Location

Note: You may need to provide combustion and ventilation air
from an outside source to adequately satisfy local codes so
avoid installing a combustion air inlet where the opening could
be blocked by snow, bushes or other obstacles. Note that the
access for outside air inlet is located on the right hand side of
the fireplace.

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-free heaters add moisture to the air.
Installing a 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-out the 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 the sub-flooring framing.
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.
