SFT 199 TANKLESS WATER HEATER
1.5 CONDENSATE REMOVAL
IBC’s speci ed vent con guration promotes the safe drainage of moisture
from the unit and exhaust venting without owing liquids back through the heat
exchanger.
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 minimum 1/4” per foot slope back to the vent connection, with
appropriate hangers to maintain that gradient (check with the venting
manufacturer as their slope requirement may be stricter).
2. Ensure the supplied trap is correctly installed and lled with water.
3. When required, add (and maintain in good condition) a pH neutralization
tank.
1.5.1 Condensate Trap
The condensate trap must be installed on the drain connection at the base of the
unit.
1.5.2 Installing the Condensate Trap
1. Fill the condensate trap cup with water.
2. Place the condensate trap cup into the condensate trap base and twist toward
the right.
3. Attach the drain hose to the condensate trap outlet located to the left of the
condensate trap.

WARNING
Fill the trap with water before
rst ring the unit to prevent
exhaust fumes from entering
the room. Never operate the
water heater unless the trap is
lled with water.
Failure to comply will result
in severe personal injury or
death.
NOTE
It is the responsibility of
the installing and/or service
Contractor to advise and
instruct the end user on how
to perform the Trap cleaning
procedure, and to advise
that the trap be checked at
least every two months and
cleaned as required.
