1.5 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.
2. Ensure the supplied trap is correctly installed and filled with water.
3. 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 24.
1.5.2 Condensate Trap Assembly - Installation
1. Undo the Drain Spout Compression Nut (E), remove Drain Hose (G) from the Trap
Drain Outlet (F). Place the Vacuum breaker cap (J) over the Vacuum breaker opening
and push firmly home. Remove the Upper Compression Nut and Washer (C) and
slide over the Boiler Drain Outlet (A). Insert one Trap Hook barb into the back of
mounting hole.
2. Fill Trap with water, and slide Trap Body (D) over Boiler Drain Outlet (A) - (see
Figure 24).
3. Attach Drain Hose (G) and tighten Drain Spout Compression Nut (E).

WARNING
The trap retainer must be
installed as instructed and all
trap fittings must be tightened as
instructed to prevent leakage of
flue gasses.
Failure to comply may result in
severe personal injury or death.
WARNING
Fill trap with water before boiler
is first fired to prevent exhaust
fumes from entering room. Never
operate the boiler unless the trap
is filled with water.
Failure to comply will result in
severe personal injury or death.
