I just go my brand new Avalon Flush Wood Plus Insert (rectangular) installed and when burning it makes a whistling sound.The Flush Wood Plus is the medium size insert without a catalytic converter.
The unit has two controls. There is a bypass rod above the door which controls the flow of smoke inside the heater. When pulled out, smoke goes directly up the flue. When pushed in the smoke goes around the baffle, utilizing the secondary combustion and making the heater more efficient.
Then there is an air control slider to control the burn rate of the stove. Closed gives a low burn rate while open results in a high burn.
After starting the fire I pull out the bypass rod and open the air control. About 30 min later when it burns nicely I close the bypass road to take advantage of the secondary combustion and then the insert starts to whistle. Not super loud but enough to drive you crazy over time. When I open the bypass all the way it stops. If I push it in just a tiny bit it starts. The bypass can be pulled out about 3 inches and pushing it in just a quarter of an inch will start the whistling sound. The whistling does NOT change in intensity depending on how far it is pushed in. The whistling also does NOT change when the air control slider is changed.
The question is if this is normal. The installer told me that fire place inserts have wind noise and that's just the way it is. Somehow I don't buy that. Does anybody else have a FWP insert and can comment on the noise?
When the fire is off there is no noise regardless of the position of the controls.
I have an insulated stainless steel liner and about 20 feet of flue.
