6.4 Engine Exhaust
The exhaust system for this generator set is complete and was designed specifically
for this generator set. Do not modify or add to the exhaust system of this generator
set.
WARNING
Exhaust gas is deadly. Make sure that the exhaust system terminates away
from building vents, windows, doors, and sheltered spaces that may not
have ample fresh air ventilation.
WARNING
Engine discharge air and exhaust carry carbon monoxide gas (odorless and
invisible) which can cause asphyxiation and death. Never use engine
discharge air or exhaust for heating a room or enclosed space.
