INSTALLATION INSTRUCTIONS
LEAK TESTING | MINIMUM SETTING OR TURNDOWN |
US
Leak testing of the appliance shall be conducted according to the manufacturer's instructions.
The appliance and it's individual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system in excess of 1/2 p.s.i. (3.5kPa). The appliance must be isolated from the gas supply piping system by closing it's individual manual shutoff valve during any pressure testing of the gas supply piping system at test pressures at or less than 1/2 p.s.i.(3.5kPa).
Maximum inlet gas supply pressure 4" W.C. Natural Gas, 11" W.C. LP gas.
Minimum gas supply pressure for regulator testing 5" W.C. Natural Gas, 12" W.C. LP gas.
This has been set at the factory for NG but can be checked after the correct pressure has been reached. To adjust for minimum setting (if applicable), you will need a Ø 7/64 " x 1 3/4" (Ø2.5 x 45mm) screwdriver. (A suitable screwdriver is available as Fisher & Paykel spare part. FB200467).
1Ignite the burner and set the knob to its minimum position.
2Remove the knobs.
3Rotate 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).
After installing the gas supply and making all connections check thoroughly for possible leaks.
1Turn all control knobs on unit to "off" position.
2Open the valve on the gas supply.
3Using a leak detection fluid (e.g. 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.
4If necessary, tighten the fitting and recheck for leaks.
5Turn on burner valve and light each burner.
6Check 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.
4When the setting is right check regulation by quickly rotating the knob from the maximum to the minimum delivery position. The flame must not go out and the autoreignition should not click. Replace the knob.
