Cabinet Preparation
In preparation for mounting a chimney, remove 1/4-20 fasteners from the Relief
vent on the top of the MV enclosure. Leave the four corner fasteners in place
(see

The chimneys are designed to fit over the fastener heads at the (4) corners of the
Relief vent. The corner fasteners are required to secure the Relief vent during
installation.
