10.APPENDIX B - EMISSION CONTROL SYSTEM
Your generator has an engine that has been approved by the California Air Resources Board. Other than the tune
up procedures specified in the maintenance section, no additional maintenance is required.
The emission control system has the following components:
1.
Fuel System: The fuel tank, cap, indicator and hoses are specially designed and constructed to not allow
fuel vapors to permeate and be released to the atmosphere.
2.
A carbon activated canister collects gasoline vapors from the fuel tank and returns them to the combustion
chamber for burning.
3.
A catalyst is built into the muffler to further treat the engine exhaust.
4.
A secondary air injection valve adds combustion air to ignite unburned fuel in the exhaust.
Contact your authorized POWERHOUSE® service center to obtain the correct replacement parts and service on
this system.
