CAUTION! When connecting unit to Propane (LP)
gas, make certain the propane 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 appliance
regulator must not exceed 14” (37 mb) water
column.
NATURAL GAS REQUIREMENTS:
• Inlet Connection: 1/2” N.P.T.
• Min. 5/8” Dia. Flex Line.
• Supply Pressure: 6” to 14” W.C.
PROPANE (LP) GAS REQUIREMENTS:
• Inlet Connection: 1/2” N.P.T.
• Min. 5/8” Dia. Flex Line.
• Supply Pressure: 11” to 14” W.C.
• A Regulator is required at the LP source to provide
a maximum of 14” W.C. pressure to the range
regulator.
WARNING! Gas line cannot be run inside back
cover of range. Run gas line in channel in back
of range.
HOOK UP
• A manual shut off valve must be installed external
to the range in an accessible location from the front
for shutting off the gas supply when required.
• The supply line MUST NOT protrude beyond the
back of the range.
• Ensure that the gas supply is turned OFF at the
external shut-off valve before connecting the range.
• The gas supply connection must be made by an
experienced technician and in accordance with
local codes or ordinances. In the absence of local
codes or ordinances, please refer to National Fuel
Gas Code ANSI Z223.1 / NFPA54-Current Issue.
• The range is supplied with its own pressure regulator
that has been permanently mounted with the range body.
• Use 5/8” diameter flex line to connect between the
gas supply and the appliance manifold pipe, which
exists at the upper left rear of the appliance. The
appliance manifold pipe connection is 1/2”. Use
caution to avoid crimping the 5/8” flex line.
• NOTE: the flex line for the gas supply must be metal
and approved by an approved certifying agency
(AGA, CGA, CSA, UL or CUL). NEVER use a hose
made of rubber or other synthetic material as the
heat may cause the hose to melt and develop leaks,
thus causing fires, physical and property damage.
• Always use pipe dope 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 accordance
with the manufacturer’s instructions.
• Turn on gas and check supply line connections for
leaks using a soap solution.
Do not use a flame of
any sort to test for leaks.
CAUTION! The appliance must be isolated from the
gas supply piping system by closing its individual
manual shut-off valve during any pressure testing
of the gas supply piping system at test pressures
equal to or less than 1/2 psig (3.5kPa.).
The Appliance and its individual shut off valve
must be disconnected from the gas supply piping
system during any pressure testing of the system
at test pressures in excess of 1/2 psig (3.5kPa.).
When checking the manifold gas pressure, the inlet
pressure to the regulator should be at least 6.0”.
DO NOT attempt any adjustment of the pressure
regulator.
TESTING AND ADJUSTMENTS
Install any loose components, such as burner caps
and grates, oven racks that may have been removed
earlier to facilitate moving the appliance. Be certain
that burner caps seat properly into the alignment
slots in the burner bases. Before testing operation
of the appliance, verify that the unit and the gas
supply have been carefully checked for leaks and
that the unit has been connected to the electrical
power supply. Turn the manual gas shut-off valve to
the open position. Check the operation of the sealed
gas burners and grill by pushing and turning each
knob counterclockwise to “HI”. The burner igniters
will click until the flame ignites.
Burner flames should be BLUE and stable with
no yellow tips, excessive noise, or lifting of the
flame from the burner. If any of these conditions
exist, check that the air shutter (grill and griddle
only) or burner ports are not blocked or clogged.
Remove any blockages that exist. If the flame is too
yellow, indicating insufficient air, adjust the shutter
counterclockwise to increase air inlet (grill and
griddle only).
The sealed top burner flames should be
approximately 1” to 1-1/4” High. The griddle and
grill flames should be as shown in the figure below.
CAUTION! A qualified technician must make
burner adjustments at the time of installation.
Improper or lack of adjustments may cause harmful
by-products or void your warranty!
