Dimensions For this system, the VK4105G series gas control has been See fig. 1. designed to have the S4565.M series ignition control attached directly onto the valve. Maximum capacity The combined system then provides programmed safe light 2.5 m3/h air at Dp = 3 mbar up, flame supervision, regulation and modulation of gas flow to the main burner of the appliance. Minimum capacity Subject to change without notice. Printed in the Netherlands. DESCRIPTION The minimum rate is adjustable with a throttling screw from 0.2 m3/h air up to 0.92 m3/h air at Dp = 17 mbar The CVI--m system comprises a modulating gas control with on/off regulating and modulating function and an ignition Outlet pressure range control with integrated power supply for the electric 1.5 ... 32 mbar modulating operator. The gas control holds a first electric on/off direct operator for Minimum rate range opening the safety valve of class B according to EN 161 and 1.5 ... 7 mbar max a second electric on/off servo operator of class J according Maximum inlet pressure to EN 161 for opening the main valve. 60 mbar The second electric operator also includes the modulation function. Modulation characteristics The minimum gas flow can be set by means of an adjustable In fig. 2. and 3. the modulating performance of the CVI--m throttle. system is reflected at 20 mbar and 37 mbar. The pressure regulator controls the maximum setting and is in accordance with class B requirement of EN 88. Closing time The S4565.M ignition control provides automatic ignition for < 1 second direct gas burner applications. The power supply for the modulating current is generated by Mounting holes the ignition control. Two mounting holes at the bottom for thread forming screws.
