3.13 Condensate Disposal
WARNING!
The condensate trap, as shown in Figure 3-18, item “B”, MUST be
filled with water or combustion gases will enter the room. The
condensate neutralizer box must be installed into the unit, exactly
as shown in Figures 2-3 and 2-4 (399/500) or Figures 2-6 and 2-7
(750/1000). Do NOT remove the condensate neutralizer box from
its position while the unit is in operation, as this will result in
combustion gases entering the room, which can result in
excessive levels of carbon monoxide.
The unit is equipped with a condensate neutralizer box, Figure 3-18, item “B”, for the evacuation
of condensate and to prevent the leakage of combustion products. The condensate drains
through pipe shown in Figure 3-18 item “C” and Figure 3-19 item “A”. The condensation
disposal system must:
• slope the condensate tubing down and away from the boiler into a drain or drain pan
(See Figure 3-17). Condensate from the boiler will be slightly acidic (around pH 4). The
neutralizing box (see Figure 3-18, 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;
