Carbon Monoxide Poisoning: Early signs of carbon monoxide poisoning resemble the flu, with headaches, dizziness, or nausea. If you have these signs, the fireplace may not be working properly.Get fresh air at once! Have the fireplace serviced.

Note: Some people are affected more than others by carbon monoxide. These may include pregnant women, people with heart or lung disease, are anemic, anyone under the influence of alcohol, and those at high altitude.

IMPORTANT:Readthisownersmanualcarefully and completely before trying to assemble, operate, or service this fireplace. Improper use of this fireplace can cause serious injury or death from burns, fire, explosion, electrical shock, and carbon monoxide poisoning.

General Safety Concerns

1.If you smell gas

Shut off gas supply.

Do not try to light any appliance.

Do not touch any electrical switch; do not use any phone in your building.

Immediately call your gas supplier from a neighbor’s phone. Follow the gas supplier’s instructions.

If you cannot reach your gas supplier, call the fire department.

2.This fireplace shall not be installed in a bedroom or bathroom.

3.Never install the fireplace

In a recreational vehicle.

Where curtains, furniture, clothing, or other flammable objects are less than 36 inches from the front, top, or sides of the fireplace.

In high traffic areas.

In windy or drafty areas.

4.Do not use this fireplace as a wood-burningfireplace.

5.Do not add extra logs or ornaments such as pine cones, vermiculite, or rock wool. Using these added items can cause soot build-up.

6.This fireplace is designed to be smokeless. If logs appear to smoke, turn off fireplace and call a qualified service person.

7.Avoid any drafts that alter burner flame patterns. Do not allow fans to blow directly into the fireplace. Do not place a blower inside burn area of the firebox. Ceiling fans may create drafts that alter burner flame patterns. Soot build-upand improper burning will occur. Sootbuild-upcan settle on household surfaces outside the fireplace.

8.This fireplace needs fresh air ventilation to run properly.

The Vent free decorative gas log set must have an oxygen depletion sensor (ODS) pilot light safety system. The ODS shuts down the fireplace if not enough fresh air is available. See Air for Combustion and Ventilation, page 8. If the fireplace keeps shutting off, see appliance manufacturers’ troubleshooting instructions.

9.Do not run fireplace

Where flammable liquids or vapors are used or stored.

Under dusty conditions.

10.Do not use this fireplace to cook food or burn paper or other objects.

11.Never place any objects in the fireplace or on logs.

12.Fireplace screens must be provided and are to be closed before operating the decorative room heater. If doors are installed, they must be open during operation. Fireplace front and screen become very hot when running fireplace. Keep children and adults away from hot surfaces to avoid burns or clothing ignition. The fireplace will remain hot for a time after shut down. Allow surfaces to cool before touching.

13.Carefully supervise young children when they are in the room with the fireplace.

14.Do not use fireplace if any part has been exposed to or under water. Immediately call a qualified service technician to inspect the fireplace and to replace any part of the control system and gas control which has been under water.

15.Do not operate the fireplace if any log is broken. Do not operate the fireplace if a log is chipped (dime-sizedor larger). Verify proper log placement prior to operating appliance.

16.Turn fireplace off and let cool before servicing. Only a qualified service person should service and repair the fireplace.

17.Operating the fireplace above elevations of 4,500 feet may cause pilot outage.

DO NOT USE OR STORE GASOLINE OR OTHER FLAMMABLE LIQUIDS OR GASES IN OR NEAR THE

FIREPLACE!

ATTENTION:Afireoranexplosioncouldoccurcausingproperty damage, injury or loss of life if you do not follow the information in this manual!

Projected installations can extend any distance into the room. A projection may be ideal for a new addition on an existing, finished wall.

Corner installations make use of space that may not normally be used and provides a wider and more efficient range for heat disbursement.

An internal wall installation provides a discreet option for room separation and can also be ideal as an addition to an existing wall.

IMPORTANT:Vent-freeheatersaddmoisturetotheair.Installinga fireplace in rooms without enough ventilation air may cause mildew to form from too much moisture.

IMPORTANT: Make sure the fireplace is level. If the fireplace is not level, the log set will not work properly.

Attention: You may need a building permit to install a Grand Meridian fireplace. Check with the local jurisdiction before you get started.

Supporting Floor Systems

Floor Framing

It is important to take into consideration that the load for the Grand Meridian Fireplace is considerable, but, more important, that it is a dead load that will have to be absorbed by a relatively small amount of existing floor space.

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 17 & 18) for specific instructions.

Rebar locations

Lay-outthe position of the fireplace and drill holes where the rebar will be located. Secure the #3 rebar 4 inches into the concrete foundation with ITW Epoxy or Simpson Epoxy. Follow manufacturer’s instructions for installation of rebar into slab.

Wood Floor

Anchorage of fireplace to wood floor construction is required. Refer to Figure 8 for anchorage dimensions. Four anchors are required to attach to thesub-flooringframing.

Crawl Space or Upper Floor:

For installation of firebox over combustible crawl spaces or upper floors, anchorage of the firebox is required. Illustrations of examples of possible anchorage methods are shown in Figures 5 thru 7 depending upon the type of floor framing. Final method of anchorage is to be determined by licensed design professional.

6

For conventional framing, where the floor joists are parallel with the sides of the firebox, the addition of floor joists to align with the anchor brackets allows the brackets to be directly connected to the floor joists.

Note that additional floor joists may be required to support the weight of the firebox and chimney. Where the floor joists run paralleltothefrontofthefirebox,anchoragecanbeaccomplished in like manner as shown in Figure 5 using blocking between the floor joist.

For floors supported by I-Joists,the method of anchorage is illustrated in Figures 6 and 7. Figure 10 illustrates the general arrangement of anchorage to floor framing.

It is important to take into consideration that the load for the Grand Meridian Fireplace must be considered as additional dead load that will have to be supported by the floor framing. Additional floor joists or I-joistsmay be required as determined by the licensed design professional.

The dead weights for the fireplace are noted in Table I. It is the task and responsibility of the general contractor/installer to see that the proper reinforcement for weight loads are made by a licensed design professional prior to the fireplace installation.

As stated above, it is desirable to place additional framing for alignment of anchor rods. Refer to Figure 10 for anchor rod locations.

Clearances

The Importance of Clearances

Warning to the structural engineer and/or building contractor: It is your responsibility to be certain that the Grand Meridian Fireplace can be properly supported by the combustible floor system on which the fireplace will rest. Be advised that this engineering equation will be in addition to any live or dead weights that the floor has to carry.

Clearances to Combustibles

Nothing is more important than paying strict attention to giving clearance between fireplace surfaces and surrounding “combustibles” the most common of which are:

Drywall

Wood flooring

Plywood sub-flooring

Framing materials

Particle board

Mill board

Plywood paneling

Required Clearances are:

 

Unit front, sides, rear:...........................................

0"

Combustible Floor: ..............................................

0"

Combustible Sheathing above opening top: .......

8" (200 mm)

Sheathing or trim to opening sides: .....................

8" (200 mm)

Mantle above opening: ........................................

12" (300 mm)

Opening to sidewall: ............................................

24" (500 mm)

Insulation from firebox: ........................................

0"

The Grand Meridian Vent-Freefireplace may be installed at “zero clearance” to plywood sheathing and to uninsulated wood framing members at the unit bottom, sides, rear and top when used for enclosing any listedvent-freegas-firedlog set with maximum heat input ratings up to 40,000 Btu/hr. However, when aVent-Freefireplace is to be installed on carpeting, wood flooring, or any combustible material other than tile or concrete, the Vent-Free fireplace shall then be installed on a metal or wood platform extending the full width and depth of the VentFree fireplace.

Clearance to Combustible Trim:

Grand Meridian Vent-FreeFireplaces are designed to be custom finished with facing trim and mantle to be an owner option. However, all such trim material must meet standard fireplace code requirements.

Non-combustiblefacing material must be applied to a minimum of eight inches (8”) beyond the sides of the finished opening of theVent-Freefireplace andnon-combustiblefacing material must cover a minimum of twelve inches (12”) above the finished opening of the installed unit.

Clearance to combustible trim are those distances required to ensure that combustible mantle and facing material will not be exposed to excessive heat while the unit is operating.

These clearances should be adequate to prevent discoloration or warping of trim facings due to heat. However, circumstances unique to each installation create variables that may be beyond the scope of this manual. Therefore be sure to follow gas log appliance manufacturer’s explicit installation instructions regarding all minimum trim facing, mantle height and side wall clearance requirements.

Figure 13

Parts of the combustible mantle assembly located above and projecting more than one and one-halfinches(1-1/2”)inches from the firebox opening shall be kept at least twelve inches (12”) from the top of the opening.

Mantle shelves with horizontal projection of ten inches (10”) from the face of the fireplace must be held to a minimum vertical distance of twenty inches (20”) from the top of the finished fireplace opening.

Note: Mantle height clearances may vary among gas log appliance manufacturers or with the use of firebox canopies.

Be sure to follow the gas log appliance manufacturer’s explicit installation instructions for mantle height clearance requirements.

9

Interior Wall Materials:

Wall materials, such as drywall, should be set flush with the rough front face of the Vent-Freefireplace. This will allow for placement of requirednon-combustiblesurround material in such a way that the surround material can lay flat against the finished wall surface and also align with the leading edge of the fire brick interior of theVent-Freefireplace (seeFigure 15).

Trim Facings:

Parts of the combustible mantle assembly located along the sides of the firebox opening, which project more than one and one-halfinches(1-1/2”)from the face of the fireplace, shall be kept at least eight inches (8”) from the firebox opening.

Adjoining Room Walls:

Interior wall surfaces of adjoining room walls must be at a minimum horizontal measure of twenty four inches (24”) away from the finished opening of the Vent-Freefireplace.

Air for Combustion and Ventilation

Energy efficient homes require homes to be airtight but at the same time provide sufficient fresh air to breathe. Fresh air enters the home through air conditioning duct vents, around doors and windows but also must provide enough fresh air for proper combustion on all fuel-burningappliances in the home. Exhaust fans, fireplaces, clothes dryers, andfuel-burningappliancesdrawairfromthehousetooperate.Youmustprovide adequate fresh air for these appliances. This will insure proper venting of ventedfuel-burningappliances.

Figure 16

Providing Adequate Ventilation

In accordance with the National Fuel Gas Code NFPA 54/ANSI Z223.1, Section 5.3, Air for Combustion and Ventilation, all spaces in homes fall into one of the three following ventilation classifications:

1.Unusually Tight Construction

2.Unconfined Space

3.Confined Space

The following information will help you classify your space and provide adequate ventilation.

Unusually Tight Construction

The air that leaks around doors and windows may provide enough fresh air for combustion and ventilation. However, in homes of unusually tight construction, you must provide additional fresh air. Unusually tight construction is defined as construction where:

a.Walls and ceilings exposed to the outside atmosphere have a continuous water vapor retarder with a rating of one perm* or less with openings gasketed or sealed and...

b.Weather stripping has been added on openable windows and doors and...

c.Caulking or sealants are applied to areas such as joints around window and door frames, between sole plates and floors, between wall-ceilingjoints, between wall panels, at penetrations for plumbing, electrical, and gas lines, and other openings.

* A perm is a unit of permeance or water vapor transmission, the US perm-inchis defined as the passage of 1 grain of vapor through 1 square foot of 1 inch thick material in 1 hour under a pressure difference of 1 inch of mercury.

If your home meets all the three criteria above, you must provide additional fresh air.

10

Unconfined Space

An unconfined space has a minimum total air volume of 50 cu.ft. (cubic feet) for each 1,000 Btu/Hr input rating of all appliances in the total space (cu.ft. = length x width x height of space). Include adjoining rooms only if there are doorless passageways or ventilation grills between the rooms. If the Btu per 50 cu.ft. is less than 1,000 Btu/Hr, then fresh air will be provided by the natural air flow into the house.

Confined Space

Aconfined space has an air volume of less than 50 cu.ft. for each 1,000 Btu/Hr input rating of all appliances in the space (cu. ft. = length x width x height of space). Include adjoining rooms only if there are door less passageways or ventilation grills between the rooms.

Determining Total Air Volume

Use this work sheet to determine if you have a confined or unconfined space. The space to be considered includes not only the room in which you will install the fireplace but also any adjoining rooms with ventilation grills between them or door less passageways.

1.Determine the total volume of your space L x W x H = _______ cu.ft.

Example: Space size = 20 ft. long x 20 ft. wide x 8 ft. high (ceiling height) = 3,200 cu.ft.

If adjoining ventilation to adjoining room is supplied with grills or openings, add the volume of these rooms to the total volume of the space.

2.Divide the space volume by 50 cu.ft. to determine the maximum Btu/Hr the space can support.

_______ cu.ft. (volume of space)

50 cu ft. = (Maximum Btu/Hr the space can support) Example: 3200 cu ft. (Volume of space) / 50 cu. Ft. = 64.0 or 64,000 (maximum Btu/Hr the space can support.)

3.Add the Btu/Hr of all fuel burning appliances in the space.

4.Compare the maximum Btu/Hr the space can support with the actual amount of Btu/Hr used.

_________ Btu/Hr (maximum the space can support)

_________ Btu/Hr (actual amount of Btu/Hr used)

Example:

64,000 Btu/Hr (maximum the space can support)

76,000 Btu/Hr (actual amount of Btu/Hr used)

The space in the previous example was a confined space because the actual Btu/Hr used was more than the maximum Btu/Hr the space could support. If you find you have a Confined Space, you must provide additional fresh air. Your options are as follows:

a)Re-workworksheet, adding the space of an adjoining room that may not have qualified for the extra volume. If the extra space provides enough volume to convert the area to an unconfined space, remove door to adjoining room or add ventilation grills between rooms.

b)Vent room directly to the outdoors.

c)Install a lower Btu/Hr gas log (if lower Btu/Hr size makes room unconfined).

If the actual Btu/Hr used is less than the maximum Btu/Hr the space can support, the space is an unconfined space. You will need no additional fresh air ventilation.

WARNING: If the area in which the heater may be operated is smaller than that defined as an unconfined space, provide adequate combustion and ventilation air by one of the methods described in the National Fuel Gas Code, ANSI Z223.1 Section 5.3 or applicable local codes.

Local codes may have stricter definitions for confined space and/or for unusually tight construction. Installing our optional outside air kit may allow the space to be classified as not being unusually tight or being an unconfined space. Check you local codes.

IMPORTANT: Do not provide openings for inlet or outlet air into an attic if the attic has athermostat-controlledpower vent. Heated air entering the attic will activate the power vent.

ImportantPre-installationInformation

Overview

You will find that the Grand Meridian Fireplace is designed for complete assembly at your construction site with all necessary items delivered consisting of interlocking precast parts, 50 lbs. of mortar and rebar.

The parts of the fireplace are made of incredibly strong blend of specialty cement and a lightweight aggregate.

Thedesignofthefireplacecallsfortheinstallationofarefractory fire brick liner. This should be a minimum of 1-1/8”thick. The liner will be applied within the walls of the firebox. Modular firebrick panels are also available from FMI PRODUCTS, LLC.

Additional Materials Required:

1) Ready-Mixconcrete - 2 cu.ft.

SURFACE CRACKS - The Grand Meridian FIREPLACES are manufactured using high quality materials. During the drying process,surfacecrackingmayoccur.Thesesmallcracks(under 1/16” will not affect the fireplace safety or performance). During the assembly process, fill surface cracks withthin-setmortar and brush when drying for a smooth surface finish.

Leveling and Aligning Components:

It is important to assemble all Vent-Freefireplace components flush, level and square. Since it is not intended that mortar be used to lay a mortar joint of any measurable thickness as is typical when laying brick or concrete block, adjustments in component height and level alignments are accomplished with the use of small shims. These shims can be tapped into place to level and align components. Once the Mortar is set, the shims must be removed completely.

Be sure to re-groutany and all gaps where shims have been inserted and then removed or where contact surfaces have been separated by shim leveling.

Field Assembly Procedures

1)Mixing the mortar – You will require a 50 lb. bucket of mortar which will be more than enough to adequately affix all the fireplacecomponents,onetothenext.Themortarispremixed anddryandistobeusedtoadhereallthefireplacecomponents. Be sure to use clean water and work it up into a mixture that is pasty but not lumpy. If it is too thin, the components will not adhere. Some trial and error may be necessary. You will want to apply the mixture with a standard grout bag.

2)Moisten all surfaces which will have grout applied prior to assembly. This will minimize shrinkage and cracks developing in the joint areas. Best way to accomplish this is with a bucket of water and a large sponge. Dip sponge into water and apply a liberal amount of water to the grout joint surface several minutes before the part is to be assembled. The water will absorb into the surface allowing the grout to properly cure.

3)Assembly of the Components – Once you have found the proper consistency of the mixture, load it into the grout bag andthenplacethecomponentstogetherapplyingthemixture

directly to the components where they come together. As a rule, you can figure that you should lay down about ½” (onehalf inch) of a thread of mortar. The line of mortar should be approximately ½” (one-halfinch) away from all the edges of each separate component.

The mortar has a considerable amount of holding power so do not overload the components with too much mortar.

4)You will notice that some mortar will “ooze out” when you place the next component on top of or next to the component you previously place. This is to be expected – it means the two pieces have properly bonded --and you will want to swipe the excess away with a trowel. It is never intended that the surfaces of the components are to be completely covered with mortar.

5)Do not apply the mortar in thick bands even if the component you are working with is larger than the rest. You will want to apply “stripes” of mortar in these situations.

6)Making Sure Components Are Level – It is extremely important that you pay careful attention to how you are assembling the fireplace. Since every component builds on the next, it is critical, that from the beginning, you are checking that the components are fitting together to be level and flush. If you have to make any kind of an adjustment, do not try to do it “by loading an opening” with mortar. That is completely unacceptable, resulting in a fireplace that will not be plumb or level. What you are advised to do is make use of shims. You will find these supplied with the fireplace and you can nudge them in between openings to achieve the precision you need in making component adjustments.

7)Once you have removed the shims, you will want to cover any gaps that may have resulted with the grout.

Warning: All surfaces where grout is applied must have water sponged on several minutes prior to assembly. This will minimize cracking of grout joint and provide maximum strength.

6)Keep the assembly of the next sections of the firebox side walls moving up, 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 section, make certain that you adhere the mortar at each and every joint.

7)When you have arranged all the components into place and you are working on the top rear firebox, check that your work is level. If you need to, you can make some adjustments in the top surface of the box assembly simply by using shims. Once you are satisfied with the degree of levelness, you can address any gap that may have occurred with an appropriate amount of mortar.

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 any gaps with mortar especially at joint connections. Adjustments must be made to ensure the fireplace is level and square while the mortar is still wet.

8)After fourth row of walls are in place, add 36” rebar to all cells as shown in Figure 22. The rebar should enter the holes in the Hearth and lie adjacent to the 12” rebar secured in subfloor. Then fill cells with approx. 2 cu.ft.Ready-MixConcrete.

For a “flush hearth” (fireplace floor flush with the room’s floor) the base plate can be omitted from the assembly and the firebox walls built directly on the concrete support slab. The fire brick floor of the firebox is then set directly to the concrete support slab. This makes the fireplace finished fire brick floor approximately one and one-halfinches(1-1/2”)above the top of the concrete support slab.

Gas Piping Installation

The provision for installation of a gas pipe is only for connection to a Vent free decorative gas log sets meeting standard ANSI Z21.11.2

Familiarize yourself with requirements for installation as outlined by the National Fuel Gas Code, ANSI Z223.1.

This gas pipe provision must only be connected to an approved vent-freegas log heater certified to ANSI Z21.11.2 heater standard. Check local building codes for specific pipe and material requirements.

1)Gas piping can be routed from the floor, rear or side walls. With a masonry drill, follow the instructions from the gas appliance manufacturer. Any wires must be routed through separateconduit.Makesureprovisionsaremadeforaccess to manual shut-offvalve.

Firebrick Liner Installation

Initial Fireplace Operation

It is required that the interior sides, rear and bottom be lined with minimum 1-1/8”thick firebrick.Pre-fabricatedfire brick liner walls can make the installation easier.

All required through-wallaccesses (gas and electrical line feeds and combustion air supply access holes) should be drilled before the required fire brick lining is installed.

Modular Firebrick Lining

If using FMI PRODUCTS, LLC Firebrick Liners, simply use an extra bucket of mortar. Install Hearth Liner first, rear next and sides last. Consider if brackets for grates will be required, also if pre-drillingis required for gas lines, electrical or if the outside combustion air kit is to be installed.
