Technical characteristics
These boilers are steel, pressurised, horizontal cylindrical type, with flame reversing process in the furnace and a third combustion
flue pass.
They may be used for heating water to a temperature not exceeding boiling point under installation conditions.
The boilers meet the essential requirements of the relevant EC Directives, the laws and standards of the countries of destination
which are indicated on the technical data plate of the boiler.
Installation in any other country can present a danger to persons, animals and/or property.
The boiler is a single-body type, compatible with blown air burners that can work on gas or liquid fuels.
The following models are available:
70 - HR 70, heat output 70 kW
80 - HR 80, heat output 80 kW
90 - HR 90, heat output 90 kW
100 - HR 100, heat output 100 kW
120 - HR 120, heat output 120 kW
150 - HR 150, heat output 150 kW
200 - HR 200, heat output 200 kW
250 - HR 250, heat output 250 kW
300 - HR 300, heat output 300 kW
350 - HR 350, heat output 350 kW
400 - HR 400, heat output 400 kW
500 - HR 500, heat output 500 kW
620 - HR 620, heat output 620 kW
The boilers are fitted with a right- or left-hinged door.
The outer casing is lined with a glass wool layer.
Hooks are fitted to the upper part of the casing for lifting the boiler.
The boilers are fitted with a blind cylindrical furnace in which the centre flame of the burner reverses peripherally forwards: from
there, the combustion gases enter the flue gas ducts. The flue gas is then collected in the smoke chamber at the extremity of the
ducts and sent to the chimney.
While the burner is operating, within the range of output of the boiler, the combustion chamber always remains under pressure.
The boilers are designed to operate either with an ON/OFF burner or with a two-stage or modulating burner, on condition that the
minimum heat output is not lower than the value indicated on the technical data plate for the type of fuel used.
The control panel is designed for managing the CH mode only and it includes:
• Main back-lighted switch
• Burner switch
• CH pump switch
• DHW pump switch
• Indicator lights for:
- Power on
- Heating on
- DHW mode
- Burner on
- Shutdown due to overheating
• Two-stage boiler water temperature regulator (60/90°C) with 8°C difference between 1st and 2nd stage
• Safety thermostat (100°C)
• Minimum thermostat (45°C)
• Thermometer
For DHW management, the control panel can be fitted with the following optional equipment:
• an additional CH pump and a DHW pump
• a water storage heater priority thermostat
• a thermoregulation control unit
• a board for controlling three different CH zones
