for the technician
Gas connection
Boiler installation must be carried out from a qualified technician, [as indicated by the Law XXXXX]
because an incorrect installation can cause damages to people, animals or things, for which the
manufacturer cannot be held responsible.
Verify what follows:
a) cleaning of all system gas pipes in order to avoid the presence of residual combustion products
that could compromise the correct boiler functioning;
b) gas line and ramp conformity with laws and rules actually in force (Laws UNI-CIG 7129/01 and
7131/99 – DM 12/04/96);
c) internal and external tightness of the gas system and connections;
d) supply pipe must have a section greater than or equal to the boiler one;
e) supply gas must correspond to the one for which the boiler has been regulated; otherwise, call
[an HERMANN Servicing Centre] [a qualified technician] for gas conversion;
f) an interception valve must be installed upstream the appliance;
Open the meter valve and purge the air that is inside the system pipes (including all the appliances).
While connecting gas inlet pipe of the boiler to the pipe coming from gas network, it is
MANDATORY to insert a TIGHT GASKET, whose dimensions and material must be
adequate. Connection is NOT suitable for hemp, teflon strip or similar materials.
Using LPG, it is absolutely necessary to install a pressure reducer upstream the boiler.
Due to various installation possibilities, the gas cock supplied with Standard Connections Kit for
SUPERMASTER boilers has a simple male Ø ½” connection, facing the rear of the boiler. No gas
pipes are supplied.
