I have the oppertunity to purchase a Squire wood burning insert at a very cheap price. This is located quite a distance from me and is owned by an elderly widow lady. Since I have a large amount of cut to length firewood, I would like to know what WIDTH--DEPTH---and HEIGHT the fire box is --(Inside dimensions where wood is burned). I have been unable to get these measurments. Did Squire make different size inserts? If so, I am assuming this insert is the smaller one and would like to know the measurments of this model. Maybe someone has one and will be kind enough to give me these measurments.
