1.5 CONDENSATE REMOVAL
IBC’s specied vent conguration promotes the safe drainage of moisture from the boiler
and exhaust venting without owing 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:
• 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 lled with water.
• When required, add (and maintain in good condition) a neutralization tank.
1.5.1 Condensate Trap
The condensate trap must be installed on the drain connection at the base of the boiler as
shown in Figure 22.
