Setup, Compatibility & Care

Installation must be performed by a Gas Safe registered engineer (or local equivalent) to ensure safety and warranty validity. The unit is designed for wall mounting and is pre-configured to be space-efficient, though adequate clearance must be left for maintenance access. For compatibility, ensure your existing gas supply lines and heating loop pressure are assessed by a professional. Care involves an annual service by a qualified technician to verify the `MatriX-Plus` burner state and check for any system debris. Users should monitor the LED display for any service codes and ensure the system pressure remains within the manufacturer-recommended range, typically indicated by the integrated pressure gauge.
