to secure the services of qualified licensed professionals for the 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 detector with alarm and battery back-up may
be installed on the next adjacent floor level.
b. In the event that the requirements of this subdivision can not be met at the time of completion
of installation, the owner shall have a period of thirty (30) days to comply with the above

carbon monoxide detector with an alarm shall be installed.
2. APPROVED CARBON MONOXIDE DETECTORS. Each carbon monoxide detector as required in
accordance with the above provisions 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) ft. above grade directly in line with the exhaust vent
terminal for the horizontally vented gas fueled heating appliance or equipment. The sign shall read,
in print size 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

monoxide detectors and signage installed in accordance with the provisions of 248 CMR 5.08(2)(a)1
through 4.
