Fireplace Location
Fireplace location reflects the objectives and preferences
of the homeowner. For ease of monitoring and refueling as well as for
aesthetic enjoyment, woodburning fireplaces are ideally placed in frequently
used areas such as the living room, family room, or den. Selection of
location for factory-built fireplaces and wood stoves varies enough
to warrant separate consideration.
Fireplace Location
It's light weight and close clearance to combustibles
capability makes the factory-built fireplace an extremely versatile
hearth product. Because of their relatively small framing dimensions,
factory-built fireplaces may be placed in corners, against interior
and exterior walls, used as room dividers, or installed in field-constructed
chases on the exterior of a dwelling.
Additionally, factory-built fireplaces do not require
special footings and foundations because they generally weigh no more
than a large piece of furniture. Sufficient care should be taken, however,
to make sure that floor joints and/or the foundation for the fireplace
are strong enough to support the fireplace system without sagging for
the expected life cycle of the building in which it is placed. In spite
of the many installation conveniences of factory-built fireplaces, there
are factors that affect safety, performance, and installation cost that
should be considered.
Firebox Location
The fireplace should not be located near frequently opened
doors, central heat furnace outlet registers or cold air returns or
in any area where turbulence or negative pressure effects will create
air movement that will cause smoke spillage, or allow flames, sparks,
or ashes to escape the fireplace opening. Do not place the fireplace
directly across from, or in an area where its heat output will affect
central heating thermostats.
Location of the fireplace and chimney can also affect
proper performance of the system. The chimney should be located so that
it is as vertically straight as possible for maximum draft (and cost
reduction). An interior location offers better draft performance than
an exterior chimney location due to reduced heat loss from the chimney.
The chimney should not terminate under overhanging trees or other obstructions
that might create air turbulence that could reduce draft.
Construction Features
The location selected should require minimal cutting of
joists and rafters and limited alteration of the dwelling structure.
Engineered trusses should not be cut or altered.
Safe Clearances
Installation planning details include making sure clearances
can be met or exceeded. Minimum clearances between the firebox and framing,
sheetrock, and other combustibles must be maintained. The same it true
for the area surrounding the chimney and for its penetration of walls,
ceilings, floors, and roofs.
The fireplace should also be located so that appropriate
minimum clearances between the fireplace and adjacent walls and other
combustibles (such as drapes and furniture) will be maintained. Consult
the manufacturer's instructions for this specification. This spacing
is required to prevent hazardous over-heating of combustible materials
by heat radiated from the fireplace opening. Some manufacturers offer
shielding accessories or recommend materials that allow their fireplaces
to be installed at reduced clearances. These reduced clearances are
normally included in the manufacturer's installation instructions.
Check manufacturer's instructions for any requirements
for the minimum size of the room for installation. It should not be
located in an area where fallible liquids or gases will be stored.
