Placement of Standby Generator to

REDUCE THE RISK OF FIRE

Requirements:
NFPA 37 2010, section 4. 1. 4, Engines Located
Outdoors. Engines, and their weatherproof housings
if provided, that are installed outdoors shall be located
at least 1.5m (5 ft) 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 above 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.
