2-6. GAS SUPPLY
(Continued)

•
The fryer must be isolated from the gas supply piping
system by closing its individual manual shutoff 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) (34.47mbar).
•
A standard 3/4 inch, black steel pipe and malleable
fittings should be used for gas service connections.
•
Do not use cast iron fittings.
•
Although 3/4 inch size pipe is recommended, piping
should be of adequate size and installed to provide a
supply of gas sufficient to meet the maximum demand
without undue loss of pressure between the meter and
the fryer. The pressure loss in the piping system should
not exceed 0.3 inch water column.
Provisions should be made for moving the fryer for cleaning
and servicing. This may be accomplished by:
1.
Installing a manual gas shut off valve and disconnect
union, or
2.
Installing a heavy duty (min. 3/4 inch) design A.G.A.
certified connector which complies with standard connec-
tors for moveable gas appliances. ANSI Z21.69 or
CAN/CSA 6.16. Also, a quick disconnect coupling which
complies with the Standard for Quick Disconnect De-
vices for use with Gas Fuel, ANSI Z21.41 or CAN 1-6.9.
Also, adequate means must be provided to limit the
movement of the fryer without depending on the connec-
tor and any quick-disconnect device or it's associated
piping to limit the fryer movement.
3.
See the illustration on the following page for the
proper connections of the flexible gas line and cable
restraint.
The cable restraint limits the distance the fryer can be pulled
from the wall. For cleaning and servicing the fryer, the cable
must be unsnapped from the unit and the flexible gas line
disconnected. This will allow better access to all sides of the
fryer. The gas line and cable restraint must be reconnected
once the cleaning or servicing is complete.
