CONDENSATE REMOVAL

IBC's specified vent configuration promotes the safe drainage of moisture from
the boiler and exhaust venting without flowing liquids back through the heat
exchanger (as done by some other condensing boilers).
Reliable system operation requires (1) proper design and installation of exhaust
venting to allow condensate to run back to the drain/trap; (2) acid neutralization
as appropriate. To achieve these:
1. Allow for a 1/4" per foot slope back to the vent connection, with appropriate
hangers to maintain that gradient.
Ensure the supplied trap is correctly installed and filled with water.
2.
When required, add (and maintain in good condition) a neutralization tank.

1.5.1 Condensate Trap
A condensate trap must be installed on the drain connection at the base of the
boiler as shown in Figure 15.
