Just rebuilt my f602 n, replaced the upper air/secondary burn chamber, trying to chase down why it's burning so hot (will post a how-to in another post, since there doesn't seem to be much info on the interwebs). Haven't fired it up yet, but if it's still hot I'm going to replace the glass gasket from 3/16" plain gasket to 1/4". Any reason not to use graphite gasket?
 
The gasket should match factory spec, particularly in density.
 
I'd like to use something a little thicker to get a better seal on the glass. The manual is rather cryptic: "Gasket................................................LD 187-1 Ø4.8x600"

Ld= low density? Can you elaborate on the significance of the density on the seal?
 
Graphite is fine, some manuf. uses them stock.
 
How bout the density? Seems that if anything a higher density would be better, as long as it fits.
No, high density can actually cause greater problems in the wrong application. Lower density compresses better and sometimes makes a better seal. Some stoves and applications are more particular than others in this regard.
