Still trying to make a desision on witch boiler to install and was wondering does a garn have secondary air at the end of the secondary chamber like other gassifier's? If so does it need to be adjusted for optimum burn like the others? Thanks Nate
Yes to the first question - there is secondary air supply for combustion in the secondary reaction chamber. Rick is correct as to your second question. No, no adjustment is possible or necessary. There are only three moving parts to the GARN itself; the draft induction fan, the loading door latch, and the loading door hinge. It could not be simpler.
