2Maintenance schedule (continued)

3.Fill with fresh water until the water begins to pour out of the drain.

4.Replace the cap. Press the cap onto the trap until the cap makes contact with the drain.

5.Replace the retaining screw.

The condensate trap (FIG. 2-1) must be ￿ WARNING filled with water during all times of

boiler operation to avoid flue gas emission from the condensate drain line. Failure to fill the trap could result in severe personal injury or death.

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

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

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. Call your qualified service technician to inspect the boiler and system.

A Neutralizer Kit is available from the factory (Kit 3087 for Models 399 - 500 and Kit 30002 for Models 600 - 800). Call your qualified service technician to install.

4.Install the 1/2 inch PVC tee assembly (shipped with the unit) as shown in FIG. 2-2. Call your qualified service technician to inspect the boiler and system.

5.Leave the top of the 1/2 inch 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. 2-2).

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. Call your qualified service technician to inspect the boiler and system.

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. Call

your qualified service technician to inspect the boiler and system.
