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 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 with NZS 5261, as applicable under local regulations, and 

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 pallet from the underside of the water heater. 
 

WATER HEATER APPLICATION 

This water heater is designed for the purpose of heating for potable water or hydronic heating applications. 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 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  backup  redundancy  into  the  hot  water  supply 
system. 
 

Check the water heater is suitable for the gas type available. The gas type is marked on the side panel near 
the gas connection entry and shown on the rating label. 

All  packaging  must  be  removed  from  the  water  heater  prior  to  its  installation.  The  installation  kit  (including  the 
pressure relief valve) may be supplied inside the water heater casing. This kit must be removed before the water 
heater is operated. 

READ THESE INSTRUCTIONS IN FULL 

 

INSPECTION OF EQUIPMENT 

Check  the  water  heater  and  associated  equipment  for  any  damage.  DO  NOT  INSTALL  OR  OPERATE  ANY 
WATER  HEATER  THAT  HAS  BEEN  DAMAGED.  ANY  ADDITIONAL  DAMAGE  OR  FAULTS  CAUSED  BY 
UNAUTHORISED START UP MAY NOT BE COVERED BY WARRANTY. 

WATER HEATER LOCATION 

This water heater is supplied for outdoor installation only. For indoor installations the correct indoor conversion kit 
is required (refer to 

“Hood Conversion” on page 16). Whether located outdoor or indoor, the position of the water 

heater should be chosen with safety and service in mind. Make sure people (particularly children) will not touch the 
flue outlet. The flue terminal must be clear of obstructions and shrubbery. 

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 pressure relief valve lever is accessible and the entire front panel and burner 
assembly  can  be  removed  for  service.  Remember  you  may  have  to  remove  the  entire  water  heater  later  for 
servicing. 

You must be able to read the information on the rating label. 

The  water  heater  must  not  be  installed  in  an  area  with  a  corrosive  atmosphere  where  chemicals  are  stored  or 
where  aerosol  propellants  are  released.  Remember  the  air  may  be  safe  to  breathe,  but  when  it  goes  through  a 
flame, chemical changes take place which may attack the water heater. 

The water heater must be mounted on a level fire proof base such as a concrete slab, concrete plinth, steel plate 
etc. Water heaters must NOT be installed on carpeting. 

The front of the water heater must not be obstructed by any gas or water piping, electrical conduits, etc.
