7.5 - Condensate
disposal
WARNING!!!
The
condensate trap must be
connected to the boiler per
the following instructions or
combustion gases will enter
the room. This can result in
excessive levels of carbon
monoxide which can cause
severe personal injury or
death!
This boiler produces water as a
byproduct of combustion. The boiler
is equipped with a condensate
trap, Figure 3-1, item “46”, for the
evacuation of condensate and to
prevent the leakage of combustion
products. The condensate trap drains
through pipe shown in Figure 7-2
item “C”. The condensation disposal
system must:

be connected by means of an
appropriate trap capable of
preventing the pressurization of the
condensate system and the return
of sewer gas (see fi gure 7-8);

slope condensate tubing down and
away from the boiler into a drain
or condensate neutralizing fi lter.
Condensate from the boiler will be
slightly acidic (around pH 4). Install
a neutralizing fi lter if required by
local codes.
CAUTION!!!
Use materials
approved by the authority
having jurisdiction. In the
absence of other authority,
PVC and CPVC pipe must
comply with ASTM D1785 or
D2845. Cement and primer
must comply with ASME D2564
or F493. For Canada use CSA
or ULC certifi ed PVC or CPVC
pipe, fi ttings, and cement.

comply with national and/or local
codes for condensate neutralizer
between pipe “C” of fi gure 7-2 and
the waste disposal system;

be carried out with a pipe with
an internal diameter equal to or
greater than 1/2 in (13 mm);

be installed in such a way so as to
avoid the freezing of the liquid;

never discharge into gutters or rain
collectors;

be properly pitched towards the
point of discharge avoiding high
points, which could place the
condensate system under pressure.
CAUTION!!!
The condensate
drainage system is designed
to empty all the condensate
produced by one boiler
only. Each boiler must
be equipped with its own
condensate drainage system
or the drainage system may
malfunction.
A condensate removal pump is
required if the boiler is below the
drain. When installing a condensate
pump, select one approved for use
with condensing boilers and furnaces.
The pump should have an overfl ow
switch to prevent property damage
from condensate spillage.
COMMONWEALTH OF
MASSACHUSETTS SPECIAL
REQUIREMENT
When the boiler is installed and
used in the Commonwealth of
Massachusetts, a neutralization
unit MUST be installed in the
condensate removal system.

CAUTION!!!
Minimum
air gap of ½ between
discharge pipe and
drain. Failure to do
this will damage the
unit and void the
warranty!
