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 oven. (Gas conversions are the responsibility
of the dealer or end user.)
c) This oven 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 11.0” W.C.P. (see figure below).
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.
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 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.
