Equipment Gas System Leak Check; Flue System - Lochinvar EcoShield SHW60-325CE Installation, Commissioning And Maintenance Instructions

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.
