SECTION
E
GAS
CONNECTION
1.
The gas
supply line shall
be
gas-tight,
sized
and so
installed
as to
provide
a
supply
of gas
sufficient
to
meet
the
maximum demand
of the
heater without loss
of
pressure.
2.
A
shut
off
valve should
be
installed
in the
upstream
of
the gas
line
to
permit
servicing.
3.
Flexible pipe
and any
appliance connector valve used
for
gas
piping
shall
be
types approved
by
nationally
recognized agencies.
4.
Any
compound used
on the
threaded joint
of the gas
piping
shall
be a
type which resists
the
action
of
liquefied petroleum gas.
5.
Supplied
gas
pressure must
be
within
the
limits shown
in
the
specifications.
6.
After completion
of gas
pipe
connections,
all
joints
including
at the
heater must
be
checked
for
gas-
tightness
by
means
of
leak detector
solution,
soap
and
water,
or an
equivalent nonflammable solution,
as
applicable.
CAUTION: Since some leak test solutions,
including
soap
and
water,
may
cause corrosion
or
stress
cracking,
the
piping
shall
be
rinsed with water after
testing,
unless
it has
been determined that
the
leak
test solution
is
noncorrosive.

7.
The
appliance
and its
appliance main
gas
valve must
be
disconnected
from
the gas
supply piping system during
any
pressure testing
of
that system
at
test pressures
in
excess
of 1/2
psi(3.5kPa).
The
appliance must
be
isolated from
the gas
piping
system
by
closing
its
equipment
shutoff valve during
any
pressure testing
of the gas
supply piping system
at
test pressure equal
to or
less than
1/2
psi(3.5kPa).
8.
A
1/8" test plug
is
provided
for
testing
of
manifold
pressure
see
schematic
for
location (page
26)
At
time
of
installation installer must supply
a
1/8"
N.P.T. plugged tapping, accessible
for
test gauge
connection, immediately upstream
of the gas
supply
connection
of the
appliance.
9.
The
minimum
and
maximum inlet
gas
supply pressure
are for the
purpose
of
input adjustment.
GAS
