Gas inlet
(1)
Before
connecting
the
gas
supply,
check
the
rating
plate
on
the
left
side
of
the
right
front
cover
to
be
sure
that
the
heater
is
rated
for
the
same
gas
to
which
it
will
be
connected.
(2)
All
such
pipe
shall
be
either
new
or
previously
used
for
no
other
purpose
than
conveying
gas;
and
must
be
in
good
condition
and
free
from
internal
obstructions.
Burred
ends
shall
be
reamed
to
the
full
bore
of
the
pipe.
All
fittings
used
shall
be
of
malleable
iron,
yellow
brass,
or
approved
plastic
fittings.
(3)
When
your
connections
are
made,
check
for
gas
leaks
at
all
joints
(this
includes
all
existing
piping).
Apply
soapy
water
to
all
gas
fittings
and
gas
valve.
Soap bubbles are a sign of a leak.
NOTE:
No substance other than air, carbon dioxide or nitrogen can be introduced into the gas
piping.
NOTE:
If you have a leak, shut off the gas. After verifying the leak, tighten appropriate fittings to
stop leak. Turn the gas on and check again with a soapy solution.
Never test for gas leaks using a
match or flame.

Cold water inlet
(1)
When
facing
the
heater,
the
cold
water
inlet
is
on
your
right
and
the
hot
water
outlet
is
on
your
left.
Although
water
piping
throughout
your
structure
may
be
other
than
copper,
we
recommend
that
copper
piping
be
used
for
at
least
0.92
m
before
and
after
the
heater
(follow
local
codes).
Keep
water
inlet
pipe
to
no
less
than
1/2”
diameter
to
allow
the
full
flow
capacity.
(2)
Remember
that
water
pressure
must
be
sufficient
to
activate
the
heater
when
drawing
hot
water
from
the
top
floor.
If
the
hot
and
cold
connections
to
the
heater
are
reversed,
the
heater
will
not
function.
1/2’’Copper
or
brass
fittings
work
best
when
connected
to
the
connectors.
The
flexible
type
connectors
will
make
instillation
easier
and
seals
to
the
water
valve
by
means
of
a
union
connection
with
a
washer
type
gasket
at
the
joint.
No
pipe
dope
or
thread
tape
is
to
be
used
at
this
joint.
Be
certain
there
are
no
loose
particles
or
dirt
in
the
piping.
(Fig.

(3)
Water
pressure
must
be
sufficient
to
activate
the
water
heater,
the
maximum
pressure
for
the
appliance
is
10bar,even
with
the
effects
of
water
dilation,
the
water
pressure
in
the
appliance
shall
not
exceed
this
value.
•
Hot water outlet
Use
a
flexible
or
rigid
pipe
to
connect
with
the
sprayer
without
valve.
If
a
valve
or
switch
is
connected
to
the
sprayer,
the
outlet
pipe
shall
not
use
heat
and
pressure
unendurable
material
such
as
plastics,
aluminum
pipes,
so
as
to
avoid
the
pipe
from
breaking
and
scalding
the
user.
