more than this yet.
