TEMPERATURE ADJUSTMENTS. (By licensed installers only)
The Rapid 26 can be incrementally preset to temperatures between 50ºC to 74ºC.
Note. To limit water to a maximum of 50ºC to bathrooms and en-suites; an approved
temperature limiting device is required to be fitted to comply with AS/NZS 3500.4.
Setting the unit to 50ºC does NOT negate the need to fit an approved temperature
limiting device.
NOTE: THE POWER MUST BE TURNED OFF PRIOR TO
CHANGING THIS SET OF SWITCHES.
Check gas supply pressure to heater and the burners.
To ensure that the heater will operate safely and achieve its rated
delivery check both the gas supply pressure and burner pressure.
Checking the gas supply inlet pressure:
1. Close the gas isolation valve at the inlet to the water heater.
2. Connect a manometer to the gas inlet test point on the gas
connection fitting under the water heater.
3. Open the gas isolation valve fully.
4. Open 2 hot taps fully and ensure all the heater’s burners are alight.
5. Turn on all other gas appliances in the premises at their maximum gas rate
6. The gas pressure reading on the manometer should be.
Natural Gas 1.13 – 3.5kPa. LPG 2.75 – 3.5kPa
6. If the manometer reading is lower than the specified range then either the gas pipe to
the water heater is undersized and needs to be increased or adjustment is required at
the gas supply regulator.
7. If the manometer reading is above the specified range then adjustment is required at
the gas supply regulator.
