3.8 Closet installations
For installations in a confined space (such as a closet), ventilation openings may be needed through a
door or wall to prevent excessive heat from building up inside the space.
The appliance must not be exposed to surrounding air above 122°F (50°C) or below 32°F (0°C).
3.9 Installing a condensate trap
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).
Warning
Fill the trap with water before initially firing the boiler to prevent exhaust fumes from entering
the room. Never operate the boiler unless the trap is filled with water. Failure to comply will
result in severe personal injury or death.
Ensure the supplied trap is correctly
installed and filled with water.
When required, add (and maintain in
good condition) a neutralization tank.
For information on installing a
condensate neutralizer, see Installing
a condensate neutralizer on page 39.
The condensate trap must be installed
on the drain connection at the base of
the boiler. The condensate drain must
be piped to within 1" of a drain or
connected to a condensate pump. The
drainage line must slope down to the
drain at a pitch of ¼" per foot so
condensate runs towards the drain.
