DRAINING THE CONDENSATE
In certain conditions, installations in unconditioned space or having long horizontal or vertical runs
may accumulate condensate.
Condensate is known to be acidic; refer to local, state (provincial) or federal codes for propper
handling methods.
In order to prevent condensate from draining back into the water heater, we recommend a
condensate trap and drain to be installed in a horizontal vent section as close as practical to the water
heater vent connection.
Not following proper condensate procedures will void warranty.
Eccotemp also recommends adding a backflow preventer to keep freezing outside air from reaching
the water heater. Consult with an installation professional for proper installation.

The system will not operate if there is excessive restriction (pressure drop)
in the venting system. A maximum of 32 feet of vent pipe may be used
provided there is only one 90° elbow in the system. If additional elbows are
required: two elbows can be used with 27 feet, and three elbows can be
used with 22 feet of vent pipe.
A 90° elbow is equivalent to 5 feet of straight pipe. A 45° elbow is
equivalent to 2 feet 6 inches of straight pipe .

The termination elbow does not count as an elbow when determining total
vent lengths.

The vent must be installed with a slight downward slope of 1/ 4" per foot of
horizontal run toward the vent terminal (see diagram below). This ensures
that any condensate formed during operation is evacuated from the water
22'
heater.
A 1/4" per foot upward slope is acceptable when it is not possible to vent
with a downward slope, however, a UL approved Category III Stainless Steel
condensate trap MUST be installed at the beginning of the horizontal run
(See page 19 "Typical Horizontal Termination w/ 1/4" per foot UPWARD
Slope" or page 24, "Standard Vertical Category III Stainless Steel" for
examples).
