A Non-Combustible material with Fire Resistant Rating of
1 hour or greater
B Home Standby Generator
C Engine Exhaust
D Combustible Material or Structure with a Fire
Resistance Rating of less than 1 hour.
E Any structure or material. DO NOT connect (A) and/or
(D) to (E).
Install generator outdoors in an area which will not
accumulate deadly exhaust gas. DO NOT install generator
where exhaust gas could accumulate and enter inside or be
drawn into a potentially occupied building. Ensure exhaust
gas is kept away from windows, doors, ventilation intakes
or other openings that can allow exhaust gas to collect in a
confined area. Prevailing winds and air currents should be
taken into consideration when positioning generator.

• Installtheunitinalocationwheresumppump
discharge, rain gutter down spouts, roof run-off,

• Installtheunitwhereairinletandoutletopenings
will not become obstructed by leaves, grass, snow,
etc. If prevailing winds will cause blowing or drifting,
you may need to construct a windbreak to protect
the unit.
• Installthegeneratorascloseaspossibletothe
transfer switch and fuel supply to reduce the length of
wiring, conduit, and piping.
Laws or local codes may regulate the distance to the
fuel supply.
