Pressure Regulator; Flexible Connections; Leak Testing - GASLAND chef Pro GS606MS Installation Instructions Manual

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.
b) The oven is suitable for the use of natural gas.
c) Manifold pressure should be checked with a manometer; NATURAL gas
requires 4.0" 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 oven 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.
d) 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).
e) 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 oven to the gas supply line. Do Not kink or
damage the flexible connector when moving the oven. The pressure regulator has
3/8" 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 oven. All strains must be removed from
the supply and fuel lines so oven 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 connec-
tions 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.
