GAS CONTROLS FOR COMBINED VALVE AND IGNITION SYSTEM
VK41../VK81..SERIES
APPLICATION
The Combined Valve and Ignition (CVI) system has been
developed for application in gas fired domestic central heating
boilers, combi boilers and warm air furnaces or water heater
appliances with an automatic ignition system.
For this system, the VK41../VK81.. series gas controls have
been designed to have the S4565/S4575/S4585 series
ignition control attached directly on to the valve.
The combined system then provides programmed safe light
up, flame supervision and regulation of gas flow to the main
burner and/or pilot burner of the appliance.
The VK41.5/VK81.5 series gas controls (without pilot outlet)
can also be used alone in direct burner ignition applications.
A plug (order number 45.900.441- ) with integrated rectifier
circuit then has to be used on the gas control.

This reduces the force against the main valve spring allowing the main valve to close The VK4100/VK8100 series gas controls features the positive proportionately. Thus the main valve limits the outlet (or servo system, i.e.
