Owner’s Manual for Indirect Fired Heater 11
General Information
Emissions
The United States Environmental Protection Agency (US
EPA) (and California Air Resources Board (CARB), for
engines/equipment certified to California standards)
requires that this engine/equipment complies with
exhaust and evaporative emissions standards. Locate
the emissions compliance decal on the engine to deter-
mine applicable standards. For emissions warranty infor-
mation, please reference the included emissions
warranty. It is important to follow the maintenance specifi-
cations in the manual to ensure that the engine complies
with the applicable emissions standards for the duration
of the product’s life.
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 applicable
engine manual for recommended oil types. Use only
approved 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.
See the engine manual for recommended coolants.
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 1,000 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, handling, and transporting of fuels.
Follow these guidelines:
• Use only ultra-low-sulfur diesel 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.
