1.2. Considerations and instructions

Check the suitability of the heater for the sauna, refer to the maximum and minimum cubic volumes. Table 1
Due to stone and glass walls, 1.5 m
stone and glass wall.
In saunas with timber walls, 25% is added to the calculated volume.
In order to avoid damages during transport, the heater must be transported in an upright position.
All advertising labels and packaging material must be removed before the sauna heater is used.
BURN IN THE HEATER OUTDOORS BEFORE INSTALLING IN THE SAUNA.
In addition to these instructions, all local regulations must be followed, including those referring to local and European
standards. They must be complied with when installing the fire chamber.
You must also find out about any necessary building planning permissions and the floor load capacity before installing the
heater.
Before installing the chimney, you must also check the chimney's temperature class.
•
Average temperature of combustion gas on nominal output. Table 2
•
Maximum temperature of combustion gas in safety test. Table 2
•
Temperature classification for the chimney is T-600
Check the following issues and choose the location for the heater accordingly:
•
Safety distances to flammable and non-flammable structures
•
Location of the chimney connection (the height of the old chimney connection, if any, from the floor, or installation route
for a new chimney)
•
Floor material (flammable, non-flammable, tiled, waterproofed).
If the heater will be connected to a divided chimney (another stove has already been connected to the chimney), each
connection must have its own damper. The chimney must be sized in line with the larger stove.
Before beginning heating, also make sure that the smoke flue draft is sufficient and that the heater is not damaged.
•
Draft in the chimney is -12Pa on nominal output.
•
Draft can be roughly checked for example by burning a bit of newsprint in the heater.
•
Before starting a fire in the heater, switch off any device that might create a vacuum, such as an extractor fan or a
forced ventilation system. If the forced ventilation system is equipped with a fireplace switch, use it following the
instructions supplied with the system.
•
If the heater has its own external delivery pipe for combustion air, make sure it is open and that there are no items
causing a blockage in front of it and that there is a supply of air. The delivery pipe can be located down by the heater
on the wall or floor. It must be equipped with a grille which can be closed or something similar. The minimum pipe
diameter is 10 cm.
•
Kastor heaters are meant to be used for heating a sauna. They must not be used for any other purpose.
•
The heater is not meant for continuous 24 hour use.
