4.14 Condensate Disposal
WARNING!
The condensate trap (Fig. 4-8, item "B") MUST be filled with water or combustion gases will
enter the room. The condensate neutralizer tank must be installed into the unit exactly as
shown in Figure 4-8. Do NOT remove the condensate neutralizer tank from its position while
the unit is in operation, as this will result in dangerous carbon monoxide escaping and
creating a very dangerous situation.
The unit is equipped with a condensate neutralizer tank for the evacuation of condensate and to
prevent the leakage of combustion products. The condensate drains from the flue exhaust outlet
"A" through pipe to condensate neutralizer tank, drains through pipe "C" (Figure 4-8) and "E"
(Figure 4-9, and empties into the floor drain or drain pan, "F" (Fig. 4-9).
NOTE:
In newer units, hose "A" (Fig. 4-8) attaches to a port at the bottom of flue, rather than the
side.
The condensation disposal system must:
•
slope the condensate tubing down and away from the boiler into a drain or drain pan
(See Figure 4-9). Condensate from the boiler will be slightly acidic (around pH 4). The
neutralizing tank (see Figure 4-8, item "B") is built into the boiler and will neutralize the
condensate products;
•
be carried out with a pipe with an internal diameter equal to or greater than 3/4 inches
(19 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;
