BOILER IGNITION
(fig. 1)
To ignite
“RS”
boilers, just set the
knob of the regulating thermostat (5)
to 60°C and press the main switch
(1), and the boiler will start working
automatically.
CAUTION:
When the gas pressure is insuffi-
cient, the burner will immediately go
out, and the equipment “lock out”
signal (6) will be activated along with
the red warning light for insufficient
gas pressure (2).
Should this happen, for reasons of
safety, the boiler cannot be started
up again by pressing the equipment
deblocking button (6).
The boiler will ignite again automati-
cally once the minimum pressure of
10 mbar set by the gas pressure
switch is restored.
HEATING TEMPERATURE
ADJUSTMENT
(fig. 1)
The heating temperature can be adju-
sted by turning the knob of the ther-
mostat (5), which has a range of
between 40°C and 85°C.
To ensure optimal boiler efficiency at
all times, we recommend not to drop
below a minimum working temperatu-
re of 60°C.
In this way, any formation of conden-
sate that might cause deterioration of
the cast-iron body over time will be
avoided.
DEBLOCKING OF ELECTRONIC
EQUIPMENT
(fig. 1)
The
“RS”
boilers are of the automatic
ignition type (without pilot).
As a result, they are equipped with an
SM 191.1 control and protection elec-
tronic programmer.
When the main switch (1) is pressed,
the boiler will start operating, sending,
via the programmer, a discharge cur-
rent to the ignition electrode and simul-
taneously opening the gas valve.
Ignition of the burner normally takes
place within 1 or 2 seconds.
For various reasons, the boiler may fail
to start, with consequent activation of
the equipment “lock out” signal. In this
case, press the push-button (6) for the
boiler to start up again automatically.
If after two or three deblocking
attempts, the equipment does not go
through the ignition cycle correctly, call
the authorized technical staff.
TURNING OFF BOILER
(fig. 1)
To turn off the
“RS”
boiler completely,
cut off electricity supply to the equip-
ment by operating the main switch (1).
Close the gas-feed pipe tap if the boiler
remains inoperative for a long period.
SAFETY THERMOSTAT
The safety thermostat (3 fig. 1) is of
the manually resetting type and opens,
causing the main burner to turn off
immediately, whenever the temperatu-
WARNINGS
–In case of fault and/or incorrect equipment operation, deactivate it, without making any repairs or taking any direct
action. Contact the authorised technical staff.
–The installation of the boiler and any servicing or maintenance job must be carried out by qualified personnel. Under
no circumstances, the devices sealed by the manufacturer can be tampered with (pr EN 89).
–It is absolutely prohibited to block the intake grilles and the aeration opening of the room where the equipment is
installed.
