Condensate disposal

Condensate drain
1. Th e FTXL is a high effi ciency appliance that produces
condensate.
2. Th e condensate trap is sized for a 1" PVC outlet
connection pipe.
3. Plug the wiring connection from the condensate trap into
the connector located on the back of the unit.
4. Slope condensate tubing down and away from the boiler
into a drain or condensate neutralizing fi lter. Condensate
from the FTXL will be slightly acidic (typically with a pH
from 3 to 5). Install a neutralizing fi lter if required by
local codes.
A Neutralizer Kit (FIG. 9-1) is available from the factory
(100157721 for Models 400 - 500 and 100157700 for
Models 600 - 850).100157700 must be placed on a surface
that is a minimum of 3 inches lower than the condensate
trap with fi eld supplied piping (vacuum break) installed
between the condensate trap and the neutralizer kit.
5. Do not expose condensate line to freezing temperatures.

6. 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.
Th e pump should have an overfl ow switch to prevent
property damage from condensate spillage. Th e switch
should be wired in series with the blocked drain switch
inside the boiler (see FIG. 10-1 on page 59).

Installation & Operation Manual
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. Do
not use copper or black iron pipe, or fi ttings.
To allow for proper drainage on large
horizontal runs, a second line vent may
be required and tubing size may need to
increase to 1 inch (25 mm).
The condensate line
unobstructed, allowing
condensate. If condensate is allowed to freeze
in the line or if the line is obstructed in any
other manner, condensate can exit from
the boiler tee, resulting in potential water
damage to property.
