For applications above 5,000 ft, a pressure switch change is required to provide safe and reliable operation. Table 2 and Table 3 indicate the correct pressure switch accessory for each unit model applied.

WARNING

Do not adjust the original pressure switch to allow operation at high altitude. An unsafe operation will result

Table 2: High altitude pressure switch usage 80% furnaces – upflow/horizontal and downflow/horizontal models

Table 3: High altitude pressure switch usage 95% furnaces –  upflow/horizontal and downflow/horizontal models

The high-altitude pressure switch must be changed by following this procedure:

1. Remove the burner access door. Replace the pressure switch in accordance with Figure 1 or Figure 2, and the following procedures.
