Does anyone know which gas fireplace models can be controlled via C-Bus and how (I presume you will need to set it up as a switch, run pink cable, etc) ? Alternatively - which models can be controlled directly by M1 (this will require a slot for a relay I suppose)? Google reveals only 2 models (Realflame Captiva and Jetmaster 850), but neither provide any meaningful details (and the sale folks need a bit of flame under their arses) Thanks heaps
