Look for this icon throughout the manual for helpful tips on how to
assemble, use and clean your OFR/SS Heater.
Read The Instruction manual: When this symbol is
marked on a product, it means that the instruction
Parafn/Diesel direct-red, forced air heaters.
Parafn/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
efciency, but does produce small amounts of
carbon monoxide.
CARBON MONOXIDE POISONING
MAY LEAD TO DEATH!
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.
strongly suggested that Parafn be used.
Parafn has been rened 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 parafn, no. 1 &
no.2 diesel, JP8/Jet A Fuel, no. 1 and no. 2
fuel oil.
NEVER REFUEL THIS HEATER
WHILE IT IS HOT OR
OPERATING. FIRE OR EXPLOSION COULD
RESULT.
NEVER FILL THE FUEL TANK
INDOORS. ALWAYS FILL
THE TANK OUTDOORS. BE SURE THAT
THE HEATER IS ON LEVEL GROUND WHEN
FUELING, AND NEVER OVERFILL THE TANK.
DO NOT USE GASOLINE OR
CRANKCASE DRAININGS.
NOTE: Parafn should only be stored in
a blue container that is clearly marked
“Parafn.” Never store Parafn 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 (100,00 Btu / Hr.) of
heater output. Provide a larger opening if more
heaters are being used.
CARBON MONOXIDE POISONING
MAY LEAD TO DEATH!
This appliance is designed to
operate safely at a minimum
ambient temperature of -20° C.
- NEVER use fuel such as, benzene, alcohol, white
glass, 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.
wet areas. Disconnect power
from the power mains and keep all electrical
components from becoming wet. Only a
qualified technician should service the
heater
A qualified technician is
required to install, adjust and
where necessary; convert this heater for use
with other fuel types.
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.
3. Connect the heater to a three prong
(grounded) power source. You must use a
three prong (grounded) extension cord that is
at least 1.8 meters long and is a minimum of
14 AWG rating.
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.
Stopping the Heater: (Cool Down)
1. Turn the power switch to the “OFF” position.
Combustion will stop and the Cooling Cycle
will begin.
- PT-70-SS-EU / PT-70T-SS-EU: approx. 7 mins
- PT-125-OFR-EU: 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.
DO NOT disconnect heater
from power source before
cooling cycle has been completed.
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)
NOTE: NEVER MIX WATER WITH FUEL. It will
cause rust inside the tank.
4. Empty the tank completely.
IMPORTANT: Never store leftover Parafn
between seasons, using old fuel can
damage heater.
Store Heater in a dry, well ventilated area.
-Be sure that the storage area is free of dust
and corrosive vapors. Repack the heater
in the original packaging and keep user’s
manual in an easily accessible place.
Service:
DO NOT TAMPER WITH THE UNIT. HAVE AN
EXPERIENCED SERVICEMAN MAKE ANY
NECESSARY ADJUSTMENT OR REPAIRS.
Never service heater while it is
plugged in or hot!
We suggest following a maintenance schedule as
follows:
FUEL / FUEL TANK:
Flush tank every 200 hours of operation or as
needed. DO NOT ush with water, use fresh
Parafn only.
TIP: Follow the long term storage
instructions to ush the tank.
SPARK PLUG:
Clean and re-gap every 600 hours of operation
or replace as needed. After removing the Spark
Plug, clean the terminals with a wire brush.
Re-gap the terminals to 0.140” (3.5mm).
(See Figure 7)
Figure 7
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 8)

PT-70-SS-EU / PT-70T-SS-EU
PT-70-SS-EU / PT-70T-SS-EU / PT-125-OFR-EU
PRESSURE ADJUSTMENTS:
Proper pressure is dependent on the fuel type
the unit will be running. When smoking or nonignition occurs, remove the lower panel. Locate
the brass screw on the fuel pump to the left of the
fuel line.
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
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 Parafn or diesel to help loosen any
particles. (See Figure 9)
PT-70-SS-EU / PT-70T-SS-EU Nozzle
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 10)

FILTERS:
The fuel filter and oil filter should be cleaned at
least twice per heating season by rinsing it in
clean Paraffin or diesel. Contaminated or old fuel
could make cleaning necessary immediately.
