TANKLESS WATER HEATER 199
1.5 CONDENSATE REMOVAL
The specified vent configuration promotes the safe drainage of moisture from the
unit and exhaust venting without flowing 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 filled 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 bottom of the condensate trap at
the base of the unit.
1.5.2 Installing the Condensate Trap
1.
Fill the condensate trap cup with water.
2.
Install the condensate trap cup on 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 cup.

WARNING
Fill the trap with water before
initial startup of the unit to
prevent exhaust fumes from
entering the room. Never
operate the water heater
unless the trap is filled 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.
