INSTALLATION 

 

THIS WATER HEATER IS NOT SUITABLE FOR POOL HEATING 

 

INSTALLATION STANDARDS 

The water heater must be installed: 

 

by a qualified person, and 

 

in accordance with the installation instructions, and 

 

to conform to Clauses G12 and H1 of the New Zealand Building Code, and 

 

in  compliance  with  Standards  AS/NZS 3500.4  and  AS/NZS 3000,  and  all 
local codes and regulatory authority requirements. 

 

 Warning: 

– This water heater may deliver water at high temperature. Refer 

to  the  New  Zealand  Building  Code,  local  requirements  and  these  installation 
instructions  to  determine  if  additional  delivery  temperature  control  is  required. 
Refer to 

“Hot Water Delivery”

 on page 26. 

 
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. 
 

WATER HEATER LOCATION 

The  water  heater  is  suitable  for  either  indoor  or  outdoor  installation.  Whether 
located outdoor or indoor, the water heater should be installed close to the most 
frequently used outlet and its position chosen with safety and service in mind. 
 
Clearance must be allowed for servicing of the water heater. The water heater 
must be accessible without the use of a ladder or scaffold. 
 
Make sure the temperature pressure relief valve lever is accessible and the front 
cover, thermostat and heating unit can be removed for service.
