8)Condensate Drain Line - In systems where a concentric vent is used, all condensate which forms in the boiler or vent system collects in both the condensate vent adapter and the sump under the heat exchanger and leaves the boiler through the condensate trap. This trap allows condensate to drain from the boiler and vent while retaining flue gases. A length of corrugated drain hose is supplied with the boiler and is connected to the trap as shown in Figure 1.15. This hose may be routed through the back of the boiler or to the left side through the knockout provided. Route this hose to a drain or other suitable point for disposal. Note the following when disposing of the condensate:

a)If the condensate drain line must be extended, construct the extension from PVC or CPVC pipe. Insert the hose provided with the boiler into the end of the extension as shown in Figure 1.15.

b)Condensate is slightly acidic. Do not use metallic pipe or fittings in the condensate drain line. Do not route the drain line through areas that could be damaged by leaking condensate.

c)Some jurisdictions may require that the condensate be neutralized before being disposed of. Dispose of condensate in accordance with local codes.

d)Do not route, or terminate, the condensate drain line in areas subjected to freezing temperatures.

e)If the point of condensate disposal is above the trap, it will be necessary to use a condensate pump to move the condensate to the drain. In such cases, select a condensate pump that is approved for use with condensing furnaces. If overflow from this pump would result in property damage, select a pump with an overflow switch and use this switch to shut down the boiler. Alternatively, if heat is a necessity, use the overflow switch to trigger an alarm.

f)Do not attempt to move the trap from the location shown in Figure 1.15. Do not attempt to substitute another trap for the one provided with the boiler.

g)The vent shown in Figure 1.15 must be left open for the trap to work properly.
