OPERATING PRECAUTIONS

This­is­a­kerosene,­direct-fired,­forced­air­heater.­It's­intended­use­
is­primarily­temporary­heating­of­buildings­under­construction,­
alteration­or­repair.
Direct-Fired­means­that­all­of­the­combustion­products­enter­the­
heated­space.­Even­though­this­heater­operates­very­close­to­100­
percent­combustion­efficiency,­it­still­produces­small­amounts­of­
carbon­monoxide.­Carbon­monoxide­(called­CO)­is­toxic.­CO­can­
build­up­in­a­heated­space­and­failure­to­provide­adequate­ventila-
tion­could­result­in­death.­The­symptoms­of­inadequate­ventilation­
are:
•­ headache­
•­ dizziness
•­ burning­eyes­and­nose­
•­ nausea
•­ dry­mouth­or­sore­throat
Be­sure­to­follow­advice­about­ventilation­in­the­Safety­Precautions­
section.
Forced­Air­means­that­a­blower­or­fan­pushes­the­air­through­the­
heater.­Proper­combustion­depends­upon­this­air­flow;­therefore,­
the­heater­must­not­be­revised,­modified­or­operated­with­parts­
removed­or­missing.­Likewise,­safety­systems­must­not­be­circum-
vented­or­modified­in­order­to­operate­the­heater.
When­the­heater­is­to­be­operated­in­the­presence­of­other­people­
the­user­is­responsible­for­properly­acquainting­those­present­
with­the­safety­precautions­and­instructions,­and­of­the­hazards­
involved.
