Page 3: Introduction
The PremierPlus SystemFit primary circuit can be connected to a variety of gas or oil fired boiler types, either open vented or sealed system. It is not recommended for use with “system” boilers as these already incorporate their own circulating pump and controls.

If you choose to install the PremierPlus SystemFit in the highest point in the property (e.g. loft space), it is advisable to install an additional automatic air vent (AAV) (not supplied - available as spare, part number 95 605 050) above the pump to enable air to be removed from the system.
Page 5 NOTE: Accessories, plumbing fittings and pipework should have a rated operating pressure of at least 6 bar. Outlets situated higher than the PremierPlus SystemFit unit will give outlet pressures lower than that at the heater, a 10m height difference will result in a 1 bar pressure reduction at the outlet fitting.

More flow noise may be experienced from small bore pipes due to the increased water velocity through them. A stopcock or servicing valve should be incorporated into the cold water supply to enable the PremierPlus SystemFit and its associated controls to be isolated and serviced.
Page 11 HOT WATER OUTLET Ideally the pipework from the PremierPlus SystemFit to the outlet fittings should be in 22mm pipe with short runs of 15mm pipe to showers and basin taps. Small bore pipe can also be used to suit some taps, but runs should be of minimum length.

Page 13: Installation - Discharge
INSTALLATION - DISCHARGE It is a requirement of Building Regulation G3 that any discharge from an unvented system is conveyed to where it is visible, but will not cause danger to persons in or about the building. The tundish and discharge pipes should be fitted in accordance with the requirements and guidance notes of Building Regulation G3.
Page 14 Under no circumstances should the factory fitted temperature/pressure relief valve be removed other than by a competent person. To do so will invalidate any guarantee or claim. • The cold water combination valve assembly must be fitted on the PremierPlus SystemFit water supply to the PremierPlus SystemFit cylinder. • No control or safety valves should be tampered with or used for any other purpose.

HEATING SYSTEM CONTROLS The controls provided with the PremierPlus SystemFit will ensure the safe operation of the unit within a central heating system. Connection to the various system components is made via the wiring centre fitted to the front of the PremierPlus SystemFit, refer to figure 8, page 17 and the terminal identification labels within the wiring centre to aid in connecting the various external system components such as the mains supply, programmer and boiler.

The pump should run and the boiler fire (a flame symbol appears in the controller display). The primary flow to the PremierPlus SystemFit and the radiator circuit should become hot, if it does not check for a wiring or piping error.
Page 19: Maintenance
NOTE: it may be necessary to cool the PremierPlus SystemFit down to allow the indirect thermostat to call for heat, it may also be necessary to increase the required room temperature setting if the room temperature has already reached that programmed. The pump should run and the boiler fire (both a tap symbol and a flame symbol should appear in the controller display).

DOWN THE BOILER. DO NOT TURN OFF ANY WATER SUPPLY. CONTACT A COMPETENT INSTALLER FOR UNVENTED WATER HEATERS TO CHECK THE SYSTEM. DO NOT TAMPER WITH ANY OF THE SAFETY VALVES FITTED TO THE PREMIERPLUS SYSTEMFIT. IF A FAULT IS SUSPECTED, CONTACT A COMPETENT INSTALLER.
Page 21 HEATING BY BOILER The PremierPlus SystemFit cylinder units are fitted with an indirect thermostat and thermal cut-out. These controls must be wired in series with the 2 port motorised zone valve supplied to interrupt the flow of primary water around the heat exchanger coil when the control temperature has been reached.
