6 Condensate disposal

Condensate drain

1.This boiler is a high efficiency appliance that produces condensate.

2.The side of the boiler has a 1/2 inch (12.7 mm) PVC union for connection of a 1/2 inch (12.7 mm) PVC pipe (FIG. 6-1).

3.Slope condensate tubing down and away from the boiler into a drain or condensate neutralizing filter. Condensate from the Outdoor Knight XL will be slightly acidic (typically with a pH from 3 to 5). Install a neutralizing filter if required by local codes.

A Neutralizer Kit (FIG. 6-1) is available from the factory (KIT3087 for Models 400 - 501 and KIT3046 for Models 601 - 801).

4.Install the 1/2 inch (12.7 mm) PVC tee assembly (shipped with the unit) as shown in FIG. 6-1.

5.Leave the top of the 1/2 inch (12.7 mm) tee OPEN. This is needed as a vacuum break.

6.Do not expose condensate line to freezing temperatures. Precautions should be taken to protect the condensate management and disposal system during extended periods of outdoor temperatures below 32°F.

7.Use only plastic tubing or piping as a condensate drain line (FIG. 6-1).

NOTICE

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.

 

To allow for proper drainage on large

NOTICE

horizontal runs, a second line vent may

 

be required and tubing size may need to

 

increase to 1 inch (25 mm).

The condensate line must remain unbstructed, allowing free flow of 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.

8.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 overflow 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. 7-1 on page 34).
