If you look at the Schematic, you will see, on the left side:

1. A pair of terminals (X1-1 and X1-2) labelled "thermostat"
2. A pair of terminals (X2-1 and X2-2) labelled "boiler"

Boiler terminals X12-1 and X12-2 are labelled OT (OpenTherm)

Connect X2-1 and X2-2 of the Gateway to X12-1 and X12-2 of the boiler (any way round)

Connect your Opentherm thermostat to X1-1 and X1-2 of the Gateway (any way round)
