*The clearance to combustible materials represents the minimum distance that must be main-
tained between the heater and a nearby surface. The stated clearance to combustibles
represents a surface temperature of 117F° (65C°) above room temperature.
It is the installer's responsibility to ensure that building materials with a low heat toler-
ance which may degrade at lower temperatures are protected to prevent degradation.
Examples of low heat tolerance materials include vinyl siding, fabrics, some plastics,
filmy materials, some coatings and laminated finishes, etc.

53 inches (135 cm) is the required minimum clearance below the heater ('C')
•
'T' is measured on site = distance from the bottom of the heater hanger to the floor
•
H = T- 53 inches (135 cm): Do not stack or store higher than 'H' under the heater
