Operating Environment and
Maintenance Kits
The following kits are offered to keep the unit running at
its peak:
• Battery Heater Kit
• Recommended for operating environments with
temperatures below 32 °F (0 °C).
• Engine Block Heater Kit
• Recommended for operating environments with
temperatures below 0 °F (–18 °C).
• Scheduled Maintenance Kit
• Kit includes the recommended parts to maintain
the generator.
Schedule for regular maintenance intervals.
For additional information, or to order any of these kits,
contact an IASD or customer service representative.
Coolant Water Treatment
DANGER
Risk of Poisoning. Do not allow coolant to contact skin or
eyes. If coolant is consumed, seek medical attention im-
mediately. Failure to do so will result in death or serious
injury.
WARNING
Risk of burns. Do not open coolant system
until engine has completely cooled. Doing so
could result in serious injury.
CAUTION
Engine damage. Use approved coolant only. Failure to
do so could result in equipment damage.

Equipment damage. Do not use any chromate base rust
inhibitor with ethylene glycol base antifreeze, boosters,
or additives. Doing so will cause overheating.
Use of incorrect coolants can damage the engine and
cooling system. Use demineralized water or distilled
50
water for best results. Hard water causes scale deposits,
122
which reduces cooling efficiency and raises internal tem-
016059
peratures, possibly leading to engine damage. Use an
anti-corrosive to prevent corrosion in summer and anti-
freeze to prevent freezing in winter.
Dilute the anti-freeze based on a theoretical temperature
that is 9–18 °F (5–10 °C) below the lowest temperature
expected in the area. A ratio of 40–60% is most common
range.

NOTE: Use only Peak Fleet-Charge
col type coolant (available from any IASD).
IMPORTANT NOTE: Do not use propylene glycol type
coolant. Using the wrong coolant, mixing different
types of coolant, or even mixing different brands of
the correct type of coolant, can produce unsatisfac-
tory results, possibly leading to engine or cooling
system damage.
Fuel Requirements
This unit may be equipped with one of the following fuel
systems:
• Liquid Propane (LP) Vapor
• Natural Gas (NG)
Recommended fuels must have a BTU content of at least
91,452 BTU/US gal (25.5 MJ/L) for LP, or 1,036 BTU/ft
(38.6 MJ/m 3 ) for NG. If converting to LP from NG, a mini-
mum LP tank size of 250 gal (946 L) is recommended.
See the installation manual for complete details and
procedures.
Fuel System Configuration
The engine is factory configured to use either NG or LP
vapor. It is not field convertible between natural gas and
propane. Fuel mixing and ignition timing are only set at
the factory for the specific fuel.
