Condensate
The TGHE series water heaters are factory equipped with a condensate trap and drain line. All condensate must drain and be disposed of per local codes. Use only vent that is approved venting; do not use PVC, CPVC, ABS, or galvanized material to vent this appliance.
If the condensate drain gets blocked, an error code will display on the controller. If this occurs, the condensate drain must be cleaned. The condensate trap will automatically 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.
Use only PVC or CPVC pipe for the condensate drain line. The drain pipe, along its entire length, must be at least the same diameter as the drain line (1/2” NPT). The drain pipe must be as short as possible and have a downward pitch. The end of the drain pipe must be open to the atmosphere. The end must not be underwater or other substances. Do not connect the drain pipe directly to the rain sewer. Do not connect the condensate drain line with an air conditioning evaporator coil drain.
To minimize freezing of the condensate, run the condensate drain line through an interior wall or between insulation and an interior wall.
CAUTION
Do not plug or cap the integrated condensate line. Without proper drainage or disposal, condensate will damage the water heater.
Recommended Vent/Air Intake Terminal Position
Terminals should be so positioned as to avoid products of combustion entering openings into buildings or other flues or vents.
