6 Owner’s Manual for Flameless Air Heater

General Information

Emissions Information

For emissions information, see the OEM manual.

Engine Oil Recommendations

NOTE: Certain brands/types of oil can be used regard-

less of specified API or ACEA grade.

Figure 2-1. Engine Oil Viscosity Chart for 550F

NOTE: For temperatures below -13° F (-25° C), use SAE

5W30.

Engine capacity: 9.8-12.9 qt (9.3-12.1 L).

For more information, see the engine manual.

Coolant Recommendation

Use of improper coolants can damage the engine cooling

system. Use demineralized water or distilled water for

best results. Hard water causes scale deposits, which

reduces cooling efficiency and raises internal

temperatures, possibly leading to engine damage.

Where the atmospheric temperature falls below freezing

point, the cooling system should be drained after engine

operation, but to eliminate the need for repeated draining

and refilling, the use of antifreeze solution is highly

recommended. Follow these antifreeze/water guidelines:

• A 50/50 ethylene glycol base antifreeze/water mix,

which provides protection to -34°F (-37°C), is rec-

ommended for use in this engine.

• Never exceed a 60/40 antifreeze/water mix, which

provides protection to about -58°F (-50°C).

• Any coolant must be nitrite free and meet the per-

formance standards of ASTM D6210.

System capacity (engine only): 4.5 qt (4.3 L).

For more information, see the engine manual.

Fuel System

The engine is designed to use either Number 1-D or

Number 2-D diesel fuel.

• For better fuel economy, use Number 2-D diesel

fuel whenever possible.

• At temperatures below 20° F (-7° C), use Number

1-D or a winterized blend (check with the service

station operator to ensure you get the properly

blended fuel).

The following are required for the diesel fuel:

• Must be free from dust particles

• Must have adequate viscosity

• Must have high cetane value

• Must have high fluidity at low temperature

• Must have low or ultra-low sulfur content

EPA requirement; varies by geographic location

• Must have little residual carbon

If fuel other than what is specified is used, engine

function will be lowered. For more information, see the

engine manual.

Fuel tank capacity: 159 gal (602 L).
