IGNITION CONTROLS FOR COMBINED VALVE AND IGNITION SYSTEM
PRODUCTION HANDBOOK
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 S4565, S4575 and S4585 ignition
controls are used in conjunction with the VK41.. series gas
controls to provide and optimised safety sub-system for
programmed safe light up and flame supervision of the main
burner of the appliance
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.
NOTE: The Combined Valve and Ignition (CVI) product concept consists of a specially designed gas valve family in
combination with a dedicated ignition controls family. This product handbook describes the CVI ignition controls family
S4565, S4575 and S4585 for use in combination with the CVI gas control family VK41.. For details of the CVI gas
controls please refer to Product Handbook EN2R-9004. For an up-to-date copy please contact your nearest
Honeywell office. For glossary of terms, abbrevations and symbols see document EN2R-9039

DESCRIPTION
Valves • S4565
The Combined Valve and Ignition (CVI) system controls and Direct Burner Ignition (DBI) or Intermittent Pilot ignition
performs all the functions required for safe ignition, flame (IP) with a defined safety time for applications with or
supervision and for safely regulating the gas flow to the pilot without fan, with flame detection, volatile or non volatile
