alarm and battery back-up must be installed on
the floor level where the gas equipment is to be
installed AND on each additional level of the
dwelling, building or structure served by the side
wall horizontal vented gas fueled equipment.

•

In the event that the side wall horizontally vented
gas fueled equipment is installed in a crawl space
or an attic, the hard wired carbon monoxide
detector with alarm and battery back-up may be
installed on the next adjacent floor level.

Detector(s) must be installed by qualified licensed
professionals.
