DANGER
Hydrogen gas is produced in a hot water
system served by this heater that has not
been used for a long period of time (2 weeks
or more). Hydrogen gas is extremely
flammable. To reduce the risk of injury under
these conditions, it is recommended that the
hot water faucet be opened for several
minutes at the kitchen sink before using any
electrical appliance connected to the hot
water system. When hydrogen is present,
there will probably be an unusual sound
such as air escaping through the pipe as the
water begins to flow. There should be no
smoking or open flame near the faucet at
the time it is open.
CAUTION
Any water heater should be installed in such
a manner that if it should leak, the resulting
flow of water will not cause damage to the
area in which it is installed. National
Plumbing codes require a drain pan for any
water heater installation. Failure to install
one is the sole responsibility of owner
and/or installer. Reference UPC 2006
(Uniform Plumbing Code) Section 508.1, or
IPC 2006 (International Plumbing Code)
Section 504.7.
CAUTION
Prior to connecting the power supply, ensure
tank is full of water and system is purged of
air.
NOTICE
Tank failure due to neglecting to maintain
the anode rod is not covered under
warranty (see Section 5 Maintenance).
