3.4.3. WATER CONNECTION
Between the water system and the appliance you have to put a tap.
The appliance is equipped with a 3/4’’ male thread and of a mechanic filter. The appliance is equipped with a connection wat
er set:
you have to use only this for oven’s water connection!
You have to screw the female thread of the t
ube to the mechanic filter of ¾’’.
Before installing the alimentation tube is recommended to let flow running water to clean impurities and dust.
Characteristics of water:
- it is recommended a pressure less than 200 kPa for the enter of water.
-
for greater pressures, install a pressure regulator calibrated at 200 kPa.
- water max temperature= 30° C
-
maximum hardness:
5°F (to avoid calcium deposits, which are harmful for the equipment).
- it is recommended the installation of a water softener to avoid the formation of mineral depots.
OPERATION TO PERFORM DURING THE INSTALLATION PHASE TO THE WATER NETWORK: After performing the
installation to the water network, it is compulsory to run a washing set up, as described in paragraph WASHING SYSTEM.
3.4.4. GAS CONNECTION
The section of the enter gas tube depends on the gas type and on the consumption of the installed oven. The connection must be
done according to the current local regulations. The ga
s oven is equipped with a ½’’
male thread positioned in the back side of the
oven (see the drawing below).
The connection has to be done with fitting adapters and gaskets appropriate for the used gas type (see technical data).
A fast acting shutoff valve must be installed on the gas inlet line to the oven. The valve must be type test approved according to the
current regulations. The connections of the gas main can be permanent or detachable; if flexible metal tube is used, this should be
made of stainless and corrosion resistant material (do not use rubber hose!). Every type of chosen sealing material used for
connections have to be tested and approved for this purpose. All connections between the mains and the appliance must be tested
for leakage. The recommended method is to use a proprietary leak detection spray or a non-corrosive foamy liquid of any general
description can simply be brushed onto the fittings: the important thing is that NO BUBBLES SHOULD APPEAR. WARNING: NEVER
ANY CIRCUMSTANCES TEST FOR GAS LEAKS WITH A NAKED FLAME.
3.4.5. DRAINING WATER AND STEAM EMISSION
Water
The water is drained through a pipe made of a heat resistance material. The temperature of the draining water is about 90°C. It must
be positioned in the back side of the oven and connect to a siphoned drain through a rigid or flexible pipe. The diameter of the pipe
will be 32 mm and length 1,00 mt without elbows or narrow passagings and in order to an easy drainage it is recommended
installing 20 cm under the draining connection.
Vents
Vents are positioned on the top of the oven
: don’t block, shut or duct into other pipes.
Kept a distance between the vents and
materials or furniture which could be damaged. Gas oven may be positioned under a suction hood or under a ducted ceiling suitable
for gas.
