DESCRIPTION

Valves
The Combined Valve and Ignition (CVI) system controls and
performs all the functions required for safe ignition, flame
supervision and for safely regulating the gas flow to the pilot
and/or main burner.
The CVI consists of a gas valve of the VK41.. series and a
dedicated ignition control of the series S4565, S4575 and
S4585 which is connected directly on to it.
Ignition control
The S4565, S4575 or S4585 220/240 Vac series ignition
controls can be directly electrically connected to a VK41..
series gas control. (S4575 can also be rated 110 ... 120Vac)
The S4565/S4575 ignition controls are not intended for direct
exposure to flame envelope.
S4565, S4575 and S4585 ignition controls give excellent
performance and a high reliability standard. There are
versions available for different ignition systems:
The S4565/S4575 ignition controls are approved on the
North American standard ANSI Z21.20 Automatic Ignition
Systems.
S4565, S4575 and S4585 systems function in accordance
with EN 298.
•
S4565
Direct Burner Ignition (DBI) or Intermittent Pilot ignition
(IP) with a defined safety time for applications with or
without fan, with flame detection, volatile or non volatile
lock out, optional remote reset, fixed waiting times and in
case of flame failure recycling of the full start up
sequence.
•
S4575
Hot Surface Ignition (HSI) with a defined safety time for
applications with or without fan, with flame detection,
volatile or non volatile lock out, optional remote reset,
fixed waiting times and in case of flame failure recycling of
the full start up sequence.
•
S4585
Intermittent Pilot ignition (IP) for atmospheric or fan
assisted applications with the so called "wild pilot system"
without safety time for ignition, with flame detection on the
pilot flame. Wild pilot system means a safety T
applicable for pilot burners up to 250 Watt
Intermittent Pilot ignition (IP) for atmospheric or fan assisted
applications with the so called "wild pilot system" * without
safety time for ignition and flame detection on the pilot flame.
The performance and the construction of the ignition control
is optimized and dedicated to the VK41.. series gas controls.
