COMMISSIONING
INITIAL CHECKS
1. Check that the power supply to the system is switched OFF.
2. Check that an adequate water supply is available to the hot water system.
Water supply pressure shall not exceed 800kPa.
3. OPEN cold water inlet valve, hot water outlet valve, (and hot water return valve with pump option only)
Check all individual water heater isolation valves are OPEN;
4. Check that the system is fully charged, all the air is bled from the system and no leaks are evident.
5. Check the pipe work for leaks
6. OPEN all individual water heater gas isolation valves and purge gas lines.
7. Check the gas pipe work for leaks
To complete the installation, it is necessary to check the gas supply pressure at the inlet to the water heater
(refer to
“Gas Inlet Pressure” on page 46 ), the minimum test point pressure and the maximum test point
pressure (refer to “Burner Gas Pressure” on page 48 ).
Warning: Upon completion of the installation and commissioning of the water heater, leave this guide
with a responsible officer. DO NOT leave this guide inside of the cover of the water heater, as it may interfere
with the safe operation of the water heater or ignite when the water heater is turned on.
GAS INLET PRESSURE
IMPORTANT - CHECK
the gas supply pressure at the inlet to the water heater with the water heater and all
other gas burning appliances in the premises operating (burners alight). The minimum gas supply pressure
is:
Natural Gas 1.13 kPa Propane 2.75 kPa
If this minimum cannot be achieved, it may indicate the meter or the gas line to the water heater is
undersized. It is important to ensure that an adequate gas supply pressure is available to the water heater
when other gas burning appliances, on the same gas supply, are operating.
