INSTALLATION INSTRUCTIONS
Plumbing
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 drain and dispose of per
local code.
• 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.
• Do not connect the drain pipe with an air-
conditioning evaporator coil drain.
