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.

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.

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. 2-2).
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. 2-2) is available from the factory
	(KIT3046).

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. Call

your qualified service technician to inspect the boiler and system.

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