I have a fireplace that has 2 speed fans that circulate air around the outside of the fireplace. I want to relocate the switch on one because you have to crawl under furniture to turn it on (the switch in on the fan). 3 wires (green blue and black) go to the switch. I'm going to a 2 switch standard wall switch. I'm not concerned about having 2 speeds - hi is all I use. Do I need to connect just the blue & black to get this or do I need to connect blue and green together and black on the other side?

If the fan and switch are part of the fireplace, tampering with the desgin will violate the UL listing of the unit.

If there is a future problem with the fireplace and a houes fire results, you could end up with a voided home owner's insurance policy.
