bottom of the vent terminal and the air intake is installed
below four feet above grade the following requirements
must be satisfied:
a.) A carbon monoxide (CO) detector and alarm shall be
placed on each floor level where there are bedrooms.
The detector shall comply with NFPA 720 (2005
Edition) and be mounted in the living area outside
the bedroom(s).
b.) A (CO) detector shall be located in the room that
houses the appliance or equipment and shall:
• Be powered by the same electrical circuit as the
appliance or equipment. Only one service switch

• Have battery back-up power;
• Meet ANSI/UL 2034 Standards and comply with
NFPA 720 (2005 Edition); and Approved and listed
by a Nationally Recognized Testing Laboratory as
recognized under 527 CMR.
c.) A Product-approved vent terminal must be used, and
if applicable, a product-approved air intake must be
used. Installation shall be in strict compliance with the
manufacturer’s instructions. A copy of the installation
instructions shall remain with the appliance or
equipment at the completion of the installation.
d.) A metal or plastic identification plate shall be mounted
at the exterior of the building, four feet directly above
the location of vent terminal. The plate shall be of
sufficient size, easily read from a distance of eight
feet away, and read “Gas Vent Directly Below”.
2. For direct-vent appliances, mechanical-vent heating
appliances or domestic hot water equipment where the
bottom of the vent terminal and the air intake is installed

Combustion Air Quality
CAUTION:
Combustion air must not be drawn from a
corrosive atmosphere.
To maximize heat exchanger life, the combustion air must be
free of chemicals that can form corrosive acidic compounds
in the combustion gases. The recommended source of
combustion air is to use outdoor air. However, the use of
indoor air in most applications is acceptable except as listed:
• If the furnace is installed in a confined space, it is required
that the necessary combustion air come from the outdoors
by way of attic, crawl space, air duct, or direct opening.
For installations in confined spaces, see
page 7.
• Installations in these locations may require outdoor air for
combustion, due to chemical exposures:
Commercial buildings
Buildings with indoor pools
Furnaces installed in laundry rooms
Furnaces installed in hobby or craft rooms
Furnaces installed near chemical storage areas
