FIGURE 35
Condensate line must slope downward away from the trap
to drain. If drain level is above condensate trap, conden-
sate pump must be used. Condensate drain line should
be routed within the conditioned space to avoid freezing of
condensate and blockage of drain line. If this is not possi-
ble, a heat cable kit may be used on the condensate trap
and line. Heating cable kit is available from Lennox in var-
ious lengths; 6 ft. (1.8m) - kit no. 26K68; 24 ft. (7.3m) - kit
no. 26K69; and 50 ft. (15.2m) - kit no. 26K70.
