HELPFUL HINTS
If fl ammable gases are lighter than air, the inlet connection
to each enclosure must enter near a bottom corner. The
outlet connection, for an optional enclosure protection
vent or piping to an adjacent protected enclosure, must
exit near an extreme opposite top corner.
If fl ammable gases are heavier than air, inlet and outlet
connections must be reversed.
In all cases, the most prevalent gas must determine the
location of inlet and outlet connections.
