7.2 METERS
A new gas meter will be connected to the service pipe by the local gas distributor contractor. An existing gas meter should be
checked, preferably by the gas distributor, to ensure that it is adequate to deal with the rate of gas supply required.
7.3 GAS SUPPLY PIPES
Supply pipes must be fitted in accordance with IGE/UP/2. Pipework from the meter to the equipment must be of adequate size.
The complete installation must be purged and tested as described in IGE/UP/1. Refer to Section 15: LPG FUEL for information
on LPG pipework installation guidance.
7.4 BOOSTED GAS SUPPLIES
Where it is necessary to employ a gas pressure booster, the controls must include a low-pressure cut-off switch at the booster
inlet. The local gas distributor must be consulted before a gas pressure booster is fitted.
7.5 PLANT-ROOM CONTROL VALVE
A manual valve for plant-room isolation must be fitted in the gas supply line. It must be clearly identified and readily accessible
for operation, preferably by an exit.
7.6 EQUIPMENT GAS SYSTEM LEAK CHECK
An approved gas inlet appliance isolating valve and union should be installed for each unit in a convenient and safe position and
be clearly marked. Ensure that the gas inlet appliance isolating valve is in the OFF position. Although the equipment receives a
gas leak check and gas train component integrity check prior to leaving the factory, transit and installation may cause disturbance
to unions, fittings and components. During commissioning a further test for tightness should be carried out on the equipment gas
pipework and components.
Care must be taken not to allow leak detection fluid on or near any electrical parts or connections.
