GAS SUPPLY CONNECTION
For proper installation of the 7400 and 7500 Series
Fryers, gas inlet pressure of at least 7.0"W.C. (Water
Column) for natural gas and 11.0"W.C. for propane gas
must be maintained while the unit is in operation. When
connecting unit gas supply, installation personnel must
install this equipment in accordance with all state and
local codes having jurisdiction. In the absence of local
codes, the National Fuel Gas Code ANSI Z223.1 (latest
edition) will apply.
NOTE:
1. The fryer and its individual shut off valve must be dis-
connected from the gas supply piping system during
any pressure testing of that system at test pressures in
excess of 1/2 psig (3.45 kPa).
2. The fryer 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
(3.45 kPa).
Each burner is controlled by a combination gas valve
pressure regulator. All 4 burner units are set for 5.5"W.C.
for natural gas and all 5 burner units are set for 5.3"W.C.
for natural gas. Both the 4 and 5 burner units are set for
10.0"W.C. for propane gas.
All gas supply connections any pipe joint compound used
must be resistant to the action of propane gases. Pipe
joints should be tested for leaks with a soap and water
solution before operation of unit.
UNITS MOUNTED ON CASTERS
Units mounted on casters utilizing a flex hose and quick
disconnect must be installed with a restraining device.
The restraining device must be connected at all times. If
disconnection of the device is necessary, reconnect the
restraint, after the unit has been returned to its original
installation position and before beginning unit operation.
In addition the quick disconnect device must comply with
the ANSI Z21.41 (latest edition) and ADDENDA, Z21.41 a
and Z21.41 b (latest editions) Standard for Quick Discon-
necting Devices used with Gas Fuel.
NOTE: All units on casters must be installed with a gas
connector that complies with the American National Stan-
dards ANSI Z21.69 (latest edition) and ADDENDA
Z21.69a (latest edition) for movable gas appliances.
ALL CASTER UNITS MUST BE INSTALLED PROVIDING
ADEQUATE MEANS TO LIMIT THE MOVEMENT OF THE
APPLIANCE WITHOUT DEPENDING ON THE CONNECTOR
AND ANY QUICK DISCONNECT DEVICE OR ITS
ASSOCIATED PIPING.
Installation of Unit Casters:
All 7400 and 7500 Series Fryers are shipped with casters
unmounted. Mounting casters to the unit will require (2) people.
After removing the fryer from the crate bottom carefully tilt fryer
to one side and install (2) casters front to rear utilizing (4) ea. of
the mounting bolts and hardware supplied. Repeat for other
side of fryer.
