Gas Connection

Information on connecting the Gas.

WARNING! 

Explosion Hazard.png

Explosion Hazard

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 on the back of the appliance, 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 13 to 15 for L.P. gas conversion instructions.

1. Manual Shut-off Valve (fig:2.1):

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). This valve should be located in the same room as the range and should be in a location that allows ease of opening and closing (in a position where it can be reached quickly in the event of an emergency).

Do not block access to the shutoff valve. The valve is for turning on or shutting off gas to the appliance.

2. Pressure Regulator Installation

STEP 1

Mount the 1/2” NPT (conical) male connector to the pressure regulator and tighten by using a wrench.

Do not over tighten the connector. Over tightening may crack regulator.

STEP 2

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.

use two spanners to tighten the connection.

  1. 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.)
  2. This range can be used with NATURAL or LP/PROPANE gas. It is shipped from the factory adjusted for use with NATURAL gas.
  3. Manifold pressure should be checked with a manometer and by operating as below detailed:
    • Remove the injector from the front left burner and mount the proper test point adapter which is available from the After-Sales Service (see side figure and the “OPERATIONS TO BE PERFORMED WHEN SUBSTITUTING THE INJECTORS” chapter).

    • Turn the front left burner control knob to the maximum position HI.

    • Press the knob and keeping it pressed check the manifold pressure with a manometer; NATURAL gas requires 4.0” W.C.P. and LP/PROPANE requires 11.0” 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.

  4. 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).
  5. 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:

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 Lighted match. If a leak is present, tighten joint or unscrew, apply more joint compound, tighten again and retest connection for leak.

Conversion to LPG/Propane Gas

Every range is provided with a set of injectors for the various types of gas.

Select the injectors to be replaced according to the “INJECTORS TABLE”.
The nozzle diameters, expressed in hundredths of a millimetre, are marked on the body of each injector.

Setting the pressure regulator (fig. 2.6)

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:

  1. Open the drawer completely (fig. 2.6)
  2. Move down the lever of left guide (fig. 2.7) and up the lever of right guide (fig. 2.8). 3. Remove the drawer; the levers have to be keep moved (fig. 2.6).

To set the pressure regulator (fig. 2.9):

  1. Unscrew the regulator cover;
  2. Unscrew the A component, reverse and screw it according to the LP/PROPANE regulation.

Fitting the warming drawer (fig. 2.10):

  1. Insert the drawer guides into the range guides (fig. 2.10)
  2. Gently close the drawer completely; the safety catchs will be automatically hooked.

Operations to be performed when substituting the injectors

  • Remove the gratings, the burner covers and the knobs;
  • Using a wrench substitute the nozzle injectors “J” (figs. 2.11 - 2.12) with those most

suitable for the kind of gas for which it is to be used.

The burner are conceived in such a way so as not to require the regulation of the primary air.

Setting the burner minimum (Valves may vary)

When switching from one type of gas to another, the minimum flow rate must also be correct: the flame should not go out even when passing suddenly from maximum to minimum flame.
To regulate the flame follow the instructions below:

  • Light the burner
  • Set the gas valve to LO position
  • Remove the knob
  • With a thin screwdriver, turn the regulation screw until adjustment is correct (Fig. 2.13a or 2.13b). On some valves, you need to pass by the hole of the microswitch (Fig. 2.13a) to turn the regulation screw.

For LP/PROPANE gas, tighten the regulation screws completely.

After regulation repeat the operations indicated in paragraph “2. Pressure regulator” at page 9 and 12. 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 12.

After conversion to LP/PROPANE gas has been carried out affix on the back of the appliance, near the data plate, the conversion label supplied and also affix a conversion label at page 3 of this instruction manual.
