Gas installation

DANGER
Risk of explosion in case of gas leakage due to improper instal-
lation! Only authorised installation companies (VIU) under con-
tract to the gas supply companies (GVU) are permitted.
 The installation companies authorised for installing or modify-
ing gas plants must provide the following details to the gas
supply company before starting installation work:
– Type and scope of the proposed plant.
– Proposed construction measures.
 The contracted installation company shall confirm with the
gas supply company that there will be adequate gas supply to
the plant.
 Gas supply pipe requirements:
– The pipes should be short and straight, as far as possible.
– It should have a nominal width greater than the nominal width
of the burner fittings.
– It should have corrosion protection.
 For pipes inside the building and in the open, it is recommend-
ed to do a preliminary and main test with air or inert gas (not
oxygen):
– Preliminary testing: Without fittings, with an excess pressure
of 0.1 MPa.
– Main testing: Entire pipe plant from the main cock to the stop-
valve at the burner with closed solenoid valves and an oper-
ating pressure of 1.1 times and a minimum excess pressure
of 0.005 MPa (50 mbar).
