·Temperature and Pressure Relief Valves should be installed on the top of the water heater top or side. The Temperature sensing element must be immersed in the water within the top 6″of the tank.
·The eliminating pipeline should be installed under the relief valve. Its terminal station distance in floor drain should be greater than 6″to make it easily remove and observe water.
• Install drain piping to avoid contamination of the tank surface.Drain pipe should be connected to floor drain or collector.
• When connecting the drain pipe, make sure that we can observe the drain.The drain pipe should be well protected against freezing and leakage, keep it clear and prevent blockage.
• A water pressure rregulator valve must be installed in the hot water system to prevent sudden increase in water pressure and affect the normal operation of the safety valve.
• Periodic inspection,the safety valve handle is swayed at least once a year, water leaves the handle and back to its original position,no water to indicate that the valve is invalid,it should be replaced immediately.
• Dirt will directly affect the operation of the valve, please use a clean water supply.Hard water areas need to increase the number of regular inspections.
Direct Installed on the Top Direct Installed in the Side
·After installing water heater the users must lift the relief valve handle once at least every year, so as to ensure that unblocked things in the waterway of the relief valve.
·Before operating handles, please check the elimination pipeline which joining the relief valve, guaranteed that the hot water from the relief valve discharge the proper place, otherwise it may cause the bodily injury.
·If the handle is lifted, without water flowing out, it proves that the relief valve is invalid. Then it should turn off the water heater immediately and check the valve.
