Connection of ATMOS boilers

Connection of ATMOS boilers up to 40 kW with manual stoking

Professional stainless steel connection based on 35 × 1.5 mm diameter pipe, designed to maintain a minimum temperature of return water to the boiler and quickly connect the boiler using two 6/4“ flat seal fittings. The connection includes all the necessary components required by the manufacturer (safety valve 2.5 bar, vent valve, manometer, two pumps, two shut-off valves, three-way valve and, for variants F3 and F4, two servo actuators).

The connection is ready to connect the boiler directly to the heating system or to connect the boiler to accumulation tanks. In the case of a larger heating system, the connection can be extended to two or three heating circuits by purchasing a special distributor and the necessary pump group.

ATMOS F1 Laddomat / ATMOS F2 Laddomat

1 – outlet (of hot water) to the heating system
2 – return from the heating system
3 – (hot water) inlet from the accumulation tank to the pump group of the heating circuit (when connecting without accumulation tank, it is necessary to block it off)
4 – return to the accumulation tank from the pump group of the heating circuit (when connecting without accumulation tank, it is necessary to block it off)
5 – hot water outlet from the boiler to the accumulation tank (when connecting without accumulation tank, it is necessary to block it off)
6 – return from the accumulation tank to the boiler (when connecting without accumulation tank, it is necessary to block it off)
7 – safety set (safety valve 2,5 bar, vent valve and pressure gauge)
8 -ESBE GRA211 pump group with manually operated three-way valve for one heating circuit
9 – Laddomat X22 for one boiler circuit (with special ball valves)
10 – pump in the boiler circuit (part of Laddomat X22)
11 – thermometers (part of Laddomat X22)
12 – ball valve fitting – male thread (part of Laddomat X22)
13 – ball valves for switching when connection with and without the accumulation tank (for flow adjustment)
14 – expansion tank output (1“)
