Onlyfire Stainless Steel Fireplace H-Burner for Natural Gas & Propane Fire Pit and Fireplace, 36 x 6 Inch Rectangular DIY Firepit H Burner for Indoor and Outdoor, BTU Max 175,000

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.

Buy these stainless steel versions - they last longer and work great. Much, much cheaper than getting them at the local hardware specialty stores.

Works great, put it in my outdoor firepit.

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.

This was easy to install in outdoor fireplace but too loud to use while having a conversation.

Added a mixing valve and some stainless flexible pipe to this and installed in a wood burning outdoor fireplace to convert it to propane. Way cheaper than the kits to buy the individual pieces.

Works fine, but whistles. The price was great, so it's still a bargain. This doesn't come with any fittings, so make sure you have what you need to install, or buy a kit.
