Problem:­ Flame­extends­beyond­the­end­of­the­heater.
Adjustment:­Pump­pressure­is­too­high.­
­ ­ Turn­adjustment­screw­counter­clockwise­to­­
­ ­ decrease­pump­pressure.
DAILY SCHEDULE
1.­ GENERAL.­Make­general­visual­inspection­of­heater­for­loose­
or­damaged­parts.­Check­nuts­and­bolts­to­insure­against­
looseness­caused­by­vibration­or­rough­handling.­Damaged­
parts­should­be­repaired­or­replaced­before­using­heater­
again.­Check­heater­operation­to­be­sure­it­is­operating­
normally­(See­"Servicing"­section­for­description­of­normal­
operation).
2.­ FILTERS.­Dirty­air­or­fuel­filters­will­cause­an­imbalance­in­
the­air-fuel­mixture.­The­best­indication­that­this­condition­
exists­is­an­increase­in­odors­or­difficulty­getting­your­heater­
to­ignite.­This­heater­should­never­be­operated­without­the­
filters­in­place.­If­required,­clean­filters­as­described­under­
"500­Hours"­and­"Annual­Schedules".
500 HOUR SCHEDULE
1.­ AIR­INTAKE­FILTER.­Remove­and­wash­the­filter­element­
with­a­mild­detergent,­dry­thoroughly­and­replace.­Do­not­
oil­the­filter­element.­If­your­heater­is­used­where­there­
is­considerable­dust­or­dirt,­clean­as­often­as­necessary­
(approximately­every­50­hrs.).
2.­ REMOVE­DUST.­Clean­heater­twice­a­season­(more­often­
under­dusty­conditions).­Remove­accumulated­dust­from­the­
transformer,­burner,­motor­and­fan­blades­with­compressed­
air.­Wipe­area­clean­with­a­clean­dry­cloth.­Inspect­area­to­
insure­all­foreign­materials­are­removed,­especially­around­
the­burner­and­combustion­area.
3.­ CAD­CELL.­Clean­the­glass­portion­of­the­cad­cell­with­a­soft­
dry­cloth.
4.­ NOZZLE.­Accumulation­of­dirt­from­fuel­and­carbon­from­
the­compressor­vanes­will­eventually­fill­up­the­passages­
in­the­nozzle,­resulting­in­reduction­of­fuel­and­air­flow.­
Pressure­will­gradually­increase­giving­improper­fuel-air­
mixture­and­excess­odor­and­smoke.­If­this­occurs,­replace­
the­fuel­nozzle.
5.­ FUEL­TANK.­Clean­twice­a­season­(during­frequently­used­
periods,­clean­twice­a­month).­Drain­and­flush­the­fuel­tank­
with­clean­fuel­oil.
ANNUAL SCHEDULE
1.­ AIR­OUTPUT­FILTER.­Remove­the­air­output­filter­and­tap­
the­contaminated­side­gently­on­a­solid­object­to­remove­
contaminates.­Compressed­air­or­liquids­should­not­be­used­
to­clean­this­filter.­Reinstall­cleaned­filter­in­filter­body­in­the­
same­position­as­it­was­when­removed.­If­the­filter­appears­
extremely­dirty,­replace­it­with­a­new­filter­of­the­same­
type.­When­replacing­the­filter­cover,­be­sure­the­gasket­is­
firmly­in­place­and­the­screws­in­the­filter­cover­are­tight­to­
prevent­air­leaks.
2.­ FUEL­FILTER.­Remove­the­fuel­filter­from­fuel­line­and­direct­
compressed­air­through­the­filter­in­the­opposite­direction­
of­fuel­flow.­Safety­glasses­should­be­worn­when­using­
compressed­air.
3.­ AIR­AND­FUEL­LINES.­If­the­air­or­fuel­lines­are­removed­

STORAGE
Store­the­heater­in­a­dry­location­free­from­fumes­or­dust.
At­the­end­of­each­heating­season,­clean­the­heater­as­described­
in­the­MAINTENANCE­section.­Drain­and­flush­the­fuel­tank­with­
clean­fuel.­The­manufacturer­recommends­completely­filling­the­
tank­with­fuel­for­extended­storage­to­minimize­condensation­
inside­the­tank.
