INSTALLATION THIS WATER HEATER IS NOT SUITABLE FOR POOL HEATING The installation must comply with the requirements of AS/NZS 3500.4, AS/NZS 3000 and all local codes and regulatory authority requirements. In New Zealand, the installation must conform with the New Zealand Building Code. All packaging materials must be removed from the water heater prior to its installation. - Page 19 INSTALLATION Remember all local authorities have regulations about putting water heaters into roof spaces. SAFE TRAY It is a requirement of AS/NZS 3500.4 that for a new installation, a water heater be installed in a safe tray where in the event of a leak, property may otherwise be damaged.
- Page 20 INSTALLATION HOT WATER DELIVERY This water heater can deliver water at temperatures which can cause scalding. It is necessary and we recommend that a temperature limiting device be fitted between a Rheemglas or Optima water heater and the hot water outlets in any ablution area such as a bathroom or ensuite, to reduce the risk of scalding.
- Page 21 A RheemPlus water heater cannot be installed as part of a circulated hot water flow and return system in a building. If a Rheem water heater is to be installed as part of a circulated hot water flow and return system, a storage water heater able to provide a hot water outlet temperature of at least 60°C must be used.
- Page 22 INSTALLATION Circulated Hot Water Flow and Return Continuous Electric Water Heater Off-Peak or Time Controlled Electricity Supply A single or twin element electric water heater connected to an Off-Peak LEGEND electricity supply should not be installed as part of a circulated hot water flow and return system in a building.
- Page 23 INSTALLATION REDUCING HEAT LOSSES The cold water line to and the hot water line from the water heater must be insulated in accordance with the requirements of AS/NZS 3500.4. The insulation must be weatherproof and UV resistant if exposed. ANODE The vitreous enamel lined cylinder of the water heater is only covered by warranty when the total dissolved solids (TDS) content in the water is less than 2500 mg/L and when the correct colour coded anode is installed.
- Page 24 INSTALLATION PUSH THROUGH (FREE OUTLET) INSTALLATION It can be advantageous to plumb the water heater as a Push Through water heater in some cases. These installations can supply a single point only and normally use a 25 litre or 50 litre electric water heater.
