I have attached a link to the Harman owner's manual for the TLC2000http://www.harmanstoves.com/doc/tlc2000m.pdf
This link is broken, either the page no longer exists or there is some other issue like a typo.
As far as your questions:
Mantis wrote:My question is, can you remove the three bars in the front of the fire box for an unobstructed view of the fire?
Yes. The bars themselves simply slide out & the bracket that holds them also comes out. No toolzs needed.
Mantis wrote:For those that say they use the front door to load the stove; how are you not getting a blast of smoke.
I open the bottom (ash) door first & let the fire liven & the draft improve. (just a few minutes is usually all it takes) Then, I open the glass door (or top load door)for loading. (the chimney draw will keep gases being sucked in) The Harman manual warns against opening the ash door & the glass door simultaneously, but I do it all the time....once the draft is livened up
Mantis wrote:Devil, you mentioned adding more brick to allow for more coal. How do you avoid flashover when adding so much more coal on the fire? I’ve read about people leaving an open flame somewhere in the box but is that possible to do with the added amount you’re loading in or do you just fill it without a problem?
Not sure what you mean by "Flashover" but coal fires are not like wood fires in that the amount of coal you add has little to do with the size/heat of the fire. This is done by controlling the amount of air provided to the fire. 2nd, adding another layer of firebrick does not allow for that much more coal to be loaded in the stove due to the static height of the window bars which merely allow you to slope more coal towards the back, & thus give you a bit more coal for a longer fire. The main
benefit of adding firebrick is to make loading easier,( especially if top loading) by preventing loose coal from landing on top of the original firebrick.
In re this question:...."I’ve read about people leaving an open flame somewhere in the box but is that possible to do with the added amount you’re loading in or do you just fill it without a problem?".....
You can always leave a section of the coal bed uncovered & flaming when you reload. (practice by doing 1/2 of the fire bed at a time) Then go back in a few minutes (when the freshly covered section is now flaming) & add coal to the untouched area.
In re burning wood fires, especially early & late in the heating season, I rarely do it, but I do occasionally. My simple reason is the lack of wood to burn & the much greater ease of burning coal. Wood stinks up the house, while coal adds no aroma to the air & coal fires are so mush easier to control & keep burning that you will tend to become lazy & prefer to just stick with coal!
I suggest you read the owner's manual to see if your questions are better answered.
