Heating of the sauna
Malfunctions
Always check the sauna room before switching the sauna heater on (make
sure that there is nothing near the heater). When you are using the heater for
the first time, the heater and the stones may emit smells. Make sure that the
sauna room has been efficiently ventilated. If the output of the heater is
proper it will take about an hour to reach suitable temperature (Fig. 7). The
temperature in sauna room should be between +60 - + 90 °C, according to
the preference of the user. Too powerful heater will heat the sauna room too
quickly and the stones won't have enough time to warm. Because of this the
water thrown on the stones will run through. If the heater is underpowered the
heating time will be much longer.
If heater doesn't work, check the following:
- Check the instructions for the separate control unit
Insulation
The sauna must have proper insulation on the walls, ceiling and door. One
square meter (m²) of un-insulated surface increases the cubic volume by
approximately 1.2m³ when determining the power requirement of the heater.
Refer to page 12 (Technical Diagram).
Ensure that moisture proofing is appropriate in the sauna room. The purpose
of this is to prevent spreading of moisture to the other rooms or wall
structure. Moisture proofing must be placed between heating insulation and
panel.
Thermal and moisture proofing need to be installed according to the following
order from outside to inside.
The recommended minimum thickness of the thermal
insulation in the walls is 50 mm and in the ceiling 100 mm.
It is possible to use carton- or aluminum foil laminate as a
vapor barrier, which is affixed over the insulation aluminum
foil inwards.
Leave at least 20 mm air slot between vapor barrier and
inside panel
To prevent gathering of the moisture behind the panel, leave
the slot between wall panel and ceiling.
