Introduction
THANK YOU for purchasing a John Deere product.
READ THIS MANUAL carefully to learn how to
operate and service your machine correctly. Failure
to do so could result in personal injury or equipment
damage.
THIS MANUAL SHOULD BE CONSIDERED a
permanent part of your machine and should remain
with the machine when you sell it.
MEASUREMENTS in this manual are given in both
metric and customary U.S. unit equivalents. Use only
correct replacement parts and fasteners. Metric and
inch fasteners may require a specific metric or inch
wrench.
RIGHT-HAND AND LEFT -HAND sides are determined
by facing in the direction the machine or implement
will travel when going forward.
WRITE PRODUCT IDENTIFICATION NUMBERS
(P.I.N.) in
Serial Number Identification,
page 25.
Accurately record all the numbers to help in tracing
the machine should it be stolen. Your dealer also
needs these numbers when you order parts. File the
identification numbers in a secure place off the
machine.
WARRANTY is provided as part of John Deere’ s
support program for customers who operate and
maintain their equipment as described in this manual.
The warranty is explained on the warranty certificate
which you should have received from you dealer.
This warranty provides you the assurance that John
Deere will back its products where defects appear
within the warranty period. In some circumstances,
John Deere also provides field improvements, often
without charge to the customer, even if the product is
out of warranty. Should the equipment be abused, or
modified to change its performance beyond the
original factory specifications, the warranty will become void and field improvements may be denied.
Setting fuel delivery above specifications or otherwise
overpowering machines will result in such action.

Operation
ELECTRICAL SUPPLY
CAUTION: If an additional electrical outlet is
needed to operate your heater, it should be
installed by a qualified electrician and the
installation should conform to the applicable codes and governing requirements.
The heater requires a grounded 120-volt, 60-hertz
receptacle for a power source. If necessary, use an
appropriate grounding adapter to connect to a twoprong receptacle. Check heater amperage requirements in
IMPORTANT: DO NOT overload circuit.
Specifications,
page 24 .

107351-01C
FILLING FUEL TANK
CAUTION: DO NOT add fuel while the heater is
hot or operating. DO NO T use diesel, No. 2 fuel
oil, gasoline, crank case drainings, naphtha,
paint thinner, alcohol, or other highly volatile
fuels. To xic fumes could be created by using
non-recommended fuels.
Operation
Remove cap (A) from fuel tank and fill with kerosene
or No. 1 fuel oil.
Do not use heavy fuels such as No. 2 fuel oil or No. 2
Diesel. Using heavy fuels will result in:
• clogged fuel filter and nozzle due to fuel gelling
• carbon build up on spark plug
Do not use No. 3 fuel oil or heavy oils such as crank
case drainings. These heavy oils will not ignite
properly and will contaminate the heater.
Fueling
• Personnel involved with fueling shall be qualified
and thoroughly familiar with the manufacturer’s
instructions and applicable federal, state, and local
regulations regarding the safe fueling of heating units.
• Only the type of fuel specified on the heater’s
data plate shall be used.
• All flame, including the pilot light, if any, shall be
extinguished and the heater allowed to cool, prior to
fueling.
• During fueling, all fuel lines and fuel-line connections shall be inspected for leaks. Any leaks shall
be repaired prior to returning the heater to service.
• At no time shall more than one day’s supply of
heater fuel be stored inside a building in the vicinity
of the heater. Bulk fuel storage shall be outside the
structure.
• All fuel storage shall be located a minimum of 25
feet (7.62 m) from heaters, torches, welding equipment, and similar sources of ignition (exception: the
fuel reservoir integral with the heater unit).
• 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.
• Fuel storage shall be in accordance with the
federal, state, or local authority having jurisdiction.

EXTENSION CORDS
Plug heater’s power cord into approved, grounded,
three-wire extension cord. Extension cord must be
at least six feet (1.8 meters) long.
Extension Cord Size Requirement
Operation
6 to 10 feet (1.8 to 3 meters) long, use 18 AWG
2
(0.75 mm
) rated cord
11 to 100 feet (3.3 to 30.5 meters) long, use 16 A WG

VENTILATION
WARNING: Provide a fresh, outside air
opening of at least three square feet (2,800
square cm) for each 100,000 Btu/Hr (29.3
kW) rating. Provide extra fresh air if more
heaters are being used. The minimum
ventilation requirements must be followed
to avoid risks associated with carbon
monoxide poisoning. Make certain these
requirements are met prior to operating
heater.
Example:
A 165,000 Btu/Hr (48.35 kW) heater
requires one of the following:
• a two-car garage door (16 feet [4.88 m] wide
opening) raised four inches (10.16 cm)
• a single-car garage door (9 feet [2.74 m] wide
opening) raised seven inches (17.78 cm)

used, include equivalent ventilating area.
• Provide adequate clearance from people,
animals, and combustible materials - 8 feet
(2.4 m) from heater outlet; 6 feet (1.8 m)
from top; 4 feet (1.2 m) from sides.
