Water circulation and plumbing notes The system is designed to operate with a maximum output temperature of 180°F or lower and a temperature rise across the unit of 20°F or lower. Please refer to Table 4 for the recommended flow rate versus the capacity of the boiler. Table 4 Recommended Water Flow Rate vs Capacity Capacity (kW)
The automatic pressure relief valve supplied with the boiler is required to prevent dangerous pressure build-ups in the system in case of system malfunction and may under certain conditions vent hot water. Do not install the system where water could damage rugs, furniture, etc. When piping the relief valve to a drain, check with local authority for recommended method of installation.

Set the thermostat above the room temperature. The system should start. Make sure the pump starts running as soon as the system starts. 9.10 Heating stages will be switched ON in sequence at 5 second intervals, confirmed by green lights on the PC board.
Your boiler is now ready and functional. Installation examples 11.1 Installation A shows a Thermolec electric boiler in a Full-Electric Configuration. 11.2 Installation B shows a Thermolec electric boiler in a FFB-Series Configuration. Water is always passing through both boilers even if only one heat source is selected at a time.
Thermolec’s responsibility shall be limited in any case to the replacement or repair, in its factory or in the field, by its own personnel or by others choosen by Thermolec, at its option, of such boiler or parts thereof, as shall prove to be defective within the warranty period.
