Cleaning And Maintenance - Sime RS Mk.II Serie Instrucciones Para El Instalador Y El Usuario

– In the event of malfunctioning or breakdown, turn off the boiler, and do not attempt to repair it yourself. Contact your local authorised
technical service centre.
– Boiler installation and all other service and maintenance operations must be performed by qualified personnel. Never tamper with any
of the devices which the manufacturer has sealed.
– Never obstruct the air intake grids or the ventilation openings in the room in which the boiler is installed.
TURNING ON AND OPERATING THE BOILER
TURNING ON THE BOILER (fig. 1)
To turn on the boiler, simply set the control
thermostat knob (5) to 60°C and press the
main switch (1); the boiler will start auto-
matically.
WARNING:
When the gas pressure is insufficient,
the burner immediately turns off and the
insufficient gas pressure warning signal
is enabled (2). In this event, the boiler
cannot be started again using the release
button (6) for safety reasons. The boiler
will automatically start again when the
minimum pressure required by the gas
pressure switch (10 mbar) is restored.
HEATING TEMPERATURE CONTROL (fig. 1)
Temperature may be controlled using the
thermostat knob(5) within a range of 40 to
85°C. To ensure optimal performance of
the generator, do not go below a minimum
operating temperature of 60°C; this will
prevent formation of condensation which
could cause the cast iron body to deteriora-
te with time.
RELEASING THE ELECTRONIC
DEVICE (fig. 1)
"RS Mk.II" boilers have automatic ignition
(with no pilot light) and have an SM 191. 1
electronic control and protection device.
The boiler starts when the main switch (1)
is pressed, sending discharge current to
the ignition electrode through the program-
mer while simultaneously 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.

TRANSFORMATION FOR USE OF
ANOTHER TYPE OF GAS
If it is necessary to transform the boiler to
burn a different type of gas, contact autho-
rised SIME technical service personnel.
CLEANING AND
MAINTENANCE
At the end of each heating season, it is
essential to have the boiler thoroughly
checked and cleaned out.
Preventive maintenance and checking of
the efficient operation of the equipment
and safety devices must be carried out
