Condensate disposal

Condensate drain
1. The FTXL is a high effi ciency appliance that produces
condensate.
2. The 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
(KIT3087 for Models 400 - 500 and KIT3046 for Models
600 - 850). KIT3046 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.

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.
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.
The pump should have an overfl ow switch to prevent
property damage from condensate spillage. The switch
should be wired in series with the blocked drain switch
inside the boiler (see FIG. 10-1 on page 58).
