Installation The hot water heater should stand on a solid surface and be levelled with assistance from the setscrews underneath the tank. The tank models that come without setscrews can be levelled with assistance of a shim. This must be done before the tank is connected to the pipes and filled with water. Connections not in use must be plugged appropriately. During water filling, condensed water may emerge on the outside of the tank. This will result in water underneath the tank, on the floor.
Safety valve The safety valve must be inspected regularly. Ease the safety valve lever slightly to release some water through the overflow pipe. This must be carried out at least 4 times a year. It is quite normal for the safety valve to let out small amounts of water when the water tank is being charged. • • • If the valve does not work satisfactory, it must be replaced. If there is a risk of freezing, the water heater must be drained. In the event of malfunctions - contact the installer.
