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. 
 
It is necessary to remove the pipe cover from underneath the gas booster, by undoing the retaining 
screws, in order to test the gas pressure at the inlet of the gas booster. Refit the pipe cover at the 
completion of the installation. 
 

BURNER GAS PRESSURE 
It is necessary to check the burner gas pressure at both the minimum and maximum operational 
settings. It is necessary to have the electrical supply to the water heater switched on, the hot water 
must be flowing and the burners on to check and if necessary adjust the operational gas pressures. 
 

 Warning: The removal of the front cover will expose 240 volt wiring. Take care not to touch wiring 

terminals. 

•  Ensure the burners are not operating. Close any hot taps and turn off the gas supply at the gas 

isolation valve. 

•  Remove the screws holding the front panel to the jacket. 

•  Gently disengage the front panel and pull forward to remove from the water heater. 

•  Locate the burner pressure test point on the main burner manifold and connect a manometer. 

•  Turn on the gas supply at the gas isolation valve.
