DESCRIPTION
GENERAL DESCRIPTION
• Model N is a single boiler (heating).
• Equipment required: a water connection kit for the heating circuit
supply (optional).
• The N-Mini control panel includes a control thermostat and a
thermostat pressure gauge.
• The control panel on N 1 - 2 - 3 boilers includes a main switch,
a Summer/Winter switch, a thermostat pressure gauge, a control
thermostat and a manual reset high-limit thermostat.
• The N boiler can be connected directly to the chimney using a
B23 chimney connector.
• N-Mini Model: output of 16.6 kW.
• N1 Model: Outputs in the range 20 to 25 kW.
• N2 Model: Outputs in the range 28 to 36 kW.
• N3 Model: Outputs in the range 36.5 to 51 kW.
OPERATING PRINCIPLE
Simple to control, safety assured
The temperature of the water in both the heating circuit and the hot
water circuit is regulated by a single control. This is achieved by
means of the control thermostat and the bulb is located beside the
boiler outlet. switch.
• A manual reset high-limit thermostat locks the burner if the
primary water temperature reaches 103°C.
• A minimum thermostat, fitted at the rear of the boiler, and preset
at 45°C, delays the activation of the boiler pump. This prevents
any risk of corrosion in the combustion chamber.
Generation of domestic hot water
Boiler N can be combined with the NHR tank (110 L) superimposed
with the boiler or with any other ACV tank.
DESIGN CHARACTERISTICS
Outer body
The outer body which holds the primary water is made from STW 22
heavy gauge steel.
Flue ways
The boiler’s flue ways can be accessed from the front and include
a set of removable turbulators, in either stainless steel or chrome,
which have been specially designed to provide the optimum
combustion efficiency.
Combustion chamber
The boiler features a large, water-cooled combustion chamber to
guarantee a good flame.
Removable burner chamber plate
The chamber plate is fitted on a hinge (left or right) and made from
STW 22 steel. It is protected from the flame by a ceramic fibre
padding and a vermiculite brick.
Insulation
The burner body is insulated with rock wool padding (50mm thick).
Casing
The boiler is covered with a steel casing that has been stove enamelled
at 220°C after scouring and phosphating.
