2. Preparing for sauna heater installation

Check the following before installing the sauna heater.
- The ratio of the heater's input (kW) and the sauna room's volume (m
in Tables 1 and page 5. The minimum and maximum volumes must not be exceeded.
- The height of the sauna room must be at least 1900 mm or 2100 mm depending on the heater power. See tables 1.
- Uninsulated and masonry stone walls extend the preheating time. Each square metre of plastered ceiling or wall
3
surface adds 1.2 m to the sauna room's volume.
- Check page 6 and 7 Table 2 for a suitable fuse size (A) and the correct diameter of the power supply cable
(mm²) for the sauna heater in question.
- Conform to the specified safe clearance around the sauna heater.
- There should be enough room around the control panel for maintenance purposes. Also a doorway can be
considered as a maintenance area.

2.1 Installation

These sauna heater models are installed freestanding and fixed on the floor from two legs with cotter bolts.
When fixing the sauna heater, adhere to the minimum distances from flammable surfaces as specified in the sauna
heater's rating plate table 1 and figure 1 and 2. The walls behind the sauna heater or the ceiling must not be clad with
fibre concrete board, for example, because it may result in an excessive rise in temperature of the wall material. The
sauna heater must not be installed in a recess or surrounded by enclosed covering. Wooden panels can be used as wall
and ceiling material.
A single sauna heater is allowed per sauna room.
Installing the sensor near a supply air vent
The sauna room air should be exchanged six times in an
hour. The diameter of the supply air pipe should be
between 50 and 100 mm.
A circular air supply vent (360°) must be
installed at least 1000 mm away from the sensor.
An air supply vent with a flow-directing panel
(180°) must be installed at least 500 mm away from
the sensor. Air flow must be directed away from the
sensor.
Ceiling installation of the sensor
In ceiling installation, a 5-mm hole must be drilled to the
sensor case to allow any condensed water to drain.
Do not spray water directly towards the sensor or splash
water at it with a sauna scoop.
