The difference between LP and NG burners that we carry 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. Propane – prosFlexibility/portabilityOpens up new location possibilitiesSometimes NG is not availablePropane – consMore expensive to burn than NGHeavier than air, so it sinks down. This makes ventilation more important.Requires refilling the tankHiding the propane tank can present new aesthetic challengesBlack soot tends to build up faster on fire media such as ceramic logs and cannonballs (it can be cleaned off)Natural Gas – ProsCheaper to burn; you probably won’t even notice an increase in your gas billYou won’t run out, so burn to your heart’s content without the dreaded “we’re out of gas”Since it’s lighter than air and rises, there’s less likelihood of unwanted fuel accumulation in the vesselSlightly cleaner burning; less soot build upNatural Gas – ConsLimited to what’s available in your areaMay require upgraded meter or larger diameter fuel lines to provide adequate BTUsThe volume and pressure can be affected by other appliancesMight require a longer gas line, depending on where your fire feature will live Would be difficult to change the fire feature’s location after installationCheck the side of your gas meter for a BTU rating. Most commonly they are rated at 250K BTUs Gas Line Sizing 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.Propane Gas Line Sizing ChartNatural Gas Line Sizing ChartGas line sizing variablesUsing angled couplings can reduce the volume/flow of fuelAdding a 90 degree angle in your line adds the equivalent of 5 feet of distanceRunning different sized lines over various distances is acceptable, but for maximum fuel volume, run larger lines over long distancesNumber of appliances, whether it’s a dedicated line or not; all these factors play a role in volume and pressurePro Tip: if you haven’t installed your gas line yet, consider running it in conduit so that if you ever need to repair or change it, you won’t have to dig it upYou 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. Gas Pressure Now that you understand the importance of volume (BTUs), let’s talk pressure. Optimal Pressure:LP: 11-13″ water column (w.c.)NG: 7-10″ water column (w.c.)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 ManometerPressure too High? You may experience unwanted noisePressure too Low? The flame will not be as tall and hot Gas Stub Location Location of Gas StubCan be off-center or on-center, depending on the size of your fire featureThe key valve is generally located on the side of the fire pit, so if it makes sense for your build, place the gas stub off-center to reduce the distance of gas stub to key valveInstruct the contractor to keep the gas stub as low as possible to make room for electronic ignition, or in the case that the plate sets fairly lowOn some builds, the plate sits only 8″ off the ground Regulators & Air Mixers You DO NOT need an air mixer with any of our burners. Air is mixed at each jet. LP RegulatorsFor optimal regulation for burners over 200K BTUs, contact a local propane supplierFor regulators 200K BTUs or lower, CLICK HEREFrom the tank, propane is HIGH PRESSURE, so it must be regulated down, because the burners are low pressureFor longer gas lines, we often use a high pressure (10psi) regulator at the tank end, and a “2nd stage” regulator on the other end of the line to bring the pressure to 11-13″wcNG RegulatorsConsult a professional (plumber/HVAC) Using a Propane Tank Standard 20lb TankA standard 20lb/5 gallon BBQ propane tank can be used for burner systems 180K BTUs and underThe FIRE CUBE is a complete unit that can have a self-contained propane tankBurn time varies from 6-12 hours, depending on how hot you run itResults may vary, and it is common for the fuel to “freeze up” with burners 180K BTUs and up. What that means is that after 45 minutes or so, the flame only goes to about half. Remedy this by using two tanks connected together40lb TankThis is a better option for most of our burners from 100K to 200k BTUsIt will give you longer burn timesStill relatively small and easy to moveHigh Volume TanksContact your local propane supplierHiding the TankYou can always run a larger diameter line and hide the tank in an inconspicuous locationYou can purchase 20lb propane tank covers that make hiding the tank a cinchGas ConsumptionAll of our burners burn with incredible efficiency due to the engineered jets. They mix fuel and oxygen at the flame which makes it taller, brighter, and hotter using less fuelRead all about how much fuel you might be burning at full capacity – Learn More Fuel Cost Calculator Calculate HERE*Note: our burners will burn with more efficiency than others because of the proprietary jets Permits & Certifications Compliance with the following standards:ANSI Z21.97/CSA 2.41 Outdoor Decorative Gas AppliancesThe burner system is certified nationally, however, it is up to the customer or contractor to verify local requirementsCertified BurnersMassachusettsEffective May 5, 2021 over 100 Warming Trends CROSSFIRE burners will be approved for use in Massachusetts.

Canadian CustomersMost metropolitan areas in Canada will require an automatic shutoff for fire pits over 65K BTUs in order to get a permit or certification.Our Premium Electronic Ignition system has the proper fuel and flame censors to automatically shut down the fire when needed. Combine it with a dial timer to increase safety and ease. You can still purchase higher BTU burners without the premium ignition, and we will ship it with a fitting that limits the burner to 65K BTUs in the case that you’d like to have it certified.

Nice try!)Other burners are made by poking small holes in stainless steel tubes. Gas just seeps out without mixing oxygen. The flame is small and not as hot or controlled, hence the smaller BTU ratingsGoing with a stainless steel burner greatly increases the risk of being bummed with your fire Crossfire burners produce twice the amount of flame with the same amount of fuel as conventional stainless steel burners Brass vs. Stainless Steel Almost everyday we get inquiries like this: “I have a fire pit with a stainless steel burner but I’m not happy with the flame. It’s only 5″ high and it doesn’t put out any heat. What can I do?”This is the reason why we ONLY carry Warming Trends Crossfire brass burners; because we don’t want to have that difficult conversation with our customers. If you have an adequate fuel supply, you WILL be satisfied with our burners!You may pay more upfront for all brass, but you will pay less over time for these reasons:Brass does not corrode over time like stainless steelYou won’t feel the need to “upgrade” to get a better flame… you will already have THE BESTLimited LIFETIME warranty!
