A note about fuel: Use only dried shelled corn with a moisture content of 14%

t t t e
t
(11 to 12% provides the best results); any pellet fuel used should
have an ash content of 1% or less. If not, effi ciency will suffer. This heater has
n
successfully burned pellets with a 2-1/2% ash content, though less ash is preferred
s
lly burned pellets with a 2-1/

y burned pellet
and more effi cient.
