Use a new CSA or UL approved gas supply line.
Install a shut-off valve.
Securely tighten all gas connections.
If connected to LP, have a qualified person make sure gas pressure does not exceed 14" water column.
Examples of a qualified person include licensed heating personnel, authorized gas company personnel, and authorized service personnel.
Failure to do so can result in death, explosion, or fire.
All gas connections must be made according to national and local codes. This gas supply (service) line must be the same size or greater than the inlet line of the appliance. Sealant on all pipe joints must be resistant to the action of LP/Propane gas.
The range is equipped for the use with NATURAL gas. It is design-certified by CSA International for NATURAL and L.P. gases with appropriate conversion.
The model/serial rating plate, located below the bottom drawer, has information on the type of gas that can be used. If this information does not agree with the type of gas available, check with the local gas supplier. See page from 16 to 19 for L.P. gas conversion instructions.
Manual Shut-off Valve (fig: 2.1)
A manual shut-off valve must be installed in an accessible location in the gas line external to the appliance for the purpose of turning on or shutting off gas to the appliance (In Massachusetts such shutoff devices should be approved by the Board of State Examiners of Plumbers & Gas Fitters).
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 (see picture 2.2).
Gasket supplied has to be placed between 1/2” NPT (conical) connector/extension pipe male pipe fitting (see picture 2.3).
The regulator supplied with this range must be installed before any gas connections are made.
Use supplied pressure regulator only.
Pressure Regulator Installation
Mount the 1/2” NPT (conical) male connector to the pressure regulator and tighten by using a wrench.
Assemble the 1/2” NPT connector + pressure regulator group to the extension pipe interposing the gasket supplied. The regulator cover must be oriented toward the front side of the range.
Gas Connection Specification
Check the correct positioning of the gas regulator.
The arrow on the back of the gas regulator must be oriented toward the connector.
If local codes permit, CSA or UL 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.
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 the 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 the pressure regulator. Over tightening may crack the regulator.
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.
Conversion to LP/Propane Gas (or conversion back to the original gas - Natural Gas)
Every range is provided with a set of orifices for the various types of gas.
Select the orifices to be replaced according to the “ORIFICES TABLE”.
The nozzle diameters, expressed in hundredths of a millimetre, are marked on the body of each orifice.
Save the orifices removed from the appliance for future use.
Setting the pressure regulator
The pressure regulator is accessible by removing the warmer drawer; the pressure regulator is positioned on the rear right side of the range ( fig. 2.9).
To remove the warming drawer:
To set the pressure regulator (fig. 2.9):
Fitting the warming drawer (fig. 2.10):
|Dual (D)||Inner crown||2100||1000||42 (*)||70 (*)|
|Inner & outer crown||17000||6500||115 (#)||200 (#)|
(*) inner crown (“J2” in figure 2.12)
(#) outer crown (“J3” in figure 2.12)
Operations to be performed when substituting the orifices
- Remove the pan supports, the burner caps and the flame spreaders.
- Dual burner only ( fig. 2.12): Unscrew the no.3 fixing screws “A” and remove the inner crown flame spreader “B”; then unscrew the no.2 fixing screws “C” and remove the cover plate “D”.
- Using a wrench substitute the nozzle orifices “J1”, “J2” and “J3” ( figs. 2.11, 2.12) with those most suitable for the kind of gas for which it is to be used.
- Dual burner only ( fig. 2.12): Refit the cover plate “D” and screw the no.2 fixing screws “C”; then refit the inner crown flame spreader “B” and screw the no.3 fixing screws “A”
- Refit the flame spreaders, the burner caps and the pan supports.
The burner are conceived in such a way so as not to require the regulation of the primary air.
Setting the burner minimum
When switching from one type of gas to another, the minimum ow rate must also be correct: the flame should not go out even when passing suddenly from maximum to minimum flame.
To regulate the flame ( fig. 2.13) follow the instructions below:
Light the burner.
Set the gas valve to position (minimum rate).
Remove the knob.
With a thin screwdriver, turn the regulation screw “R1” until adjustment is correct.
Inside crown of DUAL burner
Light the DUAL burner.
Set the gas valve to position (minimum rate of inner crown).
Remove the knob
With a thin screwdriver, turn the regulation screw “R2” until adjustment is correct.
Outside crown of DUAL burner
Light the DUAL burner.
Set the gas valve to position (minimum rate of inner and outer crowns).
- Remove the knob.
- With a thin screwdriver, turn the regulation screw “R3” until adjustment is correct.
For LP/PROPANE gas, tighten the adjustment screws completely.
After regulation repeat the operations indicated in paragraph "2. PRESSURE REGULATOR" at page 12 and 15
If the range has been disconnected and then connected again to the gas supply line repeat the operations indicated in paragraph “5. LEAK TESTING” at page 15.
- After conversion to LP/PROPANE gas has been carried out affix near the data plate the conversion label supplied and also affix a conversion label at page 3 of this instruction manual
- After conversion back to the original gas (NATURAL GAS) has been carried out remove, near the data plate and at page 3 of this instruction manual, the LP/PROPANE conversion labels. Save the labels removed for future use
