FIRST, verify that the kit received is the appropriate one for the installation. Check the
heater size and the CFM.
SECOND, where the filter cabinet is going to be attached to the heater, find four
embosses in the metal panel. For rear attachment, see FIGURE 6B; for side attach-
ment, see FIGURE 6A. These embosses are corner indicators for the inlet air open-
ing. Using tin snips or aviation shears, carefully cut straight lines between the corner
marks until the opening is created.
CAUTION: The cut edges of the metal cabinet will be sharp.
THIRD, refer to the illustration in FIGURE 7. Drill the required 1/8" holes in the side or
rear of the heater cabinet where the filter cabinet is being installed.
