Page 15: For The Installer
2. FOR THE INSTALLER 2.1.2 Water connections A.O. Smith water heaters are suitable for connection to If possible, use a trolley or fork-lift truck to transport the vented, unvented and pumped pressurised systems. In heater. The heater must be vertical at all times during each case appropriate valves and fittings should be used transportation. -
Page 16: Vented Systems
2.1.2.1 Vented systems If the water heater is to be connected to a cold feed tank or cistern the hot water supply pipe must include an open vent which discharges over the cold feed cistern. The cold feed cistern must have an actual capacity of greater volume than the hourly recovery rate of the water heater(s) which it supplies.The minimum actual capacity is 50 gallons or 227 litres (see figure 3). -
Page 17: Unvented Systems
2.1.2.2 Unvented systems To install an A.O. Smith water heater on an unvented cold water supply system a kit of valves and fittings listed by the water research centre and complying with part G3 of the current building regulations and BS 7206 should be used. - Page 18 A.O. Smith water heaters are tested to a maximum pressure of 12 bar and a maximum working pressure of 8 bar. Dead legs on a hot water installation are undesireable. Where possible they should be avoided. Where the inclusion on the system of a dead leg is unavoidable the following restrictions should be applied: For pipes not exceeding 19 mm.

Page 21: Descaling
Descaling Calcium deposition depends on the type of water and the demand. In addition, calcium deposition increases at high water temperatures. A temperature setting of 60°C is recommended, which will keep calcium deposition to a minimum. Access covers are located on the right and left sides for inspecting and descaling the tank. -
