The clearance to combustible materials represents the minimum distance that must be
maintained between the heater and a nearby surface.
The stated clearance to combustible materials represents the minimum distance that
must be maintained between the outer heater surface and a nearby surface. The stated
clearance to combustibles represents a surface temperature of 90 degree Fahrenheit
(32 degrees Celsius) above room temperature. Building material with a low heat
tolerance (such as plastics, vinyl siding, canvas, tri-ply, filmy materials, fabrics, etc.)
may be subject to degradation at lower temperatures. It is the installer’s responsibility to
assure that adjacent material are not subject to degradation.
In a parking structure, a sign with a warning statement
that an overhead heater is
present should be installed in a visible location. Minimum required clearances below the
heater should be clearly visible so that appropriate distances to combustibles will be
maintained to vehicles.
In locations used for the storage of combustible materials, signs must be posted to
specify the maximum permissible stacking height to maintain the required clearances
from the heater to the combustibles, and that such signs must either be posted adjacent
to the heater thermostats or in the absence of such thermostats in a conspicuous
location. For your convenience a sign is provided with these instructions. (A sample
stacked combustibles warning sign is included in the last page of this manual). See
information on “maximum stack height under appliance”.
In addition to stored or stationary material, consideration must also be given to
moveable objects such as cranes, vehicles, and overhead doors, and structural objects
that may have their own specified minimum clearances to heat sources, such as
sprinkler heads, electrical and gas lines, and electrical fixtures.
Minimum clearances (cm and inches) from combustibles are measured from the radiant
surface.
Clearances are reduced by 1/3, 15 ft (4.6 m) from the burner.
