Moulded fire clay
If the Fera is built into a moulded fire clay mantle, there is no need to
use a convection set. This is a material which is highly suitable for
converting the appliance heat into healthy and comfortable radiant
heat. This material absorbs heat on the inside and gives off the stored
heat on the outside, into the room. The fibre-free insulation plates,
with a maximum permitted temperature of 1,100°C, are heat-
insulating and fireproof, and weigh 0.38 kg / dm³.

Mounting of the fire clay
The mounting of the fire clay is not included in this manual. Kal-fire
runs courses on this.

3.1.1
Lighting the burners
Make sure the gas tap is turned on. The main burner in the fire is
ignited by a pilot light, which in turn is ignited by a piezo element.
Once the pilot light is lit, it heats up a thermocouple which creates a
small flow. This flow holds the gas valve open. Should the pilot light
go out, no gas can keep flowing. This means you can be sure of safety
at all times. The ignition takes place as follows: (see Drawing 11).
Turn the ignition knob (1 in the above figure) to the “pilot light”
position (small flame) and press in. Gas will now flow to the pilot light.
Keep the knob pressed in, and turn it to the left, “
” position; you will
now hear the piezo ignition clicking and see a spark jump over to the
pilot light; keep this knob pressed in until the pilot light is burning
steadily. (This can take longer straight after mounting because the
gas pipe still has to fill with gas).
When the pilot light is burning, keep the knob (1) pressed in for
approximately another 20 seconds, otherwise repeat the above
operation.
