DESIGN, INSTALLATION AND SERVICE INSTRUCTIONS

_____________________________________________________________________________________

GENERAL

This high efficiency wall mounted condensing boiler is designed to

provide central heating from a fully pumped open vented or sealed

water system when coupled to a thermal store or an indirect cylinder.

The central heating water temperature can be adjusted by the installer

to suit special applications.

Once the controls are set, the boiler operates automatically and the

boiler controller automatically activates the frost protection program to

prevent the boiler from freezing.

This boiler is for use with Natural Gas (G20) only at 20mbar inlet

pressure and is for use in GB &IE only.

Appliance category: I

These instructions cover the following boiler models and only apply to

the appliances sold and installed in Great Britain (GB) and Ireland (IE).

Page 3: Important Information
These boilers have been tested and certified for safety and performance. It is important that no alteration is made to the boiler unless it is approved in writing by Gledhill Ltd. The boiler meets the requirements of Statutory Instrument No 3083 i.e. ‘The Boiler (Efficiency) Regulations’...
Page 4 (e) Bench Mark Log Book As part of the industry wide ‘Benchmark’ initiative all Gledhill appliances now include a Benchmark Installation, Commissioning and Service Record Logbook. Please read this carefully and complete all sections relevant to this appliance.
Page 5 If you have a sealed heating system, contact your installation/service company as draining, refilling and pressurising MUST be carried out by a competent person. (e) As a safety feature, the boiler will stop working if the condensate drain becomes blocked. During freezing conditions this may be due to the forming of ice in the condensate drain external to the house.
Page 6 Free of charge replacement for any faulty components are available from Gledhill Ltd during the in-warranty period (normally 12 months). After this the spares can be obtained direct from Gledhill Ltd using the ‘Speed Spares’ service. Help and advice is also available from our Technical Help Line on 01253 474401.
Page 7: Operating The Boiler
2. OPERATING THE BOILER 2.1. HEATING SYSTEM AND BOILER (a) Sealed Systems A sealed heating system must be filled and pressurised by a competent person. Only light the boiler when you are sure that the system and the boiler have been filled and pressurised. The pressure should read at least 0.5bar, anything less than this figure could indicate a leak and you MUST contact your installation / servicing company.

(b) This boiler is for use on G20 natural gas only. The boiler is certified to the current issue of EN483 for performance and safety. It is important that no alteration is made to the boiler, without written permission of Gledhill Ltd. Where no British Standards exist, materials and equipment should be fit for their purpose and of suitable quality and workmanship.
Page 10 The main dimensions and the clearances required for the boilers are shown in diagram 3.1 for models GB30, GB25 and GB20 and diagram 3.2 for models GB15 and GB10. The technical data of the boilers is shown in tables 3.1 and 3.2. The boiler data badge is positioned on the inner door.

Page 12 3.5. CENTRAL HEATING AND WATER SYSTEM The Gledhill boiler is suitable for use with both vented and unvented traditional heating systems and also for use with the thermal storage systems e.g. Gledhill BoilerMate and Gledhill SysteMate. Plastic Pipes When plastic pipe is to be used for the heating system, this must be suitable for the maximum pressures and temperatures for the intended application.

Page 14 3.5.3. Gledhill BoilerMate Heating System The Gledhill Boiler is also suitable for use with a Gledhill BoilerMate; an integrated open vented heating system and mains pressure hot water appliance. This appliance is supplied with factory fitted and wired system controls and equipment e.g. pumps, valves etc. The BoilerMate uses a directly heated open vented primary store and is suitable for only vented heating systems as shown schematically in diagram 3.7.
Page 15 F & E cistern should be at least 450mm above the highest point on the system including the radiators 3.5.4. Gledhill SysteMate Heating System The Gledhill Boiler is also suitable for Mains Mains use with a Gledhill SysteMate; an...

Page 17 3.10. BOILER LOCATION AND VENTILATION 3.10.1. Boiler Location The boiler may be installed in any room although particular attention is drawn to the requirements of the current issue of BS7671 with respect to the installation of a boiler in a room containing a bath or a shower. Any electrical switch or boiler control using mains electricity supply should be so sited that a person using the bath or a shower cannot touch it.
Page 18 3.11.3. Flue Options The concentric flue systems and kits available for this boiler are listed below in table 3.4. Additional accessories and flue systems are also available for this boiler. See ‘Gledhill Boiler Flue Options Guide’ for configurations that are available.
Page 19 If a terminal guard is required, it must be positioned to provide minimum of 50mm clearance from any part of the terminal and be central over the terminal. A terminal guard for this boiler is shown in the Gledhill Boiler Flue Options Guide and is available from Gledhill Ltd quoting part number GF199.
Page 20 3.13. CONDENSATE DRAIN A plastic drainpipe must be fitted to the boiler to allow discharge of condensate to the suitable drain. A copper pipe is NOT suitable. Condensate should, if possible, be discharged into the internal household drainage system. If this is not practical, discharge can be made externally into the household drainage system or a purpose designed soak away.
