J. Condensate Trap and Drain Line
All condensate which forms in the boiler or vent system passes through the heat exchanger and out of a bottom
drain port which is connected to the condensate trap with a hose. This trap allows condensate to drain from the heat
exchanger while retaining flue gases in the boiler. This trap is an integral part of the boiler but must be connected to
a drain pipe as shown in Figure 7.47
.
A length of corrugated tubing is supplied with the boiler and is connected to
the trap as shown in Figure 7.47. Note the following when disposing of the condensate:
1. If the corrugated condensate drain line must be extended, construct the extension from PVC or CP
VC pipe.
Insert the hose
provided with the boiler into the end of the extension as shown in Figure 7.47.
2. 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.
3. Some jurisdictions may require that the condensate be neutralized before being disposed of. Dispose of
condensate in accordance with local codes.
4. Do not route, or terminate, the condensate drain line in areas subjected to freezing temperatures.
5. 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
boilers. 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.
6. Do not attempt to move the trap from the location shown in
Figure 7.47.
Do not attempt to substitute another trap
for the one provided with the boiler.
7. The trap vent is connected to a barbed fitting attached to the right side panel with rubber tubing and must be left
open for the trap to work properly.
NOTICE
Boiler condensate is corrosive. Route condensate drain line in a manner such that any
condensate leakage will not cause property damage.
Some jurisdictions may require that condensate be neutralized prior to disposal.
Use materials approved by the authority having jurisdiction.
WARNING Asphyxiation Hazard. Failure to install the condensate drain in accordance with the above
instructions could cause flue gas to enter the building, resulting in personal injury or death.
