APPLICATION EN 126 group 1
The VK4105G and S4565.M, Combined Valve and Ignition Pressure feedback connection
modulating system (CVI--m) have specially been developed M5 connection on pressure regulator on maximum setting.
for application in gas fired appliances with direct burner
ignition that require electric modulating control of the gas Ambient temperature
input like instantaneous hot water combi boilers and air --15 ... 60 _C
heating appliances. 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.
