New here and I have been looking through the past threads for several questions about the King 5510. Great info on this site!! Sorry if I missed an answer to my questions but I am conserned with draft fan. I just purchased this stove at Tractor Supply on sale and I have never been around a pellet stove. Needed a sorce of heat in my shop. It seems nice start up etc. went ok. Upon restarting the draft fan will run steady but when the stove heats up the fan goes into a on and off mode. Is this normal operation? During this time I will get a flashing light over the Draft Fan button. What may be causing this? Any info would be apprecated, Thanks
