Connect condensate drain

1.Remove condensate trap line from bag. Prepare and install per page 19. Secure to jacket by attaching PVC tee as shown in Figure 13.
2.Slide trap line onto flue outlet condensate connection and PVC reducing elbow as shown in Figure 12, 13 or 14. Secure with hose clamps.
3.Connect condensate drain tubing to the ½" PVC tee and run to floor drain or condensate pump. Use ½" PVC or CPVC pipe; or 5/8" I.D. tubing.
Use materials approved by the authority having jurisdiction. In the absence of other authority, PVC and CPVC pipe must comply with ASTM D1785, F441 or D2665. Cement and primer must comply with ASTM D2564 or F493. For Canada, use CSA or ULC certified PVC or CPVC pipe, fittings and cement.
4. Leave the top of the ½" tee OPEN. This is needed as a vacuum break.

5.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.
6.Condensate from the Ultra boiler will be slightly acidic (typically with a pH from 3.2 to 4.5). Install a neutralizing filter if required by local codes.
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 manor, condensate can exit from the boiler tee, resulting in potential water damage to property.
