Revise  NFPA-54  section  10.8.3  to  add  the  following 

requirements:

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 the 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,  horizontally  vented,  gas-fueled  equipment,  the 

installing  plumber  or  gas  fitter  shall  observe  that  a 

hard-wired  carbon  monoxide  detector  with  an  alarm 

and battery backup is installed on the floor level where 

the gas equipment is to be installed. In addition, the 

installing  plumber  or  gas  fitter  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, horizontally 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  backup  may  be 

installed on the next adjacent floor level.

b.  In the event that the requirements of this 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 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  the  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.

EXEMPTIONS: The following equipment is exempt 

from 24 CMR 5.08(2)(a) 1 through 4:

Not Required to Be Vented” in the most current edition 

of NFPA 54 as adopted by the Board; and

2.  Product Approved side wall, horizontally vented, gas-

fueled  equipment  installed  in  a  room  or  structure 

separate from the dwelling, building or structure used 

in whole or in part for residential purposes.

MANUFACTURER REQUIREMENTS - GAS EQUIPMENT 

VENTING SYSTEM PROVIDED. 

When  the  manufacturer  of  Product  Approved  side  wall, 

horizontally  vented,  gas-fueled  equipment  provides  a

with  the  equipment,  the  instructions  provided  by  the 

manufacturer  for  installation  of  the  equipment  and  the 

venting system shall include:

1.  Detailed instructions for the installation of the venting 

system design or the venting system components: and 

2.  A complete parts list for the venting system design or 

venting system.

MANUFACTURER REQUIREMENTS - GAS EQUIPMENT 

VENTING SYSTEM NOT PROVIDED. 

When  the  manufacturer  of  Product  Approved  sidewall, 

horizontally  vented,  gas-fueled  equipment  does  not
