GAS CONNECTION
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.
Before installing the regulator mount the 1/2” NPT (conical) male connector to the regulator
The regulator supplied with this range must be installed before any gas connections are made.
Use supplied pressure regulator only.
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 or LP/PROPANE gas.
It is shipped from the factory adjusted for use with NATURAL gas.
d)
Manifold pressure should be checked with a manometer; NATURAL gas requires 4.0” W.C.P. and LP/PROPANE
requires 10.0” W.C.P.
Incoming line pressure upstream from the regulator must be 1” W.C.P. higher than the manifold pressure in order
to check the regulator.
The regulator used on this range can withstand a maximum input pressure of 1/2 PSI (14.0” W.C.P). 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
1/2 PSI (3.5 kPa).
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 supply piping system at test pressure equal to or less than
1/2 PSI (3.5 kPa).
3. Flexible Connections:
If local codes permit, CSA design-certified, flexible metal appliance connector is recommended for connecting this range to the gas
supply line. Do Not kink or damage the flexible connector when moving the range. The pressure regulator has 1/2” NPT female
pipe threads. You will need to determine the fittings required, depending on the size of your gas supply line, flexible metal
connector and shutoff valve.
4. Rigid Pipe Connections:
If rigid pipe is used as a gas supply line, a combination of pipe fittings must be used to obtain an in-line connection to the range.
All strains must be removed from the supply and fuel lines so range will be level and in line.
•
Use joint compounds and gaskets that are resistant to action of natural or propane gas on all male pipe threads.
•
Do not over tighten gas fitting when attaching to pressure regulator. Over tightening may crack regulator.
5. Leak Testing:
IMPORTANT: Leak testing of the appliance shall be conducted as follows:
•
After final gas connection is made, turn on manual gas valve and test all connections in gas supply piping and
appliance for gas leaks with a soapy water solution. During this test all appliance gas valves have to be closed.
•
In order to avoid property damage or serious personal injury, never use a Iighted match. If a leak is present, tighten joint or
unscrew, apply more joint compound, tighten again and retest connection for leak.
PRESSURE REGULATOR INSTALLATION
Note:
THE REGULATOR IS PRE-INSTALLED BY THE
FACTORY FOR YOUR CONVENIENCE.
THE FOLLOWING INSTRUCTIONS ARE FOR
INFORMATION PURPOSES ONLY OR IN THE
INSTANCE A PART MUST BE REPLACED.
WARNING
Check the right positioning of the gas regulator. The
arrow on the back of the gas regulator must be oriented
toward the connector.
