Installation & Operation Manual

9Condensate disposal

Condensate drain

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

2.The bottom of the boiler has a 1/2 inch pipe for connection of a 1/2 inch 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 wall mount boiler will be slightly acidic (typically with a pH from 3 to 5). Install a neutralizing filter if required by local codes.

A Neutralizer Kit is available from the factory (Kit 3087).

4.Do not expose condensate line to freezing temperatures.

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

6.Leave the top of the tee assembly installed in the unit open, this is needed as a vacuum break. The blocked drain switch will shut the boiler down before any condensate can flow out of the tee.

 

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.

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.

7.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. 10-1 on page 56).
