GAS CONNECTION
All gas connections must comply with
national and local codes. The gas supply line
(service) must be the same size or greater
than the inlet line of the appliance. This
range uses a 1/2" NPT inlet (see drawing
below for details of gas connection). On all
pipe joints use appropriate sealant resistant
to gas.
This range can be used with Natural or LP/
Propane gas. The range is shipped from the
factory for use with natural gas.
For LP/propane household installation, the
appliance must be converted by the dealer,
by a factory-trained professional or by a
qualified licensed plumber or gas service
company.
Gas conversion is important for safe and
effective use of the appliance. It is the
responsibility of the dealer and the owner of
the range to perform the appropriate gas
conversion following the directions of the
manufacturer.
THE PROPER GAS CONVERSION
PROCEDURE IS DESCRIBED IN THIS
MANUAL. REPLACEMENT NOZZLES
CAN BE PURCHASED FROM
COSMOAPPLIANCES.COM.
Please provide the service person with this
manual before work is started on the range.
WARNING: DO NOT USE AN OPEN
FLAME WHEN CHECKING FOR LEAKS.
Leak testing of the appliance shall be
conducted according to the manufacturer's
instructions. Before placing the oven into
operation, always check for leaks with soapy
water solution or other acceptable method.
Check for gas leakage with soapy water
solution or other acceptable methods in all
gas connections installed between inlet gas
pipe of the appliance, gas regulator, till to the
manual shut-off valve.
MANUAL SHUT-OFF VALVE
THIS VALVE IS NOT SHIPPED WITH THE

this appliance.
FLEXIBLE CONNECTIONS
In case of installation with flexible couplings and/
or quick-disconnect fittings, the installer must use
a heavy-duty, AGA design-certified commercial
flexible connector of at least 1/2" (1.3 cm) ID NPT
(with suitable strain reliefs) in compliance with
ANSI Z21.41 and Z21.69 standards.
In Massachusetts: The unit must be installed

for gas appliances and CAN 1-6.9 M79 quick
disconnect device for use with gas fuel.
PRESSURE TEST-POINT STOPPER VALVE
To avoid gas leaks, the pressure test-point
