Unit must be installed so that clearances are provided for combustion air space, ser-
vice and inspection, and for proper spacing from combustible construction. Clearance
to combustibles is defined as the minimum distance from the heater to a surface or
object that is necessary to ensure that a surface temperature of 90°F above the sur-
rounding ambient temperature is not exceeded. See table on top of page 8.
4.2 Clearances
NOTE: See FIGURES 5
and 7 for illustrations of
service clearances.
