7. Check the hot water delivery temperature by placing a suitable thermometer at the hot water
outlet closest to the gas booster. This is usually the hot water outlet in the kitchen. The delivery
temperature should be greater than 55°C (this temperature allows for heat losses in pipe work).
If the delivery temperature at the hot water outlet is lower than 55°C, check the delivery
temperature at the outlet of the gas booster. It should be within 2°C of the set point, usually
60°C. If not, refer to the section
'Hot Water Delivery temperature' refer to page 34.
8. Close the cold water inlet ('trio') valve on the storage cylinder inlet and inspect and clean the
strainer. Repeat for the strainer connected at the inlet of the gas booster. This procedure may
need to be repeated to ensure the strainers remains clear, especially on new installations.
9. Confirm the hot water delivery temperature from the gas booster. This is done by checking the
hot water delivery temperature at an untempered outlet close to the water heater. This is
usually the hot water outlet in the kitchen.The untempered hot water delivery should be
between 55°C & 60°C.
Temperature Limiting Devices
1. Commission any temperature limiting devices in accordance with the instructions supplied by
the manufacturer.
2. Confirm the hot water delivery temperature at a tempered water outlet. Tempered water outlets
should be those supplying areas primarily used for the purposes of personal hygiene such as
bathrooms. The hot water delivery temperature should not exceed 50°C or 45°C as detailed in
the section
'Hot Water Delivery temperature' refer to page 34.
SOLAR HEATING
1. Remove any cardboard or tarp covers that may have been placed over the solar collectors to
prevent them from heating water during installation and commissioning.
2. Activate electrical power to the Rinnai gas booster. Solar heating of the water in the cylinder will
now commence when sufficient solar radiation is available.
FINISHING THE INSTALLATION
• After testing is completed explain to the householder the functions and operation of solar water
heater components. Also explain to the householder the importance of carrying out
Maintenance as per separate ‘Warranty Terms and Conditions’ document.
• Leave this Manual with the householder.
• Remind the householder to complete the 'Warranty Certificate' provided in the separate
‘Warranty Terms and Conditions’ document.
DRAINING INSTRUCTIONS
1. The power supply to the gas booster must be switched off.
2. Close the cold water mains supply stop cock.
3. Open a hot tap to relieve pressure.
4. Disconnect the cold water connection to the Thermo-arrest (T/A) valve.
5. Remove the brass plug on the bottom right hand side of the collector bank.
6. Disconnect the ‘water inlet’ and ‘water outlet’ connections at the gas booster.
7. The system will now drain all water.
