The Grand Meridian Fireplaces are designed as  
factory-built blocks to be assembled on-site. These  
fireplaces may be installed on either combustible or  
non-combustible floors. In order for the fireplace to  
be installed on a combustible floor though, it is nec-  
essary that the fireplace be supported on a platform  
or sub-floor that is non-combustible.  
Figure 4: Typical Installations  
Note that each of these topics will be covered in de-  
tail and that the installer is expected to understand  
each phase completely before going on to subse-  
quent instructions.  
The Four Components of the Grand Meridian  
Fireplace:  
Combustible or Non-Combustible Floor  
Non-Combustible Raised Platform  
Firebox and Smoke Dome  
aTTenTIon: Be advised that all the illustrations in  
this manual are for general reference only. Do not  
scale drawings. Actual design elements will vary  
from case to case. Pay attention to specified mini-  
mum clearances to combustibles.

Testing and listing for these Grand Meridian Fireplac-  
es has been undertaken by the PFS Corporation.  
IMPoRTanT: Follow the chimney pipe  
manufacturer’s instructions on the installation of  
their specific flue system.  
aTTenTIon: You may need a residential building  
permit to install a Grand Meridian Fireplace. Consult  
local jurisdictions before you get started!  
If asked, advise the local authorities that the  
FMI Fireplace is designed for installation per the  
National Fire Protection Association Standard  
for Chimneys, Fireplaces, Vents and Solid  
Fuel-Burning Appliances (NFPA211).  
Careful step-by-step instructions 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:  
When choosing the location of your FMI Fireplace,

pre-installation preparation  
seleCTInG loCaTIon  
WaRnInG: do not pack required air spaces  
with insulation or other materials.  
To determine the safest and most efficient location  
for the fireplace, you must take into consideration the  
following guidelines:  
Minimum/Maximum Chimney Height for  
Residential Installation  
1. The location must allow for proper clearances (see  
Figures 6 and 7).  
Minimum height of chimney, measured from base of  
fireplace to flue gas outlet of termination, is 14 feet  
for straight flue or 17 feet for a flue with one elbow  
set. 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).  
2. Consider a location where fireplace will not be af-  
fected by drafts, air conditioning ducts, windows or  
doors.  
3. A location that avoids cutting of joists or roof raf-  
ters will make installation easier.  
4. An outside air kit is available with this fireplace  
(see Optional Outside Air Kit on page 12).  
MInIMUM CleaRanCe To CoMBUsTIBles  
FRaMInG  
The distance to be maintained from the surfaces  
of the fireplace to combustibles must be observed.  
Below is a list of the most common combustible  
materials to name a few:  
1. Frame opening for fireplace using dimensions shown  
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 fire-  
place.

Hearth extension beyond front.............................20"  
Hearth extension beyond sides............................12"  
Insulation from firebox............................................2"  
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 em-  
bers falling through. If fireplace is to be installed on  
a raised platform, a Z-type ember protector (not sup-  
plied) 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 pre-  
vent corrosion.  
6. Using screws or nails, secure fireplace to framing  
through flanges located on sides of fireplace.

aTTenTIon: You will note that there will be a gap  
ManTel and ManTel sHelF CleaRanCes  
between the fireplace front and the extension of the  
non-combustible hearth material. Be certain that  
you seal this with non-combustible material.  
As with any radiant heat fireplace, the Grand Merid-  
ian 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.  
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, re-  
gional or state codes for any restrictions or required  
permits regarding your fireplace installation.  
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 dis-  
coloration 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 PROD-  
UCTS, LLC cannot be responsible for the make-up  
of material on the exterior of the fireplace you have  
chosen, nor can FMI PRODUCTS, LLC be held re-  
sponsible 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.  
NOTE: It is required that ember protector strips must  
be laid on the fiber of the non-combustible raised plat-  
form (see Figure 10). These are included with the  
Metal Base accessory.

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

or Straps (Min. of 1/4" x 20" in size)  
The Grand Meridian Fireplace needs enough re-  
placement 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, es-  
pecially in homes that are very well insulated and  
tightly sealed. Check local building codes for specific  
requirements.  
Air Inlet  
Location  
Must  
Allow For  
Bushes  
or Snow  
The installation of an outside air kit should be per-  
formed during the rough framing of the fireplace due  
to the nature of it's location. Outside combustion air  
is accessed through a vented crawl space or through  
a sidewall (Figure 13). If crawl space is used, check  
local codes for proper termination.  
Be sure that you carefully check the source of the  
outside air before you choose the site for your air in-  
take. You don’t want a place where snow will collect,  
where bushes or trees will be growing or a location  
that is too close to any other structure.

Each double wall chimney section consists of a gal-  
vanized outer pipe, a stainless steel inner flue pipe  
and a wire spacer. The pipe sections must be as-  
sembled 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. The outer pipe section can  
then be installed over the flue pipe section with the  
hemmed end up. Press down on each pipe section  
until the lances securely engage the hem on the fire-  
place starter. The wire will assure the proper spacing  
between the inner and outer pipe sections.

pipe sections are locked together. When installing  
double wall snap-lock chimney together, it is impor-  
tant to assure the joint between the chimney sections  
is locked. Check by pulling chimney upward after  
locking. The chimney will not come apart if properly  
locked. It is not necessary to add screws to keep the  
chimney together (exception, see Figure 15).

FIResToP sPaCeRs (Fs-10)  
Firestop spacers are required at each point where the  
chimney penetrates a floor space. Their purpose is to  
establish and maintain the required clearance between  
the chimney and the combustible materials. When the  
pipe passes through a framed opening into a living  
space above, the firestop must be placed onto the ceil-  
ing from below as shown in Figure 18.  
5. Add next sections of pipe until end penetrates roof  
line. Check to see that proper clearances are main-  
tained. Extend chimney by adding sections of double  
wall pipe until pipe is minimum of 30” above highest  
point of roof cutout. Termination and chimney must  
extend a minimum of 36” above highest point where  
it passes through roof.  
They also provide complete separation from one floor  
space to another or attic space as required by most  
codes. When the double wall pipe passes through a  
framed opening into an attic space, the firestop must be  
placed into an attic floor as shown in Figure 19.

refer to the installation instructions supplied with the  
termination.  
Determine the flashing to be used with the roof open-

Installing Flashing on a Metal Roof  
When installing the flashing on a metal roof, it is re-  
quired that putty tape be used between the flashing  
and the roof. The flashing must be secured to the  
roof using #8 x 3/4" screws and then sealed with roof  
coating to prevent leakage through the screw holes.  
A roof coating must also be applied around the pe-  
rimeter of the flashing to provide a proper seal.

You will find that the Grand Meridian Fireplace is de-  
MaTeRIals InClUded:  
signed to be completely assembled on-site, consist-  
ing of interlocking precast parts. Included is a thin-  
set 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.  
MM33, MM39, MM44, MM49:  
• 8 - ⅜" Rebar x 28" Long  
• 8 - ⅜" Rebar x 12" Long  
• 1 - 50 lb. bucket Mortar  
• 20 - Small Wood Shims  
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. Frequently run a  
damp sponge to the parts before mortar is applied!  
MM63:  
• 10 - ⅜" Rebar x 36" Long  
• 10 - ⅜" Rebar x 12" Long  
• 2 - 50 lb. bucket Mortar  
• 20 - Small Wood Shims  
The installation of an anchor plate/damper for either  
masonry chimney or pre-fabricated chimney is re-  
quired but not supplied. See Accessories on page  
33.  
FIeld asseMBlY PRoCedURes  
Mixing the mortar – The mortar comes pre-mixed  
and should be dry. Be sure to use clean water and  
work it up into a mixture that is pasty but not lumpy.  
If it’s too thin and the surfaces don’t stay moist, the  
components will not adhere. Load the mixture into a  
standard grout bag.  
The installation of a seismic strap kit is required but  
not supplied. See Accessories on page 33.  
An optional outside air kit can be used. See Acces-  
sories on page 33.  
Refractory Firebrick Liners also need to be installed.  
These should be a minimum of 1⅛" thick. The liner  
will be applied within the walls and hearth area of the  
firebox. See Accessories on page 33.  
When applying, use about ½" thread of mortar. The  
mortar bead should be approximately ½" away from  
all edges. The mortar has a considerable amount of  
holding power so do not overload the components  
with too much mortar. Keep the components moist  
at all times by wiping them down with a clean wet  
sponge.  
Tools needed FoR InsTallaTIon:  
• One 4 ft. level  
• Roto-hammer with ½" drill bit  
• Drill motor with mixer blade to mix Mortar  
• Two empty 5 gallon buckets to mix Mortar  
• One wheelbarrow and shovel to mix concrete  
• Grout bag  
Some mortar will “ooze out” when placing compo-  
nents together, this is normal. Wipe excess away  
with a trowel. Do not cover component surfaces com-  
pletely with mortar. 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.  
• Triangular masonry trowel  
• Rubber hammer  
Make sure components are level. Checking lev-  
elness after each layer. It’s extremely important  
that you pay careful attention to how you are as-  
sembling the Grand Meridian Fireplace since ev-  
ery component builds on the next. If you have to  
make any kind of an adjustment, do not try to do it  
“by loading an opening” with mortar, this will only  
result in a fireplace that will not be plumb or level.  
Use wood shims instead. You will find these small  
wood shims supplied with the Fireplace and

Apply mortar  
between joints  
1) Place the hearth base on top of your non-combus-  
tible floor or metal base. For concrete slabs, support-  
ing floor needs to be rated at ASTM 90.  
a) Combustible Floor Installations: Mix up a  
batch of mortar and adhere hearth slabs to the  
cement board (see Figure 32 & 33, page 21). All-  
thread rods should stick up through the holes on  
the hearth slabs.

b) non-combustible Floor Installations: Draw  
an outline of the hearth area based on the dimen-  
sions shown in pages 4 and 5. Position Hearth  
slabs and mark rebar center locations. Drill 4  
inches using Roto-hammer into concrete slab  
and secure the 8 pieces (10 pieces for MM63) of  
12" long rebar with epoxy. See Figure 34 & 35.

3) Align Right Side Hearth to the outline created. The  
overall width should allow for an approximate gap of  
1/8" between slabs for the additional mortar to unite  
the remaining slab. Check for surface flatness, level  
if necessary.

4) Repeat step 3 for Left Side Hearth.  
5) Before installing side walls, confirm placement of  
outside air kit (if required). This can be installed ei-  
ther side depending on which side is accessible to  
outside combustion air (all diagrams in this manual  
show the combustion air inlet hole on the right side).

amount of mortar. Remember that you have the op-  
tion of using shims but they must be removed and  
any holes filled. Make any adjustments to the fire-  
place alignment before continuing to the next step.  
NOTE: The chimney hole on the Dome Top is not

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 alter-  
nate, it must be sized to 50% of the hearth maximum.

tions included with doors.  
Cleaning Glass  
Glass doors are optional with the fireplace. When  
fireplace is in operation, doors must be fully opened  
or fully closed position only or a fire hazard may be  
created (see Figure 49).  
A fireplace equipped with glass doors operates much  
differently than a fireplace with an open front. A fire-  
place with glass doors has a limited amount of air for  
combustion.  
Clean glass with any commercial glass cleaner or  
soap and water. Do not use any abrasive material to  
clean glass. Do not clean glass with any cool water if  
glass is still hot from the fire and smoke.  
oWneR’s oPeRaTIon & PReCaUTIons  
WaRnInG: do not attempt to operate your  
Excessive heat within the fireplace can result if too  
large a fire is built or if combustion air gate is not  
completely open. The following tips should be fol-  
lowed to assure that both the fireplace and glass door  
retain their beauty and function properly. Both the flue  
damper and glass doors must be fully opened before  
starting fire. This will provide sufficient combustion air  
and maintain safe temperatures in firebox.  
IMPORTANT: The glass must be allowed to warm  
slowly and evenly. The tempered glass will withstand a  
gradual temperature rise to 375 °F, without sustaining  
any damage. Termperatures as high as this or higher  
are not likely to occur with normal use. Such materials  
as pitch/wax laden logs, very dry mill end lumber and  
large amounts of paper or cardboard boxes can create  
an excessively hot fire and should not be burned in  
this fireplace. Always keep the fire well back from the  
doors and never allow flames to contact the glass.

CaUTIon: The manufacturer cautions  
againstusingchemicalchimneycleaners.never  
use charcoal or coal in the fireplace under any  
circumstances.  
First Lighting of the Grand Meridian – After con-  
struction is completed, all elements of the fire-  
place and chimney system must be complete-  
ly dry. This means that the unit must stand  
without any firing for a minimum of 28 days.  
Only after that period of time can a first lighting take  
place. The first fire must be small and well-controlled,  
started with a small amount of kindling. Add no more  
than eight pounds of wood, preferably small logs  
not more than 3” (three inches) in diameter. You will  
probably burn no more than three to four of these  
small logs. Do not let the fire burn for more than one  
hour. After this first lighting – when the fireplace has  
started to “cure” Do not set another fire for at least  
24 hours.

Second Lighting – Start the fire slowly and gradually kindling, then the softer wood and finally, the harder  
as you did with the first lighting, but this time you can wood logs. As the fire burns, you can carefully lay ad-  
burn up to ten pounds of firewood, probably four to ditional logs on the flame, but make sure you place  
five logs that are 3" in diameter. With the second light- them gently without forcing them into the opening.

has been properly cured with 1st and 2nd lighting,  
you will be able to add a full fuel load to the fire-  
place which is about 10 to 15 pounds of firewood at  
any given time. Consider that this typical fuel load is  
three to four dry hardwood logs that are about 6" ) to  
8" in diameter.  
The manufacturer recommends that inspection of  
the fireplace and chimney take place on a monthly  
basis during the heating season. Start at the top,  
looking for birds’ nests, leaves or any other obstruc-  
tions. Also check the spark arrestor, for creosote or  
soot build-up. Twice a year, you will want to clean the  
firebox and chimney yourself or hire a professional  
chimney sweep to do the job for you. If you elect to  
do it yourself, use a plastic, wood or steel brush for  
the inside of the chimney.  
Without a grate for your firewood to rest on, you can-  
not get the air flow you need under the fire which  
makes for a hotter, more satisfying fire.  
Do not “over burn” – Always remember, your Grand  
Meridianreplaceisanelegantadditiontoyourhome.  
It is not an indoor incinerator! If you start to use the  
fireplace and begin a routine of “over burning,” you  
can permanently and unalterably damage the unit.  
Under no circumstances should you be burning  
household trash, including chemicals and combus-  
tibles, cardboard boxes, your office papers, scrap  
lumber or stray branches from your yard, particularly  
pine.  
For the spark arrestor, scrub with a wire brush. To  
dismantle the chimney cap for cleaning of the flue,  
unscrew the four screws that hold it in place. For  
cleaning access from below, open the damper in the  
firebox. It is best to use a flexible handle chimney  
cleaning brush made especially for the job.  
WaRnInG: Burning of above mentioned  
materials will cause an unsafe condition and  
will void your warranty!  
If your fireplace system has any offset chimney sec-  
tions, start cleaning with the flexible brush from the  
top of the section downward to the elbow. Then clean  
from the firebox up to the offset/return section.  
sTaRTInG a FIRe and BasIC oPeRaTIon  
Be sure that you have covered the floor of the fire-  
place and out to the hearth with a damp sheet that  
has been taped securely in place. When all the soot  
has settled, remove the sheet and vacuum up – don’t  
sweep the excess soot.  
Before starting a fire in your fireplace, open the damp-  
er to its’ fully open position. Crumple some paper and  
place it on the log grate. Use some soft, dry wood as  
kindling and put it on top of the paper. Place some  
small logs or split logs atop the paper and kindling.  
Good old-fashioned “elbow grease” is enough to re-  
move the extraneous matter from the inside of the  
firebox and chimney. Never use any chemical clean-  
ers as their residue could introduce a fire hazard af-  
ter the task is completed.  
Finish off the fuel load with a couple of hardwood  
logs or split logs – oak or hickory. Check to see that  
you’re stacking the logs so that they will fall inside  
the grate as they burn.  
To get the most out of your wood, it is recommend-  
ed that you let it set and completely dry out for nine  
months to a year.  
Outside Inspection – During your once a month in-  
spection of the firebox and chimney, make it a point  
to also check the outside of the chimney, the metal

and creosote build-up, it is recommended that the  
fireplace and chimney cleaning be done twice a year.  
In colder climates, cleaning should be done more of-  
ten.  
The Grand Meridian fireplaces are manufactured us-  
ing high quality materials. During the drying process,  
surface cracking may occur. These small cracks (un-  
der 1/16” will not effect the fireplace safety or per-  
formance). During the assembly process, fill surface  
cracks with thin-set mortar and brush when drying for  
a smooth surface finish.  
Always allow the fireplace to completely cool before  
you work on it, which means, of course, shutting off  
all gas and electrical connections, also.  
Be certain that you use only solid fuel in your fire-  
place. You may use a natural or LP gas log lighter as  
a method to start your wood fire.  
The flue damper must be in the OPEN position when-  
ever there is heat in the fireplace.
