I acquired a Jotul 118 from an estate where it was first installed around 1976. It appears in perfect condition and was clearly just lightly used.
Internally there is a horizontal baffle between the firebox and the upper chamber. There are two hanging plates in the firebox. The floor has tall "fins" in a wavy pattern front to back. There's no brickwork inside.
The question: The fins had what looked like sand - in some areas "crusted" or caked. After cleaning it all out it occurred to me to ask if it might have been there by design? Did I make a mistake by cleaning it out?
