Installation instructions 15

Leak testing

Leak testing of the appliance shall be conducted according to the manufacturer’s instructions.

The appliance and its individual shut-off valve must be disconnected from the gas supply piping system during any pressure testing of that system in excess of ½ psi (3.5kPa).

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 pressures at or less than ½ psi (3.5 kPa).

Maximum inlet gas supply pressure 20” W.C. (5 kPa)

Minimum gas supply pressure for regulator testing 5” W.C. Natural Gas, 12” W.C. LP Gas.

After installing the gas supply and making all connections, check thoroughly for possible leaks:

1Turn all control dials on unit to “off” position.

2 Open the valve on the gas supply.

3 Using a leak detection fluid (eg Rocol leak detection spray), check each gas connection one at a time by brushing the solution over the connection. The presence of bubbles will indicate a leak.

4 If necessary, tighten the fitting and recheck for leaks.

5 Turn on burner valve and light each burner.

6 Check for a clear blue flame without yellow tipping. If burners show any abnormalities, check that they are located properly and in line with the injector orifice.

Minimum setting or turn-down

After installation check the minimum setting. This has been preset at the factory for NG but needs to be checked and then reset if necessary. To adjust for minimum setting (if applicable), you will need a Ø 7⁄64 “ x 1 ¾” (Ø 2.5 x 45 mm) screwdriver.

(A suitable screwdriver is available as Fisher & Paykel spare part FB200467).

1Ignite the burner and set the dial to its minimum position.

2 Remove the dials.

3 Rotate the turn-down screw (down the hole in the spindle) while holding the shaft. Rotate slowly until a minimum regular flame is achieved. (The flame will diminish when the screw is turned clockwise and increase when turned counter-clockwise).

4 When the setting is right, check regulation by quickly

rotating the dial from the maximum to the minimum delivery position. The flame must not go out and the auto-reignition should not click. Replace the dial.
