The Super Magnum is designed for use with Anthracite
"Rice"coalOnly.Anthraciteisahardcoalwhichismined
mostly in the Eastern United States. The post-mining
processinvolvesbreakingthelargelumpsofanthraciteinto
smaller,usablesizedpieces.Inthebreakingprocess,the
coal is sifted and sorted by different sized screens. Rice
size is basically dened as the coal that has a maximum
sizeof3/8"andaminimumsizeof3/16".
Mostcoalsupplierswashthecoaland/orwetitfordelivery,
to keep the dust minimized. However, the coal must be
dry when loading it in the stove. Therefore, it is highly
recommended that you purchase your coal well ahead of
theheatingseason,toallowittimetodry.Coal,whetherin
bagsorinbulk,shouldbestoredinadryarea.

TheSuperMagnum'sESPcontrol will maintain an output
level to t your temperature demands. There are two
modesofoperation;"StoveTemp"mode,wherethecontrol
willmaintainaspeciedconstanttemperature,regardless
of the surrounding environment temperature conditions,

byboth,exhausttemperature-beingreported bytheESP
(Exhaust Sensing Probe), and the microprocessor circuit
board.
We'lldiscussthesecontroldevicesandtheirfunctionsnow.
1. ESP (Exhaust Sensing Probe)
TheESPisatinythermistorlocatedintheexhauststream.
Theprobechangesit'sthermalresistancebasedonminute
changesintemperature,whichismonitoredbythecircuit
boardandusedtodeterminetheneedforchangesinthe
burnratetomeetthetemperaturedemand.
