I recently noticed a flame coming from behind the flame guide and leaving deposits of creosote on the bottom of the fire brick. I have verified there is no creosote built up on the back plate of the burn pot assembly. The four ½" nuts which secure the assembly are tight & I replaced the flame guide [in case of a warpage] and am getting the same result.

The Flame is coming from between the flame guide and back plate where the two butt together.

I have two p68Âs and have not had this issue with the other stove.

When the stove is running on high, this is not an issue; only when idling in manual mode with a small flame do I noticed this new behavior. I have seen this before, but not to this extent. ~ The flame leakage seems excessive compared to normal.

I noticed this immediately after a thorough cleaning as per the manual instructions. BTW, IÂve had unit 1 for 5 years, and know the procedure very well.

I have burned Valfei 100% hard wood pellets for the last three years and the seem to be great quality.

Any ideas or advice would be greatly appreciated
