Tips for checking and addressing problem of whistling
➤ Flex Line Problems:
1) Used a whistle-free line with varying ridge sizes, which helps to eliminate noise.
2) Chosen a line with a wider diameter to minimize whistling by allowing the right amount of gas to flow to the burner at a lower rate of speed.
3) Taken care to avoid sharp 90-degree turns and/or kinks in the line during installation.
➤ Gas Pressure is Too High
~ When a high level of pressure is applied to a small opening, the result is a whistling sound. This is the mechanism at play when the line pressure in your fire pit gas installation is too high.
~ Since natural gas is typically transported at high pressures, a regulator is often required to mitigate this pressure before the gas reaches the burner (Keep in mind that this work should only be performed by a gas installation professional, since they have the know-how to size and install the proper regulator for your fire pit configuration). Pressure guidelines are as follows:
. Natural gas: Between 3.5” WC and 7” WC.
Propane: 7” WC and 11” WC
