COZY 12 - Technical data of the sauna stove; 1. GENERAL

1
Congratulations on your choice! The „COZY“ sauna stove works best and serves
you longest when it is used and maintained according to these instructions.
Read those instructions carefully before installing or using the sauna stove!
The first heating must be performed outside or in a well-ventilated hot room, because the
final curing of the external heat-resistant paint of the sauna stoves is completed only after
heating and the curing process may give off an unpleasant burning smell. Avoid scratching
the sauna stove before that. It’s not recommended to fill the sauna stove with stones before
the first heating.

1. GENERAL
The „COZY“ sauna stove is intended for providing dry or humid heat in a sauna.
Our product range includes various modifications of the sauna stoves. The selection has round and
angular-shaped stoves. The stove can have a hot water boiler, a glass door and a wall penetration (TW
through the wall model).
The stones of the sauna stove must be large granite fieldstones or also sauna stove stones sold in
specialised stores.
Choose the stove model carefully. A stove with too low output must be heated longer and more
intensely, which will shorten the stove’s life span. Please note that non-insulated wall and ceiling
surfaces (such as brick, glass, tile and concrete surfaces) increase the output requirement of the stove.
