Placement of Standby Generator to REDUCE THE
RISK OF FIRE
The National Fire Protection Association (NFPA) standard
NFPA 37 establishes criteria for minimizing the hazard
of fire during the installation and operation of stationary
combustion engines. NFPA 37 limits the spacing of an
enclosed generator from openings in walls, structures, and
combustible materials outside the enclosure.
The placement requirements provided are based on
compliance to NFPA 37 2010 section 4.1.4.
WARNING Exhaust heat/gases could ignite combustibles
or structures resulting in death, serious injury and/
or property damage.
Exhaust outlet side of weatherproof enclosure must
have at least 5 ft. (1.5 m) minimum clearance from any
structure, shrubs, trees or any kind of vegetation.
Standby generator weatherproof enclosure must be at
least 5 ft. (1.5 m) from windows, doors, any wall opening,
shrubs or vegetation over 12 inches (30.5 cm) in height.
Standby generator weatherproof enclosure must have a
minimum of 5 ft. (1.5 m) overhead clearance from any
structure, overhang or trees.
DO NOT place weatherproof enclosure under a deck or
other type of structure that may confine airflow.
Use only flexible steel fuel line provided. Connect provided
fuel line to generator, DO NOT use with or substitute any
other flexible fuel line.
Smoke detector(s) MUST be installed and maintained
indoors according to the manufacturer's instructions/
recommendations. Carbon monoxide alarms cannot
detect smoke.
DO NOT place weatherproof enclosure in manner other
