Venting Installation
Optional Outside air Kit (Model MM4AK)
The Grand Meridian Fireplace needs enough replacement 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, 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 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 firebox through the side wall opening provided. A 4" dia. hole will also be required through the firebrick side lining (see Figure 12). 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.

Factory built chimney systems
1)The Grand Meridian is designed to be installed with FMI PRODUCTS, LLC 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’scontrolregardingimproperfireplace 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
