I wanted to know if anyone had a problem with their glass window? Do you have problem getin it started? How often do you have to clean it? Mine uses biger wood then other ,warms my homw up quicker,yet I dont hear it going as I did the other. It smokes alot too-with dampers wide open or closed. Button on top I guess for blower-which when runin makes my meter go haywire. I keep bottom damper open more to let air in to keep going.How much would buyin new glass be & where to purchaseit??
