The Electrastream is a 9 kW (30,000 btu) system suitable for flats, apartments, offices and other small dwellings.
Page 3 WARNINGS: DO NOT remove or adjust any component part of the unvented water heater: contact the INSTALLER. Plumbing must remain as supplied, do not add to or change any plumbing or connections. In the event of hot water/steam being emitted at the discharge pipe or tundish, switch the system off and contact installer –...

Page 6 The location and position of the water conditioner should be as per the manufacturer’s recommendations. Check water pressure & flow rates: Stuart Turner recommends 1.5 bar pressure at 20 litres/minute flow rate as the minimum requirements for satisfactory operation. The unit will still operate below this, but it may not be possible to run two or more outlets at the same time.

Page 9: Pipework Connections
3 PIPEWORK CONNECTIONS Hot/cold services: The cold water mains supply is connected to the combination valve via the lever isolating valve supplied, which limits incoming pressure to 3.5 bar and has an integral NRV. The hot water outlet pipework is connected to the outlet of the mixing valve via the lever isolating valve supplied.
Page 10 The discharge pipe (D1) from the vessel up to and including the tundish is supplied by Stuart Turner Ltd. Where otherwise the installation should include the discharge pipe(s) (D1) from the safety device(s). In either case the tundish should be vertical, located in...
Page 11 Where a single common discharge pipe serves more than one system, it should be at least one pipe size larger than the largest individual discharge pipe (D2) to be connected. The discharge pipe should not be connected to a soil discharge stack unless it can be demonstrated that the soil discharge stack is capable of safely withstanding temperatures of the water discharged, in which case it should: a) Contain a mechanical seal, not incorporating a water trap, which allows water into...

Page 13: Electrical Installation
4 ELECTRICAL INSTALLATION Regulations: The electrical installation must be carried out in accordance with the current national electrical regulations and installed by a qualified person. 4.2 Before starting work on the electrical supply ensure power supply is isolated. 4.3 DO NOT allow the supply cord to contact hot surfaces 4.4 DO NOT switch the power on until the unit has been filled with water and has been earthed.
Page 14 4.10 Wiring of the unit: The Electrastream Unit is supplied wired, therefore only a mains cable (not supplied) is required to be installed through the cable gland located at the top of the RCD box. This 3 core cable suitably sized is connected into the live, neutral and earth of the RCD.

Page 16: Commissioning
5 COMMISSIONING IMPORTANT it is the responsibility of the installer to ensure that the Electrastream System is properly commissioned. Should the commissioning not be carried out, then the manufacturers guarantee and any extended warranty, will become null and void. Wet System 5.2 System flushing: The pipework system should be flushed out prior to the Electrastream being connected to ensure any contaminants/chemical residues and foreign bodies are removed from elsewhere in the system.
Page 17 f) Test the operation of the Temperature & Pressure relief valve by turning the manual test cap and ensure the water flows freely and safely to waste. g) Test the operation of the combination valve PRV by turning the manual test cap and ensure the water flows freely and safely to waste.

Page 20 6 GENERAL OPERATION 6.11 Heating motorised valve: When the room thermostat is calling for heat and the Electrastream control unit is set for heat ON, the heating motorised valve will open allowing water to the radiators. Display icon ‘Valve V’ indicates valve is open 6.12 Pump: The heating circulating pump is controlled by Electrastream Control Unit in response to the room thermostat.
Page 21 6.17 Temperature & pressure relief discharge: Note: The Tundish or discharge pipe should remain visible, do not box in or cover up. The Electrastream hot water cylinder has a Temperature/ Pressure relief valve (TPRV); in the event of the pressure within the cylinder becoming too high, the TPR valve will vent. The heating system has its own Pressure relief valve (PRV) and in the event of the pressure within the heating system becoming too high, the PRV will vent.
Page 22 6.21 Setting heat and hot water requirements: Figure below shows a 24 hour clock with typical use of the Electrastream during ‘Off- Peak’ economy 10 settings. Note:- Self Test – After 3am each day the unit carries out a self test period for approx. 30 minutes.
