To change propane fireplaces to natural gas requires that you purchase a conversion kit from the company that manufactured your fireplace. The kit comes with fittings and the flow regulator parts, gaskets and compression springs you will need to modify the fireplace regulator unit.

So you cannot use a Natural Gas burner with Liquid Propane or visa versa. Liquid Propane is heavier than air, so if you do not close a manual valve tightly, the gas will puddle inside the fireplace and flow into the room, creating an dangerous situation.

Answer: Unfortunately, there is no way to convert a ventless fireplace into a vented fireplace. Ventless fireplaces are not designed to have a vent added to them. Your only alternative is to tear out the existing ventless fireplace and replace it with a vented fireplace.

You can get propane hearths in many forms. They’re available as freestanding stoves, built-in fireplaces and sealed fireplace inserts that can be directly installed in your existing mantle. That kind of flexibility lets you enjoy all the benefits of a propane fireplace, whether or not you have a fireplace already.

Efficiency: A propane fireplace runs at around 80 percent efficiency. That makes it four to five times more efficient than a wood fireplace.

That’s why they should never be left running for more than two or three hours at a time and the rooms they are in should always be well-vented themselves.

A propane fireplace should always be vented outside. Failure to properly vent a fireplace causes the carbon monoxide to pour into the home instead of outside and can result in carbon monoxide poisoning and death in a matter of minutes. Yes, gas fireplaces are one potential cause of carbon monoxide poisoning.

Leaving the gas on keeps this compound moving out of the tubes. Keeping the pilot light on will also keep moisture out of the unit and in turn, help prevent corrosion. As you can see, it’s probably best in most cases to extinguish the pilot light in your gas fireplace during the months when you don’t need heat.

If you get dust in the pilot assembly and the pilot needs to be cleaned out, it produces a “lazy” flame, which will be disturbed by the draught of the main burners. The flame lifts away from the thermocouple and causes the temperature on the tip of the thermocouple to drop. This, in turn, makes the gas valve shut off.

Perhaps the most important reason to turn off gas fireplace pilot light in summer is because of the money and energy you will be saving. If you leave the pilot light on during the summer it is simply sitting there burning gas, which is wasting gas and contributing to an exorbitant energy bill.

The pilot light burns significantly less fuel than a fire but it can cost $8 to $10 a month if your fireplace is fueled by natural gas. If your fireplace is fueled by propane, it could cost up to $20 a month. Turning off the pilot would reduce your energy costs during the summer.

As the weather warms up, it is time to put your gas fireplaces and furnaces to rest for the summer. Since it will be several months before you need to fire up the heat again, it is worth considering turning off your system’s pilot light.

Often a gas fireplace has a millivolt generator which is in the path of the pilot flame. It is about the size of an AA battery and is wired to the switch and gas valve. If the millivolt generator is old and weak, or if the pilot flame is weak and wavering, the main burner will go on and off.

Estimated Cost: $10 to $20; What You’ll Need. The thermocouple on your gas furnace is a heat-sensitive device that transmits a small electrical signal to the gas valve to keep it open when the pilot is on.

Your “beeping” fireplace is telling you something: It’s time to replace batteries! The receiving unit will need fresh batteries more frequently than the remote control. Change these batteries along with the batteries in your smoke alarms.

Easy DIY Fix: Gas Fireplace Won’t Stay Lit

1. Before You Begin: Is Your Pilot Light Lit Inside Fireplace?
2. The Fix: Pilot Light to Gas Fireplace Won’t Stay Lit.
3. Check Your Thermopile Output with the TH/TP Contacts.
4. Don’t Replace Your Thermopile or Thermocouple Right Away.
5. Cleaning the Thermopile.
6. Re-test the Cleaned Thermopile.

Check burner ports and the fuel orifice for blockages and keep them clean. Dirty burner ports can also cause burner backfires so be sure to clear away even the smallest debris. If your gas fire pit lights but doesn’t stay lit, this can also be a result of dirty ports or faulty valves.

Step-by-Step Procedure To Replace A Gas Fireplace Thermocouple

1. Step 1: Use a wrench tool to unscrew the connector.
2. Step 2: Unhook the probe from its clip.
3. Step 3: Take the removed thermocouple to the hardware store.
4. Step 4: Replace the new thermocouple with the help of a probe.
