Q - My pilot is very noisy and loud. How can I make it more quiet.
A - All control valves have a pilot adjustment screw. Turning it clockwise will reduce the flow of gas to the pilot. The optimum adjustment is just before the point it makes noise. If adjusted too low, you will experience nuisance pilot outage.
Another cause of excessive pilot noise is that the inlet pressure of the gas supply is too high. If you are using natural gas, it should be 7" water column (1/2 psi); 11" for propane. This is a job for your gas supplier or gas fitter.
