Many fireplace remote controls use a simple remote system that utilizes a radio frequency to turn on the fireplace. This is similar to the way a TV remote control works. The signal is activated and the radio signal is sent through the air. The receiver translates the signal and then turns on the fireplace. Most remotes use RF (radio frequency) transmitters and receivers.
How it Turns on the Heat
Once the signal is received the fireplace begins a cycle. The gas comes on at a low volume; the pilot light fires to light the gas. The remote can also control the level of gas that is in the fireplace. A stronger flow of gas makes the fire larger and increases the heat. It is the same as turning a nob to increase the flow of gas in a heater or standard gas fireplace.
Types of Remotes
Many fireplaces come with a remote receiver built in. Today, that option is almost standard because people enjoy the convenience of a remote controlled device. You can also install a receiver and transmitter in a fireplace. These add-on units include both the transmitter and receiver together, so there is not programming required. That is because each receiver makes use of a unique radio signal.
