Review: Osburn 1100
This insert was a replacement. The firebox is the size of a large glove box. It requires very small pieces that burn up quickly. The top firebox aerator tubes and angle iron came loose and fell into the firebox. The blower will not turn on until the insert is glowing hot due to a temp. control fan, It can take 20 minutes of leaving the door partly open - feeding it fuel before the fan kicks in. It is also so small the ash needs cleaned out every four days. The fan blows up toward the ceiling so it only heats one room, not a 1,400 home. I is a pox. Do not buy this insert.
