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.

• 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.
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.
