• Installed indoors close to
the center of the plumbing
system.

adequate oor drain or external to
the building (See page 12, gure 6).
• In an area that will not freeze.
• In an area that is suitable for
installing the water heater vercally.

The locaon has adequate
space (clearances) for periodic

6
Avoid locaons such as acs,
upper oors, or where a leak
might damage the structure
or furnishings. Due to the normal
corrosive acon of water, the tank will
eventually leak. To minimize property
damage from leaks, inspect and
maintain your water heater in
accordance with this manual’s
instrucons. Install a suitable drain pan
under the water heater piped to an
adequate drain. Inspect the drain pan,
pipes, and surrounding area regularly
and x any leaks found. Drain pans are
available at local plumbing supplier.
Leaks are frequently in the plumbing
system itself and not the water heater.
