HOT WATER DELIVERY (WATER HEATING APPLICATIONS) 

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 the water heating system 
and  the  hot  water  outlets  in  any  ablution  and  public  areas  such  as  bathrooms,  ensuites  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 hot water storage tanks, 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 storage tanks. 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 heating system. 

If a pressure limiting valve is installed on the cold water line to the water heating system 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 of an equal pressure setting may be required prior to the temperature limiting device. 

REDUCING HEAT LOSSES (WATER HEATING APPLICATIONS) 

The  cold  water  line  to  and  the  hot  water  line  from  the  storage  cylinder  must  be  insulated  in  accordance  with  the 
requirements of AS/NZS 3500.4. The insulation must be weatherproof and UV resistant if exposed. 

Keep temperature settings down. Lower temperatures reduce heat losses and prolong storage cylinder life. Do not 
set  the  controlling  electronic  thermostat  above  70°C  unless  it  is  necessary.  A  time  clock  to  control  the  electrical 
supply can be used to switch off the water heater during hours or days when it is not in use. 

HOOD CONVERSION 

To convert a water heater from an outdoor configuration to an Indoor or High Wind Top configuration, proceed as 
follows: 

1.  Remove the flue terminal (outdoor hood) from the water heater leaving the jacket top in place. 

Place the stack adaptor over the flue collector and secure into place with self tapping screws. 

Fit the  draft diverter  over the spigot and sit squarely  on the stack adapter.  Secure in place  using self tapping 

screws. 

(Indoor  installations  only)  Install  and  connect  the  secondary  flue  to  the  draft  diverter  in  accordance  with  the 

requirements of AS 5601. 

NOTE

: For High Wind Top conversion follow steps 1  to 3  and assess whether tie downs for the High Wind Cowl 

are required.
