This jacketed boiler comes with 2 elements, a 2-inch drain valve, thermometers for the interior and the lid of the boiler, and a 1.5-inch sight glass to inspect the heating fluid level. The jacket layer's capacity is around 16 liters; it's recommended to fill 12-14 liters of glycol oil in the jacket. This boiler is not rated for pressure; thus, the PRV is not supplied. We recommend using glycol oil as heating fluid and leaving the filling port open when heating.
Be sure to wrap some Teflon tape around the threads of the thermometers and plug before screwing it to the port.
