Step 5 Gas Requirements and Hookup
Verify the type of gas being used atthe installation
site.
As shipped
from the factory,
units are configured
for use with only natural
gas or propane
(LP) gas.
Make certain
the range
matches
the type
of gas
available
at this
location.

ranges
are NOT
convertible
between
different
types
of gas.
For installation
of the appliance
at high altitude, please
consult
your local gas company
for their recommen-
dation
of the
correct
orifice
sizes
and
any other
necessary
adjustments
that will provide
proper
gas
combustion
at specified
altitudes.
CAUTION
When
connecting
unit to propane
gas, make
certain the propane gas tank is equipped
with its
own high pressure
regulator
in addition
to the
pressure
regulator
supplied
with the appliance.
The pressure
of the gas supplied
to the appli-
ance regulator
must not exceed
14" (34.9
mb)
water
column.

HOOK
UP
A manual
gas shut-off
valve
must
be installed
external to the appliance,
in a location accessible
from the front, for the purpose
of shutting
off the
gas supply. The supply line must not interfere with
the back of the unit. Make sure the gas supply is
turned
off at the manual
shut-off
valve
before
connecting
the appliance.
The range is supplied
with its own pressure
regu-
lator that has been permanently
mounted
within
the range body.
Use 3/4" flex line to connect
between
the gas
supply
and the appliance
manifold
pipe, which
exits the upper rear of the appliance.
The appli-
ance inlet pipe connection
is 1/2" N PT. (See Photo
A.) Use caution to avoid crimping
the 3/4" flex line
when making bends. Suggested
length of flex line
is 48", however,
please check local codes for your
area's requirements
before
installation.
The gas supply connections
shall be made by a
competent
technician
and in accordance
with
local codes or ordinances.
In the absence of local
codes, the installation
must conform to the National
Fuel Gas Code ANSI Z223.1iNFPA
54- current
issue.
Always
use pipe sealing
compound
or Teflon@
tape on the pipe threads,
and be careful
not to
apply
excessive
pressure
when
tightening
the
fittings.
Leak testing
of the appliance
shall be in accor-
dance with the following
instructions.
• Turn on gas and check supply line connections
for leaks using a soap and water solution.
• Bubbles
forming
indicate
a gas leak. Repair all
leaks immediately
after finding
them.
• Do not use a flame
of any kind to check
for
gas meaks.
