Any cloggingdue to sediment or fines will adversely affect the operation of the heater.It is recommended that the heater be installed with a isolating valve whichallows it to be isolated from the mains supply for servicing.Water pressure requirements:Minimum - 0.1 bar, Maximum - 7 bar.Warning: If pressure is likely to exceed 7 bar, a pressure limiting valve must beinstalled in the cold water supply line. We recommend a valve rated at3.5 bar for this application.b) VentingA vent at the base of the heater must be plumbed to a safe visible location as,under certain conditions, it may discharge cold or boiling water and/or steam.For exposed vent plumbing, connect vent outlet from the base of heater to a15 mm OD pipe which has a continuous fall, is no more than 3 metres long,has no more than 3 right angle bends, and discharges to a waste water drain.For concealed vent plumbing, connect plumbing to the vent outlet from theheater rear using a capillary elbow protruding 45 mm from the wall.Installation Procedures ContinuedCOLDINLETVENTOUTLETINLETPOSITIONVENTPOSITION45mmElbow250mmWiringConcealedVentConcealedInlet45 mmSide ViewFront ViewExposed ventWith Tundish
