Sapphire Operation & Installation Manual
HEATER ENGINE - GENERAL INSTALLATION
GAS SUPPLY
Installation of consumer piping
The gas supply (consumer piping), termination is inside the heater and enters through the rear of the appliance.
Refer to the dimensional drawings on page 24 for appliance gas inlet location and other relevant dimensions.
Gas pipe sizing must consider the gas input to this appliance as well as all other gas appliances
in the premises. The gas meter and regulator must be specified for the total gas rate.
A suitable sizing chart such as the one in AS 5601 should be used.
Confirm correct gas type (see labels located on top or rear panels). Refer to local gas authority for
confirmation of gas type if you are in doubt.
Mark off the location for the vertical centre line
of the heater enclosure (inbuilt
installations) or heater (freestanding installations).
To the right of the vertical centre line
, mark off both the vertical
and
horizontal
location for the gas supply penetration (consumer piping). For
measurements refer to the Gas Supply Dimension Table below.
Inbuilt Models:
The length of the gas supply (consumer piping) termination
is measured from the front of the enclosure.
Freestanding Models:
The length of the gas supply (consumer piping)
termination
is measured from the back of the heater plus 95mm.
For freestanding models the minimum clearance of 75mm from
the wall must be observed.
At the minimum clearance the total length of the consumer pipe is
170mm (75mm + 95mm)

Once the consumer piping has been terminated to the above requirements the
supplied flexible gas connection
may then be fitted.
Purging Gas Supply
Foreign materials and debris such as swarf, filings, etc.
MUST BE
purged/
removed from the gas supply, failure to do so may cause damage to the gas
control valve causing it to malfunction.
Leak Testing The Connection
With the supplied plug
inserted into the end of the flexible gas connection leak
test all joints.
Use a soapy solution to test all gas connections. If a leak is present bubbles will form at the leak
point. When finished remove any residue with a rag. Prevent any soapy solution from coming in
contact with electrical components.
