6.4.1 GAS VALVE
The boilers are equipped standard with the
SIT 845 SIGMA gas valve (fig. 18).
The gas valve is set at two pressure values:
maximum and minimum.
According to the type of gas burnt, these
correspond to the values given in
Table 4 .
The gas pressures at the maximum and
minimum values, are factory set. Conse-
quently they must not be altered.
Only when you switch the appliance from
one type of gas suppl y (Natural gas ) t o
another (LPG), it is permitted to alter the
the operating pressure.
6.4.2 GAS CONVERSION
This operation must be performed by
authorised personnel using original Sime
components.
To convert from natural gas to LPG or vice
versa, perform the following operations (fig.
19):
– Close the gas cock.
– Disassemble the burner manifold (3).
– Replace the main nozzles (6) supplied in
a kit, inserting the copper washer (4).
Use a ø 7 spanner to perform this ope-
ration.
– Configure the new fuel as indicated in
point 4.2.1
– For calibrating the maximum and mini-
mum gas pressure values, see point
4.2.2.
– After have ultimated the conversion of
the boiler, please stick onto the casing
panel the plate showing the relevant fee-
ding gas which is included into the kit.
NOTE: When reassembling components
which you have removed, replace gas
seals; test all gas connections after
assembly using soapy water or a product
made specifically for the purpose, being
sure not to use open flame.
