Hi there... Sure, let's compare notes to see if we can identify an explanation for your observations on your Harmon XXV.
I suspect only two issues that could (temporarally) be resolved by a vacuum-only cleaning of the pellet stove as you have experienced. Specifically, clogged air holes in the burn-pot or combustion-air blower congestion.
While scraping the heat exchanger once a week is likely good practice and apt to keep operating efficiency high, it is not likely that a vacuum cleaning would significantly change the amount of deposits, and is not likely your issue.
It is also not likely that a clogged flue would be resolved by a vacuum cleaning. I brush-out my flue after each ton of pellets, but not likely your issue.
The stove is intellegent enough to vary its heat output based on how much it has to heat a room compared to the thermostat setting. Could be simply that some days it does not need to warm the room as much as other days. But you likely thought of that and are comparing similar flame sizes giving different heat outputs.
A vacuum could open partially clogged burn-pot air holes for a short time.
This seems to be a good possibility to explain your situation. Perhaps combustion does not start deep inside your burn pot, leaving very little room & time to burn fuel completely before it reaches the edge of the pot. Clean the burn pot holes all the way to the bottom of the pot - taking care not to poke at the fragile heating element directly under the holes. As mentioned - remove the cover under the burn pot and clean out ashes in that area. Procedure is described in the manual.
A vacuum could also partly open/clean the combuston air exhaust path and blower. that would be my second place to look and clean. Check the manual for that procedure.
Best of luck. Let us know how it goes!!
