Selecting the Location of Your Fireplace
To determine the best location for your fireplace, take into consideration the location of windows, doors, adjacent side
walls and the general traffic flow pattern of the room, allowing space in front of the fireplace for a hearth extension and
mantle. Hot air ducts, heat circulation ability of the unit and ducting ability for combustion air must also be considered
when selecting the location. If possible, you should select a location that does not require cutting floor joists or rafters.
In most cases no additional floor support is needed for the fireplace and facing system weight. Consult your local building
code requirements or a structural engineer to determine if additional support is needed.
If possible, install the fireplace and chimney on the interior of the structure as it will provide better draft performance. In
areas that experience below 0° Fahrenheit temperatures, the use of an exterior chimney increases the possibility of poor
draft, increased creosote formation and slow starting of the fire. Installations which are located low in the house such as the
basement, in combination with an outside chimney, are especially prone to flow reversal on start up.
Hearth Extension Requirements
The GranView can be installed on a raised hearth provided there is a minimum of 72” measured between the fireplace
base and finished ceiling for front louver heat venting or 80” if using dual or single top vent ducting of heated air. Raised
hearths must extend 16” in front of and 8” to each side of the fireplace opening. Floor level hearths may have a minimum
of a 16” noncombustible protrusion, but 20” is recommended for extra spark protection along with the 8” side protection.
Installations using the single door option should have noncombustible materials extend out past the foremost swing of the
door whether it is a combination of raised and floor level material or not. This will contain any hot embers that may ride on
the inner channel of the door assembly as it opens.
Cover all combustibles under the hearth area 16” in front of and 2 1/2” to each side of the fireplace with the 48” x
16” Micore provided. This provides thermal protection for the combustibles.
Any area outside of this space can have
the hearth materials in direct contact with combustibles.
A spark guard (2-L shaped metal strips) are provided to create spark protection where the hearth framing meets the
fireplace front. These pieces are 2 1/2” x 1 1/2” x 48” and are designed to create a barrier for sparks that may penetrate the
hearth to the framing below. The spark guard must be placed 2 1/2” under the fireplace base and extend 2 1/2” forward under
the hearth stone. When installing this 2 piece guard, place the first section on top of the protruding hearth. Next, slide the
second section under the fireplace, overlapping the vertical return of the lower section. If this unit is installed on a non-
combustible base with no combustibles below the hearth, no spark guard is needed.
The room air inlet vent at the base
of the fireplace must not be obstructed by any hearth material abutting the unit.
