Features

  • H-Shaped Flame Coverage Longer, Wider, More Even - Our H-burner distributes gas through three connected pipes creating a broad, uniform flame across the entire 36"x6" rectangle. No dead zones, no hot spots. Just a full, beautiful fire display that makes your fire pit or fireplace look professionally designed.
  • 42% Thicker 304 Stainless Steel Won't Warp or Rust - Crafted from commercial-grade 304 stainless steel with 42% thicker pipe walls than standard burners. Most thin-wall burners warp under high heat ours stays straight. Resists corrosion in coastal or humid climates. This is a burner built to outlast your fire feature.
  • Drilled Gas Ports No Whistling, No Annoying Noise - Every gas hole is precision-drilled (not punched) for smooth, silent gas flow. Cheap punched-hole burners create a loud, irritating whistle ours gives you a quiet, steady flame. Enjoy the ambiance, not the noise.
  • Hollow Pipe Design Smoother Gas Flow, No Blockages - The interior of the H-burner is fully connected and hollow gas flows freely through all three pipes with no internal obstructions. This means consistent flame height across every port, fewer blockages, and reliable performance year after year.

    • Great Product, Needs whistle free flex line or standard pipe connection
Size: 36 x 6 Inch
This is a great product at a great price and works just fine. There are a few reviews about whistling and to be honest, we had very high pitched whistling when first installed. This isn't a problem with the unit, but rather a consequence of the flex line connection my plumber used. Traditional yellow flex lines have A LOT of tight ribs with sharp edges. These lines can kink and add a lot of additional disruption to the flow of gas. As a result they create significant turbulence which vibrates and causes whistling at higher flow rates. To get rid of the whistling you need to ideally just use solid pipe and pipe bends (smooth on inside so no turbulence) or specially designed whistle free flex lines. This will clear up all problems. The use of an additional orifice isn't going to make much of a difference if you are using a yellow flex line. I would guess that the other reviews with whistling are all used flex lines. While this might work with shorter burners, the larger the burner the greater the resonance and whistling you can create. ... show more

    • H Burner - Fireplace - With Min Whistle/Hiss. Now With Log Sets Added

Used 30” H burner, a 150K air mixer, and 50 lbs. of 1.5-2” lava rock. Ended up with this great looking propane fueled fireplace. It looks very different from the standard “Gas Fireplace Logs”.. Tell guests we burn ”Coal”… because that’s exactly what it looks like. Lava rock glowing a nice amber red after a few minutes of operation. A nice blue/yellow flame shows the propane air/fuel mixture correct. Hint.. The air mixer / corrugated SS flex piping wants to introduce an annoying whistle/hiss. The trick in minimizing the sound, is the piping. Start with the flex piping from the fuel source to air mixing valve. Then from the air mixer, using ½ black pipe .. at least two 90 elbows and a total of 10”-15” + of ½ black pipe to H burner.. Piping works as a muffler for the hiss.. Don’t directly feed H burner from corrugated SS flex piping will introduce a whistle. The mixer valve noise was further reduced by sliding the air mixing valve assembly inside an 18” +/- length of open ended 1-1/4” black pipe, combined with creative use of insulation and burying the above in the back of the fireplace under a layer of lava rock. (Some engineering skills required.. But you get the idea.. ) If you have natural gas, installation becomes much simpler. No mixing valve but still use the same logic with the SS flex hose / ½ black pipe to prevent introducing a whistle/hiss. The same logic holds when assembling an outside fire pit. Enjoy. Just added two boxes of "10 Count - Large Log Sets" from Amazon .. Looks real nice... ... show more

    • onlyfire 304 Stainless Steel Fireplace and Fire Pit H-Burner, 18-Inch by 6-Inch
Size: 18 x 6 Inch
Shipping was fast. Had my propane company hook it up so I don't have no gas leaks and put in my fireplace right. I have a prefab fireplace that burns wood also. Unit throws a lot of heat and flames get pretty high. Well design unit. After it is off and gas off takes a few minutes to cool. Just use a little gas to light it. Be careful. Overall good buy. ... show more

    • It has a whistle when turned up more than low.
Size: 36 x 6 Inch
Review Image by Amazon Customer
The flame on this is awesome! We have it hooked up to a 3/4” gas line so there is plenty of gas to light the flames. Delivery was great. I only gave 4 stars because it has an annoying whistle when the gas is turned up. On low the whistle is not really noticeable but then the flames are small and not warming really at all. I read a review somewhere that they had a whistle and drilled the holes bigger and it stopped. I’m going to try to do that so hopefully it improves! ... show more

    • Looks Good
Size: 12 x 6 Inch
Installed this with a no whistle flex gas line. The local fireplace store didn't even want to sell me any of this stuff, so their price would have likely been out of line as well. Recommended if you have a smaller fireplace like me, and follow the rule of thumb to keep the flame 2 or three inches from the sides. ... show more
