WARNING
Avoid Serious Injury, Death, or Property Damage.
Maintain Clearances to Combustible to Prevent the Risk of Fire.
Clearances to combustibles must be maintained at
all times in order to prevent the ignition of
combustible materials. 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. Signs must either be posted adjacent to the
heater's thermostats or, in the absence of such thermostats, in a
conspicuous location. Clearances are provided on the heater's
safety label and in the heater's Installation, Operation, and
Maintenance manual. Product installation and operation must
comply with applicable standards, codes, and regulations. Post
this tag adjacent to the heater's thermostat or controls before
operating the heater.
