Massachusetts And New York City, NY Requirements

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 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.

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 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.

New York City, NY:

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.

Figure 4 - Typical Locations

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 (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.

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.

Detailed Installation Steps

Theapplianceisshippedwithallgascontrolsand components installed and pre-wired. Remove the shipping carton, exposing the front glass door. Remove the top and bottom louvered control panel per instructions on Page 25 (see

Control Compartment Access / Louver Panel Instructions). Remove the cardboard from underneath the pressure relief plates (in area behind top louver panel, See Figure 11). Open the two latches (located under the firebox floor) securing the glass door. Remove the door by tilting it outward at the bottom and lifting it up. Set the door aside protecting it from inadvertent damage. See Figure 57 on Page 29.

TYPICAL INSTALLATION SEQUENCE

The typical sequence of installation follows, however, each installation is unique resulting in variations to those described.

See the Page numbers references in the following steps for detailed procedures.

Step 1. (Page 8) Construct the appliance framing. Position the appliance within the framing and secure with nailing brackets.

Step 2. (Page 8) Route gas supply line to appliance location.

Step 3. (Page 11) Install the vent system and exterior termination.

Step 4. (Page 23) 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 23) Install blower kit (optional equipment).

Step 6. (Page 24) Make connection to gas supply.

Step 7. (Page 25) Install the logs, decorative volcanic stone and glowing embers.

Step 8. (Page 26) Checkout appliance operation.

Step 9. (Page 29) Install glass door frame assembly.

Step 10. (Page 29) Adjust burner to ensure proper flame appearance.

Step 11. (Page 30) Install the hoods.

Step 1. Framing

Frame these appliances as illustrated in Figures 14 & 15 on Pages 9 & 10 (Figure 15 applies to corner framing installations only). All framing details must allow for a minimum clearance to combustible framing members as shown in

Table 8 on Page 7.

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.

The fireplace should be secured to the side framing members using the unit's nailing flanges - one top and bottom on each side of the fireplace front. See Figure 12. Use 8d nails or their equivalent.

To The Framing

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.

Figure 12

Step 2. Routing Gas Line

Route a 1/2" (13 mm) gas line along the inside of the right side framing as shown in Figure 13. 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 24 ).

Proper Sizing of Gas Line

Properly size and route the gas supply line from the supply regulator to the area where the appliance is to be installed per requirements outlined in the National Fuel Gas Code, NFPA 54 - latest edition (USA) or B149 - latest edition (Canada).

Never use galvanized or plastic pipe. Refer to Table 9 for proper sizing of the gas supply line, if black iron pipe is being used. Gas lines must be routed, constructed and made of materials that are in strict accordance with local codes and regulations. We recommend that a qualified individual such as a plumber or gas fitter be hired to correctly size and route the gas supply line to the appliance. Installing a gas supply line from the fuel supply to the appliance involves numerous considerations of materials, protection, sizing, locations, controls, pressure, sediment, and more. Certainly no one unfamiliar and unqualified should attempt sizing or installing gas piping.

Notes:

All appliances are factory-equipped with a flexible gas line connector and 1/2 inch shutoff valve (see Figure 48 on Page 24 ).

See Massachusetts Requirements on Page 4 for additional requirements for installations in the state of Massachusetts in the USA.

The gas supply line should Not be connected to the appliance until Step 6 (Page 24 ).

A pipe joint compound rated for gas should be used on the threaded joints. Ensure propane resistant compounds are used in propane applications. Be very careful that the pipe compound does not get inside the pipe.

It is recommended to install a sediment trap in the supply line as close as possible to the appliance (see Figure 48 ). Appliances using Propane should have a sediment trap at the base of the tank.

Check with local building official for local code requirements(i.e.arebelowgradepenetrations of the gas line allowed?, etc).

IMPORTANT: If propane is used, be aware that if tank size is too small (i.e. under 100-lbs, if this is the only gas appliance in the dwelling. Ref. NPFA 58), there may be loss of pressure, resulting in insufficient fuel delivery (which can result in sooting, severe delayed ignition or other malfunctions). Any damage resulting from an improper installation, such as this, is not covered under the limited warranty.

Step 3. Install the Vent System

General Information

These instructions should be used as a guideline and do not supersede local codes in any way. Install vent according to local codes, these instructions, the current National Fuel Gas Code (ANSI-Z223.1) in the USA or the current standards of CAN/CGA-B149.1 and -B149.2 in Canada.

Useonlyapprovedventingcomponents. See

Approved Vent Components on Page 2.

These fireplaces must be vented directly to the outside.

The vent system may not service multiple appliances, and must never be connected to a flue serving a solid fuel burning appliance. The vent pipe is tested to be run inside an enclosing wall (such as a chase). There is no requirement for inspection openings in the enclosing wall at any of the joints in the vent pipe.

Preparing the Appliance Vent Collar on LMDV-

3530/4035 Series (Combined Top and Rear

Vent) Models.

Each of the unit's two vent collars are sealed with a cover plate and a seal plate and gasket. The cover, and seal plate and gasket must be removed from the vent collar being used. Refer to Figure 16 for top vent usage and Figure 17 for rear, and the following steps to prepare the appropriate collar for use.

From the vent collar being used, remove the four screws securing the vent seal plate and gasket. Remove and discard the seal plate and gasket.

When the top vent collar is being used, from inside the firebox, loosen the two screws in the keyhole slots of the cover plate and remove the remaining two cover plate securing screws. Remove and discard the cover plate. Reinstall and securely tighten all four screws.

WARNING

Failure to reinstall and securely tighten cover plate screws could result in leakage of flue products into the living space. Vent cover plate and vent seal plate must remain securely installed on unused vent collar. Failure to do so could result in leakage of flue products into living space.

When the rear vent collar is being used, from inside the firebox, remove the two screws securing the lintel to the rear wall of the firebox, then remove the lintel. Remove the four cover plate securing screws.

Remove and discard the cover plate. Reinstall and securely tighten all four cover plate screws. Re-secure the lintel to the rear wall of the firebox.
