In some instances there can be noise generated by gas flow and burners while in use. There will always be some amount of noise from the gas manifold system. The objective is to reduce it to as low a level as can be while still providing a reliable, safe, easy to operate appliance.
There are a number of things that can cause excess noise while a unit is burning. Principally noise is caused by the flowing of gas through the system or the burning of the fuel. This can happen in any gas appliance, propane or natural, fire pits, fireplaces, water heaters, or furnaces. Basically the flow of gas is traveling through a line under pressure. The greater the flow (velocity) through a system the more likely there is an opportunity for noise. The products BDM supplies are a relatively high BTU product. The higher BTU means greater volume of gas thus higher velocity of flow.
The higher velocity means more turbulence in the flow and the more likely to cause a whistling sound or a rushing sound through the gas manifold system. Natural gas has a much higher potential for whistling due to having to push 2.5 times as much gas through the line to get the same BTU rate.
This all being said, potential solutions are listed below.
1. Noisy flex line
In the making of the stainless steel flex lines, the internal formations can have a flow that causes a whistling or a rushing sound. This can be remedied by reshaping the line to eliminate the noise. Bending the flex to a straighter line and eliminating sharp twists from the burner to the gas valve. If this does not work, then replacing it with a new flex line may be the solution. We have a varied corrugation flex line that helps eliminate the potential for noise in the flex line.
2. Noisy orifice
The orifice controls the amount of gas flow and is the smallest restriction point. At some flow rates the orifice can act as a whistle. To test for this simply remove the orifice and blow through it. If there is a whistling noise, you can remedy this by simply counter sinking the internal and external edges of the orifice with a .25mm drill bit, spun by hand, which should remove any edge burrs that may be causing the whistling. After countering the edges (do not drill through) test the orifice again by blowing through it.
