Hello Harman Acentra 2 FS. Is this normal with No OAK. The venting goes up 3 feet and out thru the thimble. The stove is approx 5 years old. There is no OAK, but a round hole in the sheet metal for it. The hole is blocked with OEM insulation on the inside. Half was opened up on the left side. Should this insulation cover the OAK hole? The ignitor is closer to the left side of the burn pot? Is the ignitor weak? I did cleanout under the burn pot just before lighting. See pis below. What is your experience?
