UGTC Series Manual 15
Condensate
Condensate formation can occur in high efficiency
direct vent appliances. Without proper drainage
condensate will damage the heat exchanger.
To prevent condensate damage follow these
instructions.
DO NOT

Do not connect the condensate drain pipe directly
to the rain sewer.

Do not connect the condensate drain line with an
air conditioning evaporator coil drain.
MUST DO

Use only vent that is approved and identified as
acceptable for your particular model.

Slope the venting toward the appliance according
to the vent manufacturers installation instructions.

All condensate must drain and be disposed of
according to local codes.

Use only corrosion resistant materials for the
condensate drain lines such as PVC pipe or plastic
hose.

The condensate drain pipe (along its entire length)
must be at least the same diameter as the drain
line, (1/2 inch NPT).

The end of the condensate drain pipe should be
open to the atmosphere. The end should not be
under water or other substances.
Checklist for Venting and
Condensate
□
Verify proper clearances around the vents and air
intakes.
□
Ensure you have used the correct venting
products for the model installed and that you
have completely followed the venting
manufacturer’s installation instructions and these
installation instructions.
□
Verify that the vent system does not exceed the
maximum length for the number of elbows used.
INFORMATION

Water heaters have an integrated condensate
collector.

Regions of cold climate will create more
condensate in the vent system. The condensate
collector should be used in cold climates.

The condensate drain pipe should be as short as
possible and have a downward pitch.

If the condensate drain gets blocked, an diagnostic
code will display on the controller. If this occurs,
the condensate drain must be cleaned.

The condensate trap will automatically prime (self-
prime) during operation of the unit as condensate
forms. Condensate draining from the unit
indicates that the trap is full and that there is no
blockage in the condensate drain. It is not
necessary to add water to the condensate trap.

A condensate neutralizer kit, P/N 50000100-A , is
available from Giant. The kit allows condensate to
flow through neutralizing media that raises the pH
of the condensate to a level that will help prevent
corrosion of the drain and public sewer system.
