Installation & Operation Manual

8 Condensate disposal

Condensate drain

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

2.The rear 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. 8-1).

3.Slope condensate tubing down and away from the boiler into a drain or condensate neutralizing filter. Condensate from the SYNC 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. 8-1) is available from the factory (KIT3046).

4.Install the 1/2 inch (12.7 mm) PVC tee assembly (shipped with the unit) as shown in FIG. 8-1.

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.

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.

7.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.
