Installation and Operating Instructions Klapi
Light protective material
Safety distances to inflammable materials may be reduced to a half by using a single layer of light
protective material and to a quarter by using a double layer.
A single layer of light protective material (1x) can consist of a non-flammable, fibre-reinforced cement
board (e.g. Minerit board) with thickness of at least 7 mm or a metal plate with thickness of at least 1
mm.
A double layer of light protective material (2x) can be made by using two boards of the above-
mentioned materials. The fastening points must be sufficiently close to each other in order to ensure a
stable structure.
Leave a gap of a minimum of 30 mm between the surface to be protected and the board(s). The light
protective material should extend at least 600 mm above the heater.
A single layer of light protective material equals to brickwork of at least 55 mm thick. A double layer of
light protective material equals to brickwork of at least 110 mm thick.
The brickwork must be open on the sides, and the distance to the surface being protected must be a
minimum of 30 mm.
Heater installation
The adjustable feet of the heater allow you to install the heater directly and firmly even on an inclined
floor surface. The adjustment range is 0–30 mm. Leave a generous gap between the heater and the
floor.
Screw the adjustable feet downwards so that you can rotate them with an open-end wrench, for
example, when the heater is in place.
NOTE! The adjustable feet may scratch the surface of the floor if the heater is moved on the floor.
