SL 35-199, SL 45-260 MODULATING GAS BOILERS
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 15.
1.5.2 Condensate Trap Assembly - Installation
1.
Undo Drain Spout Compression Nut (E), remove Drain Hose (G) from Trap
Drain Outlet (F). Place Vacuum breaker cap (J) over the Vacuum breaker
opening and push firmly home. Remove Upper Compression Nut and
Washer (C) and slide over Boiler Drain Outlet (A). Insert one Trap Hook barb
into the back mounting hole.
2.
Fill Trap with water,
and slide Trap Body (D) over Boiler Drain Outlet (A).
Swing Trap Hook (B) around the Drain Outlet (F) connection threads. Insert
remaining Trap Hook barb into the front hole. Pull the trap slightly downward
to seat it against the hook and tighten Upper Compression nut (C).
3.
Attach Drain Hose (G) and tighten Drain Spout Compression Nut (E).

WARNING
The Trap Hook 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.
