FAQs

Crystal Fire® Burners

Are there different Crystal Fire® Burner models?

We have many different Crystal Fire® Burners and over 50 fire pit tables in stock. Many of these can be purchased as one complete unit or individual components. Custom fire pit tables & burners are also available. 

Are these burners UL listed? What does that mean?

Yes, all of our burners are UL tested and listed. This means they have passed numerous tests to ensure safe operation. They have undergone wind, rain, and clearance tests.

Can I burn wood in my gas fire pit table or fireplace?

No, these units on not wood-burning. The benefits of a gas fire appliance include a smoke free experience, turn on instantly, and provide instant heat.

Can I roast marshmallows over my Crystal Fire® Burner or Fire Pit Table?

Yes you can, however this appliance is UL listed as a decorative gas appliance, not a cooking appliance. Any residue from the food should be cleaned off the gems/burner, as it will clog the burner ports and prevent a proper burn.

Can they operate on propane or natural gas?

Yes, they can be operated on either full source. The majority of our fire tables come all set up for use with propane and do include a natural gas orifice that can be converted in the field. If converting to NG, a certified gas technician should do the installation. Some of our larger BTU burners and custom burners need to be specified for either LP or NG use. Please contact OGC for specific skus.

Does my Crystal Fire® Burner or fire pit table require adjustments for higher altitude operation?

The Crystal Fire® Burner Design does not require High Altitude Adjustments. Complete explanation below: In the standards today there are requirements for de rating the input of a gas appliance in high altitude applications. The reason for this is gas appliance performance is affected by the available amount of oxygen in each cubic foot of air as you increase elevation. The requirement in the US for a 4% de rate for every increase of 1000’ of elevation has been around some time. But there are a number of things that make the calculations and need for this more complicated than just changing the orifice to reduce flow by 4%/1000’. Things like the gas being de rated by the gas company (by adding nitrogen to the mix to reduce the actual BTU content), pressures altering the amount of flow through an orifice, the type of appliance being power vented or open atmosphere. The actual tested input rate performed by the lab. In Canada you are allowed to increase your input for combustion to simulate high altitude installations. Regulations have some appliances exempted from the reduction in rate such as outdoor BBQ grills. Some manufactures de-rate their appliances at the factory to allow for a not having to de rate in the field.

The technical reason for the de rate is the reduced amount of oxygen can cause more CO creation during combustion than during normal elevation operation. This is caused by restricted amounts of air being supplied to the combustion area for primary and secondary air. Other issues causing a higher CO production can be the design of the burner, combustion chamber and the heat exchanger. The manufacturer is designing to meet government requirement for efficiency, safety standard requirements along with the need to be price competitive. So a product can become complex trying to accommodate every situation without requiring some modifications for the environment it is installed in.

When it comes to outdoor- free air- no combustion chamber- appliances, the need for de rate becomes less important. There is plenty of air for combustion, the combustion chamber is limitless so no impingement from slower burning taller flames, no heat exchanger or vent to restrict air from entering or exhaust from escaping. And all the outdoors for dilution of combustion products to prevent the possibility of high CO or exhaust concentrations anywhere. If you compare to a wood burning fire pit that may be burning closer to 2 million BTUs/hr. and a natural gas or LP gas burning appliance at 100,000btu/hr. There is virtually no exhaust to contend with or CO of any comparison to wood.

It is of course important to start with a listed product, these are tested to ensure proper lighting, combustion, and construction. Where a non-listed burner will not provide a known starting point for these safety areas.

At OGC we start with a listed burner and increase input well beyond the rated input of the burner to ensure that our burners are not going to require a de rate in the field for altitude. But we are not the final authority when it comes to installation in the field. You must follow all the requirements of your local jurisdiction when installing any gas appliance in the field. If the local authority requires de rate we can help you meet those requirements.

How long will a 20 lb. LP tank last?

Typically you can operate for an average of 8 hours when burning on high and up to 20 hours when burned on low.

How many BTU's per hour are produced?

The BTU rating for each burner varies by size and fuel type. For the exact BTU rating consult your Crystal Fire® Burner Manual.

If I purchase a Crystal Fire® Burner for my own project, what else do I need?

It will depend on your project. More than likely, you will need to purchase a control panel, key valve, timer, or Direct Spark Ignition system; this will allow for easier access to operate your burner from the outside. You may also need to specify the fuel source (LP or NG) used if it is a large or custom burner. We recommend working with your local OGC dealer to determine what is needed for your project. Contact us for specific details.

Is a propane tank included?

Propane tanks are not included with any purchase. A 20 lb. LP tank can be purchased typically from hardware stores and gas stations.

Is media included with the Crystal Fire® Burner or Fire Pit Table?

Yes, we include Clear Tempered Fire Glass Gems with each Crystal Fire® Burner (some exceptions apply.) The glass used is a heat-tempered, tumbled glass gem.

Is the fire pit or fireplace approved for use in screened porches, gazebos, and lanais?

The unit itself is not UL approved for this application, but there should not be any problem provided the following guidelines are followed:

  • minimum porch area: 96 sq. ft.
  • minimum ceiling height: 92 in.
  • minimum of two walls must be screened
  • minimum of screen height side walls: 6 ft. 8 in.
  • Minimum screen area: 64 sq. ft.

What does the UL testing require? Pt. 1 Rain Test
What happens when it rains?

If the fire pit table is uncovered, water will drain through the gas port holes in the burner, into the burner neck below, and out of the air shutter. Water will not build up in the burner, it will drain out the bottom.

What type of fuels can I use?

You can choose from either LP (liquid propane) or NG (natural gas.) The Crystal Fire® Burner unit comes set-up for LP, unless otherwise noted, and can be converted to NG with a NG conversion kit that comes with the unit.

When I push in the black sparker I don’t hear any sound?

Be sure to put in a AAA battery, + side facing out into the black sparker box. The push button can be unscrewed and the battery slid in. Connect the two wires running from the burner and you should hear the sparker and see a blue spark at the electrode. For more troubleshooting tips open the guide below.
