JRGARANT Safety Valves JRGARANT safety valves JRG Code 1025 and Water heater 1028 protect water heaters (closed design) from pressure-related overload. Water Max. Outlet volume heat GN safety Outlet Function output Litres kW valve pipe When heating water, its volume expands, which causes pressure to increase in a closed system. The backflow up to 200 75 ½" ½“ preventer installed in the supply line prevents the water from flowing back from the water heater into the piping 200–1‘000 150 ¾“ ¾“ system. The safety valve opens as soon as the set-to-operate 1‘000–5‘000 250 1“ 1“ pressure is reached and the water volume that caused the overpressure is discharged. Set-to-operate pressure of JRGARANT safety valves Installation Safety valves JRG Code 1025 are factory-set at 600 kPa (6 bar) The safety valve must be installed vertically and easily and must not be modified. accessible. No shut-off valve may be installed between safety valve and water heater. On request, factory-set pressures of 100 – 1,000 kPa (1 – 10 bar) Surplus water is to be drained using a visible and free outlet can be supplied under JRG code 1028. Please specify the through the shortest possible pipe into a sufficiently desired set-to-operate pressure when placing your order. dimensioned drainage pipe (see „nomogram discharge capacity – vent position“). Application JRGARANT safety valves are approved for the following In order to ensure smooth operation, we recommend using parameters water-drip nozzles JRG Code 8225 and 8228. Thoroughly rinse the supply pipe before commissioning the Water temperature: Max. 95 °C safety valve. Pressure: Max. 1000 kPa (10 bar) During the heating phase of the water heater, water must leak from the safety valve outlet (expansion). (Paragraphs 5.3 and 9 of SN EN 1491, as well as paragraph The drainage pipe or the nozzle of the safety valve must not 6.4.2 of W3, SVGW edition 2013) be closed. 4
