Rest assured that every component of the Fireplace has been tested to ensure long-termdurability.

Product Overview

The Grand Meridian Fireplaces are designed as factory-builtblocks to be assembledon-site.These fireplaces may be installed on either combustible ornon-combustiblefloors. In order for the fireplace to be installed on a combustible floor though, it is necessary that the fireplace be supported on a platform orsub-floorthat isnon-combustible.

The Four Components of the Grand Meridian

Fireplace:

Combustible or Non-CombustibleFloor

Non-CombustibleRaised Platform

Firebox and Smoke Dome

FMI PRODUCTS, LLC chimney system required.

Important: Follow the chimney pipe manufacturer’s instructions on the installation of their specific flue system.

Careful step-by-stepinstructions for each phase of the installation procedure will be given for the Grand Meridian conventional radiant heat fireplaces. Those instructions generally fall into the following categories:

Spacing and clearance as it relates to combustible materials.

Familiarity of installation for all components.

The strength of the floor on which it rests.

Chimney system measurements.

Choice of materials and craftsmanship in fireplace and hearth finishing.

3.A location that avoids cutting of joists or roof rafters will make installation easier.

4.An outside air kit is available with this fireplace

(see Optional Outside Air Kit on page 12).

Maximum distance between elbows is 6 feet. For systems with two elbow sets, minimum height is 22 feet. Maximum height of any system is 40 feet. This measurement includes fireplace, chimney sections and height of termination assembly at level of the flue gas outlet (see Figure 20, page 16).

Framing

1.Frameopeningforfireplaceusingdimensionsshown in Figures 6 and 7.

2.If fireplace is to be installed directly on carpeting, tile (other than ceramic) or any combustible material other than wood flooring, fireplace must be installed upon a metal extending full width and depth of fireplace.

3.Set fireplace directly in front of this opening and slide unit back until nailing flanges touch side framing.

4.Check level of the fireplace and shim with sheet metal if necessary.

5.Before securing fireplace to prepared framing, ember protector (provided) must be placed between hearth extension (not supplied) and under bottom front edge of fireplace to protect against glowing embers falling through. If fireplace is to be installed on a raised platform, a Z-typeember protector (not supplied) must be fabricated to fit your required platform height. Ember protector should extend under fireplace

a minimum of 1 1/2". Ember protector should be made of galvanized sheet metal (26 gauge minimum to prevent corrosion.

6.Using screws or nails, secure fireplace to framing through flanges located on sides of fireplace.

Mantel and mantel shelf clearances

As with any radiant heat fireplace, the Grand Meridian fireplaces must comply with building code safety clearances, per units that have openings of 6 sq. ft. or greater. For Mantel clearances see Figure 5, page

7. Walls that Adjoin – Safety codes and all practical outlooks insist that your fireplace cannot be installed closer than 2 ft. to any walls in the room the fireplace is housed in or to any walls of adjoining rooms.

Caution in Regards to Combustibles – If any part of the fireplace or objects in the room (curtains, rugs, paint, cushions, etc.) start to show warping or discoloration due to heat from the fireplace, it is time to take immediate action. Do not use the fireplace until you have figured out how to address the problem.

You are facing a potential fire hazard. FMI PRODUCTS, LLC cannot be responsible for the make-upof material on the exterior of the fireplace you have chosen, nor can FMI PRODUCTS, LLC be held responsible for the materials in a room that may be responding negatively to heat. However, in almost all cases, there is a solution to the problem, either by making adjustments to airflow or the modifications to the room itself.

Hearth Extension

Where the flooring material at the opening of the fireplace is combustible, it is required that the hearth extension be covered with a non-combustiblematerial.Allhearthextensionsmustbemadeofcoderated,non-combustiblematerials such as tile, brick, marble, concrete or stone. The extension should be set flush against the front of the fireplace front and measure 20" minimum at the front and 12" minimum beyondthesidesofthefireplaceopeningasshownin

Figures 8 and 9 (page 9). These relative dimensions are also covered by code.

If a raised hearth extension is being installed, it must be constructed of non-combustiblematerial and any material under the structure must also be noncombustible.

If using a raised hearth or metal base plate, note that a combustible wood header must be no closer than 2" to the top of the dome (see Figure 6, page 8).

Attention: You will note that there will be a gap between the fireplace front and the extension of thenon-combustiblehearth material. Be certain that you seal this withnon-combustiblematerial.

These Grand Meridian Fireplaces have been designed with clearance to combustible floors as indicatedinPage8.Coveranypartofthecombustible floor system left exposed with 1” (one inch) thick ceramic fiber insulation rated up to 2,100° F.

Attention: It is critical to abide by the clearances listed in this manual for all components specified as it allows for movement of hot air from the fireplace into interior areas of the chimney chase. Also, be certain that the chimney system be installed as stated below.Prior to starting the installation, check with local, regional or state codes for any restrictions or required permits regarding your fireplace installation.

NOTE: It is required that ember protector strips must be laid on the fiber of the non-combustibleraised platform(see Figure 10). These are included with the

Metal Base accessory.

WARNING: Hearth extension is to be installed only as shown in Figure 10.
