2.2 INSTALLING THE BRIDGE
Before installing, disconnect the power to the boiler. Remove the front of the BRIDGE by prying with a screw-
driver at point A. Then, with the set of fastening screws supplied, secure the back of the BRIDGE making sure
to run the 2 wires, coming from the boiler, inside the rectangular hole at the bottom (near the terminals). Use the
terminals "OT" for the electrical connection. If the telephone contact (voltage-free contact) has to be connected,
use the terminals "GSM".
Refit the front of the BRIDGE.
