Safety Information
The products described in this manual are
Parafn/Diesel direct-red, forced air heaters.
Parafn/Diesel forced air heaters are primarily
intended for use for temporary heating of
buildings under construction, alteration or repair.
Direct-red means that all of the combustion
products of the heater enter the heated space.
This appliance is rated at 98% combustion
ef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 u. 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 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.
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 2,800 sq. cm (3 sq. ft.)
opening of outside air for every 29 kW( 100,000
Btu/Hr) heater rating. Refer to “Ventilation” on
page 8 for further instructions.
ALWAYS use only the electrical power (voltage and
frequency) specified on the model plate of the heater.
ALWAYS use only three-prong, grounded outlet and
extension cord.
ALWAYS use only 14 AWG or better extension cord.
ALWAYS unplug the heater when not in use.
ALWAYS install the heater so that it is not directly
exposed to water spray, rain, dripping water, or wind.
NEVER use fuels such as gasoline, benzine, paint
thinners or other oil compounds in this heater.
NEVER refill the heater’s fuel tank while the
heater is operating or still hot. This heater is
EXTREMELY HOT while in operation.
NEVER block air outlet (front).
NEVER use duct work in front of heater.
NEVER move or handle heater while still hot.
NEVER transport heater with fuel in tank.
NEVER use with an external fuel tank.

Operation
Fueling The Heater:
Parafn
For optimal performance of this heater, it is
strongly suggested that Parafn be used.
Parafn has been rened 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 or Farm “red”
diesel as this fuel will damage your heater’s seals
and lter.
Factory tested for use with parafn, 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 Paraffin in the living space. Paraffin
should be stored in a well ventilated area outside
the living area.
- NEVER store Paraffin in direct sunlight or near a
source of heat.
- NEVER use Paraffin that has been stored from one
season to the next. Paraffin deteriorates over time.
OLD Paraffin WILL NOT BURN PROPERLY IN
THIS HEATER.
NOTE: Parafn should only be stored in
a blue container that is clearly marked
“Parafn.” Never store Parafn 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 1-2 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 29 kW (100,000 Btu / Hr.) of
heater output. Provide a larger opening if more
heaters are being used.

WHILE IT IS HOT OR
OPERATING. FIRE OR EXPLOSION COULD
RESULT.

Operation: ST-70-SS-E / ST-70T-SS-E / ST-125-OFR-E
Starting the Heater: (Ignition)
1. Fill the tank with Paraffin or other approved
fuel until needle on fuel gauge points to “F”.
2. Replace fuel cap and tighten firmly.
NOTE: On first ignition or after refueling,
you may hear a grinding sound just before
ignition. This is the fuel pump removing the
air from the fuel line. Your heater will start up
within seconds. If it does not start repeat
start-up procedures with fuel gauge reading at
least 1/2 tank.
NOTE: Smoking may occur on first ignition.
NOTE: The electrical components of these
heaters are protected by a fuse mounted
in the PC board. If the heater fails to ignite,
check this fuse first and replace if necessary.
Also check the power source to be sure the
proper voltage is being provided to the heater.
1. Complete steps 1-3 above.
2. Push the power switch to the “ON” position.
The power indicator lamp will light and heater
will ignite. (See Figure 5)
Stopping the Heater: (Cool Down)
1. Turn the power switch to the “OFF” position.
Combustion will stop and the Cooling Cycle
will begin.
- ST-70-SS-E / ST-70T-SS-E: approx. 7 mins
- ST-125-OFR-E: approx 3 mins
When the Cooling Cycle is complete the fan
will stop running and it will be safe to unplug
the heater.
NOTE: Unplugging the heater before the
Cooling Cycle has been completed may cause
overheating, possible damage to the heater and
heat plate.
Restarting the Heater:
1. Wait ten seconds after Cooling Cycle has
been completed.
2. Follow all start-up procedures above.
