8 Condensate disposal
Condensate drain
1.The Crest is a high efficiency appliance that produces condensate.
2.The rear of the boiler has a 1 inch (25.4 mm) stainless steel drain fitting and a 3/8 inch (9.8 mm) stainless steel vent line for connection to the condensate trap.
3.Connect the 1 inch (25.4 mm) fitting to the 1 inch (25.4
mm)fitting on the condensate trap with the factory supplied silicone hose. Secure the hose to the condensate trap and the boiler using the factory supplied hose clamps.
4.Connect the 3/8 inch (9.8 mm) fitting to the 3/8 inch (9.8
mm)fitting on the condensate trap (shipped loose) with the factory supplied silicone hose. Secure the hose to the condensate trap and the boiler using the factory supplied hose clamps.
5.The condensate trap must be installed at the same level or below the boiler base.
6.The condensate trap is sized for a 1" PVC outlet connection pipe.
7.Plug the wiring connection from the condensate trap into the connector located on the back of the unit.
8.Slope condensate tubing down and away from the boiler into a drain or condensate neutralizing filter. Condensate from the Crest will be slightly acidic (typically with a pH from 3 to 5). Install a neutralizing filter if required by local codes.

9. 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. | |
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 (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. |
10.A condensate removal pump is required if 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. The switch should be wired to the auxiliary device proving switch terminals on the low voltage connection board.
