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 ex-
tended storage periods, drain the fuel tank of any moisture
or condensation.
4.­ Locate­heater­at­a­safe­distance­from­combustible­materials.­
Models­50DKR­&­75DKTR­are­not­suitable­for­use­on­wood­
floors­or­other­combustible­materials.­When­used,­the­heater­
should­rest­on­suitable­insulating­material­at­least­1­inch­
thick­and­extending­3­ft.­or­more­beyond­the­heater­in­all­
directions.
HEATER START UP
1.­ 50DKR:­Plug­the­heater­into­a­grounded­1 15V,­60­Hz,­1­Ø­
outlet.
75DKTR, 125DKTR, 175DKTR: Turn­thermostat­to­lowest­
setting,­make­sure­"On/Off"­switch­is­"Off".­Plug­the­heater­
into­a­grounded­1 15V,­60­Hz,­1­Ø­outlet.­Turn­thermostat­
to­highest­setting.­Start­heater­by­pushing­toggle­switch­
to­"On"­position­(light­signifies­switch­is­in­"ON"­position).­
Adjust­thermostat­to­desired­setting.­Heater­will­cycle­on/off­
as­heat­is­required.
EXTENSION­CORD­REQUIREMENTS:­Up­to­100'­(30.5m)­use­
16­awg.­conductor.­101'­-­200'­(30.5­-­61.0m)­use­14­awg.­
conductor.
For all models:
•­ In­cold­weather­(below­10°­F),­starting­may­be­improved­by­
holding­a­finger­over­the­vent­hole­of­the­pump­adjustment­
screw­cap­until­the­heater­starts.­
•­ This­unit­is­equipped­with­an­interrupt­circuit.­The­reset­is­
integrated­into­the­"On/Off"­switch.­If­the­unit­does­not­
start,­toggle­the­switch­to­"Off",­wait­5­min.­and­toggle­
the­switch­to­"On".
HEATER SHUT DOWN
1.­ 50DKR: Unplug­heater­from­power­source.
75DKTR, 125DKTR, 175DKTR: Push­"On/Off"­switch­to­
"Off"­position.­For­extended­shutdown,­unplug­heater­from­
power­source.

MAINTENANCE AND STORAGE
WARNING.­To­prevent­personal­injury,­unplug­the­heater­from­
the­wall­outlet­before­servicing.­
For­maximum­efficiency­and­trouble-free­service,­make­the­
following­periodic­maintenance,­cleaning­and­inspections.
ADJUSTING PUMP PRESSURE
Due­to­varying­fuel­viscosities­and­normal­component­wear­the­
pump­pressure­on­this­heater­may­need­to­be­adjusted.­­
Pressure­Adjustment­Screw­(located­at­the­rear­of­the­heater)
ADJUSTMENT­PROCEDURE:
1.­ Fill­fuel­tank.
2.­ Start­heater.
3.­ Locate­the­fuel­pressure­adjustment­screw­(ref.­#29)­in­the­
exploded­parts­drawing.­­The­pressure­adjustment­screw­
is­located­at­the­rear­of­the­heater,­in­the­air­filter­housing­
cover­(approx.2"­from­the­left­side­and­1"­from­the­top).­
Remove­and­discard­the­rubber­cap­(ref.­#4)­to­expose­the­
screw.
4.­ Using­a­flat­bladed­screw­driver,­turn­the­pump­pressure­
adjustment­screw­clockwise­to­increase­pump­pressure­and/
or­counter-clockwise­to­decrease­pump­pressure.­­Base­pump­
pressures­can­be­found­in­the­specifications­chart­on­page­3­
of­the­"Operating­Instructions­and­Owners'­Manual".
5.­ For­best­results,­the­nose­cone­in­the­combustion­chamber­
should­be­cherry­red­with­no­dark­spots­and­the­flame­
should­not­extend­beyond­the­nose­cone.
IMPROPER­PRESSURE­ADJUSTMENT
Problem: ­­ Heater­does­not­have­a­strong­consistent­flame.
­ ­ Heater­smokes­and­spits­raw­fuel.
­ ­ Nose­cone­does­not­get­cherry­red.
Adjustment:­Pump­pressure­is­too­low.­­
­ ­ Turn­adjustment­screw­clockwise­to­increase­pump­­
