Just had an Harman Accentra free standing stove installed yesterday and they did not explain it very well and my sales person is on vacation now. What is the best setting to run the stove on, room temp or stove temp? I will be trying to heat the first floor about 1200 sq ft. The manual says set the feed rate at 4 the installer said 2.5. Also the room sensor included is only 5 feet long they say you can extend that to a 100' maximum, but reccomend only 25 feet max? What gives with this? I think I will run stove on stove temp mode trying to heat all first floor which will need the stove to run most of the time. Any other thoughts you could give in the operation of this stove would be helpful. This is my first pellet stove. Thanks for everyones help.
