GENERAL INFORMATION

INSTALLATION REQUIREMENTS FOR THE COMMONWEALTH OF MASSACHUSETTS

For al l side w all terminated, hor izontally vented power vent, direct vent, and power direct vent gas fueled w ater heat ers installed i n ev ery dwelling, building or structure used in w hole or in p art f or residential pur poses, including t hose ow ned 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:

INSTALLATION OF CARBON MONOXIDE DETECTORS

At the time of installation of the side wall horizontal vented gas fueled equipment, the installing plumber or gas fitter shall observe that a hard wired carbon monoxide detector with an alarm and battery back- up is in stalled on t he f loor le vel wh ere t he g as equipment is t o b e i nstalled. In add ition, t he installing plumber or gas fitter shall observe that a battery operated or har d w ired carbon monoxide detector w ith an al arm i s i nstalled on eac h additional level of the dwelling, building or structure served by the sidewall horizontal vented gas fueled equipment. It s hall b e the re sponsibility o f the property owner to secure the services of qualified licensed pr ofessionals for the i nstallation of har d wired carbon monoxide detectors. In the event that the s ide wall hor izontally v ented 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 f loor l evel. I n t he e vent t hat the requirements of this subdivision can not be met at the t ime of c ompletion of i nstallation, t he ow ner shall have a period of thirty (30) days to comply with the above requirements p rovided that during said thirty ( 30) day p eriod, a bat tery op erated carbon monoxide detector with an alarm shall be installed

APPROVED CARBON MONOXIDE DETECTORS Each carbon monoxide de tector as r equired in accordance with the above provisions shall comply with NFPA 720 and be ANSI/UL 2034 listed and CSA certified.

SIGNAGE

A m etal or p lastic i dentification plate s hall b e 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.”
