FIGURE 1 MINIMUM CLEARANCES TO COMBUSTIBLES* - Table 1 lists values
*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 90F° (50C°) above room temperature.
NOTE: A ‘PEEL & STICK’ SIGN IS SUPPLIED: USE AN INDELIBLE MARKER TO
ENTER VALUES ON THE SIGN: ‘H’ = Calculate (instruction below)
Sides of horizontal heater: ‘S’ = 24 inches (61 cm)
