I installed a Lochinvar Noble Combi 199. The air intact on the side of the house sounds like a leaf blower running non-stop and approaches 70dB. My 3 inch intake pipe run is approximately 10 feet. The specifications allow up to 100 feet of pipe. Is there anyway to reduce the speed of the fan in order to reduce the noise level? I've already installed the Lochinvhar pipe silencer... which reduces high frequency noise but not low frequency noise. The fan also runs non-stop even when there is no call for hot water. Is there any way to get the fan to turn off when in standby mode?
