product overview Introduction We extend a warm welcome from all of us at FMI PRODUCTS, LLC, proud manufacturers of the Grand Meridian Fireplaces. Thank you for choosing FMI. You may have thought long and hard before you chose the fireplace which would grace your home. Rest assured that every component of the Fireplace has been tested to ensure long-term durability. Product Overview The Grand Meridian Fireplaces are designed as factory-built blocks to be assembled on-site.
pre-Installation preparation selecting location To determine the safest and most efficient location for the fireplace, you must take into consideration the following guidelines: 1. The location must allow for proper clearances (see Figures 6 and 7). 2. Consider a location where fireplace will not be affected by drafts, air conditioning ducts, windows or doors. 3. A location that avoids cutting of joists or roof rafters will make installation easier. 4.
pre-Installation preparation Continued WARNING: Failure to position the parts in accordance with these diagrams or failure to use only parts specifically approved with this appliance may result in property damage or personal injury. Maintain the 2" clearance to combustibles above the dome. DO NOT attach combustible materials on top of the dome. 18" MIN* H** 8" MIN* Non-combustible facing (not supplied). Condition Dim.

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.

Venting Installation Optional Outside air Kit (Model MM4AK) The Grand Meridian Fireplace needs enough replacement air to function properly and some local building codes may require outside combustion air to be provided. If no replacement air is provided, improper flue drafting may occur, creating negative pressure whereby smoke may enter the home, especially in homes that are very well insulated and tightly sealed. Check local building codes for specific requirements.

The pipe sections must be assembled independently as the chimney is installed. When connecting chimney directly to the fireplace, the inner flue pipe section must be installed first with the lanced side up.

Supporting floor system Installation It is the ultimate responsibility of the installer to ensure that proper concrete slab supports are used. WARNING to the licensed design professional and/or building contractor: It is your responsibility to be certain that the Grand Meridian can be properly supported by the combustible floor system on which the fireplace will rest. For fireplace support foundations installed on concrete refer to Appendix I and II (pages 42 & 43) for specific instructions.

Fireplace Installation You will find that the Grand Meridian Fireplace is designed to be completely assembled on-site, consisting of interlocking precast parts. Included is a thinset type mortar for bonding. The parts of the fireplace are made of FMI’s incredibly strong blend of specialty cement and a light weight aggregate. IMPORTANT: When applying mortar, it is imperative that the concrete blocks be maintained moist (not soaking) so they don’t absorb the water out of the mortar and cause adhesion to fail.
fireplace installation Continued you can nudge them in between openings to achieve the precision you need in making component adjustments. Once you have removed any shims, you will want to cover any gaps that may have resulted with the mortar. Assembly Instructions 1) Place the hearth base on top of your non-combustible floor or metal base. For concrete slabs, supporting floor needs to be rated at ASTM 90.
fireplace installation Continued 6) Assemble the first layer as shown in Figure 38 and 39. Continue to the next layer sides and rear pieces, keeping components moist, mixing mortar as you need it and threading the mortar appropriately as you stack each section, one onto the next. Constantly check for squareness and levelness while building each course of block. As you complete each piece, make certain that you adhere the mortar at each and every joint.
fireplace installation Continued 7) Insert 28" long rebar (8 total, included with fireplace) vertically through the cells, into the holes in the hearth, adjacent to the rebar and/or all-thread sticking up from the hearth (Figure 42). Mix approximately 2 cu. ft. of Ready-Mix Concrete (not included) and fill all cells in walls and rear of firebox completely (Figure 41).
fireplace installation Continued Note: Although you are cautioned to use mortar sparingly because it does have such holding power, you should look over the firebox assembly at the end and fill in any gaps, especially joint connections, with the mortar. Important: Adjustments can only be made while the mortar is still wet when correcting for squareness and leveling. 11) Assemble Lower Dome Sides as shown in Figure 46. The beveled face lines up with the inward angles of the lintel sides.

Installers are cautioned to put the chimney system together exactly as instructed in the Venting Installation on page 12.
firebrick installation Refractory Firebrick lining must be installed. There are two options. You can obtain pre-fabricated Modular Firebrick Liner from FMI PRODUCTS, LLC (see Accessories on page 33) or custom firebrick lining can be installed. Modular Firebrick Lining If using FMI PRODUCTS, LLC Module Firebrick Liners, simply use an extra bag of the mortar we supply. Install Hearth panel first, rear panel next and side panels last.
Operation and maintenance guidlines Fireplace Grates To complete your fireplace installation, a fireplace grate will be required for safe operation. The fireplace grate can be obtained from FMI PRODUCTS, LLC (see Accessories on page 33) or if choosing an alternate, it must be sized to 50% of the hearth maximum. Additionally. A fireplace screen must be installed for safety.
Operation and maintenance guidlines Continued Second Lighting – Start the fire slowly and gradually as you did with the first lighting, but this time you can burn up to ten pounds of firewood, probably four to five logs that are 3" in diameter. With the second lighting you can let the fire burn two hours – no more.
