*MINIMUM CLEARANCES

 specified in these tables must be maintained to combustible and other materials which may be

damaged by temperatures 90°F above (50°C above) ambient room temperature.  Minimum clearances to combustibles are
also specified on each heater’s serial plate.  According to the National Fuel Gas Code (NFPA 54), “in locations used for the
storage of combustible materials, signs must be posted to specify the maximum permissible stacking height to maintain
required clearances from the heater to the combustibles.”  Gas supply lines, electrical supply lines, or sprinkler heads shall
not be located within the minimum clearances to combustibles indicated above.

NOTE

:  Carefully  examine surrounding materials near the heater.  Materials, such as plastic, having low service

temperature ratings can be discolored or damaged.
