Boiler Termination to an internal soil and vent pipe Boiler External termination via internal discharge branch e.g. sink waste - downstream 50 mm per metre of pipe run 2,5° Minimum fall Sink 50 mm per metre of pipe run 2,5° Minimum fall Pipe must terminate above water level but below surrounding surface 450 mm min Boiler Termination to a drain or gully Pipe must terminate above water level but below surrounding surface Boiler Termination to a purpose made soakaway 500 mm min 50 mm per metre of pipe run 2,5° Minimum fall 50 mm per metre of pipe run 2,5° Minimum fall Holes in the soak-away must face away from the building FAILURE TO INSTALL THE CONDENSATE DISCHARGE PIPEWORK CORRECTLY WILL AFFECT THE RELIABLE OPERATION OF THE BOILER The condensate discharge pipe MUST NOT RISE at any point along its length. There MUST be a fall of AT LEAST 2.5° (50mm per metre) along the entire run. 1. The condensate outlet will accept 21.5 mm (3/4 in) plastic overflow pipe which should generally discharge internally into the house hold drainage system. If this is not possible, discharge into an outside drain is acceptable. 2. Ensure the discharge of condensate complies with any national or local regulations in force. BS 6798:2000 & Part H1 of the Building Regulations give further guidance. 3. The discharge pipe should be run in a proprietary drain pipe material e.g. PVC, PVC-U, ABS, PVC-C or PP. 4. Metal pipework is NOT suitable for use in condensate discharge systems. 5. The pipe should be a minimum of 21.5 mm diameter and must be supported using suitably spaced clips to prevent sagging. 6. It is advisable to keep the condensate pipe internal. 7. External runs greater than 3 metres or runs in cold areas should use 32 mm waste pipe. 8. If the boiler is fitted in an unheated location the entire condensate discharge pipe should be treated as an external run. 9. In all cases discharge pipe must be installed to aid disposal of the condensate. To reduce the risk of condensate being trapped, as few bends and fittings as possible should be used. 10. When discharging condensate into a soil stack or waste pipe the effects of existing plumbing must be considered. If soil pipes or waste pipes are subjected to internal pressure fluctuations when WC’s are flushed or sinks emptied then back-pressure may force water out of the boiler trap and cause appliance lockout. Examples are shown of the following methods of termination: i) to an internal soil & vent pipe ii) via an internal discharge branch (e.g. sink waste) iii) to a drain or gully iv) to a purpose made soakaway 24
4.4.5. Adjustable by-pass The boiler is equipped by an adjustable by-pass. By-pass operation can be inhibited. Pic. 15A shows an adjusting by-pass screw set for by-pass operation preclusion. Pic. 15B shows an adjusting by-pass screw set for by-pass operation. The boiler is supplied with by-pass set to closed by-pass. Closed By-pass Open By-pass pic.15 A pic.15 B 4.5. Flue options 4.5.1. Air intake / flue gas discharge system As far as flue gas discharge into the atmosphere and air intake / flue gas discharge systems are concerned, comply with laws enforced in the country of installation, which are considered as fully transcribed in this manual. In accordance with BS 5440 Part 1 and BS 5440 Part 2 the boiler is equipped with safety devices checking correct flue gas exhaustion. Should an air/flue gas system malfunction occur, the safety devices shut down the boiler and flashing red light 4. It is strictly forbidden to tamper with and/or prevent operation of such safety devices. Should the boiler repeatedly shut down, it is necessary to have air/flue gas system ducts inspected, as they might be obstructed or inadequate to flue gas discharge into the atmosphere. In air intake/flue gas discharge systems, specific, manufacturer approved, condensate acid-resistant systems for condensing boiler are to be used. Flue gas discharge pipes are to be installed tilted toward the boiler so that condensate runs in the direction of the combustion chamber, which is designed for condensate collection and drainage. Should the above procedure not be possible to be implemented, it is necessary to install, in condensate stagnation areas, devices designed for condensate collection and conveying to the condensate drain system. It is necessary to avoid formation of condensate stagnation areas in the flue gas discharge system, with the exception of the condensate drain siphon eventually connected to the discharge system itself. The manufacture shall not be held liable for damage resulting in incorrect installation, use, modification of the equipment or non-observance of instructions provided by the manufacturer or applicable installation standards involving the product. pic. 16 LEGENDA A Air intake - S Flue gas discharge - Condensate - Rain 25
