PREPARING FOR OPERATION
1.­ Check­the­heater­for­possible­shipping­damage.­If­any­is­
found,­immediately­contact­the­manufacturer­at­
800-251-0001.
2.­ Follow­all­of­the­"Precautions".­
3.­ Fill­the­fuel­tank­with­clean­kerosene.­In­extremely­cold­
weather,­condensation­may­develop­in­the­tank­and­it­is­
recommended­that­a­tablespoon­of­de-icer­be­added­for­
each­gallon­(3.78­Liters)­of­fuel­in­the­tank.­When­filling­the­
heater,­use­at­least­2­gallons­(7.57­liters)­of­fuel.­Be­sure­
heater­is­level­and­do­not­overfill.­Use­a­funnel­or­can­with­a­
long­fill­spout.
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.­
Models­MH50KR­&­MH80KTR­are­not­suitable­for­use­on­
wood­floors­or­other­combustible­materials.­When­used,­the­
heater­should­rest­on­suitable­insulating­material­at­least­1­
inch­thick­and­extending­3­ft.­or­more­beyond­the­heater­in­
all­directions.
HEATER START UP
1.­ MH50KR:­Plug­the­heater­into­a­grounded­115V,­60­Hz,­1­
Ø­outlet.
MH80KTR, MH140KTR, MH185KTR & MH210KTR: Turn­
thermostat­to­lowest­setting,­and­make­sure­"On/Off"­
switch­is­"Off".­Plug­the­heater­into­a­grounded­115V,­60­
Hz,­1­Ø­outlet.­Turn­thermostat­to­highest­setting.­Start­
heater­by­pushing­toggle­switch­to­"On"­position­(light­
signifies­switch­is­in­"ON"­position).­Adjust­thermostat­to­
desired­setting.­Heater­will­cycle­on/off­as­heat­is­required.
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.­ MH50KR: Unplug­heater­from­power­source.
MH80KTR, MH140KTR, MH185KTR & MH210KTR: Push­
"On/Off"­switch­to­"Off"­position.­For­extended­shutdown,­
unplug­heater­from­power­source.

MAINTENANCE AND STORAGE
WARNING.­To­prevent­personal­injury,­unplug­the­heater­from­
the­wall­outlet­before­servicing.­
For­maximum­efficiency­and­trouble-free­service,­make­the­
following­periodic­maintenance,­cleaning­and­inspections.
ADJUSTING PUMP PRESSURE
Due­to­varying­fuel­viscosities­and­normal­component­wear­the­

ADJUSTMENT­PROCEDURE
1.­Fill­fuel­tank.
2.­Start­heater.
3.­Locate­the­pressure­adjustment­screw­and­pressure­tap,­
pictured­above,­located­on­the­back­of­the­power­pack­
assembly­and­accessible­by­the­handle­of­the­heater.
4.­Remove­and­the­rubber­cap­over­the­fuel­pressure­adjustment­

5.­Using­a­flat­bladed­screw­driver,­turn­the­pump­pressure­
adjustment­screw:
•­clockwise­ ­to­increase­pump­pressure
•­counter-clockwise­
By­using­the­installed­pressure­gauge­you­may­quantitatively­
calibrate­the­pressure.­The­manufacturer's­recommended­pump­
pressures­are­in­the­specifications­chart­on­page­3.
6.­The­desired­qualitative­burner­characteristics­are­that­the­nose­
