Operating with a Hot-Water Cylinder Redring strongly recommend that a direct electric, unvented cylinder be used for the production and storage of the hot water as this will be cheaper than an indirect cylinder; will require less plumbing (piping and valves) and is...
Service Valves When using the boiler for unvented hot water and heating, the two-port motorised valve should be inserted in the flow from the boiler. A Differential Pressure valve should then be connected between the flow and return at a point between the boiler and the two-port motorised valve.
Option # 2 - Operating with a Cylinder Thermostat & Room Thermostat (Circuit diagram 2.7.2 - page 19) Move the two brown wires from terminals # 1 & # 2 to terminals # 5 & # 6 respectively (1 to 5 and 2 to 6) The no-volt, normally open contacts of the room thermostat should be connected to terminals # 1 &...

Redring Xpelair Group fully supports this professional approach and recommends that the system is cleaned with an effective chemical cleanser and then protected long-term with a suitable inhibitor. Such products are available...
2.1 - Introduction The Redring Powerstream Ascari boiler is an all electric, domestic central heating boiler suitable for use on a 230v, 52A, 50 Hz supply. The unit is easy to install and requires no flue making it ideal for apartments or properties in conservation areas.
Should any water/steam be seen to be venting from this outlet, the boiler electricity supply should be switched off immediately and the Redring Xpelair Group Customer Service Centre contacted. •...
• Whilst the boiler and heating system may be filled from the cold mains water supply, the boiler must be isolated from this supply by a suitable break in the supply pipe during normal operation. • This boiler is not fitted with a filling loop. Any loop being fitted must comply with the Water Supply (Water Fittings) regulations in force at the time of installation.
2.4 - Preparation 2.4.1 - Opening the case The boiler is opened by unscrewing the bottom two bolts a couple of turns (they do not need to be completely removed). The front cover is then pulled away from the bottom and lifted off the two pins at the top of the casing. 2.4.2 - Location...

• Install the heating system to bring the flow and returns to the intended boiler location. • The system must be flushed prior to finally connecting the boiler, in order to remove any debris from the pipework. Do not use the fitted pressure relief valve to flush the system as particles may get trapped in the valve and cause incorrect operation.
2.6 - Electrical Electrical connections may become loosened during transportation. To avoid any risk, carefully check all electrical terminals for security and tightness.

Wiring external to the appliance must be in accordance with the current I.E.E Wiring Regulations (BS 7671) for electrical installations plus any local regulations which may apply. This appliance must be earthed The terminal blocks are fitted with cage-clamp electrical connectors. These are operated using a 2.5mm x 0.4mm blade screwdriver for the accessory terminals and a 3.5 x 0.5mm blade screwdriver for power terminals.
2.6.1 - Selecting Thermal Cut-Out The thermal cut-outs are situated at the top of the boiler and may be selected during the installation by re-routing the electrical connections. The boiler is factory set with the 100°C cut-out selected for use with a radiator heating system.
2.6.3 - Control Accessories Wiring 2.6.3.1 - Operating from a switched live RELAY • Terminals # 1 & # 2 are wires from terminals # 11 & # 14 of relay in electrical box • CC = 3 speed pump •...
2.9 - Commissioning & Testing • Check that the pressure of the expansion vessel is at its factory setting of 1bar (0.1 MPa) • The heating system should be filled using the approved installed filling loop. Ensure all radiator valves are open.
2.10.1- Boiler Configuration Parameter Listing (read in conjunction with Section 2.10.2) With this mode selected, the Domestic Hot Water temp will increase to 65°C. A thermostatic mixer valve should be fitted to avoid scalding.
2.10.2 - Boiler Configuration - continued Parameter Selects the maximum temperature of the water circulating in the heating circuit. Selects the minimum temperature of the water circulating in the heating circuit. Select ‘01’ if operating from a switched live or if a room thermostat is installed and connected Do not select ‘02’.
Pressing the key a second time displays in front of °C with the boilers temperature setting displayed beneath (See Section 2.13 to adjust this setting) The following additional displays are available dependant on parameter settings. Value Display Description Availability Note Beneath In °C.
Shortly after Installation - turn ‘OFF’ electrical supply to the boiler and re-check the tightness of all electrical connections of the power supply and the elements Monthly - check the pressure in the heating circuit (minimum 1 bar when cold) Annually - Redring Xpelair Group recommend that the boiler be checked by a qualified Technician.
2.19 - Overheating & Replacement of Heating Elements Under-floor Heating • In the case of overheating, the 60°C thermal cut-out will cut power to the heating elements Radiators • The 100°C thermal cut-out will also cut power to the heating elements After solving the cause of any overheat issue, reset the thermal cut-out by pressing the red button in the centre of the sensor’s head.
). it indicates that the system pressure has fallen below the minimum operating pressure. • Check to see if water has discharged from the pressure relief valve - if so, call the Redring Xpelair Group Customer Service Department • Check for leaks from the system Once the fault has been cleared, the boiler will turn ‘ON’...
