NEW YORK CITY, NY AND MASSACHUSETTS REQUIREMENTS

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

Massachusetts -

Installation of 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 Commonwealth 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.

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

Massachusetts Horizontal Vent Requirements

In the Commonwealth of Massachusetts, horizontal 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 IAS 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.”

New York City, New York

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 functional 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 (see 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 locating television sets and decorative plants. Be aware that this is a heat producing appliance. Objects placed above the unit are exposed to elevated temperatures.

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

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 minimum 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.

Step 4. (Page 25) Field Wiring

a.Millivolt Appliances – Install the operating control switch (not factory provided) and bring in electrical service line for forced air circulating blower (optional equipment).

b.Electronic Appliances – Field wire and install operating control switch.

Step 5. (Page 25) Install blower kit (optional equipment).

Step 6. (Page 26) Make connection to gas supply.

Step 7. (Page 27) Checkout appliance operation. Step 8. (Page 28) Install the logs, decorative

volcanic stone and glowing embers.

Step 9. (Page 30) Install glass door frame assembly.

Step10.(Page30) Adjustburnertoensureproper flame appearance.

Step 11. (Page 31) Install the hoods.

Step 1. Framing

Frame these appliances as illustrated in Figure 14 on Page 11, unless the appliance is to be installed in a corner. See Figure 15 on Page 12 for corner framing installations. All framing details must allow for a minimum clearance to combustible framing members as shown in

Table 8 on Page 9.

If the appliance is to be elevated above floor level, a solid continuous platform must be constructed.

Headers may be in direct contact with the appliance top spacers but must not be supported by them or notched to fit around them. All construction above the appliance must be self supporting. DO NOT use the appliance for structural support.

Note: The nailing flanges, combustible members
and screw heads located in areas directly adjacent
to the nailing flanges, are EXEMPT from the 1/2”
clearance to combustible requirements for the
firebox outer wrapper. Combustible framing may be
in direct contact with the nailing flanges and may
be located closer than 1/2” from screw heads and
the firebox wrapper in areas adjacent to the nailing
flanges. Frame the opening to the exact dimensions
specified in the framing details of this manual.

Step 2. Routing Gas Line

Route a 1/2" (13 mm) gas line along the inside of the right side framing as shown in Tables. Gas lines must be routed, constructed and made of materials that are in strict accordance with local codes and regulations. All appliances are factory-equipped with a flexible gas line connector and 1/2 inch shutoff valve. (See Step 6 on Page 26).
