 Kelvinator Gas Continuous Flow hot water system

The water heater requires careful and correct installation 
to ensure safe and efficient operation. This manual must be 
followed exactly. Read the 

SAFETY GUIDELINES

 and the 

IMPORTANT

 sections at the beginning of this manual. 

Confirm the water heater suitability 

Check the gas type label and the rating plate for the correct 
gas type, gas pressure, water pressure and electrical rating 
for your application. Do not install this water heater if these 
requirements can’t be met. 
If this water heater is to be installed in a recess box, please 
refer to the installation manual supplied with the recess box 
for specific instructions regarding this type of installation.

caution

•  The water heater must be installed outdoors only. Do not 

install the water heater indoors. 

•  This equipment is not suitable for pool or spa heating. 
•  Water hardness may affect the water heater. It may be 

damaged. It is important that the water heater is installed 
in water conditions that are suitable for its efficient,  
long term use. 

•  This is a water heating apparatus only and the final fitness 

of water delivered is dependent upon the quality of water 
supplied to this system.  

•  The connection, attachment, integration or general 

association of other equipment or parts not specified by 
the water heater which either directly or indirectly affect 
the operation or performance of this equipment – could 
void the warranty. 

•  Before making connections to the water heater, remove 

any transit protection designed to prevent dirt and debris 
from entering the water heater.

•  The manifold pressure is preset at the factory. It is 

computer controlled and does not need adjustment. 

•  Occupants are to be advised of any inconveniences which 

could occur such as disconnection of services. 

•  Please follow the electrical earthing procedure outlined in 

AS3500.4 before cutting or uncoupling existing metallic 
pipework. 

•  To ensure the optimal performance of the water heater, it 

should be installed as close as practical to the most used 
hot water fixtures and have 20mm insulation covering the 
hot water piping. This will minimise heat loss, water usage 
and cost to the customer. Keep in mind though that a 
minimum distance of three metres is required between the 
outlet of the water heater and the first fixture (minimum 
one metre for 60°C and 70°C models).

•  The water heater requires a fireproof back plate if installed 

on timber wall. 

Selecting an installation location 

Carefully read this section before selecting the installation 
location and installing the water heater. The installer must 
follow these precautions exactly. 

caution

•  Although the water heater is designed to operate with 

minimal noise, it is recommended that you do not install 
the water heater adjacent to bedrooms or other areas 
designed to be quiet.

•  Locate your water heater close to a drain where leakage 

will not damage surrounding areas. As with any water 
heating appliance, the potential for leakage at some time 
during the life of the product does exist. 

•  The water heater shall be installed far away from any 

flammable or combustible materials including wood and 
cardboard. It must also have adequate ventilation to allow 
the proper combustion of the gas inside the heater to 
take place.

warning

•  Ensure every care is taken to warn occupants of the 

building and the public of any injury that may occur from 
falling tools, open trenches, water connections or any 
other general hazard. 

•  Make sure the water heater will have enough 

combustion air and proper ventilation. 

•  Keep the area around the water heater clean. Particles 

may clog the air vent, reduce fan function, or cause 
improper combustion. 

•  Locate the water heater to allow for easy access for 

service and maintenance. Install the water heater so that 
it can be connected or removed easily. 

•  Do not locate your water heater in a pit or any location 

where gas and water can accumulate. 

•  Check the proximity of gas and electrical lines so as not 

to create a hazard and avoid access problems for other 
services. 

•  It must be located in accordance with the requirements 

of AS5601 and have sufficient clearances from eaves, 
windows, vents etc. – see the diagram on p.9. 

•  Exemption from Prescribed Statutory Requirement: 

AS5601-2000 Clause 5.13.6.5, This relates to the physical 
separation distance specification where multiple 
appliances are employed. That equates to a minimum 
150mm horizontal flue separation distance allowing  
appliances to be placed side by side in the same  
vertical plane 

•  Most load bearing walls such as brick, brick/veneer, 

weatherboard and stud-frames are suitable locations. 

•  Securely fasten the water heater to the wall with a fixing 

solution suitable to the type of material the wall is made 
from. A minimum of two screws or bolts at the top and 
two screws or bolts at the bottom must be used.

Note: Refer to pages 6 & 7 for fixing positions.
