Steffes 6140 - Manual (Page 11)

PLACEMENT AND CLEARANCE REQUIREMENTS
The physical dimensions of the system, along with the clearances
required, MUST be taken into consideration when choosing its
location within a structure. (See Figures 2 and 3 for Clearance
Requirements and System Dimensions.)
The best installation location for this system is in a space requir-
ing heat so some amount of the heating requirements can be
satisfied through static dissipation from the warm outer panels.
In situations where the system is not installed in an area it is
intended to heat (i.e. storage room), it is important to account for
the heat lost through static dissipation by making proper adjust-
ments when sizing the system.
The minimum area required for the installation of the
system is 100 square feet. This area must remain free of
debris and room air should be maintained at less than 85 o
Fahrenheit. If the system is being installed in an area with less
than 400 square feet, ventilation MUST be provided. To venti-
late, a minimum of a 24” X 24” opening must be installed, if not
already present, into the area where the furnace is located. In
addition, a 6” X 6” non-closing type register must be cut into the
return air duct of the furnace to minimize heat build-up in the
room. This register must be installed in a manner that ensures the air drawn into the furnace passes through the
filter first (See Figure 2).
In addition to the physical space requirements, the weight of the system must also be taken into consideration
when selecting the installation surface. A level concrete floor is the best installation surface on which to place the
system, but most well supported surfaces are acceptable. If unsure of floor load capacity, consult a building
contractor or architect.
Special requirements must be considered if placing the system in a garage or other area where
combustible vapors may be present. Consult local, state, and national codes and regulations to
ensure proper installation. An 18" stand (Order Item #1301585) is available to elevate the
system.

Risk of fire. Can cause injury or death.
w Violation of the clearance require-
ments and/or failure to provide proper
ventilation can cause improper opera-
tion of the system. Maintain the
placement and clearance require-
ments as specified and provide venti-
lation as necessary.
w Failure to maintain room temperature
in the mechanical room of 85 o F or less
may result in equipment damage.
Thermostatically controlled ventilation
should be provided if the temperature
in this area exceeds 85 o F.
w Moving the system after install may
result in equipment damage. Do NOT
move system from original installed
location.
