Flexible Hose Connection;
If a Gas Hose assembly is used to connect
this appliance, the hose and all fittings
must have a
minimum
¾
” (Natural Gas) or ½” (LPG)
inside bore diameter to ensure gas flow
rate capacity
required by this appliance is achieved.
This must be verified by the operating
pressure testing at the maximum gas sup-
ply demand condition.
The Gas Hose assembly should also be
classified for use in the commercial kitch-
en conditions, the appliance will be used
in.
Recommended Gas Hose Assembly Spec-
ification:
- AS/NZS 1869 Class B or D compliant or

Gas Connection
NOTE:
ALL GAS FITTING MUST ONLY BE CARRIED OUT BY A
QUALIFIED SERVICE PERSON.
1. COBRA Model Fryers do not require an electrical
connection, they function totally on the gas
supply only.
2. It is essential that the gas supply is correct for the
appliance to be installed and that adequate
supply pressure and volume are available. The
following checks should therefore be made
before installation:-
a.
The Gas Type the appliance has been
supplied for is shown on coloured stickers
located above the gas entry point and next
to the rating plate. Check that this is correct
for the gas supply the appliance is being
installed for. The gas conversion procedure is
detailed in the Service Manual.
b. Supply Pressure required for this appliance is
shown in the “Specifications” section of this
manual. Check the gas supply to ensure that
adequate supply pressure exists.
c. Input Rate of this appliance is also stated on
the Rating Plate fitted to the inside of the
access door and in the “Specifications”
section of this manual. The input rate should
be checked against the available gas supply
line capacity.
Particular note should be
taken if the appliance is being added to an
existing installation.
NOTE:
It is important that adequately sized piping runs
directly to the connection joint on the appliance,
with as few tees and elbows as possible to give
maximum supply volume.
3. A suitable joining compound which resists the
breakdown action of LPG must be used on eve-
ry gas line connection, unless compression fit-
tings are used.
The connection to the appliance is
