INSTALLATION INSTRUCTIONS
WARNINGS:
• When pipe insulation is not rated for the appropriate
weather conditions, install electric heat tracing or
equivalent to prevent freezing of the pipes.
• DO NOT insulate or block drain valve on the hot outlet
fitting.
• If pipes are allowed to freeze, the water heater and the
pipes may malfunction or leak due to freezing water.
NOTICE:
The hot and cold water supply pipes should be insulated to
provide additional freeze protection.
For increased energy efficiency, use pipe insulation as
shown in the diagram. Insulate the pipes all the way
to the top. DO NOT cover any drain or pressure-relief
valve(s).

Condensate Drainage
Be sure the condensate runs freely to a drain and does
not accumulate inside the water heater. In cold climates,
precautions may need to be taken to ensure that the
condensate drain does not freeze.
All condensation must be drained and disposed of per
local codes and requirements.
If the condensate drain gets blocked, an error code
will display on the remote control. If this occurs, the
condensate drain must be cleared.
Use only PVC or CPVC pipe or flexible tube for the
condensate drain line.
The drain pipe (along its entire length) must be at least
the same diameter as the drain line.
The drain line should be as short as possible and have a
downward slope toward the end.
The end of the drain pipe should be open to the
atmosphere. The end should not be under water or other
substances.
DO NOT connect the drain pipe directly to the drain
sewer.
