SAFETY INFORMATION

WARNING: This product con-

tains 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 warn-

ings. 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.

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.

3114909-01A

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 (304.8cm). 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.

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

on Electric Control

Panel, page 7

) to start the heater again.

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

on Electric Control

Panel, page 7

).

MOVING AND

TRANSPORTING HEATER

WARNING: Before moving

the heater you must turn the

heater off (see To Stop Heater),

disconnect the plug from the

power supply and wait for the

heater to cool.

Before lifting or moving the heater, make sure that

the fuel tank cap is ﬁrmly in place.

The heater may be supplied in a portable version,

with wheels or a suspended version, mounted on a

support structure and ﬁxed in place with wires or

chains. In the former case, to move the heater, sim

-

ply grasp the support handle and move the heater.

In the latter case, the heater must be lifted with a

fork-lift truck or a similar piece of equipment.

FUELS

WARNING: Use only kero-

sene, #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, naph-

tha, 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

stand the warnings in the

Safety

Information section, page 2. They

are needed to safely operate

this heater. Follow all local or-

dinances and codes when using

this heater.
