IGNITION CONTROLS FOR COMBINED VALVE AND IGNITION SYSTEM

INSTRUCTION SHEET

”Old”-- style

APPLICATION

The Combined Valve and Ignition system (CVI) has specially
been developed for application in gas fired appliances with
either intermittent pilot or direct burner ignition.

For this system, the VK41../VK81.. series gas controls have
been designed to have the S4565/S4575/S4585 series
ignition controls attached directly onto 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.

DESCRIPTION

The S4565/S4575 ignition controls provide automatic ignition
for direct gas burner applications and for intermittent pilot gas
burner applications with safety timer.

The S4565/S4575 ignition controls are not intended for direct
exposure to flame envelope.

The S4585 ignition controls provide automatic ignition for
intermittent pilot gas burner applications without safety timer.

The S4565/S4575/S4585 ignition controls are designed to
meet the european standards:

EN 298: Automatic gas burner control systems.
EN 60730--1: Automatic electrical controls for house hold

and similar use.

The S4565/S4575/S4585 ignition controls can be used in
appliances according European standard for household
electrical requirements EN 60335 series.

The S4565/S4575 ignition controls are approved on the North
American standard ANS Z21.20 Automatic Ignition Systems.

NOTE: S4565SD is not an ignition control but an ignition

circuit and rectifier only

SYSTEM OPERATION

General

Lock- out reset

The S4565 ignition control can be reset by either depressing
the internal/external reset button (suffix A and B) or by
interrupting the permanent life (suffix P and Q).

NOTE 1.: If during normal use the reset button is pressed,

the gas valves drop out and the S4565 ignition
control starts a new sequence after releasing the
reset button.

NOTE 2.: If permanent alarm output:

neon indicator with integral resistor >150 kτ

Εmax 1 mA)

NOTE 3.: If an return high limit thermostat is used, the high

limit switch in the application needs a longer return
time than the trial for ignition time of the control.
This in order to provide non volatile lock out.
