Feed Rate Fine Tuning
The 44 Magnum is equipted with a fine tune ad-
justment for the feed rate. This adjustment changes the
output range of the stove from 44,000 btu high and 8000
btu low to 30,000 btu high and 6000 btu low.
This adjustment is set in the "High" position at the
factory to provide maximum output.
The benifit of turning the adjustment to "Low" is
that a hopper full of coal can last up to a week while a
very low stove temperature is maintained.
Turning the adjuster clockwise increases the feed
rate while turning it counterclockwise decreases it. Al-
ways stop with the adjuster handle pointing down.

Low Combustion Air Fine Tune Adjustment
This adjustment should only be made by an autho-
rized Harman dealer using a draft meter to check re-
sults. The Low Combustion Air Adjustment is set at the
factory in the minimum position. This setting should give
the proper combustion air with 118 V.A.C. 60 Hz or
higher. This adjustment is only used if the voltage sup-
plied to the stove is too low.
