D. GAS CONNECTION:
The gas supply (service) line must be the same size or greater than the inlet line of the appliance.
THE GAS
SUPPLY LINES MUST BE SIZED TO ACCOMMODATE ALL THE GAS FIRED EQUIPMENT THAT MAY BE CONNECTED
TO THAT SUPPLY.
Refer to the Inlet Gas Line Sizing Table and inlet gas requirements on page 6.
NOTE:
Sealant used on all pipe joints must be resistive to butane and propane gas.
1. Manual shut off valve: This supplier-installed valve must be installed in the gas service line ahead of the appliance and in a
position where it can be reached quickly in the event of an emergency.
2. Pressure regulator: All commercial cooking equipment must have a pressure regulator on the incoming service line for safe
and efficient operation, because service pressure may fluctuate with local demand. External regulators are not required on this
fryer, as that function is performed by a combination gas control valve, however if the incoming pressure is in excess of 1⁄2 psig,
a step-down regulator will be required.
3. Natural gas: Natural gas fryers require 7” (178mm) water column (W.C.) “inlet” pressure to the fryer’s combination gas con-
trol valve for
proper operation, when all gas units are operating simultaneously. Butane and Propane gas fryers require 14”
(356mm) water column (W.C.) “inlet” pressure to the fryer’s combination gas control valve for proper operation, when all gas
units are operating simultaneously. This “inlet” pressure
MUST
be checked with a manometer
PRIOR
to placing the fryer in
operation.
WARNING: IF THE “INLET” GAS PRESSURE AT THE FRYER’S COMBINATION GAS CONTROL VALVE “EXCEEDS” 1⁄2 lb/in2
(.035 kg/cm2) OR APPROXIMATELY 14” (356 mm) W.C., AN EXTERNAL REGULATOR MAY BE NEEDED TO PRE
VENT DAMAGE TO THE COMBINATION GAS VALVE, AND VOIDING OF WARRANTY. FAILURE TO ADDRESS
THIS COULD RESULT IN AN EXPLOSION OR A FIRE.
4. Combination gas control valve: The correct combination as control valve and orifice is installed at the factory for
BUTANE,
NATURAL
and
PROPANE
units based on each Purchase Order. This valve should be
CHECKED/ADJUSTED
by qualified
service personnel using proper test equipment for the following “
OUTLET
” gas pressure
PRIOR
to start-up of a fryer.
NATU-
RAL GAS FRYERS 4” (102mm) W.C. BUTANE/PROPANE FRYERS 10” (254mm) W.C.
5. Rigid connections: Check any installer-supplied intake pipe(s) visually and/or blow them out with compressed air to clear dirt
particles, threading chips or any other foreign matter before connecting to the service line as these particles may clog the ori-
fice when gas pressure is applied. All connections must be tested with a soapy solution before lighting the fryer.
DO NOT
USE AN OPEN FLAME TO CHECK FOR LEAKS!
Putting an open flame beside a new connection is not only dangerous,
but will often miss small leaks that a soapy solution would find.
6. Flexible Couplings, Connectors: The installation is to be made with a connector that (1) complies with the
Standard for Con-
nectors for Movable Gas Appliances, ANSI Z21.69 (CAN/CGA-6.16)
, and a quick-disconnect device that complies with the
Standard for Quick- Dis-connect Devices for Use With Gas Fuel, ANSI Z21.41 (CAN1-6.9)
(2) adequate means must be
provided to limit the movement of the appliance without depending on the connector and the quick dis-connect device or its
associated piping to limit the appliance movement and (3) the location(s) where the restraining means may be attached to the
appliance shall be specified.
DOMESTIC CONNECTORS ARE NOT SUITABLE!!!
7. Fryer Service: The fryer is equipped with swivel casters. To service the fryer:
a) Turn “OFF” gas supply at the supply source.
b) Disconnect the flexible gas line quick-disconnect
c) Disconnect restraint means and roll fryer out for rear service access.
d) When the fryer is re-positioned, be sure to reconnect the restraint and level the fryer.
E. ELECTRICAL CONNECTION:
The
MAXIMUM
current draw per vat at Initial Start-up or during a Warm-up Cycle will be 3
Amperes at 120 Volts. When running the Filter System simultaneously allow for an additional 3 Amperes. Refer to the wiring
diagram attached to the inside of the Service Access door for internal electrical connections.
