WGL30 / 40 dual-fuel burners with optional O2 trim W-FM 25 combustion manager Dual-fuel mixing assembly Fuel selection switch Multi-function assembly with two solenoid valves, regulator, and filter Air inlet housing Oil hoses Air damper actuator Gas butterfly actuator Control and display unit Oil pump with separate motor

BERGER LAHR D - 77901 Lahr Conceptual drawing of WGL30 / 40 with O2 trim The key points: • Sliding-two-stage or modulating load control when firing on gas, two-stage load control when firing on oil • W-FM25 O2 for O2 trim • The separately motorised oil pump is decoupled while the burner is firing on gas • Fuel changeover via selection switch or field bus module • Non-interchangeable plugs ensure the correct electrical connection of all components • Safety is ensured by the reciprocal monitoring of two microprocessors • Fully electronic control and diagnosis • Flame monitoring via KLC/FLW infrared...

2) With EM3/3 expansion module 3) With EM3/2 expansion module Weishaupt is a pioneer in this field. Digital combustion management offers greater ease of use, simple servicing, even greater reliability in operation, and, last but not least, an extremely attractive price to capacity ratio. Furthermore, this intelligent technology enables the burner to be integrated with complex building management systems. All of Weishaupt's W-series burners are fitted as standard with a digital combustion manager. The unit's microprocessors control and monitor all burner functions. As a result, Weishaupt burners...

- Configurable inputs (summary) Socket 12 - Proof of valve closure (POC) - Remote reset - Start release - Contact-dependent post-purge Socket 15 - High gas pressure switch - Extraneous air pressure switch By way of example, the following data can be read or changed: - Fuel changeover - Current degree of modulation - Required degree of modulation - Heat demand present - Flame signal - Hardware inputs and outputs - Operating phase - Actuator positions - Fuel throughputs Input: Required burner load 0-20 mA / 4-20 mA 0-10 V / 2-10 V Output: Current burner load 0-20 mA / 4-20 mA 0-10 V / 2-10 V

• Two-term switching (e.g. temperature or pressure stat) causes actuators to drive the burner to partial load or full load in response to heat demand. Single-stage control with low-impact start can also be effected. Load control Mark Capacity Size Fuel 2 Fuel 1 Burner series

Class D gas oil per BS 2869 / IS 251 Class A2 gas oil per BS 2869 / IS 251 10 % biodiesel blends (B10) The suitability of fuels of differing quality must be confirmed in advance with Weishaupt. Weishaupt WGL30 and WGL40 burners with W-FM 25 combustion manager are suitable for intermittent firing on: - LTHW boilers - Group II and III steam boilers - Certain process applications - Ambient temperature - Maximum 80 % relative humidity, no condensation - The combustion air must be free of aggressive substances (halogens, chlorides, fluorides etc.) and impurities (dust, debris, vapours, etc.) - Adequate...

The burner capacity graphs are certified in accordance with EN 676 and EN 267. The stated ratings are based on an air temperature of 20 °C and an installation at sea level. For installations at higher altitudes, a reduction in capacity of 1 % per 100 m above sea level should be taken into account. The combustion chamber pressure of the heat generator must be added to the flow pressure determined from the chart when sizing the gas valve train. Minimum flow pressure 15 mbar. Minimum 125 kW full-load firing rate for two-stage operation The LHV is referenced to 0 °C and 1013 mbar atmospheric. * The...
