INSTALLATION
1.
Follow
all
local
codes,
or
in
the
absence
of
local
codes,
follow
the
most
recent
edition
of
the
National
Fuel
Gas
Code:
ANSI
Z223.1/NFPA
54
in
the
USA
or
CAN/CSA
B149.1
Natural
Gas,
Propane
Installation
Code
in
Canada.
2.
All
gas
water
heaters
require
careful
and
correct
installation
to
ensure
safe
and
efficient
operation.
This
manual
must
be
followed
exactly.
Read
the
“Safety
Guidelines”
section
in
the
installation
manual.
3.
The
manifold
gas
pressure
is
preset
at
the
factory.
It
is
computer
controlled
and
should
not
need
adjustment.
4.
Maintain
proper
space
for
servicing.
Install
the
unit
so
that
it
can
be
connected
or
removed
easily.
Refer
to
the
Clearances
Section
on
p.
8
in
the
installation
manual
for
proper
clearances.
5.
The
water
heater
must
be
installed
in
a
location
where
the
proper
amount
of
combustible
air
will
be
available
to
it
at
all
times
without
obstructions.
6.
The
electrical
connection
requires
a
means
of
disconnection,
to
terminate
power
to
the
water
heater
for
servicing
and
safety
purposes.
7.
Do
not
install
the
unit
where
the
exhaust
vent
is
pointing
into
any
opening
in
a
building
or
where
the
noise
may
disturb
your
neighbors.
Make
sure
the
vent
termination
meets
the
required
distance
by
local
code
from
any
doorway
or
opening
to
prevent
exhaust
from
entering
a
building.
8.
Particles
from
flour,
aerosols,
and
other
contaminants
may
clog
the
air
vent
or
reduce
the
functions
of
the
rotating
fan
and
cause
improper
burning
of
the
gas.
Regularly
ensure
that
the
area
around
the
unit
is
dust
‐
or
debris
‐
free;
regular
maintenance
is
recommended
for
these
types
of
environment.
9.
If
you
will
be
installing
the
water
heater
in
a
contaminated
area
with
a
high
level
of
dust,
sand,
flour,
aerosols
or
other
contaminants/chemicals,
they
can
become
airborne
and
enter
and
build
up
within
the
fan
and
burner
causing
damage
to
the
water
heater.

For
the
Indoor
110
(T
‐
KJr2
‐
IN),
310
(T
‐
K4
‐
IN),
and
510
(T
‐
D2
‐
IN)
models:
•
These
units
may
be
converted
to
a
direct
‐
vent
(sealed
combustion)
appliance
by
installing
a
direct
‐
vent
conversion
kit
(Part
No.
9007667005)
which
will
bring
in
all
required
combustible
air
from
outside
the
building.
When
installing
the
conversion
kit,
please
follow
all
instructions
included
with
the
kit.
•
If
the
water
heater
is
used
as
a
direct
‐
vent
appliance,
the
unit
requires
a
3”
intake
air
pipe.
The
intake
pipe
must
be
sealed
airtight.
Air
supply
pipe
can
be
made
of
ABS
,
PVC,
galvanized
steel,
corrugated
aluminum,
corrugated
stainless
steel
or
Category
III
stainless
steel.
•
Terminating
the
venting
through
a
sidewall
is
recommended
for
the
direct
‐
vent
system.
•
Running
the
exhaust
vent
and
the
intake
pipe
parallel
is
recommended.
•
Terminating
the
exhaust
and
intake
on
the
same
wall
/
surface
is
recommended.
Terminating
in
the
same
pressure
zone
allows
for
pressure
balancing,
which
prevents
nuisance
shutdowns.
Follow
venting
clearance
guidelines
in
the
installation
manual.
