The appliance should be connected to the gas supply by means of metal pipes --either rigid
or flexible-- having an adequate diameter (see
"Technical specifications table" at the end
of this manual). When joining pipe fittings, never use oakum or Teflon as their residues
could get to the valve and jeopardise its operation. Instead, interpose a seal gasket suitable
for use in gas systems. Do not forget to fit a shutoff valve on the gas supply line upstream
of the appliance, which should be closed whenever the appliance is not in operation. Op-
erating pressure values are shown on the rating plate and in
"Table 1: gas categories and
pressure values" above.
After connecting the appliance to the gas system, check for leaks at joints and pipe fit-
tings; to do so, use soapy water or a specific leak detector (spray).
