PRODUCT OVERVIEW
The Grand Meridian Fireplaces are designed as
factory-built blocks to be assembled on-site. These
replaces may be installed on either combustible or
non-combustible oors. In order for the replace to
be installed on a combustible oor though, it is nec-
essary that the replace be supported on a platform
or sub-oor that is non-combustible.
The Four Components of the Grand Meridian
Fireplace:
• Combustible or Non-Combustible Floor
• Non-Combustible Raised Platform
• Firebox and Smoke Dome
• IHP chimney system required.
IMPORTANT: Follow the chimney pipe
manufacturer’s instructions on the installation of
their specic ue system.
Careful step-by-step instructions for each phase of
the installation procedure will be given for the Grand
Meridian conventional radiant heat replaces.
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 oor on which it rests.
• Chimney system measurements.
• Choice of materials and craftsmanship in replace
and hearth nishing.

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 specied mini-
mum clearances to combustibles.
Testing and listing for these Grand Meridian Fireplac-
es has been undertaken by the PFS Corporation.
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
IHP Fireplace is designed for installation per the
National Fire Protection Association Standard
f o r C h i m n e y s , F i r e p l a c e s , V e n t s a n d S o l i d
Fuel-Burning Appliances (NFPA211).
When choosing the location of your IHP Fireplace,
keep in mind you must maintain 2" minimum clearance
from left, right and rear of Fireplace to surrounding
structure. Also, when choosing a location, consider
outside air requirements to determine if it will be on
the left or right side of the Fireplace. In the case of
an island installation, outside air accessibility may be
obtained through sub ooring, see Optional Outside
Air Kit on page 12.

PRE-INSTALLATION PREPARATION
WARNING: Do not pack required air spaces
with insulation or other materials.
Minimum/Maximum Chimney Height for
Residential Installation
Minimum height of chimney, measured from base of
replace to ue gas outlet of termination, is 14 feet
for straight ue or 17 feet for a ue 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 replace, chimney sections
and height of termination assembly at level of the
ue gas outlet (see Figure 20, page 16).
FRAMING
1. Frame opening for replace using dimensions shown
in Figures 6 and 7.
2. If replace is to be installed directly on carpeting,
tile (other than ceramic) or any combustible material
other than wood ooring, replace must be installed
upon a metal extending full width and depth of re-
place.
3. Set replace directly in front of this opening and
slide unit back until nailing anges touch side fram-
ing.
4. Check level of the replace and shim with sheet
metal if necessary.
5. Before securing replace to prepared framing,
ember protector (provided) must be placed between
hearth extension (not supplied) and under bottom
front edge of replace to protect against glowing em-
bers falling through. If replace is to be installed on
a raised platform, a Z-type ember protector (not sup-
plied) must be fabricated to t your required platform
height. Ember protector should extend under replace
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 replace to framing
through anges located on sides of replace.
SELECTING LOCATION
To determine the safest and most efcient location
for the replace, 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 replace 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 replace
(see Optional Outside Air Kit on page 12).
MINIMUM CLEARANCE TO COMBUSTIBLES
The distance to be maintained from the surfaces
of the replace to combustibles must be observed.
Below is a list of the most common combustible
materials to name a few:
Drywall Wood Flooring Plywood
Sub-Flooring Wood Framing Mill Board

ATTENTION: You will note that there will be a gap
between the replace front and the extension of the
non-combustible hearth material. Be certain that
you seal this with non-combustible material.
These Grand Meridian Fireplaces have been
designed with clearance to combustible oors as
indicated in Page 8. Cover any part of the combustible
oor system left exposed with 1” (one inch) thick
ceramic ber insulation rated up to 2,100° F.
ATTENTION: It is critical to abide by the clearances
listed in this manual for all components specied as
it allows for movement of hot air from the fireplace
into interior areas of the chimney chase. Also, be cer-
tain 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 replace installation.
NOTE: It is required that ember protector strips must
be laid on the ber of the non-combustible raised plat-
form (see Figure 10). These are included with the
Metal Base accessory.
WARNING: Hearth extension is to be installed
only as shown in Figure 10.

MANTEL AND MANTEL SHELF CLEARANCES
As with any radiant heat replace, the Grand Merid-
ian replaces 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 replace cannot be installed
closer than 2 ft. to any walls in the room the replace
is housed in or to any walls of adjoining rooms.
Caution in Regards to Combustibles – If any part of
the replace or objects in the room (curtains, rugs,
paint, cushions, etc.) start to show warping or dis-
coloration due to heat from the replace, it is time to
take immediate action. Do not use the replace until
you have gured out how to address the problem.
You are facing a potential re hazard. IHP cannot be
responsible for the make-up of material on the exte-
rior of the replace you have chosen, nor can IHP 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 airow or the modications to
the room itself.
HEARTH EXTENSION
Where the ooring material at the opening of the
replace is combustible, it is required that the
hearth extension be covered with a non-combustible
material. All hearth extensions must be made of
code-rated, non-combustible materials such as tile,
brick, marble, concrete or stone. The extension
should be set ush against the front of the replace
front and measure 20" minimum at the front and 12"
minimum beyond the sides of the replace opening
as shown in 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-combustible material and
any material under the structure must also be non-
combustible.
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).

FACTORY BUILT CHIMNEY SYSTEMS
1) The Grand Meridian is designed to be installed
with IHP Metal Chimney System.
2) This Grand Meridian replace is intended as a
supplemental heat source only. It is not intended
as a primary heat source.
3) It is the responsibility of the contractor/installer
(not the manufacturer) to ensure that adequate
combustion air is provided for proper function of
this replace. Fireplaces take up a large volume of
replacement air from outside the house and if the
house is of airtight construction, smoke spillage
may occur if proper draft is not achieved.
4) There are many conditions beyond the
manufacturer’s control regarding improper replace
operation. The manufacturer cannot ensure
“smoke free” operation, nor can the manufacturer
take on the responsibility for problems with
surrounding construction; chimneys that have not

OPTIONAL OUTSIDE AIR KIT (MODEL MM4AK)
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 ue 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 specic
requirements.
The installation of an outside air kit should be per-
formed during the rough framing of the replace 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.
Install Combustion Air Kit into the rebox through the
side wall opening provided. A 4" dia. hole will also be
required through the rebrick side lining (see Figure
12). The tubing that goes out of the rebox wall must
feed into a exible metal conduit as the source for
outside combustible air. Install a screened termina-
tion cap to keep out small animals.

been built at the correct heights; system drafts
caused by faulty mechanical systems; adverse
weather conditions or any other environmental
situations over which the manufacturer has no
control.
5) Inspect all replace & chimney components for
evidence of damage prior to starting installation.
Consult your local distributor for replacement
parts if necessary.
6) Under no circumstances should you make any
adjustments or modications to the chimney
system during the installation procedure. If
you do, you are not only liable for negating the
warranty, but you could very well cause a serious
malfunction of the replace. You must follow these
chimney instructions.
7) Caution is urged if it is decided to add insulation
material to any part of the Grand Meridian Fireplace
or Chimney system, be certain that the insulation
material is kept at least 2” away from any part of
the system. When using insulation or vapor barrier
materials, cover with a layer of plywood, particle
board or gypsum board to maintain the specied
2” clearance.
8) Air spaces around rebox must remain open.
DO NOT ll these open spaces with insulation or
packing material of any kind.
CHIMNEY PIPE
The IHP chimney system consists of 12", 18", 24",
36" and 48" snap-lock, double-wall pipe segments,
planned for maximum adaptability to individual site re-
quirements. Actual lengths gained after tting overlaps
must be taken into consideration (lineal gain) and are
given in the lineal gain chart (see Figure 14). Lineal
Gain is the actual measurable length of a part after
two or more parts are connected.
WARNING: The opening in the collar around
the chimney at the top of the replace must not
be obstructed. Never use blown insulation to
ll the chimney enclosure.

ASSEMBLY AND INSTALLATION OF DOUBLE
WALL CHIMNEY SYSTEM
Each double wall chimney section consists of a gal-
vanized outer pipe, a stainless steel inner ue pipe
and a wire spacer. The pipe sections must be as-
sembled independently as the chimney is installed.
When connecting chimney directly to the replace,
the inner ue pipe section must be installed rst
with the lanced side up. The outer pipe section can
then be installed over the ue pipe section with the
hemmed end up. Press down on each pipe section
until the lances securely engage the hem on the re-
place starter. The wire will assure the proper spacing
between the inner and outer pipe sections.
Continue to assemble chimney sections as outlined
above, making sure that both the inner and outer
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).

USING ELBOW OFFSETS (30E-12DM)
1. To achieve desired offset, you may install combi-
nations of 12”, 18”, 24”, 36” and 48” length of double
wall pipe (see offset chart and Figure 15).
2. Chimney weight above offset rests on return elbow.
Straps must be securely nailed to rafters or joists (see
Figure 16, details A and B).
3. Maximum length of pipe between supports (re-
turn elbow or 12S-12DM) is 6’ of angle run. Maxi-
mum of two 6’ angle run sections per chimney sys-
tem (see Figure 17, page 16).
4. All pipe connections between the offset and re-
turn must be secured with two screws on the outer
pipe only (see Figure 15). Do not penetrate the in-
ner stainless.

FIRESTOP SPACERS (FS-10)
Firestop spacers are required at each point where the
chimney penetrates a oor 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 restop must be placed onto the ceil-
ing from below as shown in Figure 18.
They also provide complete separation from one oor
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 restop must be
placed into an attic oor as shown in Figure 19.

PENETRATING ROOF
To maintain a 2" clearance to the pipe on a roof with
a pitch, a rectangular opening must be cut.
1. Determine center point through which pipe will
penetrate roof.
2. Determine center point of roof. Pitch is distance
the roof drops over a given span, usually 12". A 6/12
pitch means that roof drops 6" for each 12" measured
horizontally down from roof rafters.
3. Use roof opening chart (Figure 20) to determine
correct opening length and ashing required.
4. Remove shingles around opening measured. Cut
out this section.
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.

FLASHING INSTALLATION (V6F-10DM OR
V12F-10DM)
Determine the ashing to be used with the roof open-
ing chart. Slide ashing over pipe until base is at
against roof. Replace as many shingles as needed
to cover exposed area and ashing base. Secure in
position by nailing through shingles (see Figure 21).
DO NOT NAIL THROUGH FLASHING CONE.
Installing Flashing on a Metal Roof
When installing the ashing on a metal roof, it is re-
quired that putty tape be used between the ashing
and the roof. The ashing 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 ashing to provide a proper seal.
Storm Collar Installation (SC2-1)
Place storm collar over pipe and slide down until it is
snug against the open edge of the ashing (see Figure
22). Apply waterproof caulk around the perimeter of
the collar to provide a proper seal.

CHASE INSTALLATIONS
Instructions for chase installations are included with
the chase style termination chosen. In a multiple
chase installation, be sure to provide adequate dis-
tance between terminations to prevent smoke spill-
age from one termination to another. We suggest
that terminations be separated at least 24", center to
center and stacked at a vertical height difference of
18" (see Figure 24, page 17).

10 FOOT RULE
All ue gas outlet chimney terminations must extend
a minimum of 3 feet in height above the highest point
where it passes through the roof and must be at least
2 feet above the highest point of the roof that is within
a horizontal distance of 10 feet (see Figure 25).
FINISHING FIREPLACE
Combustible materials, such as wallboard, gypsum
board, sheet rock, drywall, plywood, etc. may not
make direct contact with sides and top around the re-
place face. See clearance requirements in Figures 8
and 9 on page 9. It is important that combustible ma-
terials do not overlap the face itself. Brick, glass, tile or
other noncombustible materials may overlap the front
face provided they do not obstruct essential openings.
When overlapping with a noncombustible facing ma-
terial, use only noncombustible mortar or adhesive.
MASONRY (PRECAST) CHIMNEY

OPTIONAL GAS LINE INSTALLATION
You may elect to add a vented decorative gas appli-
ance (gas log) to your Grand Meridian Fireplace. If
so, follow the installation instructions from the Deco-
rative Gas Appliance manufacturer. Familiarize your-
self with requirements for installation as outlined by
the National Fuel Gas Code, ANSI Z223.1/NFPA 54.
This gas pipe provision should only be used on a
decorative gas appliance.
You can route the gas piping practically anywhere in
the rebox – the oor, back wall or side walls. You
will just need a masonry drill; the instructions from
the gas appliance manufacturer will be very straight-
forward.
Fill in the holes you have drilled around the gas pip-
ing with the regular mortar.
Follow the Gas Log manufacturer’s instructions.
OPTIONAL ELECTRICAL CONNECTION INSTALLATION
Like the gas line, electrical feed lines can be run
through the oor, back wall, or side walls. Follow
local building and electrical code requirements.

www.Astria.US.com 125160-01B18
SUPPORTING FLOOR SYSTEM INSTALLATION
It is the ultimate responsibility of the installer to en-
sure that proper concrete slab supports are used.
WARNING to the licensed design professional
and/orbuildingcontractor:Itisyourresponsibility
to be certain that the Grand Meridian can be
properly supported by the combustible oor
system on which the replace will rest.
For replace support foundations installed on con-
crete refer to Appendix I and II (pages 42 & 43) for
specic instructions.
REBAR LOCATIONS
Lay-out the position of the replace 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 instruc-
tions for installation of rebar into slab.
WOOD FLOOR
Anchorage of replace to wood oor construction is
required. Refer to Figure 29 on page 20 for anchor-
age dimensions. Four anchors are required to attach
to the sub-ooring framing.
CRAWL SPACE OR UPPER FLOOR:
For installation of rebox over combustible crawl
spaces or upper oors, anchorage of the rebox is
required. Illustrations of examples of possible an-
chorage methods are shown in Figures 26 thru 28
depending upon the type of oor framing. Final meth-
od of anchorage is to be determined by licensed de-
sign professional.
For conventional framing, where the oor joists are
parallel with the sides of the rebox, the addition of
oor joists to align with the anchor brackets allows the
brackets to be directly connected to the oor joists.
NOTE: Additional oor joists may be required to sup-
port the weight of the rebox and chimney. Where
the oor joists run parallel to the front of the rebox,
anchorage can be accomplished in like manner as
shown in Figure 26 using blocking between the oor
joist.
For oors supported by I-Joists, the method of an-
chorage is illustrated in Figures 27 and 28, page 19.
Figure 31, page 20 illustrates the general arrange-
ment of anchorage to oor 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 oor framing. Additional oor joists or I-joists
may be required as determined by the licensed de-
sign professional.
The dead weights for the replace are noted in Table
I. It is the task and responsibility of the general con-
tractor/installer to see that the proper reinforcement
for weight loads are made by a licensed design pro-
fessional prior to the replace installation.
As stated above, it is desirable to place additional
framing for alignment of anchor rods. Refer to Figure
29, page 20 for anchor rod locations.
Attach the rebox side wall anchors to steel sup-
port frame by inserting all-thread rods through holes
on the bottom ange on the steel support frame as
shown in Figure 32 and 33, page 21. Secure with
two Ø 2" o.d. x Ø 9/16" i.d. x 0.10" Washers and two
1/2"-13 UNC Nuts.

8"METAL BASE (MMB63)
The Metal Base (MMB63) ensures the minimum
8"clearance above combustible ooring is main-
tained with Grand Meridian Model MM63.
A layer of 1/2" minimum Cement Board (Not Includ-
ed) is required on the top and mid section below as
shown in Figure 32, page 21. The required sizes are
shown in the table below.
IMPORTANT: Remember to tighten up nuts below
the oor after replace installation in order to take up
any slack in the threads.
EMBER PROTECTOR STRIPS:
Ember protector strips (included with Metal Base
Kit) are required between the front of the Fireplace
Hearth and Hearth Extension. A minimum thickness
of 26 gauge metal strip at least 4" wide can be used.
The length needs to extend 2 inches beyond each
side of the replace opening. If two strips are used,
make sure they overlap at least two inches in the
middle. The strip is placed about 2" into the under-
side of the platform at the front (Figure 10, page 10).
NOTE: When using an on-site constructed hearth ex-
tension, you may use a sand-cement grout between
the hearth and extension instead.
