GAS PRESSURE SUPERVISION

The Commonwealth of Massachusetts requires listed high

and low gas pressure switches (manual reset) for any model

with a maximum firing input greater than 1,000,000 Btu/Hr in

accordance with 248 CMR 7.04(11)(d).

A gas pressure regulator (field supplied) is required in the

gas train ahead of the heater, for heaters having input rates

greater than 1,000,000 Btu/Hr, in accordance with 248 CMR

7.04 Figure 3B requirements.

The Commonwealth of Massachusetts requires compliance

with regulation 248 CMR 4.00 and 5.00 for installation of

(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 installation 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 horizontal vent-

ed 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; provided, 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 min-

imum 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 the installation unless, upon inspection, the inspec-

tor observes carbon monoxide detectors and signage

installed in accordance with the provisions of 248 CMR

5.08(2)(a)1 through 4.
