Gerry Parent wrote:Peter, I think I remember reading something about you saying something over at Proboards.com (which I can't find right now) that flames that come out of the riser are not the most ideal situation. If this was you that said this and is a correct statement, could you elaborate on it a bit and what could be done to make it more 'ideal'.

Gerry Parent wrote:1) Do you load your entire batch of wood in (to within about 2" to the ceiling) then reach way to the back to light it with a long match? What I found is that its takes a while before the fire catches the wood below it when lit from the top vs starting it at the base of the stub.

Rune Dahlgreen wrote:Now regarding the newest version (since Peter mentions that the the feed/horisontal part is now larger and "The feed is close to twice as large as the stub, csa-wise") is it safe for me to conclude that the horizontal part should be close to 10 % riser CSA and the vertical part of the newest floor channel should stay in the same range, close to 5 % of the riser CSA?
Also back in the days of the P-channel coming down from the 'ceiling' of the fire box Peter emphasized that the width of the P-channel should be as wide or slightly wider than the width of the port. Can we now totally disregard this rule for both the horisontal and vertical part of the newer floor channel?
