IMPORTANT: The Commonwealth of Massachusetts requires compliance with regulation 248 CMR 4.00
and 5.00 for installation of side-wall vented gas appliances as follows:
(a) For all side wall horizontally vented gas fueled equipment installed in every dwelling, building or
structure used in whole or in part for residential purposes, including those owned or operated by the
Commonwealth and where the side wall exhaust vent termination is less than seven (7) feet above
finished grade in the area of the venting, including but not limited to decks and porches, the following
requirements shall be satisfied:
1. INSTALLATION OF CARBON MONOXIDE DETECTORS. At the time of installment of the
side wall horizontal vented gas fueled equipment, the installing plumber or gasfitter shall observe
that a hard wired carbon monoxide detector with an alarm and battery back-up is installed on
the floor level where the gas equipment is to be installed. In addition, the installing plumber or
gasfitter shall observe that a battery operated or hard wired carbon monoxide detector with an
alarm is installed on each additional level of the dwelling, building or structure served by the side
wall vented gas fueled equipment. It shall be the responsibility of the property owner 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
requirements; however, that during said thirty (30) day period, a battery operated 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) feet 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
equipment shall not approve installation unless, upon inspection, the inspector observes
carbon monoxide detectors and signage installed in accordance with the provisions of 248 CMR
5.08(2)(a)1 through 4.
