FOR 80% DOWNFLOW FURNACE
The PCB transformer can be assembled to the furnace partition
plate. Fasten the PCB transformer using (2) field supplied self-
drilling screws. Locate the transformer to the partition plate to
the recommended location. See Figure 21. The transformer should
be parallel to the edge of the heat shield. Self-drilling screws should
be no longer than 0.75" to prevent interference with the blower
housing.
NOTE: Extreme caution must be taken when installing the trans-
former to the partition plate and wiring the transformers so as to
not damage the furnace control board wiring or other electrical
components.
