9Condensate disposal

Condensate drain

1.This water heater is a high efficiency appliance that produces condensate.

2.Slope condensate tubing down and away from the water heater into a drain or condensate neutralizing filter. Condensate from the Shield water heater 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 (KIT3087).

3.Leave the top of the 1/2 inch tee OPEN (FIG. 9-1). This is needed as a vacuum break.

NOTICE

To allow for proper drainage on large 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 water heater tee, resulting in potential water damage to property.

4. 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.

5.A condensate removal pump is required if the water heater is below the drain. When installing a condensate pump, select one approved for use with condensing water heaters 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.
