WARNING
The products described in this manual are
kerosene direct-fired, forced air heaters. 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 eciency, but does produce small
amounts of carbon monoxide.
Carbon monoxide is toxic. Humans can tolerate
only small amounts of carbon monoxide and so
precautions should be taken to provide proper
ventilation. Failure to provide proper ventilation in
accordance with the instructions in this manual can
result in death.
People with breathing problems should consult
a physician before using this heater. Early signs
of carbon monoxide poisoning resemble the
flu. Symptoms of improper ventilation/carbon
monoxide poisoning are:
Headache • Dizziness •Nausea • Dry Mouth
Sore Throat • Burning of Nose and Eyes
If you experience any of these symptoms:
GET FRESH AIR AT ONCE! Have your heater
serviced and check for proper ventilation. Some
people are more aected 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.
FOR OUTDOOR USE. INDOOR USE PERMITTED
ONLY FOR: The temporary heating of adequately
ventilated buildings or structures under
construction, alteration or repair! Provide at
least a three square foot (2,800 sq cm) opening
of outside air for every 100,000 Btu/Hr (29 kW)
heater rating. Refer to “Ventilation” on page 7 for

OR WHILE CONNECTED TO A POWER SOURCE
OPERATION
Fueling The Heater:
Kerosene
For optimal performance of this heater, it is
strongly suggested that Kerosene be used.
Kerosene has been refined to virtually eliminate
contaminants, such as sulfur, which can cause
a rotten egg odor during the operation of the
heater. Using diesel fuel can cause excess soot
production. Do not use Bio-Diesel as this fuel will
damage your heater’s seals and filter.
- CSA certified for use with K-1 kerosene, no. 1 & no. 2
diesel, JP8/Jet A Fuel, no. 1 and no. 2 fuel oil.
- NEVER use fuel such as, benzene, alcohol, white gas,
camp stove fuel, paint thinners, or other oil
compounds in this heater. THESE ARE VOLATILE
FUELS THAT CAN CAUSE A FIRE OR EXPLOSION.
- NEVER store Kerosene in the living space. Kerosene
should be stored in a well ventilated area outside
the living area.
- NEVER store Kerosene in direct sunlight or near a
source of heat.
- NEVER use Kerosene that has been stored from one
season to the next. Kerosene deteriorates over
time. OLD Kerosene WILL NOT BURN PROPERLY
IN THIS HEATER.
NOTE: Kerosene should only be stored in a blue
container that is clearly marked “Kerosene.”
Never store Kerosene in a red container. Red is
associated with gasoline.
Ventilation:
- Risk of indoor air pollution and Carbon Monoxide
Poisoning. Use heater only in well ventilated
areas.
- Refer to Safety Information on pages 2-3 for
information about Carbon Monoxide Poisoning.
- ALWAYS provide a fresh air opening in the heated
space of at least 2,800 square centimeters
(3 sq. ft) for each 100,00 Btu/Hr. (29 kW) of heater
output. Provide a larger opening if more heaters are
being used.

Service (Continued):
FAN BLADES:
The fan blades should be cleaned at least once
per heating season, depending on conditions.
Remove all accumulated dust and dirt with a
burst of condensed air (see Figure 13).
PRESSURE ADJUSTMENTS:
Proper pressure is dependent on the fuel type the
unit will be running. When smoking or non-ignition
occurs, remove the lower panel. Locate the Phillips
screw with a nut on the fuel pump to the left of the
fuel line. There is a small “P” next to the pressure
screw. The ideal pressure is 112 psi (7.9 kg/cm2).
If you are experiencing smoking or fuel dripping
from the unit, turn the screw clockwise 1/8 to 1/4
of a turn to increase the fuel pressure until the
unit is operating properly.
If you are experiencing extended flames from
the front of the unit, turn the screw 1/8 to 1/4 of a
turn counterclockwise to reduce the air pressure
until the unit is operating properly.
NOZZLES:
Nozzles should be cleaned or replaced at least
once per heating season. Contaminated fuel
could make this necessary immediately. To clean
dirt from nozzle, blow compressed air through
nozzle front. It may be necessary to soak nozzle
in clean Kerosene or diesel to help loosen any
particles (see Figure 14a and 14b).
PHOTOCELL:
The photocell should be cleaned at least once
per heating season or more depending on
conditions. Use a cotton swab and water or
alcohol to clean the lens of the photocell.
Be certain to reinstall the photocell in proper
position as shown below (see Figure 15).
FILTERS:
The fuel filter and oil filter should be cleaned at
least twice per heating season by rinsing it in
clean Kerosene or diesel. Contaminated or old
fuel could make cleaning necessary immediately.
(see Figure 16).

Les produits décrits dans ce manuel sont des chauerettes
à feu direct et à air pulsé alimentées au kérosène. Les
chauerettes à air forcé au kérosène sont principalement
destinées au chauage temporaire des bâtiments en cours
de construction, de modification ou de rénovation. Feu
direct signifie que tous les produits de combustion de la
chauerette entrent dans l’espace chaué. Cet appareil
est évalué à 98% de rendement de la combustion, mais il
produit de petites quantités de monoxyde de carbone.
Le monoxyde de carbone est toxique. Les êtres humains
peuvent en tolérer seulement de petites quantités; des
précautions doivent donc être prises pour assurer une
ventilation adéquate. Une ventilation non adéquate, en
violation des consignes figurant dans ce manuel, peut
entraîner la mort.
Les personnes atteintes de problèmes respiratoires doivent
consulter un médecin avant d’utiliser cet appareil. Les
premiers signes d’intoxication au monoxyde de carbone
ressemblent aux symptômes de la grippe. Les symptômes
d’une mauvaise ventilation ou d’un empoisonnement au
monoxyde de carbone sont:
Mal de tête • Étourdissement • Nausée • Bouche sèche
Mal de gorge • Nez et yeux qui brûlent
Si un ou plusieurs de ces symptômesapparaissent :
SORTIR IMMÉDIATEMENT RESPIRER DE L’AIR FRAIS!
Faire vérifier ou réparer la chauerette et vérifier que la
ventilation est adéquate. Certaines personnes sont plus
aectées que d’autres par le monoxyde de carbone.
Celles-ci incluent: les femmes enceintes, les personnes
ayant des problèmes cardiaques ou pulmonaires, sourant
d’anémie ou qui se trouvent sous l’influence de l’alcool ou à
haute altitude.
POUR USAGE EXTÉRIEUR. USAGE INTÉRIEUR PERMIS
SEULEMENT POUR: le chauage temporaire des
structures ou des bâtiments bien ventilés en cours de
construction, de modification ou de réparation! Fournir
une ouverture d’au moins 2800cm sur l’air extérieur
pour chaque 100000 BTU/h (29 kWh) du régime nominal
de la chauerette. Voir la section «Ventilation» à la page
7 pour plus de détails.
