Owner’s Manual for Indirect Fired Heater

General Information

Emissions Information

For emissions information, see the diesel engine OEM
manual.

Engine Oil Recommendations

Change oil and oil filter at least once every 12 months,
even if the hours of operation are fewer than the other-
wise recommended service interval. See the diesel
engine OEM manual for recommended oil types.
For more information, see the engine manual.

Coolant Recommendation

Use demineralized or distilled water for best results. Hard
water causes scale deposits, which reduces cooling effi-
ciency and raises internal temperatures, possibly leading
to engine damage. 
Use a Long Life Coolant Antifreeze or Extended Life
Coolant that meets or exceeds these specifications:

Isuzu Part Number 8-12346-290-0

ASTM D4985

See the engine manual for recommended coolants.
Test coolant yearly, or every 1000 hours, whichever
comes first.
For more information, see the engine manual.

Fuel System

The heater is designed to operate with diesel fuel. 

IMPORTANT NOTE: Comply with all laws regulating
the storage and handling of fuels.

Follow these guidelines:

Use only ultra-low-sulfur diesel (ULSD) fuel.

When temperatures are at or below freezing, use
No. 1D diesel fuel.

When temperatures are above freezing, use No.
2D diesel fuel.

In some areas of the country, climatized fuel—a
mixture of 1D and 2D—may also be used.

For more information, see the engine manual.

Cart Towing Guidelines

IMPORTANT NOTE: Do not exceed 15 mph

 (24 k

m/

h)

.

The front axle is steered by a tow bar with a pintle ring

 

hitch. It is equipped with a mechanical parking brake

 

activated by raising the tow bar to the locked position.

NOTE: 

See the tow vehicle manual for coupling instruc-

tions.

Driving a vehicle with a cart in tow is vastly different than

 

driving the same vehicle without a cart in tow. Consider

 

the following:

It takes longer to get up to speed.

More room is need to turn.

More distance is needed to stop.

The driver is responsible for keeping the vehicle
and cart in control, and for all damage caused if
control is lost.

(000149)

DANGER

Risk of poisoning. Do not use mouth to siphon 
coolant. Doing so will result in death or serious 
injury.

CAUTION

(000323)

Engine damage. Use approved coolant only. 
Failure to do so could result in equipment damage.

(000168)

DANGER

Explosion and Fire. Fuel and vapors are 
extremely flammable and explosive. Keep fire 
and spark away. Failure to do so will result 
in death or serious injury. 

(000204)

DANGER

Explosion and Fire. Do not overfill fuel tank. 
Overfilling may cause fuel to leak and ignite 
or explode, resulting in death or serious injury.

WARNING

Control loss. Trailer must be securely coupled to the 
hitch. An incorrectly coupled trailer could result in loss 
of control, death, or serious injury.

(000360)

WARNING

Property or Equipment Damage. Tighten wheel lug 
nuts every 30 days to factory specifications. Failure to 
do so could result in death, serious injury, or property 
or equipment damage.
