Note: when tightening the connection, make sure you hold it firmly in position (eg by using adjustable pliers or an adjustable wrench) and take care not to damage the thread. 2 Connect the extension pipe to the elbow: Mount the extension pipe to the elbow connection, making sure you place the supplied washer between them. Note: when tightening the connection, make sure you hold it firmly in position (eg by using adjustable pliers or an adjustable wrench) and take care not to damage the thread. 3 Prepare the gas pressure regulator: Mount the 3/8” NPT (conical) male connector to the gas pressure regulator and tighten by using a wrench. Note: take care not to overtighten the connector, as doing so may crack the gas pressure regulator. 4 Connect the gas pressure regulator assembly to the extension pipe: Mount the gas pressure regulator assembly to the extension pipe, making sure you place the supplied washer between them (see Fig. 11). Important! Use two wrenches to tighten the connection.

Flexible hose connections If local codes permit, CSA design-certified, flexible metal appliance connector is recommended for connecting this cooktop to the gas supply line. Do not kink or damage the flexible connector when moving the cooktop. The gas 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 shut-off 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 cooktop. All strains must be removed from the supply and fuel lines so the cooktop will be level and free of pressure from the piping. Use joint compounds and washers resistant to the action of all gas types on all male pipe threads. Do not overtighten the gas fitting when attaching it to the gas pressure regulator, as doing so may crack the regulator.

During leaktesting, all the gas valves on the cooktop must be closed. The presence of bubbles indicates a leak. If a leak is present, tighten or replace connections as appropriate. Important! Do not use any naked flame to check for leaks. Converting the cooktop to a different gas type Important! The conversion procedure must be carried out only by an authorized person. This appliance is supplied with a set of injectors for the various types of gas. Use the ‘Gas rate summary’ (following) to select the appropriate injector. To convert from one gas type to another, you need to reset the gas pressure regulator, replace the injectors, adjust the minimum burner setting, re-test for leaks and fill in/affix the gas conversion labels. 1 Reset the gas pressure regulator: Unscrew the regulator cover and remove it. Unscrew component “A”, reverse it and screw it back in according to the gas type you are converting to (see Fig. 14 below). 2 Replace the injectors: Remove the grates, burners and the control knobs. Using a wrench, replace the injectors with those suitable for the kind of gas you are converting the cooktop to. See the ‘Gas rate summary’ (following). Note: the burners are designed so that regulation of primary air is not required.
