Fireplaces, Heating Stoves, Flues and Chimneys - remote control for fireplace

I have a gas fireplace that came with our townhouse.
It is about 10 years old (as is the house).

To turn on the gas fireplace, there is a simple on/ff light switch.

I have a Harmony Universal remote, and I'd like to put an IR remote onto the fireplace. I'd like to just replace the simple on off switch, as I don't think I'd be able to redo the whole thing.

Could I just switch the light switch with something like this?
Programmable Touchless Light Switch - Smarthome (http://www.smarthome.com/2034WS/Programmable-Touchless-Light-Switch/p.aspx)

or

IR-Controllable Wall Switch - 21110 - Smarthome (http://www.smarthome.com/2035IR/IR-Controllable-Wall-Switch-21110/p.aspx)

You may be able to use the Harmony remote, if it has a learning feature. You will have to purchase an IR remote for your fireplace and program the Harmony to replace the transmitter that comes with the remote.

Yup. Thats my plan. I just want to make sure I can use the switches.

I'm not an Electrician, but if I were doing this I would look for a switch that is not a dimmer. I would look for one that is a simple on/off switch. I'm not sure how the dimmer function could or would hurt the electrical componants of the fireplace. Again I'm not an electrician this is just my 2 cents. My some else who knows more and expand on or dispute my thought.

The dimmer factor did occur to me, which is why I have had a hard time find a simple on/off IR remote.

The first option I mentioned seems to be the best one.
