Connection To Vent Pipe; Condensate - Kenmore Elite 153.331010 Use & Care Manual

CONNECTION TO VENT PIPE

The vent system connects to the vent pipe with an elbow
or rubber coupling. This coupling includes gear clamps.
These connections must be properly seated and tightened
to prevent the leakage of fl ue gases into the installation
area.
With 2 in. venting the straight rubber adapter is used for the
connection to the vent pipe. With 3 in. venting a transition
adapter is required to change from the 2 in. vent pipe to
the 3 in. vent size.
Clean and lightly sand the end of the vent piping that will
connect to the rubber coupling.
Loosen the upper clamp on the rubber adapter and insert
the sanded end of the vent pipe and tighten the gear
clamp.
NOTE: Do not glue or seal in the rubber coupling. Check
the venting system to ensure that there is no stress on the
connection or the vent pipe which will create a twisting or
bending.

CONDENSATE

This water heater is a condensing unit and requires a drain
to be located in close proximity to allow the condensate
to drain safely. The condensate drains from the unit at
the exhaust tee located at the bottom of the unit (see
Figure 30). Condensate from this water heater is mildly
acidic. Please note that some local codes require that
condensate is treated by using a pH neutralizing fi lter
prior to disposal.
Caution must be used to ensure that the drain is free and
clear of debris and will not allow backfl ow through the
condensate tube. Consideration must be given to avoid
freezing of the condensate lines which could result in
excessive build up of condensate inside the water heater.
Waterproof heat tape may be required to prevent freezing
of the condensate lines. Please ensure that the outlet of
the condensate drain does not create a slippery condition
which could lead to personal injury.
To operate properly and prevent exhaust gases from
escaping through the condensate trap, the trap must

3")
contain some water. Before being started for the fi rst time,
water must be added to the trap. Remove the condensate
tube (if installed) and add water to the trap through the
hole for the condensate tube until it fl ows from the hole.
(Re)install the condensate tube.

CONDENSATION WARNING:
THIS WATER HEATER IS A CONDENSING UNIT AND
REQUIRES A DRAIN TO BE LOCATED IN CLOSE
PROXIMITY TO ALLOW CONDENSATE TO DRAIN
SAFELY. THE CONDENSATE DRAINS FROM UNIT AT
THE EXHAUST ELBOW LOCATED AT BOTTOM OF
UNIT.
NOTE: IT IS IMPORTANT THAT THE CONDENSATE
TUBE NOT BE ELEVATED ABOVE THE CONDENSATE
TRAP OUTLET (SEE FIGURE 30). CONDENSATE
BUILD-UP WILL BLOCK THE EXHAUST OUTLET,
WHICH WILL CAUSE IMPROPER OPERATION. WITH
SOME INSTALLATIONS IT IS RECOMMENDED TO
INSTALL A CONDENSATE PUMP.
NOTE: Barbed fi tting not required if hard piping is used
to drain condensate.
