Onlyfire Stainless Steel Fireplace H-Burner for Natural Gas & Propane Fire Pit and Fireplace, 12 x 6 Inch Rectangular DIY Firepit H Burner for Indoor and Outdoor, BTU Max 60,000

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.

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.

Works great, put it in my outdoor firepit.

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.

very good product

Built my own gas fire pit for a fraction of the cost. Very nice quality burner. Flame shown is at half flow, gets pretty big at full.

Website didn’t explain that it needs a pan and they won’t accept returns.

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!
