Harmonic Noise
On occasion, a whistling noise may come from the RHFE-1004FA using propane gas. This harmonic noise can
be attributed to varying gas compositions and is more prevalent on new tank sets that may still have high traces of
methanol in the system. The adjustments recommended are not detrimental to the operation of the appliance in
any way.
PROCEDURE:
1. Perform the Gas Pressure Setting Procedure. During this procedure, set the low fire manifold gas pressure to
3.9" W.C. and the high fire manifold gas pressure to 9.8" W.C.
2. After performing the above procedure, set the low fire burner air shutter to three notches. This adjustment rod
can be found on the right hand front burner just under the gas line where it enters the combustion chamber.
Loosen the set screw in the brass slide and slide the shutter rod out to the third notch.
