Condensate line must be sloped downward away from
condensate trap to drain. If drain level is above con-
densate trap, condensate pump must be used. Con-
densate drain line should be routed within the condi-
tioned space to avoid freezing of condensate and
blockage of drain line. If this is not possible, a heat
cable kit may be used on the condensate trap and line.
Heating cable kit is available from Lennox in various
lengths; 6 ft. (1.8m) − kit no. 18K48; 24 ft. (7.3m) − kit
no. 18K49; and 50 ft. (15.2m) − kit no. 18K50.
CAUTION
Do not use copper tubing or existing copper
condensate lines for drain line.
5 − If unit will be started immediately upon completion of
installation, prime trap per procedure outlined in Unit
Start−Up section.
6 − Glue the provided cap onto the unused condensate
drain line stub.
