WARNING:
FIRE OR EXPLOSION HAZARD
CAN CAUSE PROPERTY DAMAGE, SEVERE INJURY OR DEATH.
In all situations, clearances to combustibles must be maintained. Failure to observe clearances to combustibles may result in property
damage, severe injury, or death.
Minimum clearances must be maintained from vehicles parked below the heater. Signs should be posted in storage areas to specify
maximum stacking height to maintain required clearances to combustibles.
Caution should be used when running the system near combustible materials such as wood, paper, rubber, etc. Consideration should be
given to partitions, storage racks, hoists, building construction, etc.
TABLE 1 gives minimum acceptable clearances to combustibles. Clearances as shown in TABLE 1 are not for use in four-sided enclosures.
