I just installed a gas fireplace. My hope is to be able to have 2 separate locations for on/off switching as far as the pilot/starter, essentially just a three-way circuit, except that the unit doesn't seem to be wired for that sort of situation. Inside the unit is a complex wiring harness, but the connection for the low-voltage is simple enough. As a trial I connected a 50 foot run of 14G 3-wire to the harness and there's no problem turning it on or off. I'm just not sure how I can connect another switch for a different location. The only wires coming off the harness are a white and a red - the unit came with a ten foot strand of 16 or 18G (something really fragile) wire already connected to the harness, so I just clipped them and connected the 14G, thinking a thicker wire might allow for a longer run and less voltage drop.

Unlike a typical 3-way circuit, the fireplace unit has a separate 110 connection that doesn't seem to have any way of connecting through the 3-way switches.

Any help or insight appreciated.
