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.
Use this heater in only well ventilated areas!
Provide at least a three square foot
(2,800 cm2) opening of outside air for every
29 kW / Hr heater rating. Refer to “Ventilation”
on page 7 for further instructions.
ALWAYS use only the electrical power (voltage and
frequency) specified on the model plate of the heater.
ALWAYS use only properly grounded socket and
properly rated extension cables.
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.
If the supply cord is damaged, it must be
replaced by a special cord or assemble available
from the manufacturer, its service agent or
similarly qualied persons in order to avoid a
hazard
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 inlet (rear) or air outlet (front).
NEVER use duct work in front or rear of heater.
NEVER move or handle heater while still hot.
NEVER transport heater with fuel in tank.
NEVER use with an external fuel tank.
Keep all combustible materials away from this heater.
Minimum Clearance From Combustibles

Operation
Fueling The Heater:
Parafn
For optimal performance of this heater, it is
strongly suggested that Kerosene 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 as this fuel will
damage your heater’s seals and lter.
- 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. Paraffin 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 1-2 for
information about Carbon Monoxide Poisoning.
- ALWAYS provide a fresh air opening in the heated
space of at least 2,800 cm
2
(3 sq. ft) for each 29 kW / Hr. of heater output.
Provide a larger opening if more heaters are being
used.
As an example, a PT-125 SS will require:
- A two car garage door open 16 cm or
- A single car garage open 22 cm or
- Two (2) 82 cm windows open 38.5 cm
Minimum Ventilation Opening Needed

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.
CAUTION
NEVER REFUEL THIS HEATER
WHILE IT IS HOT OR
OPERATING. FIRE OR EXPLOSION COULD
RESULT.
DANGER
CARBON MONOXIDE POISONING
MAY LEAD TO DEATH!
DANGER
7
DO NOT USE GASOLINE OR
CRANKCASE DRAININGS.
WARNING
This appliance is designed to
operate safely at a minimum
ambient temperature of -20° C.
WARNING
Use caution when servicing in
wet areas. Disconnect power
from the power mains and keep all electrical
components from becoming wet. Only a
qualified technician should service the
heater
WARNING
A qualified technician is
required to install, adjust and
where necessary; convert this heater for use
with other fuel types.

Operation: PT70-SS Plus / PT-125 SS
Starting the Heater: (Ignition)
1. Fill the tank with Kerosene or other approved
fuel.
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: 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.
- PT70-SS Plus: approx. 7 mins
- PT-125 SS: 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.

Maintenance - PT70-SS Plus
Long Term Storage:
1. Unscrew the fuel cap.
2. Using an approved siphon (Figure 11.1),
remove the Kerosene or diesel.
3. Using a small amount of Kerosene or diesel,
rinse and swirl the fuel inside the fuel tank
NOTE: NEVER MIX WATER WITH FUEL. It will
cause rust inside the tank.
4. Empty the tank completely.
IMPORTANT: Never store leftover Kerosene
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.
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
Kerosene only.
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 11.2)
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 12)

Service (Continued):
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 parafn or diesel to help loosen any
particles. (See Figure 13)
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 14)
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.
