The exhaust gases reach very high temperatures.
Flues must be hermetically sealed. Use materials that are
thermally stable at temperatures of up to 400º.
3.6.6
INSTRUCTIONS D’UTILISATION
•
The flue gas may have high temperatures, so that the exhaust gas and hot metal parts can
cause burns.
•
Do not place combustible materials on the apparatus; fire hazard.

WATER CONNECTION
Only connect drinking water to the
appliance.
Connect the appliance to the mains water
supply at the points indicated (Fig. 11),
using the hose supplied.
The pressure of the incoming water
should be between 200 and 400 kPa (2-4
kg/mm
2
). We recommend 250 kPa.
.
The water used should have the following properties:
pH:
6,5 - 7,5
Water hardness:
5 - 10 º fH ((French degrees)
Impurities:
Ø < 0,08 mm
7 - 14 ºeH (English degrees)
Chlorides:
máx. 150 mg/l
9 - 18 ºdH (German degrees)
Cl:
0,2 - 0,5 mg/l
Conductivity:
400
– 1.000 µS/cm
Recommended filters:
A) Fine filter.
If the water contains impurities such as sand, iron particles or floating substances, we recommend
the use of a fine filter at the water input.
B) Activated carbon filter.
If the water has a high chlorine content over 0.2 mg/l (ppm) (this information can be obtained from
the relevant water board), an activated carbon filter should be installed.
C) Installation of osmosis recirculation.
When the chloride concentration is above 150 mg/l (ppm) (this information can be obtained from the
relevant water board), an osmosis recirculation installation should be mounted. In this case, please
remember that the minimum conductivity value is 400 µS/cm.
D) Water descaling:
For water with a high level of limescale (without chloride load) the water should be treated. Systems:
H+. Interchange of ions or Kleensteam. We strongly advise against the use of sodium exchangers
(normally used in dish washers) due to the formation of sodium sediment and the delay in boiling
with common salt.
For the selection of the filter systems (A, B, C, D), it is recommended the manufacturer BRITTA.
