Review: Great Product, Needs whistle free flex line or standard pipe connection - 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.
Review: its working good for my fire place - very good product

very good product

### ⭐⭐⭐⭐ Works great, but whistles
*by R***S on April 22, 2021*

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.
