Massachusetts And New York City, NY Re- quirements

These appliances are approved for installation in the following USA locations listed in the following:

Massachusetts:

These fireplaces are approved for installation in the US state of Massachusetts if the following additional requirements are met-

•Installation and repair must be done by a plumber or gas fitter licensed in the Common- wealth of Massachusetts.

•The flexible gas line connector used shall not exceed 36 inches (92 centimeters) in length.

•The individual manual shut-off must be a T-handle type valve.

Massachusetts Horizontal Vent Requirements

In the Commonwealth of Massachusetts, hori- zontal terminations installed less than seven

(7)feet above the finished grade must comply with the following additional requirements:

•A hard wired carbon monoxide detector with an alarm and battery back-up must be installed on the floor level where the gas fireplace is installed. The carbon monoxide detector must comply with NFPA 720, be ANSI/UL 2034 listed and be ISA certified.

•A metal or plastic identification plate must be permanently mounted to the exterior of the building at a minimum height of eight (8) feet above grade and be directly in line with the horizontal termination. The sign must read, in print size no less than one-half (1/2) inch in size, GAS VENT DIRECTLY BELOW. KEEP CLEAR OF ALL OBSTRUCTIONS.

These fireplaces are approved for installation in New York City in the US state of New York.

Cold Climate Insulation

For cold climate installations, seal all cracks around the appliance with noncombustible material and wherever cold air could enter the room. It is especially important to insulate outside chase cavity between studs and under floor on which the appliance rests, if floor is above ground level. Gas line holes and other openings should be caulked or stuffed with unfaced fiberglass insulation. If the fireplace is being installed on a cement slab, in cold climates, a sheet of plywood or other raised platform can be placed underneath to prevent conducting cold up into the room. It also helps to sheetrock inside surfaces and tape for maximum air tightness and caulk firestops.

Location

In selecting the location, the aesthetic and func- tional use of the appliance are primary concerns. However, vent system routing to the exterior and access to the fuel supply are also important. Consideration should be given to traffic ways, furniture, draperies, etc., due to elevated surface temperatures (Figure 4). The location should also be free of electrical, plumbing or other heating/air conditioning ducting.

These direct vent appliances are uniquely suited for installations requiring a utility shelf positioned directly above the fireplace. Utility shelves like these are commonly used for locat- ing television sets and decorative plants. Be aware that this is a heat producing appliance. Objects placed above the unit are exposed to elevated temperatures.

To provide for the lowest possible shelf surface use the alternate rear vent outlet with attached venting routed in a way to minimize obstructions to the use of the space above the appliance. Do not insulate the space between the appliance and the area above it. See Figure 9. The mini- mum height from the base of the appliance to the underside of combustible materials used to construct a utility shelf in this fashion is shown in the Table in Figure 9.

The appliance should be mounted on a fully supported base extending the full width and depth of the unit. The appliance may be located on or near conventional construction materials. However, if installed on combustible materials, such as carpeting, vinyl tile, etc., a metal or wood barrier covering the entire bottom surface must be used.
