Outdoor Fireplaces

Are additional sizes available for Ready-To-Finish Fireplaces?

We offer the ability to make custom fireplaces to your specifications. In fact, about half the fireplaces we produce are custom in size. It is most cost-economical to keep the firebox and burner dimensions standard and just change the structure dimensions. If you desire a different size firebox, we likely have the ability to provide you with a solution. Contact OGC Customer Service with a request for quote.

Are Ready-To-Finish Fireplaces UL tested for safety?

All of our Crystal Fire® Plus burners carry the UL testing. Since the fireplace structure is 100% non-combustible, there is no need to test the structure. All clearances to combustibles are taken from the actual burner manual.

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

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

Can I run a Ready-To-Finish Fireplace on my LP tank?

A 20 lb liquid propane tank should only be used for the 40” model. Longer models will burn through gas too frequently. 

Can I set a Ready-To-Finish Fireplace on a wood or Trex style deck?

Yes, provided the decking structure can support the weight of the fireplace and desired finishing materials. Clearance to combustible side rails need to be maintained from the actual burner.

Do I need to have electricity run to operate a Ready-To-Finish Fireplace?

It is highly recommended to run electricity to this structure for best performance and ease of use. In the absence of electricity, the system can run off of a battery pack (CF-DSI-BP) that uses 2 D cell batteries. If using the battery pack, it is recommended to keep the access door functional so you can easily replace batteries as needed.

Do Ready-To-Finish Fireplaces emit heat?

RTF fireplaces use the same burners used in outdoor fire pits. Heat performance from the fireplace should be greater as the heat is hitting the ceiling of the fireplace and pushing outwards.

How close can I finish to the edges of the viewing area of a Ready-To-Finish Fireplace?

You can finish right up to the edge of the opening with any noncombustible material such as stone or brick.

How do you finish Ready-To-Finish Fireplaces?

These fireplace structures are made of steel studs and wrapped in non-combustible Hardiebacker® fiber cement board. Apply desired finish directly over the cement board. Entire finish should be completely non-combustible. Clearances to combustibles are derived from the specifications of the actual burner. See burner manual for details.

How long will a 20 lb. LP tank last?

There are two factors that ultimately dictate how long your LP tank will last.

The first factor is the ambient conditions when you are operating your burner. The humidity and temperature will have an influence on how long the LP tank will last. As the ambient temperature drops, it becomes more difficult for the LP tank to keep up with the demand for fuel going to the burner. This is because the process that converts liquid propane to usable propane vapor slows down as temperature decreases. Similarly, as ambient humidity drops that same process slows down because the tank is less able to insulate itself with condensation as it converts liquid propane to propane vapor.

Flame height setting is the other factor that affects how long an LP tank will last. When the control valve is set to “High” the burner will use more fuel than when the same burner is set to operate on “Low”. See chart that outlines the estimated burn time of a 20 lb. tank when considering flame setting.

If I want a larger structure for a Ready-To-Finish Fireplace, can I build around it?

Yes. Use noncombustible framing, sheathing, and finishing materials. Venting the structure for airflow is still required. You can use the vents on the existing structure to apply to new, larger structure.

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 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:

  • A minimum of three walls are screened. Screens must be permanently open. They cannot have windows that can close.
  • The screened walls must provide a minimum open area of 30%.
  •  All appliance ceiling and wall clearances must be met.
  • Minimum porch area 96 square feet.
What are the vents on the side of a Ready-To-Finish Fireplace for?

These vents are required by code to meet the ANSI Z21.97 standards for outdoor decorative gas appliances. It is important to not obstruct these openings when finishing your RTF fireplace. These outlets allow gas to escape in the event of a gas leak, and also allow air to flow through the structure to keep it dry.

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.

Where does the gas line and electrical need to be ran for a Ready-To-Finish Fireplace?

The valve and electrical box are mounted near the left side of this structure near the access door. For ease of installation, set your utilities just inside the access door.

Who can help finish a Ready-To-Finish Fireplace?

The OGC has a network of dealers and contractors that may be able to assist with the installation and finishing of the product. Brick, stone or finished Hardiebacker® fiber cement board siding or any non-combustible material can be used. Contact OGC to get in touch with a local contractor.

Why are OGC outdoor fireplaces the best?

Traditional fireplace manufactures hard tool to build just a couple fireplaces in the most common sizes. They first build the firebox and then determine how to get a burner into it. OGC does the reverse. We take our already robust, high BTU, tall-flame burners and build a noncombustible fireplace structure around it. As a result, our fireplaces have taller viewing areas, more flame, more heat, many more sizes, and the ability to customize to the consumers desires.
