CAUTION: Combustion air inlet ducts shall not
terminate in attic space.
The maximum height for the air vent can not exceed
3 feet below the flue gas outlet of the termination.
FACTORY BUILT CHIMNEY SYSTEMS
1) The Grand Meridian is designed to be installed with IHP Metal
Chimney System.
2) This Grand Meridian fireplace 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 fireplace. 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 fireplace 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 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 fireplace & chimney components for evidence
of damage prior to starting installation. Consult your local
distributor for replacement parts if necessary.

OPTIONAL OUTSIDE AIR KIT (MODEL MM4AK)
The Grand Meridian Fireplace needs enough replacement air to
function properly and some local building codes may require out-
side combustion air to be provided. If no replacement air is pro-
vided, 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 installation of an outside air kit should be performed 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 13a). 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 intake. You don’t want a place where
snow will collect, where bushes or trees will be growing or a loca-
tion that is too close to any other structure.
Install Combustion Air Kit into the firebox through the side wall
opening provided. A 4" dia. hole will also be required through the
firebrick side lining (see Figure 13). The tubing that goes out of the
firebox wall must feed into a flexible metal conduit as the source for
outside combustible air. Install a screened termination cap to keep
out small animals.
