RELEASING THE ELECTRONIC
DEVICE (fig. 1)
"RS Mk.II" boilers have automatic igni-
tion (with no pilot light) and have an
SM 191. 1 electronic control and pro-
tection device.
The boiler starts when the main swit-
ch (1) is pressed, sending discharge
current to the ignition electrode throu-
gh the programmer while simulta-
neously opening the gas valve.
The burner will normally ignite within 1
or 2 seconds. Various factors may
cause ignition to fail, triggering the
signal which shuts down the boiler (1);
if this occurs, press the release button
(8) and the boiler will automatically
start again.
If the boiler fails to ignite correctly and
you have already pushed the release
button two or three times, request the
assistance of an authorised service
technician.
TURNING OFF THE BOILER (fig. 1)
To turn the boiler off completely, turn
off the power using the main switch (1).
Turn off the gas supply cock if the gene-
rator will not be used for some time.
SAFETY THERMOSTAT
The manually reset safety thermostat
(3, fig. 1) is tripped when the boiler
temperature exceeds 95°C, shutting
