Heating of the Sauna When the heater is switched on for the first time, both theheaterandtherocksemitsmell.Toremovethesmell, the sauna room needs to be efficiently ventilated. The purpose of the heater is to raise the temperature of the sauna room and the sauna rocks to the required bathing temperature. If the heater output is suitable for the sauna room, it will take about an hour for a properly insulated sauna to reach that temperature. See item 2.1., .Insulation and wall materials of the Saun

• the moisture protection consists of e.g. aluminium paper with tightly taped edges. The paper must be fitted so that the glossy side is towards the inside of the sauna. • there is a 3/8" (10 mm) vent gap between the moisture protection and panel boards (recommendation). • the inside is covered by 1/2" – 5/8" (12.16 mm) thick panelling. • there is a vent gap of a few millimetres at the top of the wall covering at the edge of the ceiling panelling. When aiming at a reasonable heater output, it ma

There may be some circumstances where the use of short lengths of duct may not create sufficient pressure drop to achieve the desired temperature rise. This may also be the case of using the unit without a duct. This insufficient static pressure drop may result in high air flow, with the maximum temperature rise below the desired level, (even after the fan speed has been reduced to the minimum rpm). An accessory AD16, adjustable damper, is available and can be attached to the heater to produce a
