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:

1.The equipment listed in Chapter 10 entitled “Equipment 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 venting system design or venting system components 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 provide the parts for venting the flue gases, but identifies “special venting systems,” the following requirements shall be satisfied by the manufacturer:

1.The referenced “special venting system” instructions shall be included with the appliance or equipment installation instructions; and

2.The “special venting systems” shall be Product Approved by the Board, and the instructions for that system shall include a parts list and detailed installation instructions.

A copy of all installation instructions for all Product Approved side wall, horizontally vented, gas fueled equipment, all venting instructions, all parts lists for venting instructions, and/or all venting design instructions shall remain with the appliance or equipment at the completion of the installation.
