1. Installation of Carbon Monoxide Detectors
At the time of installation of the side-wall vented
gas fueled unit, the installing plumber or gasfitter
shall observe that a hard wired carbon monoxide
detector with an alarm battery back-up is installed on
the floor level where the gas unit is to be installed.
In addition, the installing plumber or gasfitter shall

additional level of the dwelling, building or structure
served by the side-wall horizontally vented gas fueled
equipment. It shall be the responsibility of the property
owner to secure the services of qualified licensed
professionals for installation of hard wired carbon
monoxide detectors.
a. 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 with alarm and
battery back-up may be installed on the next adjacent
floor level.
b. In the event that the requirements of the subdivision
cannot be met at the time of completion of installation,
the owner shall have a period of thirty (30) days
to comply with the above requirements, provided,
however, that during said thirty (30) day period, a
battery operated carbon monoxide detector with an
alarm be installed.
2. Approved Carbon Monoxide Detectors
Each carbon monoxide detector shall comply with
NFPA 720 and be ANSI/UL 2034 listed and IAS
certified.
3. Signage
A metal or plastic identification plate shall be
permanently mounted to the exterior of the building
at a minimum height of eight (8) feet above grade
directly in line with the exhaust vent terminal for
horizontally vented gas fueled heating unit or
equipment. The sign shall read, in print no less than
one-half (1/2) inch in size: "GAS VENT DIRECTLY
BELOW, KEEP CLEAR OF ALL OBSTRUCTIONS."
4. Inspection
The state or local gas inspector of the side-wall
horizontally vented gas fueled unit shall not approve
the installation unless, upon inspection, the inspector
