Technical Specifications:
The document provides detailed specifications for three boiler models: CS5-CT300, CS5-CT400, and CS5-CT500. Key dimensions are listed in millimeters, including parameters such as A, C, D, E, F, G, H, N1, R32, Q23, T14, T24, T34, and ØZ. The boilers have varying weights, with the CS5-CT300 weighing 3130 kg, CS5-CT400 at 3530 kg, and CS5-CT500 at 3930 kg.

Performance and Operating Conditions:
The boilers operate with a maximum hydraulic test pressure of 4.5 bar and a maximum operating pressure of 3 bar. The nominal thermal efficiency is declared at 92% for all models. The nominal output power is 294 kW for CS5-CT300, 399 kW for CS5-CT400, and 491 kW for CS5-CT500. The maximum operating temperature is 90°C, and the minimum temperature for pump activation is 50°C.

Fuel and Consumption:
The boilers are designed to use wood pellets as fuel, in accordance with the EN 303-5:2012 standard. The maximum fuel consumption rates are 68.1 kg/h for CS5-CT300, 91.9 kg/h for CS5-CT400, and 113.4 kg/h for CS5-CT500. The hopper capacity is 600 kg, with autonomy ranging from 5.3 to 8.8 hours depending on the model.

Environmental and Safety Standards:
The boilers comply with Class 5 of the EN 303-5:2012 standard. Emissions at nominal heat output include dust levels of approximately 18.9 mg/Nm3 and CO emissions ranging from 0.077 to 0.132 g/Nm3 at 13% O2. The average smoke temperature at nominal heat output is 175°C with a ±20% variance.

Hydraulic and Electrical Connections:
The document specifies hydraulic connections, including inlet and outlet water sockets, and mentions a flue draught depression of -20 Pa. The boilers require a voltage of 380 V (50 Hz) for operation.

Maintenance and Modifications:
The document notes the minimum space required for maintenance activities, such as auger extraction. Pasqualicchio reserves the right to make technical, dimensional, and aesthetic modifications to improve products without prior notice.
