SAFETY INFORMATION

WARNING: This product con­tains and/or generates chemicals
known to the State of California
to cause cancer or birth defects
or other reproductive harm.

IMPORTANT: Read this owner’s
manual carefully and completely
before trying to assemble,
operate or service this heater.
Improper use of this heater can
cause serious injury or death
from burns, fire, explosion,
electrical shock and carbon
monoxide poisoning.

DANGER: Carbon monoxide
poisoning may lead to death!

Carbon Monoxide Poisoning: Early signs of carbon

monoxide poisoning resemble the flue, with head
aches, dizziness and/or nausea. If you have these
signs, the heater may not be working properly. Get
fresh air at once! Have heater serviced. Some people
are more affected by carbon monoxide than others.
These include pregnant women, persons with heart
or lung disease or anemia, those under the influence
of alcohol and those at high altitudes.

Make certain you read and understand all warn­ings. Keep this manual for reference. It is your
guide to safe and proper operation of this heater.

1. Use only kerosene, #1#2 diesel/fuel oil, JET A
or JP-8 fuels to avoid risk of fire or explosion.
Never use gasoline, naphtha, paint thinners,
alcohol or other highly flammable fuels.

2. Fueling

a) Personnel involved with fueling shall be

qualified and thoroughly familiar with the
manufacturerʼs instructions and applicable
regulations regarding the safe fueling of
heating units.

b) Only the type of fuel specified on the

heaterʼs data plate shall be used.

c) All flame, including the pilot light, if any,

shall be extinguished and the heater al
lowed to cool, prior to fueling.

d) During fueling, all fuel lines and fuel-line

connections shall be inspected for leaks.
Any leaks shall be repaired prior to return
ing the heater to service.

2

www.desatech.com

e) At no time shall more than one dayʼs supply

of heater fuel be stored inside a building in
the vicinity of the heater. Bulk fuel storage
shall be outside the structure.

f) All fuel storage shall be located a minimum

of 25 feet (762cm) from heaters, torches,
welding equipment and similar sources
of ignition (exception: the fuel reservoir
integral with the heater unit).

g) Whenever possible, fuel storage shall be

confined to areas where floor penetrations
do not permit fuel to drip onto or be ignited
by a fire at lower elevation.

h) Fuel storage shall be in accordance with

the authority having jurisdiction.

3. Use only the electrical voltage and frequency
specified on model plate.

4. Heater must be grounded. Use only a properly
grounded three-wire extension cord. Plug into
grounded outlet only.

5. Use only in areas free of flammable vapors or
high dust content.

6. Minimum clearance from any combustible
materials: 8 feet (244 cm) from hot air outlet;
4 feet (122 cm) from top; and 4 feet (122 cm)

­from sides and inlet.

7. Locate heater on a stable and level surface
while hot or operating or a fire may occur.

8. Use only in well-vented areas. Before using
heater, provide at least a three-square-foot
(2800 square cm) opening of fresh, outside air
for each 100,000 Btu/Hr (30 kw) of rating.

9. Keep children and animals away from heater
at all times.

10. Never start heater when combustion chamber
is hot or if fuel has accumulated in combustion
chamber.

11. When used with thermostat, heater may start
at anytime.

12. When heater is moved or stored, it must be in
a level position or fuel spillage may occur.

13. Use heater only in accordance with local
ordinances and codes.

14. Never use gasoline, crankcase drainings,
naphtha, paint thinners, alcohol or other highly
flammable fuels.

15.

Never use heater where gasoline, paint thinner
or other highly flammable vapors are present.

-

16. Never use heater in living or sleeping areas.

17. Never leave a heater plugged in without adult
supervision if children or animals are likely to
be present.

18. Never move, handle, refuel or service a hot,
operating or plugged-in heater.

19. Never attach heater to external fuel tank.

20. Heaters used in the vicinity of tarpaulins,
canvas or similar enclosure materials shall be
located a safe distance from such materials.
The recommended minimum safe distance is
10 feet (304.8 cm). It is further recommended
that these enclosure materials be of a fire
retardant nature. These enclosure materials
shall be securely fastened to prevent them
from igniting or from upsetting the heater due
to wind action.

21. Unplug heater when not in use.

22. Never block air inlet (rear) or air outlet (front)
of heater.

FUELS

WARNING: Use only kero­sene, #1/#2 diesel/fuel oil, JET A
or JP-8 fuels to avoid risk of fire or
explosion. Never use gasoline, oil
drained from crankcases, naph­tha, paint thinners, alcohol or
other highly flammable fuels.

Use only kerosene, #1/#2 diesel/fuel oil, JET A
or JP-8 fuels. Heavier fuels such as No. 2 fuel
oil or No. 2 diesel fuel may also be used but will
result in:

• noticeable odor

• additional fuel filter maintenance

• the need for nontoxic, anti-icer additives in very
cold weather

Do not use fuels heavier than No. 2 grade or
heavy oils such as oil drained from crankcases.
These heavy oils will not ignite properly and will
contaminate the heater.

IMPORTANT: Use a KEROSENE ONLY (blue)
or DIESEL ONLY (yellow) storage container. Be
sure storage container is clean. Foreign matter
such as rust, dirt or water will cause the ignition
control assembly to shut down heater. Foreign
matter may also require heaterʼs fuel system to
be frequently cleaned.

TO START HEATER

IMPORTANT: Review and under­stand the warnings in the
Information section, page 2. They
are needed to safely operate
this heater. Follow all local or­dinances and codes when using
this heater.

1. Fill tank with fuel (see Fuels).

2.

Plug heater power cord into approved, grounded,

120V/60Hz, 3 prong outlet or extension cord.
Extension Cord Size Requirements
6 to 10 feet (1.8 to 3 meters) long, use 18 AWG

(0.75 mm2) rated cord
11 to 100 feet (3.3 to 30.5 meters) long, use

16 AWG (1.0 mm
101 to 200 feet (30.8 to 61 meters) long, use

14 AWG (1.5 mm

3. If a thermostat is connected, adjust it to the

maximum temperature.

Safety

4.

Flip switch (3 on Electric Control Panel,
page 7) to the position with the symbol:

- the fan should start and after several

seconds the heater should ignite.

The first time the heater is used or after the fuel
circuit has been completely drained, the flow of
fuel oil to the nozzle may be insufficient and may
activate the flame control, which will turn off the
heater; if this happens, wait for about a minute and
then press the reset button (1
Panel, page 7

) to start the heater again.

on Electric Control

TO STOP HEATER

1.

Move switch (3 on Electric Control Panel, page

7) to the “0” position or adjust the control mech
anism, for example turning the thermostat to a
lower position. The flame will go out and the fan
will continue to function until the combustion
chamber has cooled down completely.

2. Wait until fan stops before unplugging heater.
Unplug heater when not in use.

THERMOSTAT

OPERATION

The heater can only work automatically when a
thermostat is connected to it by attaching the cable
to terminals 2 and 3 of plug (4
Panel, page 7

).

on Electric Control

MOVING AND

TRANSPORTING HEATER
