GAS CONNECTIONS
The gas supply (service) line must be the same size or greater than the inlet line of the appliance. This range
uses a ½" I.D. NPT (Sch40) inlet. Sealant on all pipe joints must be resistive to Lp gas.
1.
Manual Shut-off Valve:
This installer supplied valve must be installed
in the gas service line ahead of the appliance
and regulator in
a position where it can be
reached quickly in the event of an emergency
.
2. Pressure
Regulator:
a
) All heavy-duty, commercial-type cooking
equipment must have a pressure regulator on
the incoming service line for safe and efficient
operation, since service pressure may fluctuate
with local demand. External regulators are not
required on this range, because a regulator is
built into each unit at the factory.
UNDER NO
CONDITION BYPASS THIS BUILT-IN
REGULATOR.
b
)
Any conversion required must be performed
by your dealer or a qualified licensed plumber
or gas service company. Please provide the
service person with this manual before work
is
started on the range
.
( GAS CONVERSIONS ARE THE
RESPONSIBILITY OF THE DEALER OR
END USER.)
c
) This range can be used with Natural gas or
LP/Propane. It is shipped from the factory
adjusted for use with natural gas. The orifice
hoods must be screwed snug when
LP/Propane is used. (See LP/Propane
conversion).
d
) Manifold pressure should be checked with a
manometer, natural gas requires 5.0"WC and LP
gas requires 10.0"WC. Incoming line pressure
upstream from the regulator must be 1.0"WC
higher than the manifold pressure in order to
check the regulator. The regulator used on this
range can withstand a maximum
input pressure
of ½ PSI (14.0" WC). If the line pressure is
in excess of that amount, a step-down
regulator will be required.
e
) The appliance, its individual shut-off valve,
and pressure regulator must be disconnected
from the gas supply piping system during any
pressure testing of that system at pressures in
excess of 1/2psig (3.45kPa).
f
) The appliance must be isolated from the gas
supply piping system by closing its individual
manual shut-off valve during any pressure testing
of the gas piping system at test pressures equal to
or less than ½ psig (3.45kPa).
3. Flexible
Connections:
a
) If the unit is to be installed with flexible
couplings and/or quick-disconnect fittings, the
installer must use a heavy duty, A.G.A. design
certified commercial flexible connector of at least
½" ID NPT ( with suitable strain reliefs) in
compliance with ANSI Z21.69.
b
)
In Canada
: CAN 1-6. 10-88 metal
connectors for gas appliance and CAN 1-6.9
M79 quick disconnect devices for use with gas
fuel.
