Description
NOVELLA RAP
boilers are gas fuelled boil-
ers for domestic heating. They are equipped
with an atmospheric burner and a cast iron
primary heat exchanger.
They incorporate an open (type B11BS) com-
bustion chamber and are fitted with a hood
that ensures proper flue gas venting even
with a fluctuating flue draught.
They are also equipped with a flue gas
thermostat, as required by applicable safety
standards. The burner is a stainless steel unit
with stabilised flame and smooth ignition. The
flame detection system is of the thermocou-
ple type.
The boiler’s control and safety devices con-
form to applicable technical and safety stand-
ards and are enclosed in a functional control
panel integrated in the body of the appliance
NOVELLA
boilers use total shut-down logic
and do not waste energy because they only
start up when heat is actually needed by the
central heating system (i.e. when the room
thermostat trips).

boilers can be connected to a
storage cylinder to produce domestic hot
water, and can be equipped with temperature
controllers in the form of specific accessories.
Installation, maintenance and access to inter-
nal components is facilitated by a large front
panel.
The
key features
of these boilers include:
- piezoelectric ignition with thermocouple
flame control
- gas supply solenoid valve with built-in pres-
sure stabiliser and double shutter for burner
control
- central heating circuit temperature control-
ler
- central heating circuit temperature gauge
- provision for room thermostat or timer.
