I was told by the CDL sales rep. that the new Intens-O-Fire draws the combustion air through the inner and outer side walls to pre-heat the air. by doing so he said it increases the efficiancy by something like 5%.

I guess I should restate what I meant is that the air should be coming from outside as there is more oxygen in that air but it is warmed up by the arch itself, There has been some so called improvements in the design of the arch since it has left my hands, but the only thing that I see that has changed is it dressed up a little with a total stainless outside and the damper controls have changed, the inside is basically the same.
