H. Exhaust Kit Installation
H.1 Spark Arrester
The Generator exhaust is equipped with a U.S. Forest Service approved spark-arrest
muffler. NPS generators are designed with a spark-arrest feature in order to meet U.S
Forest Service requirements. Spark arrestors should not be removed. Removal of, or
failure to install the spark arrestor, may be a violation of state law.
Tampering with, or making any unapproved modification of the exhaust system voids
NPS' Limited Warranty and places liability on the party making the modification. NPS
does not accept liability for any damage or injury resulting from an unapproved.
modification. See Exhibits 6, 7, 8 and 9.
H.2 DANGER! CO POISONING and ENGINE EXHAUST INHILATION
Gasoline-powered engines and tools present a serious health hazard. They produce high
concentrations of CO and other toxic substances in their associated fumes and vapors
which, when inhaled in high concentrations, may result in death or extreme bodily injury
to the installer. CO is a poisonous, toxic, odorless, colorless and non-irritating gas, which
is given off whenever fuel or other carbon-based materials are burned.
CO can rapidly accumulate (even in areas appearing to be well ventilated), and can
overcome exposed persons without warning. Unsafe levels of CO may exist near running
gas generators or near air outflow, venting or exhaust from Generator. CO is a poisonous
gas that can cause illness, permanent neurological damage and death. Breathing CO may
produce headache, dizziness, vomiting and nausea and, in high concentrations,
unconsciousness or death. Exposure to CO at moderate to high levels, over long periods
of time, as also been linked with increased risk of heart disease.
Prior to proceeding with Generator installation:
• Ensure installation area is equipped with a working CO/smoke detector.
o
Verify detector is functioning properly prior to commencing with
Generator installation.
• Ensure RV is equipped with working CO/smoke detector.
o
Verify detector is functioning properly prior to spending time in RV
while Generator is operating.
