CONDENSATE DRAIN INSTALLATION
Installation must conform with these instructions and local building
codes.
Field supplied materials required for installation include:
•
Approved PVC cement and PVC primer.
•
1/2 inch PVC pipe - minimum length to equal the distance
between the water heater and a suitable building drain.
•
1/2 inch PVC fittings (elbows, couplings, and adapters)
necessary to install a condensate drain line between the Exhaust/
Condensate Elbow Assembly and a suitable building drain.
•
Floor mounted standoffs to brace the drain line.
INSTALLATION NOTES
1. The condensate drains from the water heater's covered by
this instruction have PH levels between 4.3 and 5.0. Install a
commercially available neutralizing kit if required by local codes.
Lower PH levels are acidic. Do not connect a metal condensate
drain line, such as copper pipe, to the water heater for this reason.
2. The field installed condensate drain line must not be less than
1/2 inch PVC in size.
3. The exhaust elbow has a built in condensate trap. Do not install an
additional trap in the condensate drain piping. DO NOT remove,
modify or alter the factory condensate trap.

INSTALLATION INSTRUCTIONS
1. Ensure the water heater's Enable/Disable switch is in the
"Disable" position.
2. Install a 1/2 inch PVC condensate drain line between condensate
drain connection on the Exhaust/Condensate Elbow and a suitable
building drain. The condensate line must slope to an open drain,
see Figure 37.
3. Terminate the condensate drain piping with an elbow above the
drain. Ensure that any discharge will exit the condensate drain
line no more than 6 inches (15.2 cm) above a suitable building
drain, or external to the building, see Figure 37.
• NOTE: In cold climates it is recommended the conden-
sate drain be terminated at a suitable drain inside the
building.
4. Ensure the condensate drain line is not elevated above the
condensate drain connection on the Exhaust/Condensate Elbow,
see Figure 37.
5. Brace the condensate drain line with floor-mounted standoffs
every three feet.
6. Ensure that the condensate drains freely during start up, see
Start Up on page 50.
7. Condensate clean out cap must be on and tight when unit is in
operation.
