Operator Manual for Gasoline Generators
▪ Aim the probe downwards with the opening pointed in the direction of
the water flow and just out of the flow.
▪ Position the analyzer as high as possible with the tubing leading to the
probe running continuously downhill.
▪ Observe the usually translucent tubing between the probe and the
analyzer and be sure no water is ingested. If any water is ingested into
the analyzer, it must be repaired and recalibrated or replaced.
▪ When measuring CO at the exhaust outlet be aware of the ambient CO
level by also measuring CO away from and upwind of the exhaust
outlet, especially in marinas. The CO level at the exhaust outlet will be
influenced upwards by the ambient level.
▪ Whenever taking the time to verify proper CO concentration from the
exhaust with a CO analyzer, always use the analyzer to sniff around the
engine looking for CO from exhaust leaks. Pay close attention to the
connection of the cylinder head to the exhaust manifold, the exhaust
manifold to the water-injected exhaust elbow, and all subsequent
downstream exhaust components and hoses.
▪ Exhaust gas that has not yet passed through the catalyst is raw,
untreated, and very high in CO content.
▪ Analyzers usually require periodic calibration. Follow the instructions
that come with the analyzer very carefully regarding calibration.
▪ The following manufacturers offer CO analyzers: Extech, TIF, Testo, TSI,
Bacharach, Fluke, Monoxor, Fyrite, Zellweger Analytics, Industrial
Scientific, GFG, TPI, Teledyne, and others.
▪ Westerbeke recommends analyzers with a probe connected to the
analyzer by a length of transparent tubing. They are slightly more
expensive than those with the sensor built-in to one end of the analyzer,
but they allow you to sample the exhaust coming out of the boat
exhaust outlet.
California Exhaust Emissions Standards
This generator meets the requirements of the California Exhaust Emissions
Standards as stated on the nameplate. California users of this generator
