The remote receiver can be either wall-mounted in a standard plastic switch box (not metal) or placed on or near the fireplace hearth. Preferably, the remote receiver should be wall-mounted in a plastic switch box, as this will protect its electronic components from the heat produced by the gas appliance.
A gas fireplace insert typically includes a firebox, burner system, and ignition mechanism. The firebox houses the flame, while the burner distributes gas. An ignition system, either electronic or standing pilot, starts the fire. Decorative elements like faux logs or glass beads enhance aesthetics.
The cooler air from your living space is drawn into the lower vent of the fireplace. It travels around the firebox, and as it does so, it picks up heat, rises and then exits through a top fireplace vent. In some gas fireplaces, an electric fan helps to circulate the warming air.
The firebox is the open-to-the-room, inner section of the fireplace where you light and burn fires. As the name suggests, a firebox has a standard box-like shape. It features a flat base, three walls, and an opening at the front and top.
One of the most common problems faced by homeowners with gas fireplaces is the pilot light going out or not staying lit. The pilot light is a small flame that ignites the gas burner, which produces the heat for your fireplace — if the pilot light goes out, your fireplace won't work.
There is a low battery indicator built into the transmitter. A red LED flash will blink once every 4 second indicating the battery level is low.
Control Panel: Many gas fireplaces have a control panel at the base, where the battery compartment is hidden behind a small door.
Replace the batteries in the remote and receiver box and attempt to re-sync the unit. In the event of corroded batteries, you may need to replace the system. The receivers slide switch is not in the right position. Move the slide witch to the “Remote” position and attempt to use the fireplace remote again.
Outside of that though, virtually all gas fireplaces that I'm aware of have battery backups as standard equipment, although there are a few that offer it only as optional. If emergency heat is important to you, make sure to let your dealer know that you need that, so they can recommend the right fireplace for the job.
Most modern gas fireplaces come with a specialized control panel that manages the fixture's pilot light. For aesthetic purposes, you'll typically find this panel hidden behind the fireplace's front screen, which you can open or remove to gain access.
A transmitter is often a light-emitting diode (LED) which is built into the pointing end of the remote control handset. The infrared light pulses form a pattern unique to that button. The receiver in the device recognizes the pattern and causes the device to respond accordingly.
Faulty thermostat, thermopile, or thermocouple.
Depending on the age of your unit, you'll have a thermostat or thermopile between your gas valve and pilot light that contributes to ignition. If it's loose or faulty, or if your thermostat is malfunctioning, it may prevent your fireplace from turning on.
Common causes include problems with the pilot light, thermocouple, gas supply, obstructions, ignition system, gas pressure, and weather conditions. While some issues can be resolved with basic troubleshooting, others may require professional assistance.
Turn the ON/OFF/PILOT knob to the 'OFF' position and wait for five minutes to clear out any residual gas. After waiting, press and hold the ON/OFF/PILOT knob. Then, press the igniter button repeatedly (as per the manual's instructions, usually for about 30 seconds) until the pilot ignites.
But in general, an efficiently running modern gas fire kept clear of dust and debris should hit or exceed that 10 to 15-year mark before showing signs of wear. Older or cheaper models may start to struggle after 7–8 years. Regular servicing and maintenance will be essential to maximising lifespan potential.
Gas fireplace repair costs can range significantly from $400 to $1500, depending on the problem you face.
Your gas fireplace could be turning off for several reasons. The most like culprits are likely tied to some kind of problem with your setup. Anything from issues with your pilot light, clogged ports on burners, damage to heating components, and thermocouple/thermopile malfunctions can be to blame.
Firebox Replacement
Homeowners pay between $350 and $2,500 for firebox replacements. The price mostly depends on the firebox type. Prefab metal fireboxes can be replaced relatively cheaply, but stone fireboxes that must be replaced or rebuilt cost more because of the extra materials and labor.
A fireplace insert, or firebox, is a fireproof compartment typically surrounded by steel or cast iron, with some featuring insulated glass fronts. Their primary role? To enhance heat retention.
