6.1.1 Plumbing Kits and installation Rinnai supplies specific Plumbing Kits with each boiler type, which must be fitted directly underneath the boiler on the supply and return pipe. Find in chapter 5.3 the dimensions. Use of the Rinnai boiler without the plumbing kit will void the warranty. i NOTICE i NOTICE i NOTICE To protect the entire heating system we recommend installing a dirt particle trap in the return circuit.
- Boiler system flushing (Not Boiler heat exchanger) When replacing an existing boiler the heating system should be flushed with the old boiler in place before the new boiler is added to the system. If the old boiler has already been removed a bypass must be piped in when the new boiler is installed in order to facilitate the flushing of the system. The boiler must be valved off from the system, while the system is flushed.
13. If the installation is a zone system be sure to purge out each zone individually 14. Close the auto feed on the system (F1) 15. Close the return side purge station (BD2) and disconnect the hose (H3). 16. Open the main valve on the system return (V3) 17. Close the bypass valve below the plumbing kit (V4). 18. Open shutoff valves on both the supply and return connections on the plumbing kit (V1 and V2). 19. Clean out the dirt trap 20. Test the pH of the water that will be used for filling the system 21.
If the installation resistance is over the stated value; the pump will rotate at maximum capacity and the load will be adjusted until an acceptable temperature difference between supply and return water has been obtained. If, after this, the temperature difference is still not acceptable then the boiler will switch off and wait until an acceptable temperature has arisen. If an unacceptable temperature is detected, the control will repeatedly try to achieve water flow over the boiler.
6.1.2 Side mounting kit for the Low Loss header A side mounting kit for the low loss header is available as an accessory. This kit relocates the low loss header from directly below the boiler to the left side of the boiler only. The kit includes all the parts required to relocate the low loss header including all mounting brackets and material. This kit provides an alternative to for installations with height limitations and allows for an alternative piping installation.
6.2 Expansion tank An expansion tank must be part of the central heating system. The expansion tank must be appropriate to the water content of the installation. The pre-charge pressure depends on the installation height above the mounted expansion tank. The expansion tank is NOT a part of the delivery and should be sourced locally. Please refer to the expansion tank manufacturer for further information. The Combi boiler Q175C is equipped with an expansion tank connection.
6.4 Gas connection ! DANGER Only work on gas lines if you are licensed for such work.
