TANK WATER SUPPLY 
If the water heater is supplied with water from a tank supply, then the bottom of 
the supply tank must be at least 1 m above the highest hot water outlet. Take 
care to avoid air locks. The cold water line to the water heater should be 
adequately sized and fitted with a full flow gate valve or ball valve. 
 
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 hot water outlets in any 
ablution and public areas such as a bathroom, ensuite or public amenities, to 
reduce the risk of scalding. The installing plumber may have a legal obligation 
to ensure the installation of this water heater meets the delivery water 
temperature requirements of AS/NZS 
3500.4 so that scalding water 
temperatures are not delivered to a bathroom, ensuite or other ablution or 
public area. 
 
Where a temperature limiting device is installed adjacent to the water heater, 
the cold water line to the temperature limiting device can be branched off the 
cold water line either before or after the isolation valve, pressure limiting valve 
and non return valve to the water heater. If an expansion control valve is 
required, it must always be installed after the non return valve and be the last 
valve prior to the water heater. 
 
If a pressure limiting valve is installed on the cold water line to the water heater 
and the cold water line to a temperature limiting device branches off before this 
valve or from another cold water line in the premises, then a pressure limiting 
valve may be required prior to the temperature limiting device.
