product Information on compact burners Digital combustion technology Weishaupt gas burners, WG1 to WG4 (12.5 55 kw)
Hot for quality Our motivation is technological progress, which has been driving us for more than 5 years to set new standards for the combustion industry. Weishaupt s own Research and Development Centre is constantly working on both new developments and the optimisation of exisitng products. It is our goal and our responsibility to go above and beyond current legislative requirements in developing combustion systems which produce fewer and fewer emissions, save more and more energy, and in so doing combine ecology and economy in a practical manner. Therefore, not only do we invest in research and technology but we also only ever work on the best materials with modern tools and we carry out meticulous quality control checks. It has been proven over a million times in the field that heating specialists and customers hold Weishaupt burners to be reliable, long lasting, environmentally friendly and technoloically advanced. A fact also documented by numerous design and innovation prizes. Over 6 burners are manufactured daily at our ultra-modern production facilities in Schwendi. Every single burner is subjected to a mechanical and electrical function test. The combination of technology with an effective quality control system safeguards Weishaupt s reknowned reputation for quality. A new burner is always an investment in the future. Cost needs to be well balanced against use, but the final deciding factors for long term sucess are quality, technology and safety. Deciding for Weishaupt burners is therefore a safe investment in the future. Ultra-modern research and production methods and rigourous quality control ensures the quality for which Weishaupt is reknowned 2
A hallmark of practical combustion technology Coded plugs for safe electrical connection All components are easily accessible Simple commissioning and diagnosis A safe investment in the future Reliable and economical: The miilionfold sucess of the Weishaupt compact burners is the result of orienting without compromise towards quality and the customer. The technology has been constantly developed and improved over decades. The latest production methods and stringent quality checks of all products ensure Weishaupt s reputation for quality. You are making a safe investment in the future. Large capacity range The large capacity range of 12.5 to 55 kw makes the burners suitable for the widest range of heat exchangers. Electronic ignition The W-ZG 1 ignition unit used on all Weishaupt W burners is particularly energy efficient and extremely reliable. Digital combustion management for safety and ease of use Weishaupt is a pioneer in this field. Digital combustion management offers greater ease of use and simple servicing, even greater relaibility in operation, and, last but not least, an extremely attractive price/capacity relationship. Furthermore, this intelligent technology enables the burner to be integrated with complex automation systems. Valve proving as standard with W-FM1 and W-FM2 combustion managers The low gas pressure switch is used to check the tightness of the gas valves, thus providing valve proving without the need for any additional components or costs. Gas multifunction assembly The newly concieved gas multifunction assembly incorporates the following components/functions: Servo-controlled gas pressure governor for continual gas pressure 2 solenoid valves (Class A) Filter Gas pressure switch If the gas pressure falls too low, a low gas pressure program is started. The gas pressure switch also provides for automatic valve proving. Outstanding service Weishaupt has an extensive sales and sevice network worldwide. Customer service is available around the clock. Optimal in-house training at Weishaupt ensures our service engineers are of the highest calibre. Proven quality All burners are tested by an independent body and conform to the following standards and EU directives: EN 676 Gas Appliance Directive 9/96/EEC Machinery Directive 98/7/EC Electromagnetic Compatability Directive 89/6/EEC Low Voltage Directive 7/2/EEC Boiler Efficiency Directive 92/42/EEC WG and WG4 also comform to: Pressure Equipment Directive 97/2/EC The right size Weishaupt burner for every situation 5
Digital combustion management: safe and easy to use All Weishaupt W series burners are fitted with digital combustion managers as standard, whose microprocessors control and monitor all burner functions. The result: Weishaupt burners are easy to use, precise and safe. The digital combustion managers also offer the possibility of communicating with other systems via an integrated ebus port. This enables the heating engineer to monitor the opration of the burner and remotely diagnose any errors. The key points: The utilisation of identical units for gas and oil burners simplifies commissioning and reduces the number of spares required. Non-interchangeable plug connections ensure the correct electrical connection of all components Electrical remote reset is possible Safety ensured with the use of two microprocessors (reciprocal monitoring) Vari-coloured LED lamp to indicate burner operational stage and fault conditions (WG1, WG2 versions LN and Z-LN) LCD display with interrogation, servicing and parameter functions. the burner can be set directly via the operating keys (WG1 WG4 version ZM-LN) Suitable for continuous operation of hot water plant (controlled shutdown and restart every 24 hours) Suitable for air heaters and Group II III, and IV steam boilers (W-FM 21 optional) The integrated ebus interface offers the following functions: Connection to a PC for display of the operational sequence and the setting of function parameters Remote monitoring and diagnosis via a self dialling modem Connection to modern building management systems Prepurge time can be set from a PC via the ebus interface System overview Digital combustion management W-FM 5 W-FM 1 W-FM 2 W-FM 21 Combustion manager for intermittent operation Combustion manager for continuous operation Flame sensor Ion Ion Ion Ion Electronic compound regulation Air and gas Stepping motor Air Removable control unit (max. distance) 1 m 1 m Valve proving Fuel consumption meter available ebus interface Available on burner models WG 1-D WG 1-D WG 1 WG 4 WG 1 WG 4 WG 2-C WG 2-C modulating modulating single stage single stage WG WG 4 WG WG 4 without servomotor with servomotor with speed control with speed control and two stage TRD execution 6

Trustworthy technology Even the visual impression after removing the burner cover is convincing. All components are clearly arranged, the electrical connections are obvious and non-interchangeable. The technology makes a good impression because it is typical Weishaupt. Compact construction The WG burners compact construction means they can be easily installed by one person. Commissioning costs have been reduced to a minimum. Low NO x execution All WG burners are Low NO x execution as standard. A specially designed mixing head produces an intensive internal flue gas recirculation, resulting in exemplary emission levels. Sound attenuated air inlet The transverse fan is sound attenuated on the suction side. These burners therefore operate particularly quietly. Electronically controlled air damper The electronically controlled air damper closes at burner shutdown to hinder the cooling-down of the combustion chamber. Sevicing position A special bracket enables the burner to be put into a servicing position, which enabling easy access to the burner and mixing assembly. Common platform The common platform principle used with W burners simplifies the provision and storage of spare parts. Diagnosis via laptop A special software package and connection cables are available for interrogating the combustion manager. Combustion optimisation and fault analysis can thus be carried out easily via a laptop computer. Speed control (WG and WG 4) Whereas normally a burner motor is operated at a constant speed, speed controlled burners vary the speed of the burner motor dependent on the burner load. The process is controlled by the digital combustion manager. The equipment assures the gas/air compound such that no additional speed monitoring is required. Speed controls offers the advantages of reduced electrical consumption and a considerable reduction in noise levels at partial load. The reduced noise levels can be of particular benefit in the field. A 1 db reduction in the sound level can be achieved at 5% burner load, which equates to a halving of noise emissions. 8
