PLACEMENT
The physical dimensions of the furnace along with the clearances required must be taken into consideration
when choosing a location for the furnace. The minimum area needed for the installation of a furnace is 100
square feet. The best installation location for the furnace is in an area it will be heating. Although most of the
heating requirements of the space will be satisfied by the heat delivered through the duct system, a small amount
of the heating requirements will also be satisfied through static heat dissipating through the furnace's warm
outside panels. In situations where the furnace will not be installed in the area it is intended to heat (i.e. garage),
it is important to account for the heat lost through its panels by making proper adjustments in sizing of the
furnace.
In addition to the physical space requirements, the weight of the furnace must also be taken into consideration
when selecting the installation surface. A level concrete floor is the best surface on which to place the furnace,
but most well supported surfaces are acceptable. If in doubt about floor load capacity, consult a building con
tractor or architect. (See Figure 2 for furnace and ducting dimensions.)
