AIR REQUIREMENTS CONT’D 
*Combustion Air Temperature: The output of the engine will decrease about 1% for 
 every 10°F of air temperature above 77°F or 25°C. 
IMPORTANT: Insulation and Sound Absorbing Material used inside of the generator compartment 
Must Not reduce the specified airspace clearance of one (1) inch or restrict the airflow around the 
generator. Such reduction in airspace may lead to an overheating situation and reduced generator 
performance. Also be sure the air inlet and outlet openings meet the specified requirements. Allow 
clearance inside the generator compartment for easy access when routine maintenance is required. 
WARNING: The generator compartment Must Be sealed to prevent hazardous fumes and vapors from 
entering the vehicles other compartments and interior spaces. Plugging holes and sealing all seams will 
greatly reduce this hazard. 
WARNING: Drip Proofing! When installing a generator, the area directly beneath the generator end of 
the unit must incorporate a non-flammable barrier. This barrier needs to be made of sufficient material 
able to withstand and prevent molten metal, burning insulation, flaming or sparking particles from 
penetrating the compartment floor or dripping beneath the compartment.
