Keep  com­

�-------_J bustibles  such  as  building  materials, 

paper  or  cardboard  a  safe  distance  away  from  the  heater  as 

recommended  by  these  instructions.  Never  use the  heater  in 

spaces which contain products such as gasoline, solvents, paiht 

thinners, dust particles, volatile or airborne combustibles or any 

unknown  chemicals.  This  is  an  unvented  portable  heater.  It 

uses air  (Oxygen)  from  the area in which  it is used. Adequate 

combustion  and  ventilation  air  must  be  provided.  Refer  to 

"Ventilation" on page 7.

THIS  HEATER

UNTIL  YOU  HAVE  READ  AND

'---------- THOROUGHLY 

UNDERSTAND 

THESE  SAFETY AND OPERATING INSTRUCTIONS. 

Failure

to  comply  with  the  precautions  and  instructions  provided  with 

this  heater  can  result  in  death,  serious  bodily  injury,  property 

loss or damage from the hazards of fire, soot production, explo­

sions,  burns, asphyxiation or carbon monoxide poisoning. Only 

persons who can read and understand these instructions should 

use or service this heater. 

CALIFORNIA RESIDENTS: 

This product contains 

chemicals, including lead, known to the State of California to 

cause birth defects 

.

or other reproductive harm. 

Wash hands 

after handling. 

MASSACHUSETTS RESIDENTS: 

Massachusetts 

state law prohibits the use of this heater in any building which 

is used in whole or in part for human habitation. Use of this 

heating device in Massachusetts requires local fire department 

permit (M.G.L.C. 148,  Section 1 0A). 

NEW YORK CITY RESIDENTS: 

The New York City 

Fire Code prohibits the storage, handling and use of kerosene 

fueled heaters for space heating. Any person violating that 

provision may be punished by a fine up to $10,000 and a term 

of imprisonment of up to 6 months.

Indicates a potentially hazardous 

A CAUTION 

situation which, if not avoided, MAY

result in minor or moderate injury. 

This is a kerosene direct-fired, forced air heater. Kerosene forced 

air heaters are primarily intended for use for temporary heating 

of buildings under construction, alteration or repair. Direct-fired 

means 

that 

all of the 

combustion 

products of the heater enter the 

heated 

space. 

This appliance 

is 

rated at 98% combustion efficiency, 

but does produce small amounts of carbon monoxide. Carbon 

monoxide is toxic. 

ADANGER 

CARBON MONOXIDE POISONING MAY 
LEAD TO DEATH! 

Humans can tolerate small amounts of carbon monoxide, and 

precautions 

should be taken 

to 

provide 

proper 

ventilation. Failure 

to 

provide 

proper 

ventila ion 

according 

to this manual can result 

in death. 

Early 

signs of 

carbon 

monoxide poisoning resemble the 

flu. 

Symptoms 

of 

improper 

ventilation 

are: Symptoms of improper 

venti

carbon monoxide poisoning are: 

Headache • Dizziness • Nausea• Dry Mouth Sore Throat• 

Burning of 

Nose and Eyes 

For 

optimal 

performance 

of 

this heater, 

it is 

strongly 

suggested 

that K-1 kerosene 

b

e

used. K-1 kerosene has been refined to 

virtually eliminate contaminants, such as sulfur, which can cause 

a rotten 

egg 

odor during the 

operation of the heater. However, #1 

or #2 fuel 

oil (diesel fuel) may 

also 

be used if K-1 

kerosene is not 

available. Be advised that these fuels do not burn as clean as K-1 

kerosene, and care should be taken to provide more fresh air 

ventilation to accommodate any added contaminants that may be 

added to the heated space.  Use of #1 or #2 fuel oil may result in 

more periodic maintenance. 

A WARN 

N G 

Risk of indoor air pollution!

- Use this heater only in well ventilated areas! Provide, at heater

level, at least a three squ

.

are foot (2,800 sq. cm) opening of 

outside air for every 100,000 BTU/hr of heater rating. 

- People with breathing problems should consult a physician

before using the heater. 

- Carbon Monoxide Poisoning: Early signs of 

carbon

.

monoxide

poisoning resemble flu-like symptoms such as headaches,

dizziness, and/or nausea. If you have these symptoms, your

heater may not be working properly.

- Get fresh air at once! Have the heater serviced. Some people

are more affected by carbon monoxide than others. These include

pregnant women, those with heart or lung problems, anemia, or

those under the influence of alcohol, or at high altitudes.

A. 

WARNING 

Risk of burns/fire/explosion!

-

.

Nl�:VER use fuels such as gasoline, benzene, paint thinners, 

crankcase drainings, or other oil compounds in this heater (RISK 

OF FIRE OR EXPLOSION).
