to evacuate the condensate through an open gutter to prevent the risk of ice forming and avoid
exposure of the corrosive condensate to the external environment.
The condensate must be neutralized before being evacuated to the sewer, which can be achieved by
mixing the condensate with lime or with drain water coming from washing machines, dish washing
machines, etc., which normally has a base pH.
The connection to the sewer will be through a closed, but visible drain. Given the high acidity (pH 3 to
5) of the condensate, only plastic material may be used for the condensate evacuation pipes.
Moreover, it must be dimensioned and constructed so as to allow the correct out-flow to the drain,
preventing any bottleneck and any leakage.
Consult local codes regarding condensate neutralization. Neutralization may be obtained by mixing it
with the buildings drain water or with limestone, which normally has a base pH. AERCO offers a
condensate neutralizing kit and a neutralizing tank, for preparing condensate waste for safe
evacuation into a sewer system, if other means of neutralizing the waste are not available.
Figure 4-8: MODULEX EXT Condensate Piping
The outlet of the condensate drain pipe exits from the right side of the boiler, just below the RIGHT-
SIDE flue outlet opening.

If i
t is not possible to use a 4’’ (101mm) base or housekeeping pad on which to place the boiler, install
the boiler on the floor and provide a well or trough (minimum of 4’’ - 101 mm deep) in which to lodge
the U of the condensate piping. See Figure 4-8.

•
Before commissioning the boiler, fill the condensate siphon with water, at the dedicated
filling-up plug. See Figure 4-8.
•
Do not install the condensate drain where freezing may occur.
Use materials approved by the authority having jurisdiction in your area. In the absence of such
authority, PVC and CPVC pipe must comply with
ASTM D1785
,
F441
or
D2665
. Cement and primer
must comply with
ASTM D2564
or
F493
.
For Canada, use ULC certified PVC or CPVC pipe, fittings and cement.
Periodic cleaning of the condensate disposal system must be carried out.
