.
The
water
heater
comes factory-equipped with
a
fused circuit
board,
which will protect the circuit board from wiring shorls. lf
the fuse
should activate, the
v,,aier
heater
will not operate.
Before replacing
the fuse, check for a shod
external
to the board.
Once
the shod
is
corrected,
replace
the 2 amp
fuse
with a
mini ATO
style fuse.
Do
nol
install a
fuse
larger
than 3
amps.
o
lf
the fuse
is
good
and
the unit
is
inoperative, check for
excessively
high
voltage to the unit
(more
than
14 volts).
.
lf
the
previous
two
steps did not
solve
the problem, check
the
thermal cut-off
(Ftc
3-l). The
thermal
cutoff
is
a device installed
in
the
power supply
line.
This device
will
shut off electrical power and stop
heater operation when activated.
For
example, if an obstruction
within the flue tube should occur,
as
described
in
the Preventative
Maintenance section, the burner flame/heat may contact the cutoff,
resulting
in
a melting of the fuse element incorporated
in the
thermal
cutoff.
In
order
to
restore power and proper operation of the
water
heater,
the obstruction must be removed and the thermal
cutoff
must be
replaced.
