Connection of boilers ATMOS F71 ESBE

Connection for systems without accumulation tanks up to 32 kW

Description: Professional stainless steel connection of the boiler based on 35 × 1.5 mm diameter pipe, designed to maintain a minimum temperature of return water to the boiler 70 °C and allowing quick installation using two 6/4“ nipples with a flat seal. The connection includes all the necessary components required by the manufacturer (safety valve 2.5 bar, vent valve, manometer, filter with magnet, two pumps, thermoregulation valve 70 °C, two shut-off valves, manually operated three-way valve).

Info: The connection is designed for quick connection of the boiler directly to the heating system. The connection includes 1“ inputs and outputs for connecting the heating circuit and the boiler for heating domestic hot water (DHW). The connection allows for a more extensive heating system to expand it to two or three heating circuits by purchasing a special manifold and the necessary circulation units with a spacing of 90 mm – 1“ ↑↓ 1“.

The connection type	A height	B Connection depth behind the boiler
ATMOS F71 ESBE (DC18S, DC22S, DC25S, DC30SX, C15S, C18S, AC16S, AC25S)	1668	290
ATMOS F71 ESBE (C25ST + PSC 10 – 30) (C32ST + PSC 10 – 30)	1913	290

Example of connection without accumulation tank
(one heating circuit + DHW heating circuit)
– production design

– pump group ESBE GRA311 with manually operated three-way valve – code: P0533

INFO – With this connection, the hot water boiler is charged directly by the pump in the boiler circuit (we do not need another pump) during boiler operation. The water temperature in the boiler corresponds to the operating temperature of the boiler.
