ensures constant and efficient
extraction of products generated by
combustion;
– to prevent the wind from creating
pressure zones around the chim-
ney top greater than the uplift
force of combustion gases, the
exhaust outlet should be at least
0.4 m higher than structures adja-
cent to the stack (including the
roof top) within 8 m;
– have a diameter that is not inferior
to that of the boiler union: square or
rectangular-section flues should
have an internal section 10%
greater than that of the boiler union;
– the useful section of the flue must
conform to the following formula:

ELECTRICAL CONNECTION

The boiler is fitted with an electricity
cable, and requires a a single-phase
power supply of 230V - 50Hz through
the main switch protected by fuses.
The room thermostat (required for
enhanced room temperature control)
should be installed as shown in fig. 6.
Connect the burner and system circu-
lation pump power cables supplied.

NOTE: Device must be connected to
an efficient earthing system. SIME
declines all responsibility for injury
caused to persons due to failure to
earth the boiler. Always turn off the
power supply before doing any work
on the electrical panel.
2.5. 1 RVA 43.222 climat controller
All functions of the boiler may be con-
trolled using the controller, optional
code 8096303, which is supplied with
an outdoor temperature probe (SE)
and a boiler immersion probe (SC). The
controller is installed in the control
panel in place of the relating cover (fig.
6). The controller is to be connected to
an additional series of low voltage con-
nectors for connection of the room
temperature control unit (the connec-
tors are supplied in a bag inside the
control panel).
The probe bulb of the external hot
water tank, if any, (SS) code 6277110,
must be inserted in the hot water tank
sheath, while the bulb of the boiler
probe (SC) must be inserted in the boi-
ler sheath. When assembling the out-
door temperature probe, follow the
instructions provided in the probe
package. Refer to fig. 5 for wiring
instructions.
IMPORTANT: To make sure that the
unit works properly, set the boiler con-
trol thermostat as high as it will go.

NOTE: When connecting the room stat (TA) remove the bridge
between terminals 20-21. When connecting the timer pro-
grammer (OP) remove the bridge between terminals 30-31.
When connecting the RV 43.222 unit remove the bridge
between terminals 20-21 and remove the relay (R).
NOTE: The brown (capped off)
cable has to be exclusively used
in case of permanent feeding
burners (type B1).
