Concrete/GFRC fire features WILL develop charring and non-structural cracking, aka hairline cracks. This is the nature of concrete and thus, not covered by warranty.
For the ultimate durability, consider a steel, aluminum, or ready to finish fire pit.
Nearly ALL concrete fire pits, whether sold by Montana Fire Pits or others, will eventually develop the same characteristics of browning/charring AND hairline cracks. The cracks can appear anywhere on the concrete shell, but are most prominent on the inside ledges nearest the fire. Visibility of the hairline cracks has been known to diminish when the unit is dry. The cracks will re-appear when any moisture is present. These characteristics can develop as soon as 20 minutes after lighting the fire.
Exceptions:
Shipping damage that has been properly photographed and documented by the receiver, as well as submitted to Montana Fire Pits within 3 days of delivery, OR ideally the shipment is refused, will be considered for a freight claim based on evidence provided by you, the customer or receiver.
If you wish to proceed with a concrete fire system, we’ll send you a document to sign which is your acknowledgement that the warranty does not cover cracking, charring, or chipping.

There are various pros/cons of Liquid Propane (LP) and Natural Gas (NG). The difference between LP and NG Warming Trends burners are the “jets”. If, down the road, you need to convert from LP to NG or vice-versa, you can do so by purchasing replacement jets from us at $25 each.

Even though the standard key valve inlet is 3/4″, you may need a larger gas line to span long distances.
In order to get the proper volume and pressure of fuel, you need a gas line that is large enough in diameter to carry it sufficiently. For the most accurate assessment, consult a fuel professional. For a rough estimate, utilize our gas line sizing charts below.
*Make sure the BTUs from your line can supply at least 60-70% of what the burner is rated at. (At 60% capacity, your flame height may be more like 18″ high vs. 24″+ at full capacity.)
Gas line sizing variables
You can have great gas pressure, but if your line is too small, you may not get the desired flame. Think about it like filling up a swimming pool. If you reduce the nozzle size significantly, you may have a ton of pressure, but it’s going to take longer to fill up the pool. You need both pressure and volume to get a great flame. This is why the size of the gas line is so important.
Now that you understand the importance of volume (BTUs), let’s talk pressure.
Optimal Pressure for Crossfire burners:
Water Column is the term used to measure pressure. There are 27.7 inches of water column pressure in 1 PSI of pressure. So 7″wc is about 1/4 PSI. This is the normal pressure that household natural gas is delivered.
The device used to measure pressure of this type is called a Manometer
Pressure too High? You may experience unwanted noise, usually a hissing sound. You might also find it difficult to dial in the desired flame height using the key valve.
Pressure too Low? The flame will not be as tall and hot
Location of Gas Stub
You DO NOT need an air mixer with any of our burners. Air is mixed at each jet.

*A burner plate or pan is required for use of any ignition system other than match lit.
The main purpose of the plate or pan is to hold in the media (lava rock, glass, etc). It also acts like the hood of a car, in that it can be lifted up and out in order to access the gas line or key valve underneath. The plate/pan makes installation easier as well.
What’s it made of?
Is a plate/pan ALWAYS necessary?
Plate (No Sidewalls)
Pans (2″ or 3″ Sidewalls. 2″ is Standard.)
Drop-In Pans (2″ or 3″ Sidewalls + 1″-2″ Lip)
Does the plate attach to the burner?
There are many methods to mount a plate/pan inside your fire feature. We’re just going to tell you our favorite way to do things because… well, it has worked well so far! With that being said, these methods may not work in all situations, so put your problem-solving hat on and get creative.
*Complete & RTF Systems: you won’t need to worry about plate/pan mounting; they’re designed for simplicity
Mounting the Plate/Pan
Plate/Pan Depth
If your fire feature is already built and you can’t use a standard sized plate, you have a few options:
Cut your plate to size on-site
Make your plate bigger
Order a Custom Size
*TIP: Give yourself about 1/2″ of space around the plate so that it’s easy to insert into the fire feature opening
(Recommended)
Enables easy flame height adjustment as well as the ability to turn the gas on or off. All flex lines are stainless steel and whistle free.

Any movement or blockage of the spark will restrict the ignition from working properly. In these cases a conventional lighter can be used to ignite your fire.
