CONDENSATE DRAIN CONNECTION

FROZEN AND BURST WATER PIPE HAZARD
Failure to protect against the risk of freezing may result in property
A11574
damage.
Special precautions MUST be made if installing furnace in an area
which may drop below freezing. This can cause improper operation or
damage to equipment. If furnace environment has the potential of
freezing, the drain trap and drain line must be protected. The use of
accessory drain trap heaters, electric heat tape and/or RV antifreeze is
required for these installations.
PROPERTY DAMAGE HAZARD
Failure to follow this caution may result in burst water pipes and/or
property damage.
If a condensate pump is installed, a plugged condensate drain or a failed
pump may cause the furnace to shut down. Do not leave the home
unattended during freezing weather without turning off water supply
and draining water pipes or otherwise protecting against the risk of
frozen pipes.
DO NOT trap the drain line in any other location than at the condensate
drain trap supplied with the furnace. If possible, DO NOT route the drain
line where it may freeze. The drain line must terminate at an inside drain
to prevent freezing of the condensate and possible property damage.
Special precautions MUST be made if installing furnace in an area
A170135
which may drop below 32°F (0°C). This can cause improper operation or
damage to the equipment. If the furnace environment has the potential of
freezing, the drain trap and drain line must be protected. In areas where
the temperature may be below 32°F (0°C), a Condensate Freeze
Protection kit is strongly recommended. The kit includes a condensate
