Worcester Wave – smart control for heating and hot water The Wave is the first of a new generation of Worcester controls. The Wave is a smart, internet-connected programmable control for central heating and hot water which can be operated using a smart device. The Wave’s innovative programming enables it to have an ‘intelligent conversation’ with the boiler and take advantage of advanced control features such as weather and load compensation.
Quick to install The Wave is quick and easy to install: • Only requires a 2-core wire connection between the control and the boiler. EMS 2 Wire • All other connections are via the Wi-Fi network. • The Wave does not need an external wired sensor Greenstar boiler Wave unlike standard weather compensation controls. • The Wave uses online data which significantly reduces installation time and cost to the end user.
Site preparations and guidance All combi boilers require less installation time than a Installation and service clearances conventional boiler, for these reasons: The minimum clearances shown below should be allowed • • Highly versatile multi-directional fluing system • Combined ignition and control board means for installation and servicing. Compartment ventilation Zero pressure governor gas valve with fully modulating fan would only be required at these clearances.
Airing cupboard clearances – minimum clearances Boiler location The appliance may be installed in any room, although particular attention is drawn to the requirements of the 800mm 625mm IEE regulations applicable, and in Scotland the electrical provisions with respect to installation in a room containing a bath or shower. 100mm 1.

Important: bathroom locations and clearances Site preparation/portability • The boiler must not be installed in Zone 1 • Any switch or appliance control using mains electricity Greenstar Highflow CDi appliances are supplied with a floor mounted pre-plumbing jig. The jig enables all gas and must not be within reach of a person using the bath water services to be pre-plumbed and tested prior to fitting or shower the boiler.
Installation requirements Installation of Greenstar Highflow CDi combi boilers must System filling and make-up be in accordance with the relevant requirements of the To comply with the Water Authority requirements, the Gas Safety (Installation Use) Regulations at the time of system should be filled via a temporary hose connection installation, current IEE Wiring Regulations, local Building to the mains cold water supply, with a double check valve Regulations, Building Standards (Scotland) regulation
Natural gas supply Liquid Petroleum Gas (LPG) supply Appliances, when on a full output demand, will require The appliances, when on a hot water or full output demand, up to 3.1m3/hr of gas for the 440CDi and 4.4m3/hr of gas will require up to 2.3kg/hr of gas for the 440CDi and for the 550CDi. The gas meter and supply pipes must be 3.2kg/hr of gas for the 550CDi.
Cold water connection Showers Wherever possible the cold supply to the appliance should When a loose head shower with a flexible hose is used be the first connection off the mains supply, in order to over a bath or shower tray, the hose must be fixed so that minimise hot water flow reduction when cold water services the head cannot fall closer than 25mm (1in) above the top are operated.
The Worcester Greenstar System Filter Modern condensing boilers are precision-engineered and designed to run with a clean water heating system. Over time, dirty system water will damage a boiler and its components, causing failures and shortening the life of the overall system. Damaged boiler and system components • Blockages in primary heat exchanger • Increased wear on pumps • Blocked valves.
Features Benefits Safeguards the boiler against damage and Highly effective filter protects the efficiency of the system.
Condensate pipework All condensing boilers generate condensate discharge The condensate connection on Worcester appliances is in which needs to be piped away from the appliance using a 22mm polypropylene. The pipe should be extended and run plastic pipe. away from the appliance with a constant fall of 3º or at least 50mm in every metre away from the boiler. The amount of condensate generated depends on the efficiency and operating status of the appliance.
