from openings in walls and at least 1.5 m (5 ft) from structures
having combustible walls. A minimum separation shall not be
required where either of the following conditions exist:
1. The adjacent wall of the structure has a fire resistance
rating of at least 1 hour.
2. The weatherproof enclosure is constructed
of noncombustible materials and it has been
demonstrated that a fire within the enclosure will not
ignite combustible materials outside the enclosure. *
Annex A Explanatory Material
A.4.1.4 (2) Means of demonstrating compliance are by means
of full-scale fire tests or by calculation procedures, such as
those given in NFPA 555,
Guide on Methods for Evaluating
Potential for Room Flashover.
To comply with condition 2, the weatherproof enclosure has
been constructed completely of non-combustible materials
and full-scale fire tests have been conducted to demonstrate
that a fire within the enclosure will not ignite combustible
materials outside the enclosure.
National Fire Protection Association (NFPA) Standard NFPA 37 Requirements and Testing
• Place the standby generator in a prepared location
that is flat and has provisions for water drainage.
• Install the standby generator in a location where
sump pump discharge, rain gutter down spouts, roof
run-off, landscape irrigation, or water sprinklers will
not flood the unit or spray the enclosure and enter
any air inlet or outlet openings.
• Install the standby generator where it will not affect or
obstruct any services (including covered, concealed
and underground), such as telephone, electric, fuel
(natural gas / LPG vapor), irrigation, air conditioning,
cable, septic, sewer, well and so forth.
• Install the standby generator where leaves, grass,
snow, etc will not obstruct air inlet and outlet
openings. If prevailing winds will cause blowing or
drifting, you may need to construct a windbreak to
protect the unit.
