A very warm welcome to the forum from the South Coast of New South Wales Austrlia.
The solid fuel tablets have a stink that I don't personally find tolerable, if windows are open and there is fresh air I would say that its 'amply' safe to burn them, but you will find the stink obnoxious.
In regards to the D6, its as Bruce mentioned above.
I would suggest for the time being just steaming up that D6 as often as you can and really enjoying it and getting to know it. Put some hours into steaming her up.
Take pics and videos.....we love pics and videos!
Enjoy the forum.
