Detail of system treatment should be added for future reference. 6. For information or advice regarding any of the above contact Baxi Customer Support 0344 871 1525. 5.2.7 Expansion Vessel (CH only) 1. The appliance expansion vessel is pre-charged to 1.0 bar.
Before Installation 5.2.8 Safety Pressure Relief Valve See B.S. 6798 for full details. 1. The pressure relief valve (Fig. 5) is set at 3 bar, therefore all pipework, fittings, etc. should be suitable for pressures in excess of 3 bar and temperature in excess of 100°C. 2.
Before Installation Choice of the Location 5.3.1 Location of the Appliance 1. The boiler may be fitted to any suitable wall with the flue passing through an outside wall or roof and discharging to atmosphere in a position permitting satisfactory removal of combustion products and providing an adequate air supply.
Before Installation 5.3.5 Condensate Drain Examples are shown of the following methods of termination:- i) to an internal soil & vent pipe FAILURE TO INSTALL THE CONDENSATE ii) via an internal discharge branch (e.g. sink waste) DISCHARGE PIPEWORK CORRECTLY WILL AFFECT downstream of the trap THE RELIABLE OPERATION OF THE BOILER.

Before Installation 9. If the boiler is fitted in an unheated location the entire condensate discharge pipe should be treated as an external run iii) Termination to a drain Boiler and sized and insulated accordingly. or gully 10. In all cases discharge pipe must be installed to aid disposal of the condensate.
Before Installation 5.3.6 Clearances 1. A flat vertical area is required for the installation of the boiler. 2. These dimensions include the necessary clearances around the boiler for case removal, spanner access and air movement. Additional clearances may be required for the passage of pipes around local obstructions such as joists running parallel to the front face of the boiler.
Before Installation 5.3.7 Flue/Chimney Location 1. The following guidelines indicate the general requirements for siting balanced flue terminals. For GB recommendations are given in BS 5440 Pt 1. For IE recommendations are given in the current edition of I.S. 813 “Domestic Gas Installations”. Due to the nature of the boiler a plume of water vapour will be discharged from the flue.
Page 33
Before Installation Under car ports we recommend the use of the plume displacement kit. The terminal position must ensure the safe and nuisance - free dispersal of combustion products. 2. If the terminal discharges onto a pathway or passageway, check that combustion products will not cause a nuisance and that the terminal will not obstruct the passageway.
Before Installation 5.3.8 Horizontal Flue/Chimney Systems 1. The standard telescopic flue is suitable only for horizontal termination applications. (ii) 2. All fittings should be fully engaged.
