Condensate Drain Protection
Freezing condensate left in condensate trap and drain line may
cause cracks, and possible water damage may occur. Freeze
protection of the condensate trap is required when the furnace is
installed in the horizontal position and the attic temperature is
below 32 deg. F (0 deg. C).
If freeze protection for the condensate trap is required, use
condensate freeze protection accessory.
See Product Data for current kit offering.
The remaining condensate drain line can be protected by using a 3
to 6 watt per ft. (.3M) at 120v and 40_F(4.4_C) self--regulating,
shielded, and waterproof heat tape. Wrap field drain pipe with heat
tape, approximately 1 wrap per ft. (.3M). Follow manufacturer’s
recommendations and installation instructions supplied with heat
tape.
