Grate riddling
To remove ash from the grate use the grate crank handle from the ash drawer
(Figure 23). To do this, push the grate crank handle onto the upper square spi-
got and turn as required. However, if the air slits of the grate are very clogged
by slag, crusts or other combustion residues, completely remove the grate and
clean it.
Adjustment of the grate
Thanks to the lifting grate the fi lling height can be adjusted as desired. The
lifting grate is adjusted by means of the grate crank handle (Figure 24). The
crank is pushed onto the lower square spigot above the ash drawer. Turning it
clockwise moves the grate upwards. Turning it anti-clockwise moves the grate
downwards.
Winter mode / Summer mode
WINTER MODE (Figure 24)
With the grate at the lowest position (full fi ring) maximum heat is supplied to
the heating system, the output is suffi cient for cooking, the output for baking
is lower.
SUMMER MODE (Figure 25)
The top position of the grate (shallow fi ring) is especially suitable for cooking
and baking with a reduced supply of heat to the heating system.
Changing between boiler and cooking operation
The control knob above the boiler thermometer is used to select boiler operati-
on or cooking operation. To do this, turn the knob to the symbol for the desired
operation (Figure 26).
BOILER OPERATION (Figure 27):
With this operating mode maximum heat is supplied to the heating system. The
heating gases are taken through a tube heat exchanger, and the radiated losses
to the room where the stove is installed (via the cooking surface or the oven)
and consequently the heat output to the room are reduced.
COOKING OPERATION (Figure 28):
For cooking and baking the heating gases are led to the cooking surface and
around the oven. The increased radiating surface area increases the heat out-
put to the room where the appliance is located. The boiler output is reduced
through exclusion of the tube heat exchanger, but not entirely stopped.
