With a specific DHW flow rate of 14.8 L\/min (EN 625), it comfortably supplies a shower and washbasin simultaneously. For larger homes or high-demand properties, consider the Dina 35C.\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails style=\"border: 1px solid #dde8e7; border-radius: 6px; margin-bottom: 8px;\"\u003e\n\u003csummary style=\"background: #008377CF; color: #fff; padding: 11px 15px; border-radius: 5px; cursor: pointer; font-weight: 600; list-style: none;\"\u003eDoes the vertical flue kit cover a standard roof installation?\u003c\/summary\u003e\n\u003cdiv style=\"padding: 13px 15px; font-size: 15px;\"\u003eYes. The included \u003cstrong\u003eVertical Flue Kit (10999.1163.0, Ø 60\/100 mm)\u003c\/strong\u003e provides a roof-exit terminal suitable for pitched or flat roofs with the appropriate flashing plate. For longer vertical runs up to 10 m, additional \u003cstrong\u003e1 m extensions\u003c\/strong\u003e and pipe-support brackets are available from the Biasi flue accessories range.\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails style=\"border: 1px solid #dde8e7; border-radius: 6px; margin-bottom: 8px;\"\u003e\n\u003csummary style=\"background: #008377CF; color: #fff; padding: 11px 15px; border-radius: 5px; cursor: pointer; font-weight: 600; list-style: none;\"\u003eCan the Dina 25C be converted from Natural Gas to LPG on site?\u003c\/summary\u003e\n\u003cdiv style=\"padding: 13px 15px; font-size: 15px;\"\u003eYes — LPG conversion is possible using the appropriate Biasi LPG conversion kit. The \u003cstrong\u003eGas Adaptive Technology\u003c\/strong\u003e also means no recalibration is required after gas-type changes via the CAF (automatic calibration) function in the service menu.

To reach the higher \u003cstrong\u003eA+ classification\u003c\/strong\u003e, a \u003cstrong\u003emodulating room thermostat and an external weather-compensation temperature probe\u003c\/strong\u003e must be fitted.

After a service, the Gas Safe engineer resets the reminder period (typically 12 months) via the Maintenance menu under access code 6683.

Biasi requires the central heating system to be \u003cstrong\u003ethoroughly flushed and dosed with a suitable inhibitor\u003c\/strong\u003e before commissioning. The installation of a \u003cstrong\u003emagnetic filter\u003c\/strong\u003e is also strongly recommended to protect the boiler's heat exchanger and pump.
