1.­ First­Locate­the­hardware­package.­You­will­find­four­long­
screws­for­the­base­tubing,­along­with­4­nuts­and­washers.­
Place­the­heater­on­the­base­tubing­as­shown­on­the­front­of­
this­manual­or­in­the­parts­diagram.­Use­the­long­screws­and­
matching­fasteners­to­attach­the­base­to­the­fuel­tank.
2.­ In­the­hardware­package­you­will­also­find­two­shorter­
washer­headed­screws­for­attaching­the­handle­to­the­top­of­
the­heater.­Using­a­Phillips­headed­screw­driver,­attach­the­
handle­to­the­top­of­the­heater­as­shown­on­the­front­of­this­
manual­or­in­the­parts­diagram.­­
3.­ Finally­install­the­lower­heat­shield.­The­included­heat­shield­
will­be­located­centered­at­the­6­o'clock­position.­Only­two­
screws­are­used­to­hold­the­shield­in­place.­The­middle­hole­
is­only­for­the­locating­pin­that­receives­no­fastener.­Simply­
remove­the­screws­that­line­up­with­the­holes­on­the­heat­
shield­when­on­the­centering­pin.­Put­the­heat­shield­into­
place­and­re-attach­the­screws.­
PREPARING FOR OPERATION
1.­ Check­the­heater­for­possible­shipping­damage.­If­any­is­
found,­immediately­contact­the­manufacturer­at­
800-251-0001.
2.­ Follow­all­of­the­"Precautions".­
3.­ Fill­the­fuel­tank­with­clean­kerosene.­In­extremely­cold­
weather,­condensation­may­develop­in­the­tank­and­it­is­
recommended­that­a­tablespoon­of­de-icer­be­added­for­
each­gallon­(4­liters)­of­fuel­in­the­tank.­When­filling­the­
heater,­use­at­least­2­gallons­(8­liters)­of­fuel.­Be­sure­heater­
is­level­and­do­not­overfill.­Use­a­funnel­or­can­with­a­long­
fill­spout.
IMPORTANT: Before filling fuel tank the first time or after
extended storage periods, drain the fuel tank of any
moisture or condensation.
4.­ Locate­heater­at­a­safe­distance­from­combustible­materials.­
Refer­to­the­specifications­table­in­this­manual­for­distances.­
HEATER START UP
1.­ Locate­the­power­plug­near­the­controls­of­the­heater.­Using­
a­properly­sized­and­grounded­extension­cord­plug­in­the­
unit.
2.­ When­power­reaches­the­heater­the­Red­light­on­the­back­of­
the­heater­will­illuminate.­
3.­ Turn­the­power­switch­to­the­ON­position.­The­LED­read­out­
will­show­the­approximate­room­temperature.­When­you­turn­
the­thermostat­knob­clockwise­the­LED­readout­will­change­
to­show­the­set­temperature.­When­that­number­is­higher­
than­the­room­temperature­the­heater­will­begin­is­sequence­
of­operation.­
4.­ Once­the­heater­begins­to­run­it­will­cycle­on­and­off­based­
on­the­thermostat­setting.­If­for­any­reason­your­heater­does­
not­run­properly­refer­to­the­Diagnostic­and­trouble­shooting­
section­in­this­manual­or­contact­the­manufacturer­with­one­
of­the­methods­listed­on­the­back­page­of­this­manual.­
HEATER SHUT DOWN
1.­ To­turn­off­either­turn­the­thermostat­knob­to­a­temperature­

operation).
2.­ FILTERS.­Dirty­fuel­filters­will­cause­an­imbalance­in­the­air-
fuel­mixture.­The­best­indication­that­this­condition­exists­
is­an­increase­in­odors­or­difficulty­getting­your­heater­to­
