INSTALLATION 

 

THIS WATER HEATER IS FOR OUTDOOR INSTALLATION ONLY. 
THIS WATER HEATER IS NOT SUITABLE FOR POOL HEATING. 
Check the water heater is suitable for the gas type available 
(refer to the rating label on the water heater). 

 

INSTALLATION STANDARDS 

The water heater must be installed: 

 

by a qualified person, and 

 

in accordance with the installation instructions, and 

 

in compliance with Standards AS/NZS 3500.4, AS 5601 or AS/NZS 5601.1, 
as  applicable  under  local  regulations,  and  all  local  codes  and  regulatory 
authority requirements. 

In New Zealand, the installation must also conform to the New Zealand Building 
Code. 
 
All  packaging  materials  must  be  removed  from  the  water  heater  prior  to  its 
installation. This includes the removal of the cardboard base of the carton from 
the underside of the water heater. 
 

WATER HEATER APPLICATION 

This  water  heater  is  designed  for  use  in  a  single  family  domestic  dwelling  for 
the  purpose  of  heating  potable  water.  Its  use  in  an  application  other  than  this 
may shorten its life. 
 
If  this  water  heater  is  to  be  used  where  an  uninterrupted  hot  water  supply  is 
necessary  for  the  application  or  business,  then  there  should  be  back-up 
redundancy  within  the  hot  water  system  design.  This  should  ensure  the 
continuity of hot water supply in the event that this water heater was to become 
inoperable  for  any  reason.  We  recommend  you  provide  advice  to  the  system 
owner  about  their  needs  and  building  back-up  redundancy  into  the  hot  water 
supply system. 
 

Note:

  AS 3498  requires  that  a  water  heater  provides  the  means  to  inhibit  the 

growth  of  Legionella  bacteria  in  potable  water.  This  water  heater  can  satisfy 
this AS 3498 requirement provided it is operating and the thermostat setting is 
60°C or higher, including when it is used as an in-series booster water heater 
for a solar water heater.
