NOTE: The clearances specifi ed above must be maintained to combustibles and other materials that may be damaged by
temperatures 90°F above ambient temperature. It is the installer’s responsibility to ensure that building materials with a low heat
tolerance which may degrade at lower temperatures are protected to prevent degradation. Clearances to combustibles are posted
on the refl ector near the control end of the heater. In locations used for storage of combustible materials where they may be stacked
below the heater, NFPA 54 requires that the installer must post signs that will “specify the maximum permissible stacking height to
maintain the required clearances from the heater to combustibles.” Manufacturer recommends posting these signs adjacent to the
heater thermostat or other suitable location that will provide enhanced visibility.
