NB! The air tunnel should not be fi lled with stones!
NB! Make sure that the air tunnel and the upper ends of the heaters are not
visible between the stones. Otherwise, the safety distances given in Table
1 do not apply, as additional heat radiation occurs on fl ammable surfaces.
• Check the condition of the stones once a year to remove broken pieces and
replace them, if necessary.
ATTENTION! TOO SPARSELY FILLED STONE CONTAINER CAUSES FIRE HAZARD!
1. Partially fi lled
2. Correctly laid stones
Opening the ribs of the heater
To simplify the installation of the stones, all the ribs of the heater can be removed by
using wooden blocks (A). See Figure 3.
1. At the base of the heater, loosen the threaded bar nuts by 5 mm.
2. Push the wooden blocks between the ribs of the heater.
3. The rib is released from both sides.
4. Carefully remove the rib from the joint fi rst from the right end and then from the
left end.
5. In the same way, you can immediately remove the rib located below the removed rib.
NB! Pull the rib straight away from the heater without twisting or using force to
avoid bending the pins!
When putt ing the ribs back, do everything in the reverse order.
The rib should be att ached to the joint fi rst from the left end and then from the right end.
