(A) Just an observation, and likely my Harman Accentra insert has always done this — but, I notice, about 1/2 hour after light-off, the flame level drops quite a bit (but never goes out) for a bit (I do not time it, but perhaps for about 15-20 minutes), then returns to normal. I would suspect this might be because I’m running on Room Temp (yeah, I know, perhaps some day I might experiment with trying to route a line for an external thermostat) and after 1/2 hour the temp inside the unit is high enough to signal dialing back the feed significantly. True? Is this normal?
(B) Well, after various discussions here, I am convinced I need to avoid burning consistently at a low flame level, so I have increased the temp setting to just under 3-1/2. Yes, the flame is higher now. For a point of reference, I’ll refer to the East-West line on the “Medallion” ornament inside — let’s call that the Equator. Previously, the Equator was probably as high as the flame tips ever got. Now, at the higher setting, the flame tips almost always are at or above the Equator, varying up to a max of "at the top of the glass" (kinda hard to see once they get above there). So, now I wonder if I am burning sufficiently hot enough to prevent build-ups, etc. I’d think that an actual temp reading would be more definitive.
