while checking for air leaks using an incense stick I found what appeared to be 2 factory designed holes in the bottom of my VC encore 2550 near the ashpan. I had been getting high temps (600-650) with the air completely closed lately and suspected a leak. I plugged the holes with a small piece of gasket rope and the stove has been running better (not as hot with the air completely shut down). Can anyone advise if this is dangerous in any way? IMHO i essentially fixed what would compare to a leak in the ashpan or door gasket. I would appreciate any thoughts or opinions. Thanks in advance.
