Site Selection and Preparation

Mounting

Fixed Foundation

Use mounting holes in base frame to fasten unit to foun-
dation. Always use hardware of a suitable grade, size,
and style.

Connections

All electrical connections must have flexible sections to
isolate vibration if they connect to the unit base rails. Cor-
rectly support and secure all piping before installing flexi-
ble connection.

Combustible Floor and Roof Protection

Engines, and their weatherproof housings, if provided,
that are installed on roofs of structures shall be located at
least 5 ft (1.5 m) from openings in walls and at least 5 ft
(1.5 m) from structures having combustible walls. Per
NEC 110.26(E)(2), a minimum separation of 3 ft (0.91 m)
is permitted if the adjacent wall of the structure has a fire
resistance rating of at least 1 hour.
An oil containment system consisting of a curb or dike
having a capacity at least equal to the total capacity of
the lubricating oil system or the liquid fuel system, which-
ever is greater, shall be provided. This system shall also
comply with applicable requirements of NFPA 37, Chap-
ter 6.
The surface beneath the engine and beyond the engine
and the oil containment dike shall be noncombustible to a
minimum distance of 12 in (300 mm).
NOTE: Local building codes may have additional re-
quirements for placement of fuel storage tanks on top of
a roof or structure. Contact the local building code
department or fire marshal for code compliance before
placing generator on top of roof or structure.
