EXHAUST SPARK ARRESTERS
Exhaust spark arresters are necessary when
operating in some parks and camps. Two basic types
are used in the recreation vehicle industry. One is a
spin-out type spark arrester, the other is a screen type
spark arrester. All require periodic clean-out (every
50 to 100 operating hours) to maintain maximum
efficiency.
Spin-Out Type Spark Arrester
This type removes carbon particles by centrifugal
force, catching the particles in a holding chamber.
Removing a pipe plug from the arrester and operating
the electric set (at a convenient time and place) cleans
out the deposits. It is important to note this arrester
does not plug up when the holding chamber is full and
does not cause harmful, high exhaust back pressure.
When full, particles pass through the arrester.
Screen Type Spark Arrester
This arrester has a screen which traps carbon par¬
ticles as they pass through. The screen is removed,
cleaned or replaced after it has filled. A disadvantage
of this type is the screen plugs as it collects the
particles and gradually increases exhaust back
pressure. Back pressure causes a loss of engine
power and can cause burned or damaged valves if
pressure is high enough. It is very important this type
be cleaned as recommended.
IMPORTANT: Certain states (particularly California) have state
ordinances pertaining to the type and usage of exhaust
muftler/spark arresters on internal combustion engines or engine
driven equipment when used in a recreational vehicle such as
electric generating sets. Be sure your installation meets all Federal,
State and local codes pertaining to your unit. Failure to provide and
maintain a spark arrester may be in violation of the law.
warning!
EXHAUST GAS IS DEADLY!
Exhaust gases contain carbon monoxide, an odorless and colorless gas. Carbon
monoxide is poisonous and can cause unconsciousness and death. Symptoms of
carbon monoxide poisoning can include:
• Dizziness • Throbbing in Temples
• Nausea • Muscular Twitching
• Headache • Vomiting
• Weakness and Sleepiness • inability to Think Coherently
IF YOU OR ANYONE ELSE EXPERIENCE ANY OF THESE SYMPTOMS, GET OUT
INTO THE FRESH AIR IMMEDIATELY. If symptoms persist, seek medical atten¬
tion. Shut down the unit and do not operate until it has been inspected and
repaired.
Never sleep in vehicle with the generator set running unless the vehicle interior is
equipped with an operating carbon monoxide detector. Protection against carbon
monoxide inhalation also includes proper exhaust system installation and visual
and audible inspection of the complete exhaust system at the start of each
generator set operation.
