NIKE MINI 24-28 Export
Compact instantaneous wall-hung conventional
flue boiler (type B).
NIKE Mini 24
NIKE Mini 28
NIKE Mini is a wall-hung conventional flue boiler for heating
and producing domestic hot water and is distinguished by its
compact size.
It is available with an output power of 24 kW (20,640 kcal/h)
and 28 kW (24,080 kcal/h).
A microprocessor controlled electronic board adjusts and
controls the appliance (burner ignition, temperature adjustment,
flame modulation and diagnostics) and the operating parameters
can be displayed and set by means of a digital interface with
display panel and push buttons.
With the new electronics the boiler can be connected to the
Remote Digital Control for controlling the boiler remotely
with the utmost ease and also integrates the timer/room
thermostat, boiler diagnostics and delivery temperature ther-
moregulation functions.
e boiler is fitted with a safety antifreeze system as a
standard feature that protects it against temperatures as low
as -5 °C.
e hydraulic circuit is equipped with a copper water-gas
exchanger, a pump unit in a composite material and a new
electric 3-way valve unit that, according to requirements, allows
the boiler water to circulate in the central heating system or
in a stainless steel plate exchanger for the instant production
of domestic hot water; the primary circuit also features an
automatic by-pass and a 3-bar safety valve.
General features.

NIKE Mini 24 S Export
Compact, wall-hung conventional flue boiler for
central heating only (type B).
NIKE Mini 24 S
NIKE Mini S is a wall-hung conventional flue boiler for central
heating only with an output power of 23.6 kW (20,296 kcal/h)
which, using an optional kit comprising a 3-way electric valve
and a domestic hot water probe together with the necessary
wiring (that can be connected directly to the integrated board),
can be combined with a separate storage tank to produce
domestic hot water.
A microprocessor controlled electronic boards sees to adjust-
ing and controlling the appliance (burner ignition, temperature
setting, flame modulation and diagnostics) which, by means of a
digital interface complete with display and push buttons, lets
you see and adjust the operating parameters.
With the new electronics the appliance can be connected
to the Remote Digital Control for controlling the boiler
remotely with the utmost ease and also integrates the timer/
room thermostat, boiler diagnostics and delivery temperature
thermoregulation functions.

standard feature that protects it against temperatures as low
as -5 °C.
e hydraulic circuit is equipped with a copper water-gas
exchanger, a pump unit in a composite material and a delivery
manifold on which an automatic by-pass and safety valve,
calibrated at 3 bar, are housed.
