9Condensate 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. 9-1).

3.Slope condensate tubing down and away from the boiler into a drain or condensate neutralizing filter. Condensate from the 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. 9-1) is available from the factory (KIT3087 for Models 399 - 500 and KIT3046 for Models 600 - 800).

4.Install the 1/2 inch (12.7 mm) PVC tee assembly (shipped with the unit) as shown in FIG. 9-1.

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.

7.Use only plastic tubing or piping as a condensate drain line (FIG. 9-1).

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. For Canada use CSA or ULC certified

 

PVC or CPVC pipe, fittings, and cement.

 

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 unobstructed, 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 boiler is below 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 to the auxiliary device proving switch terminals on the low voltage connection board.
